Common types of coffee in daily life.

Instant Coffee

Including powdery, granular and low-temperature quick freezing in recent years. For example, Nestle's (in fact, most people who come into contact with coffee for the first time start to dissolve as soon as possible), the brewing is simple, just heat the water. But it lacks the richness and diversity of taste; It is reported that instant coffee contains more carcinogens.

Single product coffee (black coffee)

Black coffee usually refers to single coffee made by filtration. More broadly, all pure coffee without other ingredients can be called black coffee. That's the black one, divided into Blue Mountain, Brazil, Mantening and so on. Coffee shops generally use mocha coffee pots (stainless steel or aluminum, divided into upper and lower parts) or glass siphon coffee pots (upper and lower two glass balls) for brewing; Usually, only a single variety of coffee with relatively high quality is suitable for making single product (single variety) coffee.

Espresso

Made by a professional large espresso machine, it has a strong flavor and is usually packed in a special thick cup. Small weight, concentrated is the essence! It's equivalent to kungfu tea in coffee. A good cup of espresso has a thick creamy substance on its surface called Crema. The best is the leopard print in brown ointment, which belongs to the essence of coffee.

Decorative coffee

Generally, it is made by adding milk foam, syrup and cinnamon on the basis of espresso, such as cappuccino, latte and caramel macchiato.

Here are some classic coffees for you.

Espresso is made for you.

Espresso is Italian, which means to cook for you right away. The impulse brought by coffee is beyond words. Espresso is no longer a simple espresso. It is a comprehensive coffee, a baking method, a coffee cooking method, a dish and a life.

Italy strictly follows the extraction conditions of espresso. 9 bar pressure, 90.5 degrees Celsius, 14~25g fresh coffee powder, 25-30 seconds to complete the extraction, and extract 25 cc coffee essence. It takes more than a few hours to finish the aroma sweetness in one bite.

Two or three cups of espresso a day is the focus of Italian life. Italian style seems to be as strong as their lovers and will never leave. In the morning, they will have a latte (made of milk and espresso) at home first. Then go to the store and ask for an espresso and have a few drinks at the bar. While waiting, you can talk to people, and even the coffee master joins in at this time, making the cafe a small social world.

Their comments on American and Japanese coffee are: You seem to be drinking coffee water, not coffee. Italians often say: life should be as strong and energetic as espresso. Friends who like coffee should really try it when they have a chance to make sure you will fall in love with it.

Warning: espresso is so attractive, but because of its strict requirements on extraction conditions, most cafes cannot make espresso that can be imported. So it is strongly recommended that you don't order espresso in a strange bar unless you are in an Italian town.

A perfect espresso always has a thick chestnut surface. Crema is an aromatic component such as protein and oil extracted from coffee under high pressure, which is the essence of coffee concentration.

The perfect espresso, the perfect crema, first needs freshly roasted coffee beans. In the case of correct operation, if it turns golden or even white, it means that the coffee has been put for too long and has expired; If you can name the drinking period after baking again, it is 2 weeks under the condition of good preservation. Perhaps it is because I haven't tasted filtered black coffee without sugar or creamer for a long time, so it seems that more people only drink espresso when drinking espresso.

Of course, if the extracted espresso is very mellow, you won't feel bitter even if you drink pure espresso. However, according to the current coffee industry standards, the brewed coffee can only be drunk with sugar, whether it is mixed with coffee beans or taken out. Therefore, it is recommended that you drink with sugar, so that you can experience the fragrance and delicious taste after completion.

Italians who love sweets even add so much polysaccharide that it will remain at the bottom of the cup when drinking! Even if you don't add that much, as long as you add sugar, the sweetness will make the whole cup of coffee softer, more mellow and deeper, like tasting bitter chocolate. And after drinking it, it will leave a pleasant aftertaste in the nasal cavity.

The practice of latte coffee

Latte coffee is a classic mixture of Italian espresso and milk, and Italians also like lattes as breakfast drinks. In the Italian kitchen in the morning, coffee and milk are usually cooked at the same time on a sunny stove. Italians who drink lattes prefer milk to espresso, and only espresso can bring unforgettable taste to ordinary milk. A regular latte consists of one-third espresso and two-thirds fresh milk, usually without foam. Compared with cappuccino, its fresh milk flavor is more intense. Because latte has more milk and less coffee, it is very different from cappuccino.

The method of latte is extremely simple, that is, pour the nearly boiling milk into the freshly made espresso. In fact, there is no certain regulation on how much milk to add, and it can be freely allocated according to personal taste. American latte, the bottom layer is espresso, the middle is milk heated to 65 ~ 75℃, and the top layer is foamed cold milk foam. An iced latte is a mixture of fructose and milk to increase the proportion of milk, so that it will not be mixed with coffee with a low proportion, but will become two distinct layers of black and white, forming a beautiful visual effect like a cocktail. You can also add various flavors of juice to the latte to change the taste, such as caramel flavor, hazelnut flavor and French vanilla flavor.

Macchiato, caramel macchiato.

In Italian cafes all over the world, we can often see and hear Macchiato, a word with strong Italian flavor. It can be said that coffee made the ancient word Macchiato go to the world.

Macchiato means "imprint" in Italian. As the name implies, its name Macchiato symbolizes the sweet mark. The classic macchiato is decorated with small milk bubbles on a small cup of espresso. This is also the source of vitality that Italians must drink every day.

Macchiato can also be a milk coffee. It is made by mixing milk and vanilla syrup, then adding milk foam, then pouring coffee, and finally sprinkling grid caramel on the milk foam. Macchiato is usually used as the name of caramel macchiato.

Many people like caramel macchiato because of its sweetness. It is different from strong mocha coffee. It's gentle. If mocha is like dark chocolate, then Macchiato is toffee, giving people a soft feeling. Moreover, after the delicate milk foam is combined with caramel, it is delicate and smooth as a cloud. So Macchiato is usually a girl's favorite.

Macchiato is still iced, but iced Macchiato has no milk bubbles. It is suggested to add a layer of cream when drinking iced macchiato in summer, so that caramel can be poured on the cream, giving the light cream another flavor. The entrance is cold and sweet, smooth and refreshing. Girls who love ice cream must not miss it.

Macchiato wine is also very popular in Asia, and it is most popular with young people.

Caramel Macchiato: This is the world-famous flagship product of Starbucks. Sweet and mellow caramel macchiato is a good choice for coffee lovers to taste espresso. Vanilla syrup with smooth hot milk, smooth milk bubbles, mellow espresso mixed with soft caramel sauce.

Mocha coffee is an ancient and modern coffee.

Sitting in a coffee shop, flipping through the menu and flipping through coffee magazines, you will inadvertently encounter many mocha, which is simple but has many meanings. Authentic "Mocha Coffee" is only produced in Yemen, southwest of Arabian Peninsula, and grows on a steep mountainside at an altitude of 3,000 to 8,000 feet. It is also the oldest coffee in the world.

Generally speaking, the earliest mocha refers to a kind of coffee bean exported from Mocha Port in Yemen. As early as 500 years ago, Yemen produced coffee in an ancient way. It is produced in Ethiopia, Africa, and it is the most sour coffee. Mocha coffee is also called Ethiopian coffee. /kloc-At the beginning of the 0/7th century, the first batch of Yemeni coffee sold to Europe was exported through the ancient small port of Mocha, which surprised Europeans. The delicious coffee shipped from Mocha Port is called Mocha Coffee, which is also the origin of Mocha Coffee's name.

At present, Yemen produces the best coffee, followed by Mocha in Ethiopia. Mocha coffee belt has mild to strong lubricity, excellent sweetness, unique flavor and chocolate flavor; With the temperament of a lady, it is a unique pure coffee. With the birth of Italian fancy coffee, people try to add chocolate to ordinary coffee instead of mocha coffee, which is the fancy mocha that everyone can often drink now.

Italian fancy mocha coffee is made by mixing 1/3 espresso with 2/3 hot milk and adding chocolate. Traditional Italian fancy mocha coffee uses chocolate pulp as raw material, but later, due to the popularity of mocha coffee, more homemade mocha coffee uses chocolate powder instead of chocolate pulp.

Besides dark chocolate, milk chocolate can also be used as one of the materials of mocha coffee today. Unlike the thick milk foam of cappuccino, mocha has no milk foam at the top, but fresh cream, with cocoa powder and cinnamon added. Candied fruit is also used as an ornament of mocha coffee and placed on it. So mocha coffee is actually a general term for mocha bean coffee and fancy mocha coffee.

Simple family practice of mocha coffee

Mocha coffee is actually a variant of latte, which is similar to the classic combination of one-third espresso and two-thirds milk of latte, except that some chocolate is added.

Method for making mocha coffee:

1. Use 7 grams of coffee powder and extract 25CC of espresso with an Italian coffee machine. Instant coffee can be used for home cooking.

2. Take 200ml milk and add 10g cocoa powder. Heat with a steam pipe. There is no steam pipe at home, so you can heat the milk in the microwave oven and then melt the cocoa powder.

3. Pour cocoa milk into a coffee cup, sprinkle with cocoa powder or squeeze flowers with chocolate sauce for decoration.

If you don't have cocoa powder at home, you can also use malt extract, or mix milk with two pieces of chocolate, heat it in the microwave oven and melt it, and mix it with coffee. The simplest method can even use a small amount of milk and two small pieces of chocolate to melt, then add instant coffee powder and pour it into hot milk.

Heart-shaped Cappuccino-Romantic Coffee for Valentine's Day

Coffee is synonymous with romance. At the beginning of the 20th century, when the Italians invented the steam coffee machine, they also developed cappuccino. Cappuccino is an Italian coffee which is a mixture of espresso and steamed foamed milk. At this time, the color of coffee, like the monks in cappuccino church wearing headscarves on dark brown coats, gave the name coffee. Traditional cappuccino is one-third espresso, one-third steamed milk and one-third foamed milk.

Production method:

Add 25CC espresso into the cup, then heat the milk to 65 degrees with a steam pipe and pour it into the cup. The core of milk foam naturally forms without any mold.

If there is no professional coffee machine and no steam pipe at home. You can foam hot milk with a manual foaming machine and then pour it into coffee. Finally, cover the hollow heart-shaped mold and sprinkle with chocolate powder.

Instant coffee that is convenient but not delicious.

Instant coffee, like freshly ground coffee, has to be ground and boiled, but this process is put in the factory. Coffee smells best when it is ground into powder and boiled in water. Freshly ground coffee can make you really taste strong coffee.

The boiled coffee water is sprayed with a high-speed nozzle, just like a sprayer, and then the coffee mist is immediately dried at high temperature, leaving granular coffee crystals after removing water. That is to say, we can directly soak in water without coffee residue, but the high temperature takes away almost all the aromatic oil while removing water.

Although it tastes like coffee when drinking, it has lost the rich aromatic oil in coffee. Because of the long storage time, workers will add preservatives during cooking and atomization. And because the fragrance runs almost, additives such as creamer and essence will be added. These additives can't be digested, absorbed and deposited in the human body, causing harm to the human central nervous system and accelerating the aging of human cells.

In addition, because of the cost, of course, Robusta coffee with poor quality and high yield is chosen for instant coffee, and its producing areas are mostly in Viet Nam, China, Hainan and some countries in Africa. In addition, broken beans, bad beans and stunted varieties are directly baked and ground without screening. Because most of the essence of fragrance is lost, even the best beans don't make much sense.

It is recommended to use quick-frozen drying technology to produce instant coffee. )

Swiss Gold Swiss Gold Import Coffee Brewer

Made in Switzerland, Swiss gold Swiss gold simple coffee brewing bag. It is said that the high-density filter technology used is difficult; 23K gold plating (purity 95%) will not change color in its lifetime if it is well preserved.

The principle, structure and usage of a simple coffee brewer are very similar to those of traditional filtered coffee. Coffee powder is placed on the filter screen, and coffee drops out by the gravity of hot water.

After practical use, the characteristics of Swiss gold coffee filter are as follows:

Quality: Swissgold Filter adopts 23K gold-plated high-density filter screen, which will not absorb coffee grease and gum that brings coffee flavor like filter paper and filter cloth, nor will it react with fruit acid to affect the original taste;

Functions: coffee, tea, hot drinks, ice drops, etc. Can be applied to Swissgold filter; ;

Convenience: Swissgold is easy to use, clean and carry, and can be brewed with hot water at any time;

Economy: no alcohol gas, no filter paper and no electricity;

Environmental protection: protecting natural resources and not wasting wood and other resources;

Safety: Swissgold does not use filter paper, no residual glue, no plant protectant, and there is no concern about bleaching agent causing cancer.

When using the Swiss gold simple coffee brewer, put the preheated coffee cup under the filter screen and put the slightly coarse coffee powder in (the filter screen is very thin); Cover the inner sleeve, pour in hot water and cover. This is what a cup of pure coffee filtered with gold does. Personally, I think it is very suitable for beginners as an introduction to brewing coffee.

The science of coffee

Drinking coffee in the morning really helps to clear your head and be energetic, but you must eat breakfast before drinking, otherwise it will easily have a negative impact on gastrointestinal function. Friends with a bad stomach had better add some milk to drink coffee, so as to reduce the stimulation to the stomach and reduce the consumption of calcium. However, both milk and sugar are high in calories, so they must be taken in moderation to avoid getting fat. It is better for the stomach than drinking pure coffee on an empty stomach, but it is not enough to drink milk before drinking coffee for the sake of gastrointestinal health. Basically, doctors advise not to "eat too much" food, such as spicy, hard, cold and indigestible food and things that others advise not to eat. Because quite a few people have stomachaches, it is really difficult to "abstain from food" and it will last for a long time.

Caffeine is the main component of coffee. Moderate drinking can stimulate, refresh and strengthen the stomach, but improper drinking will be harmful to health. Scientifically speaking, it is best to drink coffee between meals. Don't drink coffee after meals or during meals, so as not to affect the absorption of nutrients such as minerals in food by the gastrointestinal tract. It is advisable to drink a cup of coffee at a time, with moderate concentration, not excessive. Friends who have no long-term drinking habits should drink no more than 3 cups a day. More than 3 cups will have a certain impact on the body.

skill

It is particularly important to note that when taking antibiotics and drugs for treating gastric ulcer, you must not drink coffee at the same time to avoid irritating the stomach.

Drinking coffee won't make your skin black.

So far, there is no research result showing that melanin in coffee is absolutely related to "melanin" in skin. On the contrary, caffeine can accelerate metabolism, promote digestion, improve constipation, accelerate the discharge of waste keratin, and dilute dark circles caused by poor circulation. Judging from these functions, it can also help alleviate the rough and dull skin.

Speaking of caffeine, it can speed up metabolism. It is said that coffee can accelerate the burning of heat, eliminate subcutaneous fat and restore skin firmness. Basically, the theory is correct, but the burning of calories does not make subcutaneous fat or weight lose much, and if sugar and creamer are added to coffee, it is even more inconsistent with the principle of losing weight in terms of calories. In addition, it is antioxidant. Drinking coffee regularly can keep skin cells full of vitality and prevent cell oxidation, which plays an important role in resisting skin aging.

Finally, the reason why your skin turns black is that you may often stay up late and refresh yourself with coffee, but it is not coffee that makes you black. You know, lack of sleep is an important killer of beauty. Pay more attention to rest In addition, although drinking coffee will not change skin color, but often drinking coffee without gargling will make teeth yellow.

Drinking coffee can always keep your mouth fresh.

Experts accidentally discovered this magical effect of coffee in the experiment. In the past, people usually thought that drinking coffee would give you bad breath. In fact, when coffee and milk are mixed, it will dehydrate the inside of the mouth and ferment to produce smelly substances. The research team chose two kinds of Arabica coffee and put them in glass test tubes filled with saliva. At first, they hoped that this experiment would prove that when coffee is mixed with saliva, it will produce unpleasant gas.

The experimental results were unexpected. Researchers have found that coffee can prevent the generation of "odor", and in some experiments, coffee can reduce the generation of "odor" by 90%. The researchers said: "We predicted that coffee would cause bad breath, but in fact, in this magical brewing process, some ingredients in coffee were found to inhibit bad breath."

Scientists believe that bad breath is inevitable, and even the healthiest body will have bad breath when it wakes up in the morning. The tongue, alveoli and other parts of the oral cavity are the "paradise" of dental plaque. This kind of bacteria can produce volatile sulfur compounds, which make the mouth smell bad. If you eat strong food such as onion and garlic, bad breath will last for a long time, because the blood will absorb these food ingredients and then enter the lungs to exhale.

The researchers plan to isolate the magic substance that inhibits bad breath in coffee, thinking that it can inhibit the formation of dental plaque and block the occurrence of bad breath from the source. It may replace mint, which can only cover breath, and become the basic component of a new generation of mouthwash, breath freshener and chewing gum. Traditional mouthwash and chewing gum can only cover for a short time and cannot completely eliminate bad breath.

Have a cup of coffee before exercise-coffee helps endurance.

Caffeine is a stimulant banned by the International Olympic Committee. The International Olympic Committee (IOC) stipulates that when the caffeine concentration in urine exceeds 1.2 μ g/ml, it is considered illegal. Recently, tests conducted by Australian laboratories on some track and field athletes who consume a small amount of caffeine have confirmed the scientific nature of this regulation, and they can bear 30% more training time than athletes who have never drunk coffee. The grade is also 36% higher than usual.

The preferred energy source of human body during exercise is usually carbohydrates stored in the liver in the form of glycogen. It's just that the carbohydrate reserve is exhausted, and it usually takes more than 60 minutes of continuous aerobic exercise. Fat can become an energy source through metabolism, so as to achieve the purpose of losing weight. However, researchers at the Australian Institute of Physical Education in Canberra found that caffeine contains substances that can make muscles consume fat directly during exercise, rather than ordinary carbohydrates.

Scientists who study sports performance have found that caffeine can promote fat metabolism. They found that cyclists who drank mild cola or coffee in the race rode faster and farther than those who drank water. Sports nutritionists point out that the results of this study may be very important for everyone who exercises regularly. She said: "After a cup of coffee or coke is absorbed by the human body, it can quickly promote the dissolution of fat into the blood, so that the human body can use fat as the main energy source before converting the limited carbohydrate reserves into energy."

Talking about low-calorie coffee-coffee that can be drunk at night

The caffeine content of ordinary coffee products is 1%-5%, and the caffeine content of low-alcohol coffee products is less than 0. 1%. The baking method of decaffeinated coffee is the same as that of ordinary coffee, but it requires a special decaffeinated process. At present, there are two mature methods to extract caffeine.

Swiss water treatment method is a low-cause treatment method that does not use any chemical solvent at all. The impact on the environment and human health is the lowest. In addition, this treatment method has a special flavor-charging water production procedure, which is the biggest difference from the chemical solvent treatment method. According to its theory, the flavor loss of low-quality coffee beans made by Swiss water treatment method is very low. Although we know more or less, it still affects the aroma and viscosity. However, in the long run, this treatment is the best demonstration of environmental protection.

In addition, there is a special low-cause treatment method, which is supercritical carbon dioxide extraction of caffeine. Theoretically, this method should keep the taste better than all other low pathogenic treatments. It is understood that before extracting caffeine, the pores on the surface of raw beans must be opened by using high temperature and high pressure steam environment in order to bring caffeine out smoothly. So it seems that there is also the possibility of flavor loss, but you won't know until you drink it. At present, it is difficult to see the trace of treating coffee beans with carbon dioxide supercritical low factor. Recently, I heard that companies with this technology patent began to expand abroad, and the chances of seeing this low-factor bean will increase greatly in the future, which is worth looking forward to.

In addition, Brazilian researchers recently found that among the 3,000 Ethiopian coffee trees they cultivated, the caffeine content of coffee beans produced by three plants was only one fifteenth of that of ordinary varieties. Researcher Masafila said that this is the first discovery. However, the growth rate of this coffee tree is about 65,438+00 years, even longer than the common variety slow three. Researchers hope to cross it with common varieties to improve its growth rate. If successful, it is expected that pure natural low-calorie coffee will be born.

The wonderful use of coffee grounds in life

More and more people are obsessed with the aroma of their own coffee. Can you just throw away the remaining coffee grounds after cooking? Teach you a few tricks to use skillfully.

fertilizer

Because coffee grounds contain nutrients needed for plant growth, as long as the cold coffee grounds are poured on the potted cultivation soil, it can not only play the role of fertilizer, but also have no odor. Insect control has always been the biggest headache for people who like to grow vegetables. If you sprinkle coffee grounds on the soil, you can prevent insects, but be careful not to sprinkle them on the roots.

Deodorization

Coffee grounds have the ability to absorb odor. Coffee grounds can be put in beautiful containers and put in the toilet, which can achieve the effect of deodorization and taste improvement. Sewing coffee grounds in a cloth bag and stuffing them into a shoe cabinet can not only retain fragrance, but also dehumidify. If put in shoes, the deodorizing effect is more obvious. Putting coffee grounds in the refrigerator can absorb odor, thus avoiding food odor. Put it in the corner of the room to absorb the odor and prevent the invasion of insects and ants. Coffee grounds can be poured into the kitchen sink to remove the dirt and smell in the sink. Putting a layer of coffee grounds in an ashtray, especially in a car, can remove the smell of smoke and help put out cigarette butts. In addition, the pot smells of oil after being used for a long time. If you fry wet coffee grounds in a pot until they are dry, you can get rid of the peculiar smell and greasy smell in the pot.

Remove moisture

Coffee grounds, like activated carbon, have many small holes that can absorb water. Therefore, the sun-dried coffee grounds can be used as desiccants and put into bookcases and wardrobes to prevent clothes and books from getting damp and moldy. If you need it urgently, you can put it in the microwave oven or oven to dry it.

Cleaning assistant

Usually, after cutting onions, garlic, cleaning fish, shrimps and crabs or eating seafood, coffee grounds can also be used to remove the fishy smell on your hands. Wrap coffee grounds with gauze, wipe the cover or range hood to remove oil stains. After drying coffee grounds, put them into stockings to polish the wooden floor, which can achieve the effect of waxing. There is proper oil in the coffee grounds. You can also wrap the coffee grounds with old stockings and sew a layer of cloth on the outside as a pin, which can prevent the needles from rusting and make it more convenient to sew clothes. There are copper products at home (the appearance is not treated, such as painting, electroplating, etc. ). Coffee grounds can be wrapped in cloth, and leaked coffee oil can be used to wipe and maintain copper products.

Firming and beautifying skin

Mix a quarter of hot coffee grounds with a tablespoon of olive oil. Stand on an old towel or newspaper and spread the mixture on the fat accumulation. Wrap the application in plastic film and wait for a few minutes. Tearing off the plastic film, brushing off the loose coffee grounds, and washing with warm water can reduce weight, tighten the skin, make the skin smooth, and achieve the effect of slimming and beautifying by decomposing fat.

refreshing

Using coffee grounds as pillow filler can soothe nerves and improve sleep quality.

Cooking delicious food

As far as cooking is concerned, use leftover coffee or fresh coffee grounds instead of used coffee grounds. The coffee left at the bottom of the pot can be used as a tenderizer to marinate steak, which can make a good taste. You can also add fresh coffee grounds to chocolate cakes and nut chocolate cakes, which will be more delicious.

Coffee and sleep-caffeine content has nothing to do with shade.

"Let's have a cup of coffee tonight!" Many people will turn pale when they hear such an invitation. The terrible memory of lying awake in bed for a long time after drinking coffee makes us stay away from caffeine. In fact, not all coffee will affect sleep.

Generally speaking, coffee has a strong flavor, which refers to the aroma of coffee, because the aroma of coffee comes from the composition of coffee beans rather than the amount of caffeine. Coffee bean is a fruit containing vegetable oil, and the volatilization of oil is the main reason for the overall aroma of coffee, so it is not directly proportional to the caffeine content. Many people think that espresso is high in caffeine. In fact, the amount of espresso is small and the brewing time is short, but the caffeine is lower than that of ordinary coffee.

Through research, we know that if coffee beans are soaked in water for a longer time during conditioning and brewing, the more coffee extracted from coffee powder, and the higher the caffeine content. For example, espresso is brewed for only 20 seconds, and the caffeine content is naturally low; However, coffee brewed for a short time has less caffeine than coffee brewed for a long time. Coffee brewed at low temperature also has less caffeine than coffee brewed at high temperature.

Tips: We usually think that black coffee has more caffeine than instant coffee, but in fact, instant coffee is mostly made of Robusta beans with higher caffeine content, considering the purpose of refreshing consumers. So the caffeine content of instant coffee is much higher than other coffees.

Coffee partners are not healthy partners-creamer is not milk.

Adding creamer to coffee and then slowly stirring it has almost become a classic plot of tasting coffee in our minds. After the melamine incident, in fact, coffee partners or creamers are no longer our traditional milk. So we don't have to worry about being hurt by melamine when adding it.

At present, the main ingredient of the familiar coffee companion is non-dairy creamer. Non-dairy creamer, the general name of vegetable oil powder, has many kinds, different functions and wide uses. Its production history can be traced back to 1950s, and it has been widely used in baking food ingredients, cold food ingredients, candy ingredients and solid beverage ingredients.

The main function of using non-dairy creamer as a coffee companion in coffee is to improve the taste and give the product a "milky feeling". What is this? Ingredients: The first ingredient is "glucose syrup", which is a slightly sweet mixture produced by starch hydrolysis and can thicken the solution. The second component is hydrogenated vegetable oil, which is a semi-solid oil formed by artificial catalytic hydrogenation of soybean oil or rapeseed oil. The third ingredient is sodium caseinate, followed by three food additives: stabilizer, emulsifier and anti-caking agent.

After artificial catalytic hydrogenation, most of the natural unsaturated fatty acids in vegetable oil become saturated fatty acids, and the unsaturated fatty acids contained in them may lose their natural cis-structure and produce unnatural "trans fatty acids".

Nutritionists believe that trans fatty acids are more dangerous than saturated fatty acids, because saturated fatty acids will only increase blood lipids, but will not reduce beneficial HDL cholesterol. Some recent studies show that trans fatty acids may also increase the incidence of breast cancer and diabetes, and may affect the growth and development of children and the health of the nervous system. So when we drink coffee, it is better to add less creamer and partner.

Tips:

The popular bubble tea is also made of hydrogenated vegetable oil, which contains a lot of trans fatty acids. Long-term drinking will have a negative impact on health.
