1, by composition
The ingredients of self-heating hot pot are different, some are mainly meat, and some are mainly vegetables:
(1) Meat dishes
For people who are unhappy without meat, meat and vegetable hot pot is perfect. It is filled with all kinds of delicious meat, including beef, mutton or chicken. These meats are high in protein and low in fat, so they won't be greasy. Moreover, the meat is chewy and can supplement the nutrients needed by the body.

(3) the collocation of meat and vegetables
Most of the dishes in self-heating hot pot are scientifically matched, including different ingredients such as meat, vegetables and vermicelli, which pay attention to the balance of nutrition and rich taste. The ingredients of different hot pots are also slightly different, so you can choose according to your own preferences.
Step 2 divide by taste
In addition to dividing by ingredients, self-heating hot pot also has differences in taste.
(1) spicy.
When it comes to hot pot, you have to mention Sichuan. The hot pot there is different from other places. It is fried with a mixed secret recipe of various spices, in which a lot of peppers and peppers are added, making the ingredients easier to taste, spicy and refreshing, and very enjoyable.
(2) Tomato flavor
Tomato pot is also a good choice for most people who can't adapt to spicy hot pot with heavy taste. This tomato-flavored hot pot is made of high-quality tomatoes and broth. It is not only fragrant, but also suitable for cooking all kinds of ingredients, and you can also taste the soup base directly. Sweet and sour.
(3) Three umami flavors
Sanumami is also a common hot pot with a light taste, which is very suitable for people who are afraid of spicy food or fitness. These three flavors can not only reduce the probability of getting angry, but also let you taste the natural fragrance of various ingredients and enhance the flavor without affecting the original flavor.
(4) Other tastes
With the popularity of self-heating hot pot, more and more people are not satisfied with the traditional taste, but pursue unique taste. So it has curry flavor, rattan pepper flavor and many other flavors. For example, a curry-flavored hot pot can enrich the ingredients, while the taste of rattan pepper is more numb.
Second, how much is a box of self-heating hot pot?
The price influencing factors of self-heating hot pot are related to the brand, the quantity of meat and vegetables and the quantity of ingredients. Usually, the price of ordinary vegetarian food in self-heating hot pot is around 30 yuan -60 yuan, and there are some hot pots with a price of more than ten yuan, but it is not recommended to buy this kind. First, the hot pot of more than ten yuan must have a small amount of ingredients, and most of them are vegetarian dishes, so they are not full. On the other hand, it is difficult to guarantee the quality and freshness of the ingredients in the self-heating hot pot of more than ten yuan.
Third, how to choose a convenient self-heating hot pot?
1, pick the heating package
The highlight of self-heating hot pot is that it doesn't need fire, electricity or pot, and it doesn't need to prepare its own ingredients. Just add a glass of cold water and wait for more than ten minutes. No matter on an outing or on a train, you can eat steaming hot pot. The heating package plays a key role, and its principle is to release heat through the chemical heating agent in the heating package. As long as it is not in direct contact with food, it will not affect food health. Therefore, be sure to check carefully after unpacking. If the heating package is damaged and you accidentally touch the food, don't eat it. The main types of heating components are as follows:
(1) type of quicklime
Most of the chemical heating agents used in self-heating hot pot are calcium oxide, the most important of which is calcium oxide. When it comes into contact with water, it can produce hydrated lime, the scientific name is calcium hydroxide, and it will release a lot of heat in the process, which is the main heat source of heating package.
This kind of quicklime heating bag not only has a small calorific value per unit mass and a large amount of heating agent, but also the ingredients are easy to absorb water and get wet, which affects the taste. Although the heating rate is fast and the heat is large, it is easy to burn the skin and pollute the environment. It is not recommended to choose.
(2) diatomite powder mixture
There is also a mixture of diatomite powder, coke powder, sodium chloride, water and reduced iron powder, which is a typical adsorbent. Its porous structure is more conducive to the adhesion, full contact and chemical reaction of various effective components.
The heating speed of this kind of heating bag is very fast, but the disadvantage is that its heating temperature is lower than 60℃, which may cause uneven heating of ingredients, thus affecting the taste.
(3) reducing the iron powder mixture
The other is to mix reduced iron powder, activated carbon, wood powder, diatomite and Chili powder, add salt water, fully stir under the protection of nitrogen, and then package, cut and package. Its advantage is that because of the use of Chili powder, the heating effect is strong, but the heating constant temperature is only 42~55℃.
(4) Mg-Fe alloy powder
The flaky heating package made of magnesium-iron alloy powder and other components can react with the activator to generate heat, which is transferred to the food package to obtain hot food. High self-thermal efficiency, uniform heating, no pollution and convenient carrying.
5 1 Dongshibian Xiao suggested that the heating bag made of reduced iron powder mixture and magnesium-iron alloy powder should be selected as far as possible when purchasing, which can not only emit enough heat, but also avoid worrying about the environmental pollution caused by heating reaction products.
Step 2 look at the ingredients
At the same time, we should also pay attention to the nutrient composition table of self-heating hot pot and choose a healthy type. The ingredients of self-heating chafing dish usually include:
(1) protein
Protein, as an essential nutrient for human body, plays a very prominent role in meat products, which can be used as a standard to judge the quality of food to some extent. According to dietary regulations, adults need to consume about 75g of protein every day, so the higher the content of protein in hot pot, the better, and its content should not be less than 7.5g/ 100g.
(2) Fat
Fat is an essential component of human body, but good fat should be taken in moderation. Such as unsaturated fats, monounsaturated fatty acids and polyunsaturated fats, and relatively "clean" saturated fats. The fat content of a high-quality self-heating hot pot should be controlled between 20% and 25%.
(3) Carbohydrate
Carbohydrate is one of the three essential nutrients for human body, and it is also one of the main sources of our total calories in a day. Generally speaking, an adult needs to consume 300 grams of carbohydrates every day. If it exceeds the standard, it will easily lead to obesity, and if it is too small, it will also affect his health.
(4) Sodium
Among the core nutrients, sodium is the most easily overlooked. Now most people are aware of cooking with less salt, but they seldom pay attention to the salt content in packaged food. Adults should consume 2.2g sodium every day. Under the same conditions, the lower the sodium content, the healthier it will be.
(5) preservative
Different from traditional fast food, self-heating hot pot contains a large number of products processed with fresh ingredients. If it is not properly preserved, it is easy to cause bag expansion due to deterioration of ingredients. Some products are dried and packaged in vacuum without preservatives; While others are preserved with preservatives. Commonly used preservatives are potassium sorbate and sodium salt, which are internationally recognized as safe preservatives. Because it is an unsaturated fatty acid, it can also be absorbed by the body's metabolic system and quickly decomposed into carbon dioxide and water. There is no residue in the body, and the maximum dosage cannot exceed 1.0g/kg.
Suggestion: Try to choose self-heating chafing dish with high protein and no less than 7.5g/ 100g, fat content between 20% and 25%, carbohydrate content around 300g and sodium content no more than 2.2g; It is best not to contain preservatives, and the dosage should not exceed 1.0g/kg.
3, identify the quality
(1) Look at the color.
The color of self-heating hot pot can be divided into two steps: soup base and ingredients. First, you can look at the bottom of the hot pot. If it is the bottom of spicy butter pot, the color should be orange-red. After heating, it can melt evenly, and the soup base is bright and ruddy. If the color of the soup base is too bright, it probably contains additives. The same is true of ingredients. The processed vegetables should keep their original natural color. Once they are too white or too bright, bleach or additives are likely to be used.
(2) Smell
The general fragrance is determined by the taste of small hot pot. Butter is spicy and tomatoes are fragrant. The oil contained in hot pot also has a great relationship with flavor, and the oil is rich in flavor; If the amount of hot pot oil is not very large, but the taste is particularly fragrant, it means that it contains chemical components such as flavoring agents.
(3) Look at the heating speed
In the process of eating self-heating hot pot, we can also judge the quality of the product according to its heating speed. A good self-heating hot pot has fast heating speed and sufficient heat, and the ingredients inside can be cooked; And the poor quality hot pot, heating speed is slow, cooked meat is not cooked.
(4) Taste
Finally, the taste link, such as meat, should have a firm taste after cooking, be elastic when bitten in the mouth, have no starch flavor, and crisp vegetables have natural sweetness; On the other hand, if meat tastes inelastic, it is probably fake meat mixed with starch or other ingredients.
Conclusion: Good self-heating chafing dish is natural in color, neither too deep nor too light. Hot pot contains a lot of oil, which makes it rich in flavor, while a little oil makes it light in taste. There will be no odor or rancidity; The heating speed is fast, and the ingredients are evenly heated; The taste is crisp and chewy.
