The benefits of black coffee
What are the advantages of black coffee? Researchers in the Affiliated Hospital of osaka city university found that drinking more than one cup of freshly brewed coffee every day can improve the liver function of patients with chronic hepatitis C, and the research results were published in the American academic journal PLoS One published on 20 13 1 1.
376 patients aged 20-80 with chronic hepatitis C in osaka city university Affiliated Hospital were investigated for the relationship between the change of ALT enzyme quantity (ALT enzyme quantity will increase with the damage of liver cells, which is usually used as an index of liver function) and the frequency of drinking coffee. The results showed that the ALT enzyme values of patients who drank more than one cup of freshly brewed coffee every day in 1 year were mostly within the normal range compared with patients who did not drink. Moreover, the greater the amount of coffee, the more significant the liver protection effect. The researchers also found that drinking canned coffee drinks, instant coffee and not drinking coffee had no corresponding liver protection effect.
manufacturing method
There are three ways to make black coffee, so there are three different types of coffee pots: traditional filter, siphon and electric. Traditional filters are the most primitive and simple tools. The coffee pot consists of a funnel, a filter paper and the container below, but it requires high manual technology. If you grasp it properly, you can cook the best coffee with mellow taste. This kind of pot is very cheap, you can buy it for more than ten yuan. The brewed coffee pot is suitable for people who drink coffee, with stable hand feel and sharp taste. It is important to pay attention to whether it is a three-hole or a one-hole coffee set. The dripping speed of three holes is faster, the extraction time is shorter, the coffee is lighter, and the opposite is true of one hole. Siphon uses the siphon principle. Under the burning of alcohol, when the water temperature in the lower container reaches 92℃, the water flow is sucked into the upper container together with the coffee powder. After soaking and stirring, the coffee returns to its original way. Due to the addition of a stirring process, this method of black coffee has a strong flavor, but it is relatively simple because it does not require manual skills. The market price of this coffee pot is mostly one or two hundred yuan. The price of electric coffee pot is comparable to that of siphon coffee pot. It uses electricity to boil water and then soaks it. This is the easiest way to make black coffee, but because it is made with boiling water, it tastes slightly inferior. Comparatively speaking, the electric coffee pot is more suitable for young people with petty bourgeoisie who are afraid of trouble. The price of common electric coffee pots ranges from one hundred yuan to three or five hundred yuan. Although the traditional filter type is the simplest, it is the coffee pot that can best cook the original flavor of coffee; In the production process, it is necessary to accurately grasp the water temperature, water flow size and trajectory. Uniform water flow and circular trajectory can make coffee taste natural, so it is very important to choose and control the kettle when pouring water with both hands. When the water comes into contact with coffee, it should be as round as possible, from outside to inside and from inside to outside, so that coffee can fully contact with the water; At the same time, the water temperature of 92℃ can make the aroma, alcoholicity, sweetness, acidity and bitterness of coffee uniform and rich. If the water temperature is too high, it will burn the coffee and make the taste sour and astringent. On the low side, it is difficult to brew the aroma of coffee.
Beverage variety
Aroma: Black coffee emphasizes the aroma of coffee itself. Aroma is the life of coffee quality, which can best express the making process and baking technology of coffee. The climate, variety, refining treatment, harvesting, storage and baking technology of the consuming country are all conditions that determine the aroma of coffee beans. Bitterness is the basic taste of black coffee, and its strength and texture are different. Raw beans only contain a very small amount of bitter ingredients, and then the most symbolic bitter taste of coffee is produced by caramelization and carbonization of sugar, starch and fiber caused by baking. Black coffee also has a sour taste. Proper heating will produce moderate acidity, which will make coffee taste better and make people feel deeper. The sweetness of black coffee is closely related to the bitterness, so refreshing and superior black coffee tastes sweet.
Raw material: Coffee beans are the raw material of black coffee. There are hundreds of kinds of coffee beans, and the price varies according to the variety, origin and grade. We are familiar with Yunnan coffee, Blue Mountain, Mantening, Huju, Brazil and charcoal, which can be bought in many supermarkets, and most of them are baked beans. Due to different producing areas, the characteristics of coffee beans are different, some of which are darker in color, higher in baking degree and stronger in taste; Some are lighter in color and slightly lighter in taste. Experts choose coffee, mostly by grabbing a handful of coffee beans to see whether the color of each bean is consistent and whether the particle size and shape are similar, so as to avoid buying inferior products disguised as mixed beans. In addition, if the baked beans are oily, it means that they have gone bad, not only the mellow degree is reduced, but also the astringency and sour taste will appear.
