Black coffee (one of the kinds of coffee drinks)

Black coffee is unembellished coffee, black coffee brings the original feeling of tasting coffee. Black coffee combines the characteristics of sweet and bitter coffee, it is primitive and rugged, profound and intriguing. However, we always know too little about black coffee, and the distance makes it even more mysterious. In fact, black coffee is by your side, fall in love with it, and you will find it.

There are three ways to make black coffee, so there are three different types of coffee pots: traditional follicle type, siphon type and electric type. The traditional follicle style is the most primitive and the simplest way to do it. The coffee pot is composed of a funnel, a piece of filter paper and a container below, but it requires high manual craftsmanship. If you handle it properly, you can make delicious coffee with a mellow taste. The price of this kind of pot is so cheap that you can buy it for more than ten yuan. The follicular coffee pot is suitable for coffee tasters with stable handle and keen taste. When buying follicular coffee utensils, pay attention to whether it is three holes or one hole, which is very important. The dripping speed of three holes is faster, the extraction time is short, the coffee is lighter, and the opposite is true for one hole. Siphon is based on the principle of siphon. Under the combustion of alcohol, when the water temperature in the lower container reaches 92 ℃, the water is sucked into the upper container with coffee powder. After soaking and stirring, the coffee is returned. Due to the addition of a mixing process, this method of black coffee has a strong flavor, but because it does not need to rely on manual technology, the practice is relatively simple. The market price of this kind of coffee pot is mostly one or two hundred yuan. The price of an electric coffee maker is comparable to that of a siphon coffee maker, which boils the water and soaks it through electricity. It is the easiest way to make black coffee, but it tastes a little worse because it is made from boiling water. In contrast, electric coffee pots are more suitable for young people who are petty bourgeoisie and afraid of trouble. The prices of common electric coffee makers range from one hundred yuan to three or five hundred yuan. Although the traditional follicle style is the simplest, it is the coffee pot that can best brew the original flavor of coffee. In the production process, it is necessary to accurately grasp the water temperature, water flow size and trajectory. A uniform flow and a round track can make the coffee taste natural, so the choice of the kettle and the control of pouring water with both hands are very important. When the water comes into contact with the coffee, it should be kept round as far as possible, from the outside to the inside, from the inside to the outside, so that the coffee is in full contact with the current. At the same time, the water temperature of 92 ℃ can make the coffee fragrant, mellow, sweet, sour, bitter uniform and strong, too high water temperature will scald the coffee, make the taste sour and astringent; low, it is difficult to brew the coffee strong.

2 the flavor of beverage variety editing

Black coffee emphasizes the aroma of coffee itself. Aroma is not only the life of coffee quality, but also the best expression of coffee production process and roasting technology. The climate of the place of production, variety, refined treatment, harvest, storage, and the appropriateness of baking technology in the consuming country are all conditions that determine the aroma of coffee beans. Bitter is the basic taste of black coffee, there is a difference between strength and texture, raw beans contain only a tiny amount of bitter ingredients, followed by baked sugar, part of starch, fiber caramelization and carbonization, to produce the most symbolic bitterness of coffee. Black coffee also has a sour taste, and proper heat to produce a moderate sour taste will make the coffee taste better and make people feel more deep. The sweetness of black coffee is closely related to the bitter taste, so the refreshing black coffee must have a sweet taste.

Raw material

Coffee beans are the raw materials of black coffee, there are hundreds of kinds, and the price varies according to the variety, origin and grade. We are familiar with Yunnan small grain coffee, Blue Mountain, Mantenin, Amber, Brazil, charcoal roast and other kinds, which can be bought in many supermarkets, most of which are roasted ripe beans. Due to different producing areas, the characteristics of coffee beans are also different, some of the color is dark, the degree of baking is higher, the taste is thicker; some are lighter in color and slightly lighter in taste. The expert candidate for coffee is to grab a handful of coffee beans to see whether the color of each bean is the same and whether the particles are similar in size and shape, so as to avoid buying shoddy products disguised as mixed beans. In addition, if the baked beans out of oil, it has gone bad, not only reduced aroma, but also astringent and sour taste.

Healthy drinking method

Caffeine is a kind of central nervous system stimulant, which can accelerate the heartbeat and sweat to promote metabolism, which is also one of the main pharmacological effects of coffee to lose weight, but if it is said that caffeine can inhibit appetite, we really do not see its mechanism. He said that there are indeed many patients in the clinic who have tried black coffee to lose weight. Some people drink more than 10 cups of coffee a day, resulting in not only stomach ulcers, but also symptoms of insomnia and anxiety. As a result, according to the Department of Health, do not consume more than 300 milligrams of caffeine a day.

Drinking black coffee to lose weight is not healthy. If you really want to use black coffee as a weight loss aid, it should not be excessive, but also should be in line with the causes of obesity. For example, slow metabolism, usually not sweating, and constipation problems, with the right amount of black coffee, in addition to boost metabolism, because caffeine can also stimulate visceral sympathetic nerves, enhance intestinal peristalsis, and sometimes promote defecation. But people who already have ulcers, insomnia or heart problems are not suitable for drinking black coffee.

The benefits of black coffee

What are the benefits of black coffee? Researchers at the affiliated Hospital of Osaka City University in Japan have found that drinking more than one cup of freshly brewed coffee a day can improve liver function in patients with chronic hepatitis C. the study was published in the December 11, 2013 issue of the American academic journal PLoS one.

The affiliated Hospital of Osaka City University investigated the relationship between the number of ALT enzymes (the number of ALT enzymes increases with the injury of hepatocytes, which is usually used as an indicator of liver function) and the frequency of coffee drinking in 376 patients with chronic hepatitis C at the age of 20 to 80 years. The results showed that most of the patients who drank more than one cup of freshly brewed coffee a day for a year maintained their ALT enzyme levels in the normal range compared with those who did not drink. And the more coffee you drink, the more effective it is to protect the liver. The researchers also found that drinking canned coffee drinks, instant coffee and decaffeinated coffee had no corresponding hepatoprotective effect. [1]

4 weight loss method editor coffee is a very good weight loss food, coffee weight loss in weight loss coffee is not only can be used to drink, coffee for weight loss there are many wonderful uses, drinking coffee to control the amount of coffee can promote fat metabolism to help lose weight fat burning, but in fact the amount of coffee per day should not exceed 10 cups (calculated by each cup of 150ml).

The amount of coffee to drink should be controlled.

Although coffee can promote fat metabolism and help you lose weight and burn fat, you should actually drink no more than 10 cups of coffee per day, calculated on the basis of each cup of 150ml. Excessive caffeine can excite the nerve center, causing insomnia, anxiety and irritability, while excessive alkaline intake can also affect gastric acid secretion, leading to gastrointestinal obstruction and even gastric mucosal damage and gastric ulcers. Therefore, do not drink too much coffee, generally speaking, 2-3 cups a day can meet the needs of the day, do not drink too much.

Coffee bean dregs are also treasures.

Many people like to drink instant coffee, which is made by refining the liquid into powder at extremely high temperatures, so its own caffeine content is not high. If the editor still thinks that he can brew coffee at home, not only the flavor is stronger and the effect of burning fat is better, but the remaining coffee bean dregs can also be wrapped in gauze to soak the bath or rub the swollen legs and fat parts. This is also a very good slimming baby. You can't throw it away at will.

Find the right time to drink coffee

Drinking coffee can help you lose weight, but you have to find the right time to make caffeine work fully. Expert research shows that when you drink coffee 40 minutes later, the concentration of fatty acids in the body's blood will rise to the highest, this is the best time to exercise to lose weight, because fatty acids promote the decomposition of fat, making exercise weight loss more effective. So the time to drink coffee can be put half an hour before exercise, the slimming effect will be greatly improved.

Find the right way to drink coffee

Not all coffee is to lose weight. The editor emphasizes black coffee, that is, coffee with a cocoa purity of more than 75%. But the taste of black coffee is so rich and bitter that many girls can't accept it. Therefore, ordinary coffee reduces the content of cocoa and adds sugars. The weight loss effect of this kind of coffee is naturally not good, and sugars can also cause weight gain. You should also pay attention to the drinking method after choosing black coffee. Condensed milk, square sugar and granulated sugar must not be added. Sugars will affect fat decomposition and increase calories. If you can't stand the bitter taste, you can add a little sugar-free milk to taste, but not too much.

The way you bake is important.

The flavor of coffee is mainly determined by the baking time and temperature of coffee beans, and these two factors also determine the caffeine content in the final coffee. Generally speaking, the temperature at which coffee beans are roasted is 178 degrees, because this temperature completely exudes the flavor of coffee beans, but this is also the temperature at which caffeine is decomposed. So the deep-baked coffee has a good flavor, but actually the caffeine content is very low, so if you want to lose weight, you should choose light-roasted black coffee.

There is a difference between hot and cold drinking

With the development of coffee making technology, from strong hot coffee to adding carbonated drinks, ice cream and milk, and then adjusting the flavor in a chilled way, these compound versions of coffee are favored by many young girls. But in fact, caffeine works best when it is hot, so you will feel feverish half an hour after drinking hot coffee, which is the result of caffeine promoting blood circulation. By contrast, the efficacy of iced coffee is much weaker, not even 1/3 of that of hot coffee.
