The difference between instant coffee and hanging-ear coffee efficacy, function and side effect of instant coffee

What's the difference between instant coffee and ear coffee?

Most people's understanding of coffee is from the beginning of instant coffee, but the ground coffee and ear-hanging coffee know too little, instant coffee is only used in the case of temporary replacement of coffee, as long as there are conditions, or to go to the cafe to drink coffee.

Instant coffee is produced by grinding roasted coffee beans and extracting the active ingredients in coffee into water at a certain temperature and pressure, and then drying them. It is concentrated in vacuum to facilitate the drying process. Spray drying method is widely used at present, but this method is easy to volatilize the aroma substances in coffee, which is the main reason why instant coffee is not rich in the aroma of fried coffee.

Ear coffee is made of ground coffee powder placed in a bag made of non-woven fabric packaging. When drinking, you need to hang it on the mouth of the cup and brew it with boiling water. Coffee powder can be thrown away directly, sugar and milk need to add their own. The aroma of coffee made by ear-hanging bag is difficult to compare with instant coffee; with a good ear-hanging bag, as long as the water temperature and flow are controlled well, it can make the effect comparable to hand-brewed coffee.

Instant coffee is made by drying the active ingredients extracted from fried coffee beans, which will lead to the loss of aroma in the process, making the flavor and taste of the finished product far less than that of fresh grinding.

The quality of coffee beans in instant coffee is also a big problem that cannot be guaranteed. The proportion of broken beans and bad beans cannot be estimated. In the eyes of businessmen who maximize profits, inferior production can increase profit margins.

Coffee beans are roasted and ground directly without screening, and additives such as essence are added after caffeine is extracted.

The main component of instant coffee is plant fat powder, while the main components of plant fat powder are glucose syrup and hydrogenated vegetable oil (containing a lot of trans fatty acids, excessive intake will affect cardiovascular and cerebrovascular health).

Ear coffee: coffee beans are ground and placed in a brewing bag. Usually the outer bag is packed with aluminum foil or kraft paper to ensure that the ground coffee powder will not lose its flavor.

When in use, only need to open the ear bag, use the two sides to hang the ear fixed on the cup, and then pour hot water, wait for coffee drops to a certain amount can drink.

There is still a certain difference between the taste of coffee extracted by ear bags and professional machines. Because ear bags are a drip type of coffee. But the coffee powder inside does not contain any additives, brewing out of all pure black coffee.

Direct contrast between ear hanging and instant:

1. fragrance

The ear-hanging coffee begins to emit a strong aroma when it is brewed. If you are in a small tea room, the whole tea room will be filled with the aroma of coffee and stay for a long time.

Instant coffee aroma short-lived, also in the small space of the tea room, only close to your side of the talent will smell the faint coffee aroma.

2. Taste

Because it is black coffee, the taste is bitter but not astringent. The mellow taste of coffee rolls on the tip of the tongue straight to the brain. Whether it is hot coffee, cold coffee or iced coffee, the original aroma of coffee will not be scattered, but the taste difference will be large due to different temperatures.

Because instant coffee is not made of pure coffee, although it is smoother in the mouth, it will leave a slight sticky and sour feeling in the mouth, rather than the sour taste felt in the coffee liquid. And the aroma knows the nose and mouth, after the coffee cools down, the taste is worse, not only there is no coffee aroma at all, even the mellow taste of the coffee has almost disappeared.

3. heat

Black coffee is a good weight loss product. A cup of 200ml black coffee has only 2 calories, while a cup of instant coffee varies from 42 calories to 130 calories. Ear coffee is black coffee! Ears have a fraction of the calories of instant coffee.
