Instant coffee is a kind of coffee products, which can not be regarded as coffee in the real sense, which is a common view in the traditional coffee industry. Instant coffee is a synthetic product of industrialization, and it is a good substitute for coffee in some specific environments, such as long-distance travel on trains and airplanes, rather than coffee in the original sense. instant coffee in the synthesis process of coffee original nutrition and health ingredients are destroyed and disappear, although it also has the taste of coffee. However, it has lost the rich nutrients in coffee and the efficacy of health care, as well as the thick cultural taste and atmosphere. In addition, the preservatives, pigments, sweeteners and other additives contained in instant coffee cannot be digested and absorbed in the human body and continue to be deposited, so "instant coffee" should not be drunk frequently.

Instant coffee is a dry coffee extract obtained by evaporating the water in the coffee extract. Instant coffee can quickly dissolve in hot water, and it takes up less space and volume in the process of storage and transportation, so it is more durable to store. It is different from the more complicated traditional way of brewing coffee, so it has been widely popular.

Instant Coffee

In order to deal with the surplus of coffee beans, the Brazilian government and Nestle developed a more advanced spray drying method for the manufacture of instant coffee in 1938. The specific method is to use hot steam to vaporize the water in the coffee beans, leaving the dry coffee extract. Instant coffee can quickly dissolve in hot water, and it takes up less space and volume in the process of storage and transportation, so it is more resistant to storage, so it is popular in the mass market.

Instant coffee was first used in the battlefield of World War II, when allied soldiers used instant coffee as a daily drink, which improved efficiency to a certain extent.

However, because inferior coffee beans are often used in industrial production, and other harmful residues may be left in the production process, it is not recognized by the traditional coffee industry in many cases. In addition, the roasting degree of instant coffee to coffee beans is often not enough, stay in a relatively primary stage, can not fully reflect the aroma of coffee beans.

The harm of instant coffee

Because of the cost, the broken beans, bad beans and poorly developed varieties are often baked and ground directly without screening. Anyway, it is only the extraction of caffeine, and the lack of aroma can also be reconciled by all kinds of flavors and additives, which results in the poor quality of coffee beans that make instant coffee.

Instant coffee is mainly composed of glucose syrup, hydrogenated vegetable oil and various food additives, such as emulsifier, water retention agent, antagonist and so on. There are two main health problems worthy of attention: one is food additives. Even if these large brands of products can reasonably use all kinds of food additives in accordance with the relevant standards, complex and diverse food additives are still a hidden danger of food safety. Second, hydrogenated vegetable oil, hydrogenated vegetable oil contains "trans fatty acids", and excessive trans fatty acids have a clear harm to cardio-cerebrovascular system.

Although there is a little coffee taste when drinking instant coffee, it has lost the rich aromatic oil in the coffee. What's more, in order to keep it for a long time, workers will add preservatives in the process of cooking and atomization, and because the fragrance is almost gone, additives such as milk essence and essence will also be added. These additives can not be digested and absorbed in the human body and continue to deposit, causing harm to the central nervous system of the human body and accelerating the aging of human cells. Therefore, for those who really love life and coffee, instant coffee is not sweet and harmful to health.
