"Instant coffee" is not generally accepted coffee in the traditional coffee industry. Instant coffee is an industrial synthetic product. In some specific situations, such as long-distance travel, it is a good coffee substitute on trains and planes, rather than coffee in the original sense, because traditional coffee is very particular about grinding, boiling and filtering coffee beans, as well as the selection of utensils and different blending techniques. In the process of synthesis, the original nutritional and health components of instant coffee were destroyed and disappeared. Although it tastes like coffee when you drink it, it loses its rich nutrition and health care functions, as well as its heavy cultural taste and atmosphere. In addition, preservatives, pigments, sweeteners and other additives contained in instant coffee can not be digested and absorbed in the human body, and are constantly deposited, causing harm to the human central nervous system and accelerating the aging of human cells. Therefore, natural health is the most important.
The monitoring results of China Food Contamination Monitoring Network show that the acrylamide content in fried potatoes, barley tea, instant coffee, corn tea, fried grain food and baked grain food is high, while animal experiments show that acrylamide is a known human carcinogen.
According to the sampling data of the US Food and Drug Administration, the acrylamide content of instant coffee powder is as high as 458ppb, while that of freshly ground coffee is about 10ppb. Instant coffee is made of coffee powder. It produces soluble coffee powder by preparing espresso and then removing water from it. In the process of concentrating and drying instant coffee, high temperature treatment will produce more acrylamide.
The coffee mentioned in the following article is freshly ground coffee beans!
