Matters needing attention in drinking instant coffee

Excessive use of instant coffee can have some effects on the body. Instant coffee is a chemical product, and some of its original functions have been lost in the production process. in addition, the pigments and preservatives added to instant coffee are not good for the body. In addition, a substance called acrylamide is produced in the process of coffee production, which is a known carcinogen, so as long as you have time, you should try to drink freshly ground coffee in a coffee shop.

1. Flavors will be used to make up for the lost aroma in the production of instant coffee.

Instant coffee is produced by drying after extracting active ingredients from roasted coffee beans. In this process, some aromatic substances will inevitably be lost, so that the flavor and taste of the finished product is not as rich and pure as that of directly roasted coffee. Generally speaking, the production process of instant coffee can be summarized as pretreatment, roasting, grinding, extraction, concentration and drying, in which pretreatment is a process of removing impurities.

In the process of culture and frying, coffee bean substances will undergo complex physical and chemical reactions to form unique coffee aroma substances. After grinding, the active ingredients in coffee can be extracted into water at a certain temperature and pressure. Instant coffee powder can be formed by vacuum concentration and drying. At present, more spray drying methods are used in this step, but because the aromatic substances of coffee are very sensitive to heat and are easily volatilized at higher drying temperatures (there are certain volatilization in the process of extraction and concentration), the aroma of instant coffee is not as strong as roasted coffee. In order to make up for the aroma of coffee, manufacturers will adopt the practice of adding edible flavor. Therefore, we must not excessive intake of instant coffee, otherwise, will also eat a lot of flavor.

two。 The varieties of coffee beans that produce instant coffee are not high.

Due to the cost, instant coffee is often chosen by Robusta, which is mainly produced in Vietnam, Hainan and Yunnan in China, and some countries in Africa. At the same time, the screening process of coffee beans is not always very rigorous. In addition, acrylamide, which is not very healthy, may appear in the production process of instant coffee (which remains to be proved). Freshly ground coffee made from boutique coffee beans is better than instant coffee.
