Advantages and disadvantages of instant coffee instant coffee nutrition eliminates fatigue coffee bean flavor

Instant coffee is a dried coffee extract obtained by evaporating the water in the coffee extract. Instant coffee dissolves quickly in hot water, takes up less space and volume during storage, and is more resistant to storage.

As a result, instant coffee gradually gained widespread popularity. So, what are the benefits of instant coffee and precautions? Let's take a look at it with yjbys!

Benefits of drinking instant coffee

1. Coffee contains certain nutrients.

Second, drink instant coffee precautions

Excessive consumption of instant coffee can have some effects on the body. Instant coffee belongs to chemical products, and some of the original functions of coffee are lost in the production process. In addition, the pigments and preservatives added in instant coffee are not good for the body. In addition, coffee production process produced a substance called acrylamide, this substance is a known carcinogen, so as long as there is time, we still try to go to the cafe to drink freshly ground coffee, that kind of quality is better.

1. In instant coffee production, essence is used to compensate for lost aroma

Instant coffee is produced by extracting effective ingredients from fried coffee beans and drying them. In this process, some aromatic substances will inevitably be lost and the flavor and taste of the finished product will not be as rich and pure as that of directly fried coffee. In general, the production process of instant coffee can be attributed to the steps of pretreatment, roasting, grinding, extraction, concentration and drying, among which pretreatment is the process of removing impurities.

In the process of roasting, coffee beans will undergo complex physical and chemical reactions to form unique coffee aroma substances. After grinding at a certain temperature and pressure, the active ingredients in coffee can be extracted into water. Instant coffee powder is shaped by vacuum concentration and drying. At present, this step uses more spray drying method, but because the aroma of coffee is very heat-sensitive, it is easy to volatilize at higher drying temperatures (there is a certain volatility in the extraction and concentration process), so the aroma of instant coffee is not as strong as fried coffee. In order to compensate for the aroma of coffee, manufacturers will adopt the practice of adding edible essence. Therefore, we must not excessive intake of instant coffee, otherwise, will also intake a lot of essence.

2. The coffee beans used to produce instant coffee are not of high quality.

Due to the cost relationship, instant coffee is often selected Robusta species, its origin is mostly in Vietnam, Hainan, Yunnan, China, and some countries in Africa, at the same time, the screening process of coffee beans is not always very rigorous, coupled with instant coffee production process may also appear and not too healthy acrylamide (still to be proved), therefore, with fine coffee beans made of freshly ground coffee or instant coffee is better.
