What's the difference between hanging-ear coffee and instant coffee? Will hanging-ear coffee brew affect your health for many times?

Information Times News (Reporter Zhou Weilong correspondent Tian Naiwei) Coffee is a favorite drink for white-collar workers. Miss Chen, a white-collar worker, said that she used to drink instant coffee, but recently she tried to drink hanging-ear coffee under the recommendation of a friend. "hanging ears are more expensive, so I always soak water twice, but I hear friends say that soaking for many times will have impurities, leading to calcium deficiency. I don't know if it's true."

The reporter learned that instant coffee is a deep-processed coffee drink that can be directly dissolved in water, which contains some chemical additives and preservatives. On the other hand, hanging-ear coffee is sealed with ground coffee powder in a pocket made of non-woven fabric. Because of its high technology and quality, hanging-ear coffee of the same specification is more expensive than instant coffee.

In response to Miss Chen's question, Zeng Jing, director of the Nutrition Department of the Armed Police Hospital, said that ordinary hanging-ear coffee is recommended to be brewed once. The extraction of coffee is through the first hot water flowing through the coffee particles, from which the nutrients are dissolved into the formed coffee liquid, which will extract most of the nutrients from the coffee particles and release the aroma components; if you brew for the second time, although there is a very small amount of residual nutrients can be released, but there will be more impurities and smells into the coffee liquid, becoming a cup of shoddy coffee liquid. "of course, it's more about taste, and it doesn't have any impact on your health." Zeng Jing said that if it is a higher-quality coffee bag, the taste does not change much after brewing, you can also taste more.
