3. Aluminum ion deposition in bones can lead to osteoporosis, fracture and joint pain.

4, aluminum ion deposition in the skin, will make the skin elasticity lower, wrinkles increase.

Taste type and taste

In the aspect of the preparation of hot and sour powder, the seasoning techniques of Chongqing Noodles are used for reference, for example, chili pepper sea pepper is used to obtain the basic orientation of flavor. However, the inherent physical characteristics of sweet potato vermicelli are that they don't smoke spices. In this regard, Chongqing people who are persistent in taste and like to study have created a unique taste of sweet potato vermicelli which is rooted in the characteristics of Chongqing, but has a distinct personality.

Because vermicelli should not absorb moisture and seasoning, the taste of hot and sour powder seasoning is heavier than that of ordinary local soup powder. For example, ginger and garlic powder is not added to the soup, but added directly, which makes the use of spicy and hemp taste more violent and more choking.

More importantly, the use of vinegar is a pioneering work. The volatile vinegar can stimulate the smell of other spices to form a comprehensive aroma, so that a bowl of hot and sour powder can be smelled from a distance. Authentic Chongqing hot and sour powder does not use Shanxi vinegar or balsamic vinegar. Baoning vinegar with a history of hundreds of years, brewed in winter water in the middle reaches of Jialing River, is sour and fragrant, slightly sweet, and the smell of acetic acid is subtle and not pungent. It is an authentic match for Chongqing hot and sour powder.
