For a long time, the white and plump steamed buns and steamed buns have been everyone's first choice when shopping. But you know what?Some steamed buns or buns with better colors and better appearance, especially full size, may be made with "baking powder containing aluminum". Eating too many of these steamed buns and steamed buns will endanger health and even cause irreversible damage to liver and kidney function.
What is "baking powder with aluminum?".
At present, there are two types of common baking powder in the market, one is aluminum-free baking powder without aluminum, and the other is baking powder with aluminum, both of which belong to chemical leavening agents.
Among them, the main components of aluminum-free baking powder are ammonia bicarbonate and sodium bicarbonate (baking soda), which will form gas after contact with moisture, which has the effect of fluffy pasta. Because the gas generated will volatilize and dissipate as the pasta ferments, these additives are basically harmless to the body.
The other type of aluminum-containing baking powder, which is mainly composed of ammonium alum and alum, can produce a large amount of carbon dioxide through chemical reaction to achieve a fluffy effect when making pastries. But at the same time, it is easy to have the problem of aluminum element residue.
Due to the relatively higher cost of using aluminum-free baking powder to make pastries, many businesses will quietly use aluminum-containing baking powder in violation of regulations.
What are the possible effects of excessive aluminium intake on the human body?
First of all, aluminum is not a trace element needed for human life activities, so there is no need for people to ingest any aluminum.
In addition, some related studies have pointed out that long-term excessive intake of aluminum may cause the following damage to the body:
1. Accelerate the aging process of the body.
For middle-aged and elderly people, excessive intake of aluminum can greatly increase the probability of osteoporosis, and may also cause anemia and accelerate the aging process of the human body. In addition, for developing children, excessive intake of aluminum can increase the risk of hypochondria.
2. Damage to brain tissue, causing memory loss.
Excessive intake of aluminium will accumulate in the human body and combine with proteins and enzymes in the body, causing liver and kidney function and brain tissue damage, resulting in memory loss, brain atrophy, and even dementia.
How to tell whether steamed buns and buns contain aluminum?
Pastries made with baking aluminum-containing powder usually have the following 3 characteristics:
First: the texture of the pastry will be relatively soft and fluffy, but it often has little toughness when chewed, and the taste is average
Second: if the pastry is broken and looked closely, you can clearly see that the fermented pores are very small and relatively evenly distributed
Third: the size of the pastry is often relatively large and white, and the fingers will be flattened when pinched, and the elasticity is poor, and it is not easy to restore itself.
