After soaking in alum water, the rice noodles will become more smooth and tender, which is caused by the addition of edible alum. Alum is mainly composed of aluminum sulfate. If it is consumed for a long time, it will cause damage to the human body. The early symptoms are weakness, depression, anxiety and memory loss. If it is serious, it will cause renal failure and uremia. If it is deposited too much in the brain, it will cause dementia and Parkinson's disease.
Prevention of alum poisoning
Therefore, the use of alum should be strictly regulated because the aluminum contained in alum will deposit in the human body through gastrointestinal absorption. Excessive alum will cause damage to the human body. Mild alum will cause physical weakness, depression, anxiety, memory loss and other conditions. Severe alum will even cause renal failure and uremia. If excessive alum is deposited in the brain, dementia and Parkinson's disease will occur.
Because alum can enhance transparency and toughness, and achieve the effect of long cooking, many manufacturers add excessive alum in the processing of melon seeds, vermicelli, vermicelli, Jinggao and other food, so as to achieve the effect of good selling. In addition, alum has a fluffy effect, and some vendors also use alum illegally in the processing of fried dough sticks and cakes.
Add excessive alum food, will appear particularly transparent or fluffy crisp, so in the selection time to pay special attention to. In addition, especially for pregnant women, aluminum will invade the fetal brain through the placenta, affecting the child's intellectual development, so pregnant women should eat less fried dough sticks and cakes.
matters needing attention
The chemical formula of alum is Kal (SO4) 2.12h2o, which hydrolyzes in water to form aluminum hydroxide colloid. Aluminum hydroxide colloid has strong adsorption, so it can purify water. But too much will lead to aluminum poisoning, causing intellectual problems to children. Remind you, don't eat so much fried dough sticks outside, because many of them are added alum.
