1, the alkali we are talking about is limited to edible alkali.
Edible alkali refers to soda ash (sodium carbonate) and baking soda (sodium carbonate) which are different from industrial alkali. Baking soda is the finished product after absorbing carbon dioxide from soda solution or crystal, and there is no difference between them in essence. Edible alkali is solid, round, white and easily soluble in water.
Alkali is not a common condiment, but a kind of food swelling agent and meat tenderizer, which can make dry raw materials swell rapidly, soften fibers and remove the sour taste of dough. Proper use can bring excellent color, fragrance, taste and shape to food, thus increasing people's appetite. Alkali is widely used in the processing of noodles, bread, steamed bread and other foods.
2, the harm of excessive alkali intake:
The disadvantage of edible alkali is that it has a strong destructive effect on vitamins B 1, B2 and vitamin C in food, and at the same time it will affect the absorption and utilization of certain minerals by human body. Don't overdo it.
