Can alum be eaten?

Alum is a product that seems to have no effect, but actually has a great effect. It is mainly composed of chemical structure. Because it looks transparent, crystal clear and white, it is called alum. Alum has a wide range of uses, and most of them are made from some extracts. Alum is not only cold in nature, but also tastes slightly sour and has a strong astringent effect.

Also known as: alum, white alum, potassium alum, potassium aluminum alum, potassium alum

It is a complex salt of potassium sulfate and aluminum sulfate containing water of crystallization. The chemical formula is KAl(SO4)2·12H2O, the addition formula is K2SO4·Al2(SO4)3·24H2O, the relative molecular mass is 474, colorless cubic, monoclinic or hexagonal crystals, with glass luster, density 1.757g/cm3, melting point 92.5℃. It loses 9 molecules of crystal water at 64.5℃ and 12 molecules of crystal water at 200℃. It is soluble in water but insoluble in ethanol. Alum is sour, astringent, cold and poisonous.

Therefore, it has antibacterial and astringent effects, and can be used as a traditional Chinese medicine. Alum can also be used to prepare aluminum salts, baking powder, paints, tanning agents, clarifiers, mordants, papermaking, waterproofing agents, etc. At 20 degrees and 1 standard atmosphere, the solubility of alum in water is about 5.90g. Purifying water with alum was a method often used by the public in the past. Its principle is that alum can ionize two metal ions in water.

Aluminum hydroxide colloid has a strong adsorption capacity. It can adsorb impurities suspended in water and form precipitation to make the water clear. Therefore, alum is a better water purifier.

Alum can be obtained from alum stone by calcination, extraction and crystallization. The Lujiang alum mine in Anhui Province is located in my country.

The largest alum producing area in my country should be the alum mine in Fanshan Town, Cangnan County, Zhejiang Province (accounting for 67% of the world's total reserves).

Alum, also known as white alum, is a refined product of alum stone. Alum is cold in nature, sour and astringent in taste, and has a strong astringent effect. Traditional Chinese medicine believes that alum has the effects of detoxifying and killing insects, drying dampness and relieving itching, stopping bleeding and diarrhea, clearing heat and eliminating phlegm. Research in recent years has confirmed that alum also has antibacterial and anti-trichomoniasis effects. Some Chinese medicine practitioners use alum to treat diseases such as hyperlipidemia, duodenal ulcers, and hemoptysis caused by tuberculosis.

In addition, alum is also a traditional food improver and leavening agent, and is often used as an additive in the production of foods such as fried dough sticks, vermicelli, and rice noodles. However, since the chemical composition of alum is potassium aluminum sulfate, which contains aluminum ions, excessive intake will affect the body's absorption of iron, calcium and other components, leading to osteoporosis, anemia, and even affecting the development of nerve cells. Therefore, some nutrition experts suggest that we should try to eat less foods containing alum.

In recent years, it has been discovered that the aluminum contained in alum is harmful to the human body. Long-term drinking of water purified with alum may cause Alzheimer's disease. It is no longer recommended to use alum as a water purifier.
