Industrial grade glacial acetic acid 02 acetic acid, also known as acetic acid (36%-38%), glacial acetic acid (98%), chemical formula CH3COOH, is an organic mono acid and is the main component of vinegar. Pure acetic acid anhydrous (glacial acetic acid) is a colorless hygroscopic solid with a freezing point of 16.6℃ (62℉). After solidification, it is a colorless crystal. Its aqueous solution is weakly acidic and highly corrosive, and the steam has irritating effects on the eyes and nose. Acetic acid can be used as acidity regulator, acidifier, pickling agent, flavor enhancer, flavor enhancer, etc. It is also a good antimicrobial agent, mainly due to the fact that it lowers the pH below the pH required for microbial growth. Acetic acid is an early and widely used acidulant in China. It is mainly used in compound seasonings, prepared waxes, canned food, cheese, jelly, etc. When used in seasoning, acetic acid can be diluted with water to 4% ~ 5% solution and added to various seasonings. Drinks made with vinegar as an acidulant and supplemented with nutritional supplements are called international third-generation drinks.
