What other uses are there? What is its composition? For this reason, I specially looked up the knowledge about vinegar on the Internet.

The main component of vinegar is acetic acid, the chemical name is acetic acid, and the structure abbreviation is CH3COOH. Vinegar brewing mainly takes grain as raw material and strains are fermented. After saccharification, alcohol fermentation, acetic acid fermentation, subsequent disinfection and sterilization, processing and packaging, it has the characteristics of color, fragrance and rich nutrition through scientific analysis.

I. protein and amino acids

Vinegar contains 0.05% ~ 3.0% protein, and there are 18 kinds of amino acids, among which 8 kinds are essential for human body.

Second, carbohydrates

Vinegar contains a variety of sugars, such as glucose, maltose, fructose, sucrose, rhamnose and so on. These components play a very important role in regulating the concentration and softness of vinegar, and are also beneficial to health care.

Third, organic acids

The content of acetic acid in vinegar is the most, which can promote the increase of antibodies in blood and improve human immunity, and has good bactericidal and bacteriostatic effects; In addition, there are lactic acid, formic acid, citric acid, malic acid, pyruvic acid and succinic acid, which can promote metabolism and intracellular redox.

Four. Vitamins and minerals

Fermented vinegar also contains vitamin B 1, vitamin B2, and iron, sodium, calcium, zinc, phosphorus and copper ions in minerals, especially calcium acetate, which can alleviate the effect of acetic acid and have seasoning and blending effects on sauce, pickled vegetables, mayonnaise, fish cakes, sausages, rice cakes and bread. Proper coordination of these ions is necessary and beneficial to human nutrition, lowering blood pressure and preventing aging.

Verb (abbreviation of verb) aroma components

Although there are few aromatic components in vinegar, ethyl acetate, ethanol, acetaldehyde and 3- hydroxybutanone give vinegar special fragrance and flavor. Volatile substances and aromatic substances in vinegar can stimulate the brain center, make digestive juice secrete in large quantities, and improve digestive function. The requirements for vinegar should have the normal color, aroma and taste of fermented vinegar, without astringency, other bad smells and peculiar smells (such as musty smell), turbidity, suspended solids and sediments, moldy flowers and floating films. The aroma of vinegar comes from various esters produced in the fermentation process and various spices artificially added. Esters are mainly acetic acid and ethyl ester, in addition to isoamyl acetate, ethyl isovalerate, ethyl lactate and ethyl succinate. Due to the slow esterification reaction, the new vinegar brewing process has short fermentation cycle, low ester content and insufficient aroma. The fermentation period of mature vinegar is long, so the aroma of vinegar is rich and the mature vinegar is better. China vinegar has a long history and diverse flavors, and it is unique in the world.

For example, fried mung bean sprouts can not only make bean sprouts crisp and delicious, but also preserve vitamin C from loss.
