Supplement:
Distilled liquor also contains higher alcohols, fatty acids, aldehydes, esters and a small amount of volatile acids and nonvolatile acids. For example, northeast sorghum liquor contains formic acid, acetic acid, butyric acid, ethyl acetate, ethyl butyrate, rongyl acetate and rongyl butyrate, and a small amount of propanol, butanol and rongol. Non-distilled liquor, such as Shaoxing rice wine, also contains organic acids, sugars, glycerol, esters and aldehydes; Yellow rice wine also contains more sugars, organic acids and so on. A small amount of alcohol and alcohol with low alcohol content (about 10%) can increase the secretion of saliva and gastric juice and promote gastrointestinal digestion and absorption. Ethanol is absorbed quickly in the gastrointestinal tract, and low-concentration wine is easier to absorb than high-concentration wine. Most of the ethanol entering the body is completely oxidized, releasing heat, and a small amount of unoxidized ethanol is mainly discharged through the kidneys and lungs. Proper amount of ethanol can promote blood circulation and dilate blood vessels in the skin, so it often makes the skin ruddy and warm, but it can't last long, and eventually the heat dissipates. Ethanol can weaken the inhibitory function of the brain, showing a long-term excited state. Non-distilled liquor has different degrees of nutrition and tonic effects. ?
