Many people know that eating some sour fruits or drinking 1~2 clean vinegar can relieve hangover. What is the truth? This is because fruits contain organic acids, such as malic acid in apples, citric acid in oranges and tartaric acid in grapes. The main component of wine is ethanol, and organic acids can interact with ethanol to form esters to achieve the purpose of hangover relief. Similarly, vinegar can relieve alcoholism because it contains 3%~5% acetic acid, which can be esterified with ethanol to produce hexyl acetate.
