Edible acetic acid (Also as glacial acetic acid) I. Edible acetic acid is classified into two types based on its production process: 1.Acetic acid in alcohol process (Also as Alcoholic acetic acid) .  2.Carbonyl acetic acid. Ii. Uses of Edible Acetic Acid: Edible glacial acetic acid can be used as an acidulant and flavor enhancer, and is often applied in tomato sauce, mayonnaise, rice sugar sauce, pickles, cheese, and sugar products, etc.  III. The characteristics and applications of acetic acid produced by alcohol method: The preparation of acetic acid from ethanol (ethanol oxidation method), is a common chemical approach, mainly by oxidizing ethanol (alcohol) to obtain acetic acid. Ethanol is gradually oxidized under the action of oxidants such as acidic potassium permanganate, acidic potassium dichromate or oxygen/catalyst. Cost: The cost of small-scale laboratory preparation is relatively low, but in industry, the methanol carbonylation method (using methanol and CO as raw materia…
