    摘要: A method for preserving soy sauce which comprises admixing therewith acetic acid and a salt of acetic acid, propionic acid, butyric acid, malic acid, tartaric acid, citric acid or lactic acid. The amount of the acid salt is in excess of the amount of acetic acid. The method provides a sufficient antiseptic effect without producing a sour taste and without greatly lowering the pH.
