Description	Widely distributed in nature as a fermentation product from starch, molasses, potatoes etc. "Natural" lactic acid is produced commercially by fermentation of beet/cane sugar or glucose. No commercial lactic acid is dairy-based. Synthetic lactic acid is a racemic mixture of the L- and D-forms. Among the oldest known preservatives used to preserve milk products and a broad range of traditional fermented vegetables. The modern use of lactic acid as a food additive covers several functions: flavouring, acidity control, preservation. Due to its mild flavour, lactic acid can be used in high concentrationsand is also in brewing, manuf. of cheese and confectionery_x000D_ _x000D_ Lactic acid is chiral and has two optical isomers. One is known as L-(+)-lactic acid or (S)-lactic acid and the other, its mirror image, is D-(-)-lactic acid or (R)-lactic acid. L-(+)-Lactic acid is the biologically important isomer. Lactic acid is found in many foods, some of which are sunflower, apple, common grape, and borage.
