laevo-(+)-tartaric acid
tartaric acid (+)-, (-)-, (+/-)-, meso-
 
Notes:
Present in many fruits, wines and coffee. Acidulant for beverages, foods and pharmaceuticals,used to enhance natural and synthetic fruit flavours, esp. in grape- and lime-flavoured drinks and candies. Firming agent, humectant. Used in leavening systems including baking powders. Stabiliising agent for ground spices and cheeses to prevent discoloration. Chelating agent in fatty foods. Synergist with antioxidants, pH control agent in milk, jams and jellies, moisture-control agent. *Metatartaric* acid (a mixt. of polyesters obt. by the controlled dehydration of (+)-tartaric acid, together with unchanged (+)-tartaric acid) is permitted in wine in UK Natural tartaric acid isomer (Wikipedia)
