D-Tartaric acid Use and Manufacturing
Tartaric acid is mainly present in the fruits of various plants in the form of potassium salts, and also exists in a small amount in the free state. Glucose fermentation is commonly used in industry to produce dextrotartaric acid; the racemate can be prepared by oxidation of fumaric acid with potassium permanganate; the meso form can be prepared by oxidation of maleic acid with potassium permanganate; L-vinic acid can be obtained by resolution of racemate. In the practical application field of tartaric acid, dextrotartaric acid or its double salt is mainly used. The tartaric acid, a by-product of brewing grapes, is currently the main raw material for the actual production of tartaric acid, and the tartaric acid produced is all dextran.
Tartaric acid is widely used as an acidulant in beverages and other foods, and its use is similar to citric acid. Tartaric acid is used in combination with tannins to be used as a mordant for acid dyes. It is also used in certain developing and fixing operations in the photographic industry. Its iron salt has photosensitivity, so it can be used to make blueprints. Tartaric acid can complex with a variety of metal ions and can be used as a cleaning agent and polishing agent for metal surfaces. Potassium and sodium tartrate (Rochelle's salt) can be used to prepare Fehling reagent, and can also be used in medicine as a laxative and diuretic, and also as an intermediate of Sincofen. The crystal has piezoelectric properties and can be used in the electronics industry. Used as a chromatographic analysis reagent and masking agent; used as a pharmaceutical resolution agent, food additive, biochemical reagent, etc. This product is widely used in the food industry, such as beer foaming agent, food acidulant, flavoring agent, and refreshing beverage , Candy, juice, sauce, cold dishes, baking powder, etc. This product complies with the Japanese Food Additives Regulations.
