dl-malic acid

Malic acid is an organic compound with the formula HO ₂ CCH ₂ CHOHCO ₂ H. This dicarboxylic acid is the active ingredient in many sour or tart foods. Malic acid is found mostly in unripe fruits.   CAS : 617-48-1 formula : C4H6O5
molecular weight : 134.09
melting point : 101-103 ° C Purity:99.5% Standard: FCCIV,1996 Packing:25KGS bag , 19MT/20FCL.
Properties : malic acid in normal circumstances stability and high humidity are hygroscopicity. Soluble in methanol, ethanol, acetone and many other polar solvents.
Production Methods : fumarate or maleic acid catalyzed by the high temperature and high pressure water can be obtained DL-malic acid. Will fumarate dissolved in distilled water and preheat to 50 °C by adding high pressure within the reactor. Heated to a 180-199 °C, pressure of 1MPa, the reaction after 8h down to 100 °C, pressure up reaction. At 60 C under vacuum condensation and precipitation crystallization. Then cooling, dehydration, drying derived products. The yield of 88%. Malic acid, a major producer of fermentation method, using variations of carbohydrate yeast fermentation obtained.

Application : as a cool drink ilizers (pure cold drinks, cold drinks condensed, powder cold drinks, milk, milk drinks, soft drinks, cola drinks), cold foods ilizers (sherbet, ice cream), the food-processing ilizers (gum, fruit sugar, fruit sauce, orange jam, ketchup, hot sauce, vinegar, fruit wine, mayonnaise, margarine), Antacids, fruit drinks and so on to keep the colors, preservatives (such as mayonnaise emulsion stabilizers). DL-malic acid with sodium carbonate solution and, vacuum concentration system in DL-malic acid ([63474-37-3]). As well as a condiment, nephritis patients salt substitutes. For Apple ester margarine and other edible oil additives. Malic acid in the non-food uses can be used as medicine, cosmetics ups, scaling fluid, metal cleaning agent, buffer, the textile industry resistance coagulant, industrial Deodorizing agent, polyester fiber fluorescent whitening agent of raw materials, manufacturing and alkyd resin monomer. DL-malic acid and L-malic acid is a safe and non-toxic substances, used for flavor intensifier, scented agent, supplementary drug and pH control agent
