melting point : 101-103 ° C
Properties : colorless crystal. Melting point 100 ° C and relative density of 1.595 (20 / 4 ° C), the boiling point of about 140 ° C (decomposition). Water-soluble. 1g the goods 1.4ml can be dissolved in alcohol, ether 1.7ml and 0.7ml methanol, 2.3ml propanol, almost insoluble in benzene. Purity:99.5% ,Standard: FCCIV,1996, Packing:25KGS bag , 19MT/20FCL.
Production methods : malic acid exists widely in nature, is the product of plant and animal metabolism, Apple is the main acid components. Will the immature apple, grape, peach juice and boil, joined limewater, generate calcium precipitation, and then to change their lead salts, treated free acid formation can be obtained by L-malic acid.
Application : used in the manufacture of derivatives; For complexing agents and flavorings. According to China GB 2760-90, can be used for various types of food. As ilizers can replace the use of citric acid (about 80%), is particularly applicable to jelly and fruit-based food materials. The goods have to maintain the natural color of the fruit, pectin can be as extraction agents, used to promote the growth of yeast agent, preparation without salt soy sauce, vinegar, pickles used to enhance flavor and margarine, Mayonnaise and other emulsion stabilizers. For a wide variety of preservation, Seasoning such as compound additives
