L-lactic acid ethyl lactate is the main variety of wine aroma components
L-lactic acid can be used in food, beverage, pharmaceutical plastic, feed, pesticides, household chemicals, paper And electronic industry and other fields. In the food, beverage industry, Sodium lactate as a sour agent, strong
Agents, preservatives, additives, is absolutely safe. L-lactic acid
Derivatives such as L-lactate, L-lactic acid zinc, L-lactic acid ferrous food, beverage, health care products Enhancer, L-lactic acid ethyl lactate is the main variety of wine aroma components. In the pharmaceutical industry In, L-lactic acid and derivatives thereof (such as L-lactate) with sodium chloride, amino acids, such as compatibility,Production treatment of hyperkalemia or acidosis infusion, potassium lactate and other drugs are also used Luo Fusha Star Matter production. Lactate is a good organic solvent for the production of alkyd resins, inks And coatings and other products. The material world, the star of the environmental protection industry is the use of lactic acid Production of new polyester - polylactic acid (PLA), the material not only has excellent mechanical
Properties, making it capable of use of other synthetic plastics, and can be reduced with good biological Solution performance, and because of its raw materials from renewable biological resources, they were identified as a new industry Century's most promising new material.
