pharmaceutical industry and manufacturing lactic acid derivatives

Lactic acid in the food industry as sour agents, preservatives and food supplements, etc., currently living Total consumption of lactic acid industry, the food industry accounts for about 60%, mainly for the pharmaceutical industry and other manufacturing Lactic acid derivatives. The world's annual production capacity of approximately 200,000 tons of lactic acid, the actual consumption of about 15 Tons. China's Sodium lactate production capacity of about 3 to 4 tons, the product purity lower than the cost of production High, and expected in 2005 China L-lactic acid demand will reach 20,000 tons or more. In order to meet the domestic Foreign demand for lactic yearly growth situation, we must accelerate the production and quality Development. In recent years, many countries have to solve the "white pollution" problem, the development of L-lactic acid obtained by the polymerization of the potassium lactate  such polymers have good biocompatibility and Biodegradability, the ultimate degradation products are carbon dioxide and water, decomposition of intermediate product milk
Acid harmless, so in the United States, Japan and European countries due to extremely broad interest and Large-scale production and has been put on the market.
