2.When brewing beer, adding suitable amount of lactic acid can adjust pH value, promote the saccharification, yeast fermentation and improve the quality of beer, and increase beer flavor, prolong shelf life.In liquor, wine and fruit wine used to adjust pH value, prevent bacterial growth, enhance the acidity and refreshing taste;5. Buffer lactic acid can be used in hard candy, fruit and other candy products, moderate acidity and sugar conversion rate is low.Lactic acid powder can be used in all kinds of candy on the powder, as the powder of citric acid;
and etc
pharmaceutical fields
medicine is widely used as a preservative, carrier agent and cosolvent, pharmaceutical preparations, pH regulator, etc
2. Lactic acid polymerization of poly (lactic acid, polylactic acid can smoke into silk spinning into line, this line is a good surgical suture, healing after don't have to remove the seam, can automatically degraded into lactic acid absorbed by the body, no bad consequences.Especially in surgical suture, exempt from secondary surgery to remove the trouble.This kind of polymer compounds can make adhesive application in organ transplantation and bone;
