  • L(+)-Lactic acid

    Chinese Name: L-lactic acid

    Chinese alias: l-anhydrous lactic acid

    English Name: l (+) - lactic acid

    English alias: (s) - (- +) - 2-hydropanoic acid; L(+)-Lactic acid solution; L-Lactic acid, free acid; lactate standard 40 mg/dl; L(+)lactic acid free acid sigmaultra; L-Lactic acid; (S)-2-Hydroxypropionic acid

    CAS:79-33-4

    EINECS:201-196-2

    Molecular formula: C3H6O3

    Boiling point: 125 ℃

    L-lactic acid is an organic acid refined from corn starch through biological fermentation. It is a colorless, clear and viscous liquid, and the aqueous solution is acidic. It can be freely mixed with water, ethanol or ether and is insoluble in chloroform. Because of its left-handed characteristics, it has good biocompatibility, can be compatible with mammals, can directly participate in human metabolism, without any side effects, and is widely used in food, medicine and other fields;

    Main uses: it can be used in fruit wine, beverage, meat, food, pastry production, pickle of vegetables (olives, cucumbers, pearl onions), canned processing, grain processing and fruit storage. It has the functions of adjusting pH value, bacteriostasis, extending shelf life, seasoning, maintaining food color and improving product quality.

  • Poly(lactic acid) (Low M.Wt.)

    Bending modulus: 100-150 MPa

    CAS NO.:26100-51-6

    Tensile strength: 40-60 MPa

    Elongation at break: 4-10%

    Elastic modulus: 3000-4000 MPa

     


    Polylactic acid (PLA) is a new type of biodegradable material, which is made from starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are made into lactic acid through fermentation, and then converted into polylactic acid through chemical synthesis.

     


    Application: extrusion grade resin, mainly used for fresh fruit packaging; Secondly, it is used in the packaging of electronic products that promote safety, energy saving and environmental protection. In addition, the application of extrusion grade resin in Horticulture has also begun to get attention. At present, it has been applied in slope greening, sand storm control and other fields.
