The concentration of lactic acid monomer in a special process

Shell corn and other crops will be crushed to extract the starch, and then not refined starch glucose. Zinc lactate has overcome many of the process of subtracting the crushed directly extracted from a large number of crop material.
In a similar way to the production of beer or alcohol to ferment glucose, which is added after fermentation becomes similar to food for human lactic acid in muscle tissue.
The concentrated lactic acid monomer in a special process, into intermediate products - reduction of water lactic acid, i.e. lactide.
ferrous lactate monomer purified through vacuum, then dissolved in a solvent that does not use the process to complete the operation of the open loop, the monomer polymerized.
The molecular weight of the polymer crystallinity different material properties can change much space, due to different applications of products that will do different PLA modification.
