whats the coated coated Ascorbic Acid

Viamin C, also called ascorbic acid,  is the indispensable during the growth and propagation of human espscially animals.  It sustain normal blood-fat metabolism, cardiac function,  central nerve function and haematopoietic function. It also can promote the synthesis of various hormones in organism.  But , since the structure of VC molecule is very unstable,  it is readily destroyed and deactivated in the presence of light ,heat , damp and metal ions.  The losses of feedstuff are very great during drying , storing, processing and transporting.  Our MINSHENG Company adopts new excipients and advanced production to process the vitamin c microencapsulated , keep it isolation protection and avoid the contact with environmental factors, improve the stability.

So that it has the characteristicfs of the high temperature resistance, oxidation resistance, moisture-resistant, heat-resistant,  ultraviolet-resistant etc.
