Vitamin C, also called ascorbic acid , is indispensable during the growth and propagation of animals , it can sustain normal blood-fat metabolism , cardiac function , central nerve function and haematopoietic function and 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. The research and development personnel adopts new dressing and advanced manufacture equipment to microencapsulate and insulation block Vitamin C. Thus it can avoid its contact with harmful environment factors and possess moisture-resistant, heat-resistant, ultraviolet-resistant and inoxidizable factors. So the stability of vitamin C is greatly improved .In 2000á? Super VC won Golden Elephant Award fro 21st century farming industry technology harvest forum and products promotion seminar in Bangkok
