Details

All the fine nano-zinc oxide in the manufacturing process or the premise of the feeding process, is generally considered safe food additives. A wide range of zinc exist in vivo as well as the body of the trace metal content of most elements of the needs of all living organisms are zinc, and zinc is a component of all cells, as many of the fundamental co-factor enzyme system (Cofactor). Adult recommended daily requirement of zinc should be 15mg, while mothers are breast-feeding should have 25mg. Zinc oxide particle size because of its size for the nano-level, more easily absorbed into the body.
At the same time, Zinc oxide has a broad-spectrum (UVA and UVB) and the anti-ultraviolet anti-bacterial, sterilizing function. Food can be added to the antibacterial, bactericidal, and maintain food fresh and slow deterioration of food.
