Cooking tips:The main component of protein in pigskin is collagen, accounting for about 85%, followed by elastin. Biological research has found that collagen is related to the ability to bind to water. The lack of collagen, which belongs to biomacromolecule gum, will hinder the mechanism of water storage in cells in vivo. The water binding capacity of cells is obviously reduced. The human body will be dehydrated. Light will make the skin dry, desquamate, lose elasticity, wrinkle, and heavy will affect life.
