Hydrolyzed animal protein (hydrolyzed gelatin)is used the animal collagen connective tissue as raw materials to be refined,strict controlled in the condition of hydrolysis. It contains 18 kinds of amino acids,7% of itmust be used in the human , it also contains necessary part of the trace metal element that body must uses.Hydrolyzed animal protein hashigh nutritional value andsuperior performance, is good natural physiologically active substances.It does not contain the cholesterol. So in the food, cosmetic, pharmaceutical, oil and chemical industry, it has wide usage. Hydrolysis product molecular weight are 2000-6000 molecular ,among it18 kinds of amino acid is more than80% ,and protein content is more than 80%.It is beloong to low molecular peptide.its color is white.It has excellent performance of protective colloid, surface activity, film, aggression, stability and solublity.It has cushioning force against acid and alkali etc.stimulating substance. Hydrolyzed animal protein is a good kind of fibrinogen,it contains collagen human body needed and acid componentis similar to Ejiao.Because its molecular weight isappropriate,water soluble is good,it can be easily absorbed by body.It is called functional food.It is widely used in nutritional liquid,nationalYoghurts,beverages,drinkingcosmetics,nutritionalhealth,condiments,bread ,convenient noodles,instant amino acids,granule etc.It is aldo good to hair,nail and skin.It can also used in pharceutical industry. Hydrolyzed animal protein is also good for hepatitis,gastritis and gastrointestinal diseases,can be used in clinical treatment and medical care foods manufacturing.It can be used as elixir filling material,blood plsma expander,bacteria culturing and HeMiao bacteria stabilizer etc.
