Peptone is a soluble mixture of amino acids, small peptides and polypeptides produced by hydrolysis of animal protein raw materials. It is widely used in microbial fermentation, biological research, pharmaceuticals and industrial production due to its stable performance, high nutrition and good solubility.
With the rapid development of biopharmaceuticals and fermentation industries, high-quality animal peptone has become an essential raw material for industrial and laboratory applications.

Production Method of Animal Peptone

Animal peptone is produced by enzymatic hydrolysis or acid hydrolysis of animal protein materials.
Enzymatic Hydrolysis: Mild condition, high amino acid retention.
Acid / Alkaline Hydrolysis: High efficiency, low cost.
Production flow:
Raw material → Pretreatment → Hydrolysis → Filtration → Concentration → Drying → Packaging
