Fish peptone, a premium product from China, is a light yellow to yellowish fine powder derived from fresh fish bones through advanced biological extraction technology. The meticulous production process includes raw material cleaning, enzymatic hydrolysis, centrifugal separation, decolorization, purification, vacuum concentration, and spray drying. This process effectively breaks down fish bone protein into small peptides and free amino acids while preserving water-soluble active substances, resulting in high purity and excellent solubility, As a high-quality organic nitrogen source, fish peptone is rich in small molecular peptides, free amino acids, trace elements, and growth factors, making it quickly absorbable by microorganisms. This efficiency promotes cell proliferation, protein synthesis, and metabolic enzyme activity, significantly enhancing strain growth density and fermentation stability, Our fish peptone is widely utilized in microbial fermentation, vaccine production, and various biological products, making it an essential ingredient in industrial fermentation. When combined with other medium components like yeast extract and malt extract, it optimizes nutrient matching and boosts the expression of target products. As a trusted supplier in the industry, our factory ensures that fish peptone meets the highest standards for scientific research and industrial production
