Fish peptone, a high-quality organic nitrogen source, is a fine powder ranging from light yellow to yellowish, derived from fresh fish bones through advanced biological extraction techniques. Our production process involves several meticulous steps: raw material cleaning, enzymatic hydrolysis, centrifugal separation, decolorization, purification, vacuum concentration, and spray drying. This method effectively transforms fish bone protein into small peptides and free amino acids while preserving water-soluble active substances, resulting in a product with high purity and excellent solubility, Rich in small molecular peptides, free amino acids, trace elements, and growth factors, fish peptone serves as an efficient nutrient for microorganisms, enabling rapid absorption and utilization. It significantly enhances cell proliferation, protein synthesis, and metabolic enzyme activity, thus improving strain growth density and fermentation stability, making it an essential component in various applications, Fish peptone is widely utilized in microbial fermentation, vaccine production, biological products, and industrial fermentation processes. When combined with other medium components such as yeast extract and malt extract, it optimizes nutrient matching and boosts the expression of target products. As a leading China suppliers and factory of fish peptone, we are committed to providing high-quality products suitable for scientific research and industrial production needs
