Wholesale Beef Extract Paste High-Concentration Organic Nitrogen in Fermentation Manufacturers, Manufacturer

Beef extract paste is a tan or dark brown paste obtained from fresh beef which is defatted, enzymatically hydrolyzed, filtered and concentrated. It is rich in creatine, creatinine, peptides, amino acids, nucleotides, organic acids, minerals, vitamins and other water-soluble substances. In addition, it is high in methionine, vitamins and other growth factors essential for bacterial growth. It complements the nutritional profile of peptone and other nitrogen sources, serving as a high-grade raw material for the microbial fermentation industry.

Made with premium raw materials, beef extract paste features high purity, low impurities and excellent batch stability, perfectly meeting the demands of biopharmaceuticals and various microbial fermentation applications.
