Shandong Freda Biotechnology Natamycin is an antifungal compound produced by the fermentation of Streptomyces. It belongs to the polyene macrolides. It can not only inhibit the growth of molds and yeasts, but also inhibit the production of mycotoxins. It is widely used in food preservation and anti-fungal treatment. Natamycin has no inhibitory effect on bacteria, so it does not affect the natural maturation process of yogurt, cheese, raw ham, and dried sausage.

Shandong Freda Biotechnology Pullulan is a water-soluble polysaccharide produced by the fermentation of Aureobasidium pullulans. It has excellent adhesion and oxygen barrier properties. It can be quickly dissolved in water, the solution is neutral, has the characteristics of non-ionization and non-gelation, and is miscible with other food colloids, and can be widely used in food and cosmetics fields.

Shandong Freda Biotechnology Gamma-aminobutyric acid is an amino acid. As an important inhibitory neurotransmitter in the central nervous system of animals, it can bind to GABA A receptors and reduce cell excitability. GABA can affect heart rate and blood pressure, and is used for sedation and anti-anxiety treatment.

Shandong Freda Biotechnology Nisin is a polypeptide produced by microbial fermentation and can effectively inhibit the reproduction of Gram-positive bacteria and pathogenic bacteria. It has a strong inhibitory effect on thermotolerant bacillus and spores. It can be widely used in food and cosmetics. And other fields.

Shandong Freda Biotechnology Soluble Natamycin is easily soluble in water, prepared by a special process, solves the application problem that natamycin is difficult to dissolve in water.The preparation of high-clarity, high-concentration natamycin aqueous solution broadens the application fields of natamycin..

Shandong Freda Biotechnology ε-polylysine is a bacteriostatic peptide produced by Streptomyces albicans through aerobic fermentation. It is generally formed by the polymerization of 25 to 35 L-lysines with a molecular weight between 3500 and 5000. It is often used as Used as a biological preservative, it has the advantages of wide antibacterial spectrum, good heat resistance, and wide pH adaptability, and is widely used in food and daily chemical industries.
