Quality standard: FAO/WHO,1992Content: >=87%heavy metal (as Pb):= <20ppmweight lost when drying (105°C,3h):= <20%Ash: = <1%Toxicity: LD50>5g/kgPackage: packed to customer’s requirements.Description: Polylysine is a homopolymer of L-lysine, as a natural, toxicologically safe, antibacterial food preservative. It is a natural substance from microbial metabolism. E-polylysine can inhibit the growth of Gram(+) and Gram(-) bacteria such as E. Coli and Bacillus subtilis, yeast, moulds, lactic acid bacteria, thermophilics such as B,stearothermophilus, bacillus-bacilli., and Staphlacoccus aureus, ect…Compared to traditional preservatives, E-polylysine shows the advantages on safety, good heat tolerance and solubility in water, and extensive antimicrobial ability against Gram+ bacteria and fungi. It can be sterilized along with the raw material, especially as the safe food preservative without side-effects.Physical properties:ε-Polylysine is slightly bitter, hygroscopic, light yellow powder.It is soluble in water, slightly soluble in ethanol, insoluble in organic solvent such as ethyl acetate, ether, ect... The molecular of E-Polylysine is a straight chain polymer of L-lysine. Its activity is not affected by pH, and stable when heated (120C for 20 min).It is soluble in water, slightly soluble in ethanol, insoluble in organic solvent such as ethyl acetate, ether, ect.. It can decompose for lysine within the body, and can be completely digested absorption by the body.Usage: E-Polylysine was generally recognized as safe as food preservative by FDA in October, 2003. It is widely used as food preservation in rice, noodles, cakes, snacks, and ice creams, salad, canned foods and meat products.It can be automatically hysrolized into nutritive amino acid, lysine without any harm to the body. It can also be used as a carrier for pharmaceutical molecules. With good absorption of liquid, it is used in SAP to produce sanitation products, such as sanitation napkin and diapers.You may confect the 5-10%ε-Polylysine solution with cold boiled water or distilled water, then put it into the food and mix fully. If it is used together with other food preservatives, can attain better effect.Storage: Please store the product in well-closed container, away from direct sunlight.
