[ Products Name ] Nisin
[ About Nisin ]
Nisin is a food preservative which is well-known around the world. Nisin is developed by Microbiology Research Institute of the Science Academy of China, B&K Technology Group (China ) Co., Ltd. as part of a major programe by the Chinese government to develop products for the Chinese food industry.
[ Molecular formula] C143H228O37N42S7
Natural Preservative Nisin:
[ Molecular weight ] 3352
[ The character of Nisin ]
Since Nisin (also known as Streptococcus lactic peptide) is a polypeptide, it is rapidly inactivated in the intestine by digestive enzymes after consumption, Extensive micro-biological tests have not shown any cross resistant between Nisin and medical antibacterial drug. Nisin possesses anti-microbial activity against a wide range of Gram-positive bacteria and their spores which causes food spoilage, and especially inhibits the heat-resistant bacilli, such as B. Stearothermophilus, CI. Butyricum and L. Monocytogenes. It is a natural food preservative which is highly efficient, safe and has no side-effects. In addition, it has excellent solubility and stability in food. It is not effective against Gram-negative bacteria, yeasts or mould.
[ Application ]
Nisin can be used in a wide range of heat-processed foods. These include: fresh milk, processed cheese and other dairy products, pasteurised liquid egg, processed meat, seafood, canned food, fruit drinks, plant protein drinks, baked products, instant food, beer, wine ect. It can also be used as a preservative in gelatin processing, cosmetics, drugs and health products.
General dosage:0.03-0.2gram per kilogram food to be processed Nisin dissolve well in low pHcondition. You may confect solution with PH3-4 and containing 5%Nisin preparation by adding diluted acetic acid, diluted citric acid or 0.02ml/l HCL first, then put it into the food and mix fully. Or, dilutegradually and add. Sometimes, Nisin can be dissolved directly in the original soup of the food. Nisin can also be used together with other food preservatives.
[ Packaging ] 100g 500g or packed to customer’s requirement.
[ Expiration ]
2 years in cool (0℃-10℃)dry conditions, away from direct sunlight in original unopened packs.
Our Nisin conforms to International specifications for nisin, including FAO/WHO, EU, and US FDA. It is manufatured in accordance with the Chinese Light Industry standard QB2394-98 and it meets the requirement of the Pople’s Republicof China Agriculture Standard NY/T392-2000 for using additives in producting green foods. The products is registered with USA FDA, and certified HALAL&Kosher(Parva). Our new, state of the art factory can totally meet the rising demand for high quality nisin in domestic and international markets. Our technical research team is able to test the efficacy and use of nisin in food products, and assist clients in application development trials.

[ Products Name ] Natamycin
[ Introduction ]
Natamycin( Pimaricin ) is an antimycotic product which have broad and effective action. It not only inhibits the growth of different moulds and yeasts, but also inhibits the production of their toxin. Commercial Natamycin contains 50% of the active substance. Small quantities of Natamycin can inhibit all moulds and yeasts, which cause food spoilage. Natamycin has no effect on bacteria, so it does not prevent in the natural maturing process of yoghurt , cheese , fresh Ham, sausage, ect.
[ Molecular formula ] C33H47NO13
[ Molecular weight ] 665.75
[ Physical characteristic ]
Natamycin is a white to yellow flavourless, odourless crystalline powder. It is very stable with its crystal form. The solubility of Natamycin is very low in water and in most organic solvents. Only 50mg Natamycin can be dissolved in pure water at room temperature. The low solubility makes it very suitable for use on the surface of food. Natamycin will stay on surface of food, where most moulds and yeasts may grow, but does not influence the natural course of fermentation inside.
[ Chemical characteristic ]
As seen from the molecular structural, Natamycin is polyene macrolide antimycotic. But it is very sensible to oxidation and ultraviolet radiation.
[ Microbiological characteristic ]
Natamycin can hinder almost all the fungi (moulds and yeasts), but could not result in bacteria, virus or other microorganism.
[ The activation and stability ]
Many factors can influence the stability of Natamycin: acidity (PH value), temperature, light, oxygen, heavy metal, etc.
[ Usage ]
Food preservative. Ideal result can be achieved by using Natamycin on the exposed surface of the food where the moulds and yeasts may grow. This is especially useful for cheese manufacture, since the mould growth is prevented, while the cheese ripening bacteria will grow and metabolize normally. The product should be stored in dry, cool (not exceeding 15) places, in original sealed container, and prevent from direct sunlight.
[ Application standard ]
1. U.S.A.: FDA, 172. 155, 2000: Treat (Spray or dip) the surface of the cheese with 200-300mg/kg aqueous solutions.
2. EU: Permitted on the surface of cheese and sausage casings
3. China: GB2760-2001: for cheese, meat and meat products, moon cakes, snacks, raw juice for coating use, surface of utensils, perishable food, Salad sauce, Fermented wine, etc.
The FAO/WHO Joint Expert Committee on Food Additive confirmed the acceptable daily intake (ADI) if Natamycin as 0.3mg/KG (total body weight). This was also endorsed by the EU. In China its use is permitted in the food industry.

[ Products Name ] ε-Polylysine, ε-PL, epsilon-Polylysine
[ About ε-PolylysineDescription ]
ε-Polylysine is a natural substance from streptomyces albulus metabolism. It is widely used as food preservative. It can inhibit the growth of Gram-positive and Gram-negative bacteria, yeasts, moulds, bacteria, properties ε-Polylysine is hygroscopic, light yellow power. It is soluble in water, slightly soluble in ethanol, insoluble in organic solvent such as ethyl acetate, ether, The molecular of ε-Polylysine is a straight chain polymer of lysine. It can decompose for lysine within the human body, and can be completely digested absorption by the human body not ε-Polylysine can inhibit the growth of Gram(+) and Gram(-) bacteria , yeast, mould, virus, ect., especially inhibit the Gram(-) bacteria which can’t easily inhibit by other preservatives such as Salmonella, and also can inhibit the thermophilics, such as B, stearothermophilus. Its activity is not affected by PH, and stable when heated (120℃ for 20min). Therefore, it can be sterilized along with the raw material. It is a food preservative which is highly efficient, safe, and has no side-effects.
Quality standard; FAO/WHO, 1992
1. content ≥ 95%
2. heavy metal (as Pb) ≤20ppm
3. weight lost when drying ( 105℃, 3h) ≤20%
4. Ash ≤1%
[ Range of application ]
ε-Polylysine was generally recognized as a safe food preservative by FDA in October, 2003. It is widely used in food preservation. In food application, it is usually applied with alcohol, organic acids, or glyceride, ***** It can be used in cooked rice, cakes, snacks, noodles, drinks, brewing, meat products, canned food, etc.
[ Usage ]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.
[ Packaging ] 0.1kg, 0.5kg, 5kgor packed to customer’s requirements. [ Storage ] store in well-closed container, away from direct sunlight. |
