Nisin & Natamycin
Molecular formula: C141H228 N41O38S7
Molecular weight: 3352
is a food preservative which is well-known around the world. "
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, vinegar, sauce, soy sauce, composite flavorings, 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.
100g\500g\5kg\10kg or packed to customer's requirement.
2 years in cool ( 0-10C), dry conditions, away from direct sunlight in original unopened packs
2. Natamycin (Pimaricin)
Molecular formula: C33H47NO13
Molecular weight: 665.75
-Natamycin 50% in NaCL
-Natamycin 50% in Lactose
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.
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 15C) places, in original sealed container, and prevent from direct sunlight.
