Food additives Preservative Calcium Propionate Calcium propionate CAS：4075-81-4 is white crystalline granule or crystalline powder. Odorless or slightly propionic acid odor, hygroscopic, soluble in water, insoluble in alcohol. Specification: Calcium propionate  Anhydrous  pharma grade Calcium propionate  Monohydrate Industrial grade Calcium propionate  Monohydrate  Food grade FCC Calcium Acetate Monohydrate  Pharma E281  * Please refer to Certificate of Analysis for lot specific data.  Application: 1) The bacteriostatic effect of calcium propionate liquid wet acid preservative is affected by PH of environment. The minimum inhibitory concentration was 0.01% at PH5.0 and 0.5% at PH6.5. In acidic medium, it has strong inhibition effect on all kinds of molds, aerobic bacillus or gram-negative bacillus. It has special effect on preventing the production of aflatoxin, but has almost no effect on yeast. In addition, it also acts as a preservative for food. 2) Used as food preservative and mildew prevention agent, it has extensive inhibitory effect on mold, yeast and bacteria 3) Used as an analytical reagent 4) Calcium propionate is also an acid food preservative whose bacteriostatic effect is affected by the Ph of the environment. The minimum inhibitory concentration was 0.01% at Ph 5.0 and 0.5% at Ph 6.5. In acidic medium, it has strong inhibition on all kinds of molds, Gram-negative bacillus or aerobic bacillus. It has special effect on preventing the production of aflatoxin, but has almost no effect on yeast. In the food industry, mainly used in vinegar, soy sauce, bread, pastries and soy products, the maximum use (propionic acid, the same below)2.5g/kg; The maximum usage in raw wet products is 0.25g/kg. Can also be used as feed mildew prevention agent. 5) Used as preservative for breads, pastries and cheeses, and as a mildew inhibitor for feed. As a food preservative, calcium propionate is mainly used in bread because sodium propionate raises the ph of bread and delays the fermentation of raw noodles. Sodium propionate is often used in pastries because the leavening of pastries is done with a synthetic leavening agent and there is no yeast development problem caused by pH rise. As a feed preservative, sodium propionate is better than calcium propionate. But calcium propionate is more stable than sodium propionate. Propionate in food in addition to bread, pastry, cheese, etc., can also be used in soy sauce to prevent mildew, inhibit re-fermentation. In medicine, propionate can be used as a powder, solution and ointment to treat diseases caused by parasitic molds of the skin. Ointment (liquid) contains 12.3% sodium propionate, powder 15% calcium propionate. Packing: 25kg/bag

Food additives Preservative Natamycin Natamycin CAS:7681-93-8 is almost odorless white to creamy yellow crystalline powder, the crystalline form of natamycin is very stable. Very low solubility in water and most organic solvents. At room temperature, 1 liter of pure water is soluble about 50mg, which is a low solubility ideal for surface treatment of food. When the pH is below 3 or above 9, the solubility of natamycin is greatly improved, but its stability is also decreased. Natamycin has a slightly higher solubility in some organic solvents, such as n-butanol, propylene glycol, etc., but it is necessary to consider whether these solvents can be used in the food produced. Specification: Natamycin   pharma grade  Natamycin  Feed grade Natamycin   Food grade   * Please refer to Certificate of Analysis for lot specific data.  Application: 1) Natamycin is widely used in cheese, meat products, pastries, fruit juices and other foods around the world. The product is refined from Streptomyces natalensis by deep fermentation and multi-step extraction process. The preparation is a mixture of 50% natamycin and 50% lactose. 2) Natamycin  is anti-mildew agent. It has good anti-mildew effect when it is used on the surface of food exposed to air where mildew is easy to prolifze. The use of fermented cheese can selectively inhibit the reproduction of mold and allow the normal growth and metabolism of bacteria.The product should be stored in a well sealed, no direct sunlight, < 15℃. 3) Natamycin is An antifungal polyene antibiotic that inhibits fungal growth by specifically binding to ergosterol. Unlike nystatin and Philippinomycin, natamycin does not alter membrane permeability. Packing: 25kg/drum
