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 Sodium citrate Sodium citrate CAS:68-04-2 , also known as potassium citrate and tripotassium citrate. A citrate with the formula C6H5K3O7 and a molecular weight of 306.39500. It is a white or yellowish crystalline particle or crystalline powder that is odorless, salty, cool, deliquable, soluble in water and almost insoluble in ethanol. Relative density 1.98. Heat to 230 ℃ to melt and decompose. Specification: Sodium citrate  pharma grade Sodium citrate Industrial grade Sodium citrate   Food grade   * Please refer to Certificate of Analysis for lot specific data.  Application: When taking fresh blood clinically, it is necessary to add some disinfected sodium citrate, which can prevent blood clotting, so sodium citrate is called anticoagulant.Used as flavor agent and stabilizer in food and beverage industry; Used as anticoagulant, expectorant and diuretic in the pharmaceutical industry; In detergent industry, it can replace sodium tripolyphosphate as non-toxic detergent additives; It is also used for brewing, injection, photographic medicine and electroplating. It is one of the basic reagents for biological tests. Packing: 25kg/bag

Introduction:  Hexamethyldisiloxane (silicone ether, MM sealing agent) is a colorless and transparent liquid that is prone to deliquescence. Insoluble in water, soluble in various organic solvents. Used as silicone oil, silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, etc. Obtained by hydrolysis of trimethylchlorosilane.  The physical properties of hexamethyldisiloxane  colorless and transparent liquids. Easily deliquescent, flammable, and in contact with high heat, open flames, and strong oxidizing agents, there is a risk of combustion. Boiling point 99.5 ℃. Flash point -1.1 ℃. Relative density (d2525) 0.7606. The refractive index is 1.3750. Insoluble in water, soluble in various organic solvents.  Hexamethyldisiloxane is an important primary organic silicon raw material, often used as a capping agent in the production of silicone oil, or as a cleaning agent for silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, and medical electronic components. The Si O-Si bond in the molecular chain structure of hexamethyldisiloxane has a high chemical bond energy (460 5 kJ/mol), the polysiloxane prepared from it as a sealing agent has good thermal and chemical stability.
