Sodium Metabisulfite Fcc/photo Grade

Sodium metabisulfite is white or yellow crystalline powder or small crystal, with a strong SO2 odor, soluble in water, the aqueous solution is acidic, when contacted with strong acid, SO2 is released to form corresponding salts, and it is oxidized to Na2S2O6 when placed in the air for a long time. Therefore, the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.

Sodium Erythorbate FCC Grade is mainly used in food industry, it is used as an food additive and antioxidant in a broad range of foods like meat, fish, beer, fruit juice, syrup crystal, canned fruit and vegetable , nutritional supplients,cake, dairy products, soft drinks ,sherry,wines, pickles, and grease etc. In processed meats, such as hot dogs and beef sticks, it increases the rate at which nitrite reduces to nitric oxide, aiding in a faster cure and retaining coloring. As an antioxidant, it helps improve flavor stability and stops the formation of carcinogenic nitrosamines. Sodium Erythorbate FCC grade is also used as an ingredient in personal care products, it is primarily used in hair and nail products, functioning as an antioxidant. The FCC grade meets the requirements of the Food Chemical Codex indicates and is suitable for all food, beverage and nutritional supplement applications.

White powder or tiny crystals, inodorous and salty, easily soluble in water, insoluble in alcohol, presenting slightly alkalinity, decomposed when heating. Decomposed slowly when exposed to moist air. Natural soda is firstly dissolved into solution (Na2CO3) and filtrated. The clear solution is then fed to carbonizing tower ; accordingly, CO2 is compressed and bubbled up from the bottom of the tower, After carbonization, the slurry will be flowed from the bottom and separated. Dried to the finished product. Usage: Used as food fermentation, detergent ingredient, carbondoxide foamer, pharmacy, leather, ore milling and metallurgy, detergent for wool, exiting usher and metal heat-treating, fiber and rubber industry, etc.
