Disodium stannous citrate;Sodium stannous citrate

Product Categories:

Reducing agents; stabilizers and coagulants; food additives; food and feed preservatives; food and feed additives; canned mushrooms, fruits and vegetables;

Chemical Properties:
  1. Stannous citrate is a white crystalline powder. Easily deliquescent, easily soluble in water, and easily oxidized.
  2. Stannous citrate disodium stannous citrate has anti-oxidation, color protection, and low toxicity. Its color protection effect is better than common color retention agents such as citric acid, ascorbic acid, sodium erythorbate, and the effect is equivalent to that of sulfite. At present, the research on the color protection effect of disodium stannous citrate is mainly focused on canned fruit and vegetable products, but there is no research report on the color protection of olive juice.
  3. Stannous citrate is a new type of color retention agent, which has strong reducibility, anti-oxidation, anti-corrosion, and color protection effects, and its toxicity is lower than that of sulfites. It can eliminate oxygen in the environment and block the oxidative corruption of food caused by air oxidation, thereby playing an anti-oxidant and color protection effect, maintaining the color, quality and flavor of food
  4. Stannous citrate has been widely used in mushrooms, lotus roots, and lemons. Color protection processing of canned fruits and vegetables such as green plum, etc. (Jin Dingliang, 200Chemicalbook 9). Jin Dingliang and Xia Wenshui (2011) studied the color-protecting effect of disodium stannous citrate on fresh-cut lotus roots, and treated them with 0.05%~0.2% disodium stannous citrate soaking solution for 15 minutes at pH 3~6, ​​and then fresh-cut lotus root products It can maintain a low degree of browning and polyphenol oxidase activity. Zhang Tingting et al. (2013) studied the color protection effect of disodium stannous citrate on canned Agaricus bisporus. In the pretreatment stage, disodium stannous citrate has better inhibition on enzymatic browning of Agaricus bisporus than phytic acid, citric acid and VC. effect. Disodium stannous citrate has a good color protection and anti-browning effect on olive juice. The light transmittance of the juice is 91.7%. Disodium stannous citrate can effectively protect the original color of olive juice, which may be related to the metal in it. Copper ions chelate and make enzymes inactivated.
  1. Stannous citrate is a reducing agent with anti-oxidation, color protection and antiseptic effects. my country stipulates that it can be used for canned fruits and vegetables, mushrooms, and the maximum use amount is 0.3g/kg. Use reducing agent; color protection agent; anti-corrosion agent. Uses: Used as an antioxidant preservative for edible fungi, fruits, and canned fruit. The production method is to generate distannic citrate from citric acid, stannous chloride and sodium hydroxide, and then react with sodium hydroxide and citric acid Chemicalbook to obtain The disodium stannous citrate solution is vacuum-concentrated, filtered to remove the insoluble matter, and then vacuum-dried. Production method First dissolve citric acid and stannous chloride in distilled water, add sodium hydroxide while stirring, and filter to obtain a distannic citrate solution; then add citric acid to obtain stannous citrate; then add sodium hydroxide to neutralize it.
  2. Stannous citrate finally concentrated in a vacuum, filtered to remove insoluble matter, and vacuum dried to obtain a finished product.
