Food fortifier of zinc glycine
摘要：Food fortifier of zinc glycine
Zinc Glycine
Zinc Glycinate
Coding GB16.000
Traits white flake or granular powder, soluble in water, insoluble in ethanol, the melting point of 290 ° C, and good stability. This product is zinc content of 31.8%.
Method by glycine, zinc oxide in an alkaline reaction, purified extract obtained.
Quality standards
Methods of identification
1. Zinc ion reaction to take the product solution (1 +10), the Gaja ferricyanide reagent produce a white precipitate. The precipitated insoluble in dilute hydrochloric acid.
2. Take a solution of 5 ml of the goods (1 +10), add 5 drops of dilute hydrochloric acid, and 5 drops of sodium nitrite reagent (1 +2), which produce a colorless gas.
3. Take the 2mL this product solution (1 +10), add 1mL ferric chloride test solution was red, add an excess of dilute hydrochloric acid, the red color disappeared, add excess strong lye, red reproducing.
4. Take the 2mL This product solution (1 +10), add 1 drop of liquid phenol and 5mL sodium hypochlorite reagents blue.
Toxicology basis
1. LD50 the rat oral 1.71g/kg weight (1.05 to 2.78) (female);
Rats the oral 1.26g/kg weight (0.775 to 2.05) (male).
Rats the oral 2.00g/kg weight (1.37 to 2.9) (female);
The rat oral 2.33g/kg weight (1.43 to 3.7) (male).
2. Mutagenicity test Ames test, mouse chromosome aberration test were negative
Using Zinc enhancer.
The use and the use of "food additives health standards" (GB 2920-1996) nutrition fortifier new varieties to use the scope and use of the provisions: can be used to strengthen zinc drinks, cereals and their products, the amount of 10 ~ 20mg/kg ; used in the dairy, dosage of 30 ~~ 60mg/kg; formula for infants, a dosage of 25 ~ 27mg/kg.
