This product is light khaki crystalline powder, stable in nature and unchanged for a long time, and easily soluble in water and acid. Iron EDTA (pre-iron), scientific name NaFe-EDTA, molecular formula C 10H 12FeN2NaO8? 3H2O with a molecular weight of 42 1.09. 1995, the Joint Expert Committee of WHO/FAO suggested that the Nutrition Committee of WHO/FAO Pharmacopoeia should take sodium ferric EDTA as a new nutritional additive.
Approved by the Ministry of Health of China, ferric EDTA has been listed as a nutritional fortifier in China, and has applied for the national invention patent. Sodium ferric EDTA is a new type of high-efficiency blood-enriching iron fortifier.
As an iron nutritional supplement, compared with other iron salts, it has the following outstanding advantages:
High-efficiency absorption, the absorption rate is 2-3 times that of the traditional iron nutritional fortifier, the taste is good, and there is no rust smell;
It belongs to compound iron agent and has no gastrointestinal irritation;
Does not affect the sensory quality of food;
Will not cause food oxidation, and can prolong the shelf life of iron fortified food;
Does not affect the absorption of other mineral elements and trace elements;
[Applicable function]
1. Promote lead discharge;
2. Improve nutritional anemia;
3. Nutritional fortifier;
4.EDTA- iron should not be used as the source of nutritional supplement-iron;
note:
Because EDTA- ferric sodium is a strong chelating agent, it can complex other divalent cations in the body and interfere with divalent cation-dependent enzymes, and the compatibility of EDTA- ferric sodium with traditional Chinese medicine lacks scientific literature support. According to the available data, experts in health food evaluation are still controversial about its edible safety. Therefore, the following points should be paid attention to when declaring such products at present:
1 and EDTA- iron are not suitable as iron sources as nutritional supplements;
2. Application function: Health food with ferric EDTA as raw material. The application of health care function is temporarily limited to promoting lead excretion and improving nutritional anemia;
3. Dosage: According to the Hygienic Standard for the Use of Food Nutrition Fortifiers (GB 14880), the daily intake of EDTA-iron for adults should not exceed 92mg (converted into iron 12 mg), and children should be halved;
4. In view of the unclear mechanism of compatibility between EDTA- iron and traditional Chinese medicine, in principle, it is not recommended that EDTA- iron be compatible with traditional Chinese medicine (except raw materials with blood-enriching function such as donkey-hide gelatin and red dates).
