application | calcium phytate has a wide range of uses. In the food industry, the use of a 0.1% concentration of calcium phytate solution for blanching and disinfection can prevent the lid from rusting, so it can be used as an anticorrosive agent; it can also be used as a processing agent for brewing water, alcohol and vinegar products In the fermentation industry, it can replace potassium phosphate when used in the cultivation of wine yeast, so that the yeast can proliferate, the ethanol increases, and the taste is more aromatic; the metal surface is easily electroplated after being treated with calcium phytate solution. |
extraction methods | calcium phytate has many extraction methods, mainly including alcohol precipitation method, heavy metal separation method, dilute acid extraction method, etc. At present, dilute acid extraction is mostly used in industry. That is, the raw material is soaked with dilute inorganic acid, and then neutralized and precipitated with alkali solution to obtain paste calcium phytate product. |
use | as a nutritional medicine, it can promote metabolism, increase appetite and nutrition, and promote development. It is suitable for the treatment of various diseases of the nervous system, as well as vascular hypotonia, hysteria, neurasthenia, rickets, rickets, anemia, tuberculosis, etc. Calcium magnesium phytate is also used to enrich trace amounts of niobium. used as raw material for inositol production mainly used in food, oil, pharmaceutical, feed and other industries biochemical research |
production method | calcium and magnesium phytate can be prepared from corn, industrial calcium phytate or bran quad. Method 1 Put the purified corn into a soaking pot, soak it with 0.3% sulfurous acid solution at 52-53 ℃ for 70h, release the corn soaking solution, add 8 ° B 'e lime milk under stirring, neutralize to pH = 5.4-5.8, let it stand for 1 hour to remove the clear liquid, and the turbid liquid is filtered and dried to obtain calcium and magnesium phytate. The yield of corn was 0.2-0.3%. Method 2 Dissolve industrial calcium phytate in concentrated hydrochloric acid, add activated carbon, and heat to dissolve. Add water to dilute and filter. The filtrate is neutralized with 12% sodium hydroxide solution to pH = 5.1, precipitate pyridine, stand still, and filter. The filter cake is washed with water until the chlorine root meets the requirements, spin it dry, rub it into small strips, ventilate and dry to obtain calcium magnesium phytate, which has a yield of more than 50% to industrial calcium phytate. Method 3: Soak bran curdle with dilute nitric acid for 2h to release phytic acid aqueous solution. The residue is soaked in dilute nitric acid for 5 hours to release phytic acid aqueous solution. Combine the solution and add lime milk to pH = 7. Let it stand and layer, discard the supernatant, filter, spin dry, and dry to obtain crude calcium and magnesium phytate. The yield of dry bran curd is 3-3.5%. |
