| titleOfInvention | Folic acid stable compound and its preparing method |
| abstract | The invention discloses a folic acid stable compound and a preparation method thereof, wherein the folic acid stable compound comprises the following steps: under the protection of nitrogen, sequentially adding sodium alginate, distilled water and folic acid compounds into a reaction container to be completely dissolved into a solution or form a uniform paste, sucking the solution by a dropper or a needle, moving the solution to a position above the liquid level of a soluble calcium salt aqueous solution, dropwise adding the solution, calcifying for a period of time, and then carrying out vacuum filtration, washing and vacuum drying to obtain the folic acid stable compound. The invention takes sodium alginate and folic acid compounds as raw materials, and the sodium alginate-calcium gluconate compound which is stable under room temperature, illumination and oxygen is obtained by dripping the sodium alginate and the folic acid compounds into soluble calcium salt water solution, so that the folic acid compounds are fixed in the body-shaped reticular structure of the compound and isolated from external oxygen and water, and the problem that the folic acid compounds are unstable in the transportation and storage processes is solved. |
