Introduction of food additive trimagnesium phosphate.
Trimagnesium phosphate, also known as magnesium phosphate, is a white or yellowish powder that is widely used in food, medicine, and cosmetics. As a food additive, trimagnesium phosphate has many excellent properties, which will be described in detail in this article.
1. Composition and properties of trimagnesium phosphate.
Trimagnesium phosphate is formed by combining phosphate ions with magnesium ions and is an inorganic salt additive. Its molecular formula is Mg3(PO4)2 and its relative molecular weight is 36088。Trimagnesium phosphate is a white or yellowish powder, hygroscopic, soluble in acid and alkali solutions, and slightly soluble in water. In air, trimagnesium phosphate is easily deliquescent to form magnesium diphosphate and magnesium hydroxide.
2. The use of trimagnesium phosphate.
1.Food additives.
Trimagnesium phosphate is widely used as a food additive in a variety of foods, such as dairy products, bread, biscuits, etc. In dairy products, trimagnesium phosphate can act as a stabilizer to improve the stability of the product and prevent product separation and precipitation. In bread and biscuits, trimagnesium phosphate can be used as a improver to improve the taste and appearance of the product.
2.Pharmaceutical raw materials.
Trimagnesium phosphate is also used as a raw material for pharmaceuticals, such as in the production of antacids, antispasmodics, etc. Its antacid effect can relieve stomach pain, ** stomach ulcer and other diseases.
3.Cosmetic ingredients.
In cosmetics, trimagnesium phosphate can be used as a humectant, antiallergy and antibacterial agent, among other things. It effectively locks in moisture, keeps it moist, relieves allergy symptoms, and has an antibacterial effect that helps to maintain health.
3. The safety of trimagnesium phosphate.
Trimagnesium phosphate is safe to use in normal doses. However, excessive intake may cause some unpleasant symptoms such as nausea, vomiting, and diarrhea. Therefore, when using trimagnesium phosphate as a food additive, it should be added in strict accordance with the standards stipulated by the state to ensure the health and safety of consumers.
Fourth, the production method of trimagnesium phosphate.
1.Metathesis.
Magnesium oxide and phosphoric acid are metathesis to obtain trimagnesium phosphate. The specific steps are as follows: add magnesium oxide to an appropriate amount of water, heat and stir until dissolved; Phosphoric acid solution was added to adjust the pH value to the specified range; After the reaction is completed, the trimagnesium phosphate product can be obtained by filtration, washing and drying.
2.Precipitation method.
The soluble magnesium salt is reacted with phosphoric acid to form phosphate precipitate, which is then heated and decomposed to obtain trimagnesium phosphate. The specific steps are as follows: the soluble magnesium salt solution is added to the excess dilute phosphoric acid solution, and the pH value is adjusted to the specified range; After the reaction is completed, filtration, washing, and drying are carried out; The obtained solid matter can be heated and decomposed to obtain trimagnesium phosphate product.
5. ConclusionIn general, as an important inorganic salt additive, trimagnesium phosphate has a wide range of application prospects in the fields of food, medicine and cosmetics. Knowledge of its composition, properties, uses and production methods can help to make better use of this substance. In the process of use, it should be added and used in strict accordance with the standards stipulated by the state to ensure the health and safety of consumers. Nutritional fortifiers
