Applications

Trimagnesium PhosphateMineral Supplement: Trimagnesium phosphate serves as a source of essential minerals in food. Magnesium and phosphorus are important for various physiological functions in the human body, including bone health, energy metabolism, and nerve function.

Anticaking Agent: Trimagnesium phosphate may also be used as an anticaking agent to prevent clumping or agglomeration in powdered or granulated food products. It helps to improve the flowability and dispersibility of such products.

Cheese Production: In cheese manufacturing, trimagnesium phosphate can be utilized as a coagulant. It aids in the curdling process by helping to separate milk proteins and facilitate the formation of the cheese curd.

Baking Applications: Trimagnesium phosphate can be added to baking mixes or doughs as a leavening agent. It reacts with other ingredients, such as baking soda or baking powder, to release carbon dioxide gas, resulting in the expansion and rising of baked goods.

Emulsifier Stabilizer: Trimagnesium phosphate can act as an emulsifier and stabilizer in certain food products. It helps to improve the stability and texture of emulsions, such as salad dressings or mayonnaise, by preventing separation or phase separation between oil and water components.

pH Control in Beverages: In some beverages, trimagnesium phosphate may be used to adjust and control the pH level. It can help maintain the desired acidity or alkalinity of the beverage, enhancing its flavor and stability.

Nutritional Supplements: Trimagnesium phosphate is sometimes incorporated into nutritional supplements, such as vitamin and mineral formulations, to provide a source of magnesium and phosphorus. These supplements aim to support overall nutritional balance and provide essential minerals to the body.

Yeast Nutrient: In certain fermented food and beverage products, trimagnesium phosphate can serve as a nutrient for yeast. It helps to promote yeast growth and fermentation, contributing to the desired flavors, textures, and carbonation in the final product.

Dairy Alternative Products: Trimagnesium phosphate may be used in dairy alternative products, such as plant-based cheeses or yogurts. It can assist in the texture and structure development of these products, mimicking the properties of dairy-based counterparts.
