Calcium hydrogen phosphate is commonly used as a food additive and is designated as the food additive code E341 according to the Codex Alimentarius, an international food standards organization. Some common uses and functions of calcium hydrogen phosphate as a food additive include anti-caking agent,calcium supplement,pH regulator,dough conditioner,leavening agent,stabilizer,thickening agent,firming agent,flour treatment agent,dairy products,and so on.

Calcium hydrogen phosphate is used as an anti-caking agent to prevent the formation of lumps or clumps in powdered and granulated food products.It helps maintain the free-flowing properties of the food.

Calcium hydrogen phosphate serves as a calcium supplement in certain food products, contributing to the overall calcium content of the diet. Calcium is an essential mineral for bone health and various physiological functions.

Calcium hydrogen phosphate can function as a pH regulator, helping to control and stabilize the acidity or alkalinity of food products.

In baking, calcium hydrogen phosphate may be used as a dough conditioner to improve the texture and structure of baked goods like bread and cakes.

Calcium hydrogen phosphate can act as a leavening agent in baked goods, contributing to the rise and texture of the final product.

Calcium hydrogen phosphate is used as a stabilizer in certain food formulations to enhance the stability and shelf life of the product.

In some food applications, calcium hydrogen phosphate may act as a thickening agent, contributing to the texture and mouthfeel of the final product.

Calcium hydrogen phosphate may be employed as a firming agent in certain fruits and vegetables to help maintain their texture and prevent softening during processing and storage.

Calcium hydrogen phosphate can be used as a flour treatment agent, improving the properties of flour for baking applications.

Calcium hydrogen phosphate is sometimes added to dairy products to enhance their texture and stability.

The use of calcium hydrogen phosphate and other food additives is regulated by food safety authorities to ensure that they are safe for consumption.The specific applications and permitted levels of use can vary depending on regional regulations and the type of food product.As with any food additive, it is crucial to follow regulatory guidelines and use additives in accordance with good manufacturing practices to ensure food safety and quality.
