In the modern food processing industry, the application of food additives has become an important means of ensuring food quality and improving food taste. Magnesium stearate, a commonly used food additive, plays an indispensable role in the food industry due to its unique physical and chemical properties.

　　Magnesium stearate food additive is a white, non-sandy fine powder with a slight odor and a slippery feel when in contact with skin. It is insoluble in water, ethanol, and ether, but soluble in hot water and hot ethanol. When encountering acids, magnesium stearate decomposes into stearic acid and the corresponding magnesium salt. These properties give magnesium stearate unique advantages in food processing.

　　In the food industry, magnesium stearate food additive is mainly used as an emulsifier, anti-caking agent, and coating agent. It is widely used in the production and processing of foods such as candies, candied fruit, cakes, chewing gum, and some dairy products. By adding magnesium stearate, food can achieve better taste and appearance while extending shelf life.

　　According to the national standard GB1886.91—2016, magnesium stearate food additive is a food additive refined from the combination of magnesium oxide and edible solid mixed fatty acids (mainly stearic acid). Under normal use, magnesium stearate is safe and will not harm the human body. Some people may be allergic to magnesium stearate and may experience allergic reactions after ingestion. Long-term and large amounts of magnesium stearate ingestion may also irritate the gastrointestinal tract, affecting human health.

　　To ensure food safety, China implements a strict regulatory system for food additives. When using food additives such as magnesium stearate, food operators must follow relevant regulations and standards to ensure the safe and compliant use of food additives. At the same time, food regulatory authorities will regularly conduct random inspections and monitoring of food additives to ensure that food quality meets national standards.

　　In summary, magnesium stearate food additive has broad application prospects and an important role in the food industry. On the premise of ensuring food safety, the reasonable use of food additives such as magnesium stearate can improve food quality and taste, meeting consumer needs.
