What is Glyceryl Monostearate?
Glyceryl monostearate is an organic compound with a white powder appearance. It is primarily used as an antioxidant, stabilizer, and emulsifier in the food industry. It improves the emulsification of oil and water, enhances dough stability, improves the volume and texture of food, and prolongs the shelf life of food to ensure the consistency and freshness of food.
It is frequently used to enhance flavor and preserve consistency in baked goods including bread, cakes, and biscuits.
The preparation process of Glyceryl Monostearate in China mainly includes chemical synthesis, esterification reaction and hydrogenation. Among them, chemical synthesis is the most mainstream production process. It generates monostearate glycerol by heating stearic acid and glycerol under the action of a catalyst. After the reaction, the product is purified by neutralization, washing, cooling crystallization or distillation to ensure that high-purity Glyceryl Monostearate is obtained.
The esterification reaction method is also commonly used to prepare Glyceryl Monostearate. This method esterifies stearic acid and glycerol under the action of an appropriate catalyst, and controls the reaction temperature and pressure to improve the reaction efficiency. After the reaction, the product is cooled and filtered to get rid of byproducts and unreacted source ingredients to create the desired food-grade product.
Hydrogenation is mainly used to produce Glyceryl Monostearate with specific properties. This process involves hydrogenating stearic acid and then esterifying it. Although this method is less used, it can still provide the desired product properties for specific applications. The final product also needs to be separated and purified.

Ginger Powder has a wide range of uses
- Emulsification: GMS combines water and oil to form a stable emulsion and functions effectively as an emulsifier.
This emulsification is essential for the uniformity and stability of many foods. For example, in condiments, sauces, ice cream and other products, GMS can prevent oil and water from stratifying and make the texture of the final product more uniform. - Improve food texture: In baked foods, GMS can improve the stability and gas retention of dough, thereby improving the volume and texture of food. For example, it can make baked products such as bread and cakes softer and more delicate, reducing hardening and drying.
- Increase food stability: GMS can delay the oxidation of fats and oils in foods, thereby extending the shelf life of foods and maintaining the flavor and nutritional value of foods. It plays a stabilizing role in some high-fat foods, preventing oil decomposition and deterioration.
- Improve processing performance: In food processing, GMS can improve the efficiency of mixing and stirring and improve the smoothness of the production process. For example, adding GMS during production can reduce the adhesion of ingredients and simplify equipment cleaning.
User asked question:
Q: Does Glyceryl Monostearate cause any effects on the skin?
A: In general, Glyceryl Monostearate (GMS) is safe for skin use and has no adverse effects. This chemical is frequently used in food, cosmetics, and skin care products as an emulsifier and stabilizer; allergic responses or skin irritation are unusual side effects.
However, a very small number of people may experience mild irritation or allergic reactions to GMS or other ingredients, which is usually related to individual skin sensitivity.
Overall, GMS has a high skin safety rating and most people will not encounter problems when using products containing GMS. To make sure there are no negative reactions, a local test should be done before usage for those with extremely sensitive skin or a history of allergies. If you experience any discomfort, you should cease using it right away and see a medical expert.
