Description of Polyglyceryl-3-stearate: What you need to know  :

Chemical composition

The esterification of polyglycerine and stearic acid synthesizes polyglycerin-3 stearate. Polyglycerol is a compound polymerized from glycerol (glycerol), usually consisting of 3 to 10 molecules. Stearic acid is octadecanoic acid, a common saturated fatty acid. In polyglycerol-3 stearate, the molecular chain length, polymerization degree and esterification degree of polyglycerol and stearic acid will affect their properties.

Physical properties

Appearance and form: Polyglycerol-3 stearate is a white or light yellow powder or particle, hygroscopic, soluble in water and oil.

Melting point and boiling point: Due to its chemical composition and molecular structure, polyglycerol-3 stearate has a high melting point and boiling point, generally around 200 ° C.

Solubility: It has good solubility in water and organic solvents, making it well dispersed in food processing water and oil phases.

Viscosity: The viscosity of polyglycerol-3 stearate decreases with the increase in temperature, which helps to improve the texture and taste of food.

Chemical properties

Stability: Polyglycerol-3 stearate has a certain stability under acid, alkali, heat and other conditions, and hydrolysis or oxidation reactions are not easy. This allows it to maintain good stability during food processing and storage.

Emulsification: polyglycerol-3 stearate has good emulsification performance, which can reduce the interfacial tension of oil and water and promote the uniform dispersion of the oil and water phases. This property makes it used as an emulsifier in dairy products, beverages, ice cream and other foods.

Thickening: Polyglycerol-3 stearate has a thickening effect, which can increase the viscosity and consistency of food and improve its taste and texture. It can be used as a stabilizer and thickener in yogurt, jams, salad dressings, and other foods.

Antioxidant: Polyglycerol-3 stearate has certain antioxidant properties, which can delay the process of food oxidation and deterioration and extend the shelf life of food.

Security

Polyglycerin-3 stearate has been widely used in the food industry and is considered a safe food additive. However, further research is needed on the effects of long-term intake on human health. Polyglycerin-3 stearate should be operated strictly with relevant regulations and standards to control the amount of use and residue in food.

Applications of Polyglyceryl 3 stearate  :

Dairy product field

Dairy products are one of the important applications of polyglycerol-3 stearate. In the production process of yogurt, cheese, butter, and other dairy products, polyglycerol-3 stearate can be used as an emulsifier and stabilizer to improve the product's stability, taste, and texture. It can reduce the interfacial tension of oil and water, promote the uniform dispersion of oil and water phase, and prevent emulsion separation and precipitation so that the product can maintain consistent quality during the shelf life.

Beverage field

Beverages are another important area for polyglycerin-3 stearate applications. In the production process of fruit juice drinks, tea drinks, coffee drinks, etc., polyglycerol-3 stearate can be used as an emulsifier and dispersant to improve the stability of the product, prevent oil-water separation and suspended particle precipitation so that the product can maintain a uniform appearance and taste during the shelf life. In addition, polyglycerol-3 stearate can also be used in carbonated beverages to improve the stability of bubbles and delay the time of bubble disappearance.

Ice cream field

Ice cream is another area where polyglycerin-3 stearates are used. It can improve the fineness, lubricity, and stability of the ice cream, prevent the formation of ice crystals, and separate the emulsion so that the ice cream can maintain good quality during shelf life. At the same time, polyglycerin-3 stearate can also be used to produce low-sugar, low-fat ice cream to meet consumer demand for healthy food.

Baked goods

Polyglycerin-3 stearate is also widely used in the field of baked goods. In the production process of baked goods such as cakes and cookies, polyglycerol-3 stearate can be used as a softener and emulsifier to improve the texture and taste of dough and the freshness and shelf life of products. It can enhance gluten's elasticity, improve dough's flexibility and operability, and make baked goods more delicate, soft and delicious.

Canned food field

Canned food is another area where polyglycerin-3 stearate is used. In the production process of canned food, polyglycerol-3 stearate can be used as an antioxidant and stabilizer to improve the stability and antioxidant properties of the product. In addition, polyglycerol-3 stearate can also be used in the cooking and sterilization process of canned food to improve the product's thermal stability and cooking resistance.

Nutrition and health products

With people's increasing attention to healthy diets, the nutrition and health products market is also booming. Polyglycerin-3 stearate, as a safe food additive, is also widely used in nutrition and health products. It can be used as a carrier, soft capsule wall material, and other components for producing nutritional supplements, vitamin supplements, fish oil, and other health products. At the same time, because polyglycerol-3 stearate has good stability, solubility, and biocompatibility, it is also used to produce some special-purpose nutritional health products, such as specific health products for athletes, older people, and children.

Production Method of Polyglyceryl 3 stearate  :

Esterification process

Esterification is the most commonly used method in the industrial production of polyglycerol-3 stearate. The method is to esterify polyglycerol and stearic acid under the action of a catalyst to produce polyglycerol-3 stearate. The advantages of esterification are a mature process, high yield, and stable product quality. However, the esterification method needs to use a large amount of organic solvents, and the reaction conditions are relatively intense, which requires high equipment and will produce certain environmental pollution. 

Transesterification method

Transesterification is an environmentally friendly production method; through the transesterification reaction, polyglycerol and fatty acid glycerol ester are exchanged to produce polyglycerol-3 stearate.  However, the reaction yield of the transesterification method is low, requires the use of a large number of raw materials, and the product quality is not easy to control. Therefore, the transesterification method is mainly suitable for small-scale or special-purpose production.

Enzymatic method

The enzymatic method is a biocatalytic production method that esterifies polyglycerol and fatty acids through an enzymatic reaction to produce polyglycerol-3 stearate. The enzymatic method has the advantages of high selectivity, high conversion, and high product, while the specificity and regulation of enzymes make the product quality easy to control. In addition, enzymatic reaction conditions are mild, can be carried out at room temperature and pressure, and are environmentally friendly. However, the production cost of the enzyme method is higher than the cost of enzyme preparation and recovery. Therefore, the enzymatic method is mainly suitable for laboratory or pilot production stages and has not been widely used in industrial production.

In actual production, the choice of production method also needs to consider raw material sources, production scale, equipment investment, environmental protection, and other factors. Esterification has been widely used in industrial production because of its mature and stable process and high yield. These new technologies can improve reaction efficiency and yield while reducing the use of organic solvents and waste generation.
