company news about How to use monoglyceride as emulsifier

Monoglyceride, known as glyceryl monostearate, is an emulsifier widely used in food producing processing, cosmetics and pharmaceuticals. Dihydroxypropyl octadecanoate is chemical name of the product, which is a nonionic surfactant produced by esterification of C16-C18 long-chain fatty acids with glycerol. Monoglyceride not only has good emulsifying, lubricating, fluffing and wetting properties, but also has non-toxic and safe characteristics, so it is widely used in a variety of industrial fields.

Main uses of monoglyceride

Food Industry: Monoglycerides are mainly used as emulsifiers and additives in the food industry, which can effectively prevent the separation of oil and water and improve the texture and taste of food. For example, in candy, chocolate, margarine and ice cream, monoglycerides can prevent the separation of fats and oils and improve the fineness and stability of the products. In addition, in dairy products such as condensed milk, cream of wheat, cheese and instant whole milk powder, monoglycerides can also significantly improve the quick solubility of the product and prevent precipitation and caking.

Cosmetics and pharmaceuticals: In cosmetics, monoglycerides are often used as emulsifiers to make creams fine and smooth. It is widely used in the production of skin creams, cold creams, emulsions, hair milks and other products. In the field of medicine, monoglycerides are also used as emulsifiers in the production of ointments to help the drugs penetrate the skin better.

Plastics Industry: Monoglyceride is used in the plastics industry as an antistatic agent, anti-fogging agent and lubricant. It can lower the electrical resistance of the plastic surface, reduce the formation and accumulation of static electricity, and improve the transparency and sealing performance of films. At the same time, it can also be used as internal and external lubricants to improve the processing performance and yield of plastics.

Usage of monoglyceride as emulsifiers

Monoglycerides are generally more difficult to dissolve directly in water due to their strong lipophilicity, but they can be used in a variety of flexible ways, and suitable methods can be selected according to specific needs.

Mixing with raw material powder: Mix the monoglyceride powder with other raw material powder (e.g. flour, milk powder, etc.) directly and then feed. This method is suitable for the production of some dry-mixed food or cosmetics.

Heating and melting with oil and fat: Melt monoglycerides with oil and fat together, stirring and mixing before feeding. This method is suitable for the products which need fat emulsification, such as margarine, shortening and so on. The heating temperature is usually around 70℃ to ensure that the monoglycerides are fully dissolved and mixed with fats and oils evenly.

Use as a hydrate: Monoglycerides can be slowly dissolved in 4-10 times as much water at 70°C to produce a creamy white paste hydrate when cooled to room temperature. This method can be used to make a hydrate by first heating the monoglyceride to dissolve it into a liquid and then adding it to hot water with high speed agitation. The use of the hydrate cast improves the dispersion and stability of the monoglyceride in water-based products.

Precautions

When using monoglyceride, the appropriate feeding method and amount should be selected according to the process requirements of the specific product and the characteristics of the raw material.

Pay attention to the control of temperature and time during the heating process to avoid the decomposition or deterioration of monoglyceride caused by too high temperature.

Stirring should be sufficient to ensure that the monoglyceride and other raw materials are mixed evenly to achieve the best emulsification effect.

Conclusion

As an excellent emulsifier, monoglyceride plays an important role in food, cosmetic and plastic industries. Through reasonable use and feeding methods, it can give full play to its excellent properties of emulsification, lubrication, fluffing and wetting, and improve product quality and stability. We hope that this article will help us to understand the use of monoglyceride emulsifiers and play a role in practical applications.
