Have you ever observed the labels on packaged products? If you did, you probably noticed that there would be a lot of food additives there. One of these is an emulsifier known as propylene glycol monostearate. Do why they are in foods and what they do in foods. In this post, we are going to take an in-depth look at the applications of PGMS emulsifier e477 in food.
What is Propylene Glycol Monostearate?
Propylene glycol monostearate (PGMS) is a food additive derived from propylene glycol and stearic acid. PGMS emulsifier e-number is 477. Its excellent foaming, stabilizing, and emulsifying properties explain why it is often found in many packaged products. Besides, PGMS emulsifier is often blended with other emulsifiers to achieve better synergistic effects. Propylene glycol fatty acid ester is often employed as an emulsifier and foaming agent in shortening, margarine, ice cream, and a large number of bakery products.
What is Propylene Glycol Monostearate Derived From?
Emulsifier 477 is produced by mixing and heating propylene glycol and stearic acid to react with each other, and then goes through a series of filtration and distillation processes. Purified PGMS emulsifier is free of impurities and can be used in a wide range of industries, including food, personal care products and pharmaceuticals.
What is Propylene Glycol Monostearate Used for?
With a clearer overview of the components of the Propylene Glycol Monostearate (PGMS) now, a more detailed exploration of its common uses in food is in order.
Bread and pastry
Propylene glycol fatty acid ester is widespread in bakeries. E477 emulsifier is usually incorporated into the dough of many bread makers. This is because it can prevent moisture loss and has the ability to improve the consistency and texture of the dough when added to bread recipes. When used in shortening, PGMS emulsifier 477 is also beneficial in preventing the aging of breads and baked products, giving them a superior appearance and flavor.
PGMS emulsifier works as cake emulsifiers anti-caking agents, and antioxidants. Propylene Glycol Monostearate can be applied in the cake-making process to increase the volume of the cake and keep the sponge foam uniform, thus giving the cake a fine texture and taste and extending its shelf life. PGMS emulsifiers are usually added to cakes with DMG, Span60 and PGE.
If PGMS emulsifier is used for whipping cream, it is helpful to shorten the whipping time and improve the volume and structure of the foam. Also, propylene glycol monostearate is beneficial in the creation of a nice, firm foam, thus improving the mouthfeel and quality of the cream. PGMS emulsifier is often combined with DMG and Span60. Ice-cream
Propylene Glycol Monostearate is also found in ice cream formulations. The presence of PGMS emulsifier in ice cream helps to improve the expansion of the ice cream and prevents the formation of large crystals. Better emulsification can be achieved when used in combination with DMG.
Propylene Glycol Monostearate VS Propylene Glycol
Propylene Glycol Monostearate is a white powder or waxy solid. PGMS e477 is a propylene glycol monoester, which is an emulsifier produced by the esterification of fatty acids combined with propylene glycol. Emulsifier e477 is a combination of mono- and diesters. Propylene glycol fatty acid ester is an oil-soluble emulsifier with remarkable foaming properties allowing it to be utilized as a foaming agent in cakes and pastries.
Propylene glycol e1520 is a colorless, thick liquid that is hygroscopic. Propylene glycol C3H8O2 is manufactured by the hydration of propylene oxide. It is often used as a food additive with the chemical formula C3H8O2 and the E-code E1520. Propylene glycol additives are often used in many packaged food products, including condiments, breads, food colorings, and dairy products. Propylene glycol for sale is beneficial in improving the texture and flavor of products and extending their shelf life.
In general, the striking emulsifying and foaming properties of Propylene glycol fatty acid ester have made it a valuable food additive for diverse industries.
