Glycerol esters are compounds formed by the reaction of glycerol, a simple sugar alcohol, with fatty acids. These esters are commonly found in nature and are used in various applications, including food, cosmetics, and pharmaceuticals. They serve as emulsifiers, helping to blend ingredients that typically do not mix, such as oil and water. In the food industry, glycerol esters, like monoglycerides and diglycerides, are often added to improve texture and extend shelf life. In cosmetics, they help to stabilize formulations and enhance skin feel. Overall, glycerol esters play a vital role in many products we use daily.
