Sugar Esters E473, CAS No.37318-31-3 , commonly known as Sucrose esters of fatty acids, manufacturing process by esterifying sucrose with fatty acids. By varying the degree of esterification of the sucrose molecule it is possible to obtain emulsifiers with HLB values ranging from 1 up to 16. It is a light yellow powder, a non-ionic surfactant and is used as an emulsifier in dairy products, baked goods, soft drinks, jelly, cake and candy. Sucrose Fatty Acid Esters are a mixture of mono-, di-, and tri-esters of sucrose with fatty acids derived from edible vegetable or hydrogenated vegetable oils and fats. As an experienced Sugar Esters manufacturer and supplier, we has been supplying and exporting Sugar Esters for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.
