  • Fatty acid ester - Wikipedia

    Fatty acid esters (FAEs) are a type of ester that result from the combination of a fatty acid with an alcohol. When the alcohol component is glycerol, the fatty acid esters produced can be monoglycerides, diglycerides, or triglycerides. Dietary fats are chemically triglycerides.

  • Improved synthesis of sucrose fatty acid monoesters

    ABSTRACT: The base-catalyzed synthesis of four sucrose fatty acid esters (caprylate, laurate, myristate, and palmitate) was per-formed in dimethylsulfoxide by transesterification of sucrose with the corresponding vinyl esters using disodium hydrogen phosphate as catalyst. In using a molar ratio sucrose/vinyl ester

  • Evaluation of Sucrose Fatty Acid Esters as Lubricants in ...

    Sucrose fatty acid ester (SE) is a compound formed from sucrose and fatty acids. It is a nonionic amphiphilic substance that varies in hydrophile–lipophile balance (HLB) depending on the degree of fatty acid substitution in its structure. Owing to the broad range of possible HLB values, SEs are used as food additives, among several other uses.

    Because most fats have 3 fatty acids bonded to glycerol with 2 oyxgen atoms in each "ester" bond, the molecular formula is probably C 54 H 108 O 6. This molecule would contain the 3 carbon glycerol backbone, the 3 fatty acid chains would share the remaining 51 carbon atoms, and would be of average length 51/3 = 17 carbon atoms.

  • The use of sucrose esters of fatty acids as a food additive

    The new manufacturing method results in residues of vinyl esters of fatty acids of <10-111 mg/kg and acetaldehyde of 20-48 mg/kg in the sucrose esters of fatty acids. p-Methoxyphenol was undetectable. The vinyl portion of the vinyl ester instantly tautomerises to acetaldehyde in the gastrointestinal tract.

  • Sucrose esters, specialty emulsifiers - New Food Magazine

    Sucrose esters of fatty acids, commonly known as sucrose esters (E473), are a special type of emulsifiers. Sucrose esters have several benefits besides emulsification, such as starch interaction, protein protection, sugar crystallisation and aeration.

  • Sucrose esters - Wikipedia

    Sucrose esters. The polar sucrose moiety serves as a hydrophilic end of the molecule, while the long fatty acid chain serves as a lipophilic end of the molecule. Due to this amphipathic property, sucrose esters act as emulsifiers; i.e., they have the ability to bind both water and oil simultaneously.
