Propylene Glycol Esters of Fatty Acids. Source: Manly from plant fat. However, some animal fat contains it as well. For vegetarian purposes the product would indicate the source. In some instances it can be derived from petroleum as well (no associated health risks). Uses (Approved): Emulsifiers and Stabilizers in food. Often found in ice creams and baked goods.
Diethyl ether was then distilled off, and the fatty acid glycol ester was obtained. Preparation of soy oil glycol ester.Each glycol (0.6 mol) was reacted with soybean oil (0.1 mol) in a three-necked ﬂask equipped with magnetic stirrer, thermometer, nitrogen bub- …
Oct 24, 2014· Industrial production of propylene glycol fatty acid esters can take place via the esterification of propylene glycol with fatty acids, typically in the form of commercial stearic acid blends. The use of propylene glycol esters of fatty acids in foods, as with all other food emulsifiers, is controlled by health authorities.
PROPYLENE GLYCOL ESTERS of FATTY ACIDS Prepared at the 49th JECFA (1997), published in FNP 52 Add 5 (1997) superseding specifications prepared at the. 5. ALGINATE 5.1 Alginate production methods 5.1.1 Sodium alginate "Alginate" is the term usually used for the salts of alginic acid, but it can also refer to all the.
Direct esterification is conducted by reacting fatty acids (usually C16/C18) with propylene glycol in the presence of an acid or alkaline catalyst. Product from direct esterification is the mixture of PG monoester and diester. Heating propylene glycol, fat and an alkaline catalyst carries out interesterification.
Propylene glycol esters of fatty acids are mixtures of propylene glycol mono- and diesters of saturated and unsaturated fatty acids derived from edible oils and fats. The products are produced either by direct esterification of propylene glycol with fatty acids or by transesterification of propylene glycol with oils or fats.
