Is esteri dell' 1‚2 propandiolo degli acidi grassi vegan?

Esteri dell' 1‚2 propandiolo degli acidi grassi is an Italian ingredient term that translates to propane-1,2-diol esters of fatty acids, commonly known as food additive E477. This additive functions as an emulsifier and stabilizer, manufactured by chemically reacting propylene glycol with commercial fatty acids. It is widely used in industrially produced baked goods, cake mixes, whipped dessert toppings, shortening, margarine, and ice cream to improve texture and volume.

this additive is possibly vegan because the fatty acids required for its production can be obtained from either plant or animal sources. Plant-derived versions typically use vegetable oils such as palm, soy, or sunflower oil, whereas animal-derived versions use rendered fats such as tallow or lard. Food labels generally do not disclose the origin of the base fats. As a result, consumers must look for an official vegan certification on the packaging or contact the food manufacturer directly to verify the source.
