E422 Glycerol or Glycerin

E422 GLYCEROL OR GLYCERINE

Glycerol means exclusively the pure substance, while there are also derivatives on the market, including glycerine (which contains 95% glycerol).

Glycerol, synthesized for the first time in 1779 by Carl Scheele, is a natural organic compound, in whose structure there are three groups –OH; thanks to this chemical characteristic, glycerol is miscible with water in all its parts. Glycerol is both a component of lipids (being normally present in fats and oils) and phospholipids. When the body uses its own fat reserves, it first breaks it down into fatty acids and glycerol, then later on, at the liver level, it transforms glycerol into glucose, then converting it into a fundamental energy source for cell metabolism.

In foods, glycerol has a sweetening, humectant, emulsifying and support function for synthetic additives.

The product, industrially obtained as a by-product of soap processing, is used in the food field as an additive (with the abbreviation E422); it can be found in numerous products, such as candies, aromas, liqueurs, syrups, bakery and pastry products, dietary foods, etc.

At high doses, glycerol may cause nausea and / or migraine headaches, thirst and high blood pressure.
