Processed
Propylene Glycol
Propylene glycol is a clear, slightly sweet, low-viscosity polyol used in foods as a humectant, solvent for flavours, colours, and some extracts, and as a carrier that keeps soft products pliable. Food-grade material is highly purified and distinct from industrial antifreeze formulations that may contain other glycols or denaturants. It holds moisture with less stickiness than heavy glycerol doses and dissolves many oil-soluble aroma compounds better than water alone. Overuse can leave a faintly chemical or warming aftertaste. Typical culinary contact is via commercial flavourings rather than bulk kitchen bottles. Always specify food-grade USP/FCC material when formulating.
Also known as: E1520, Propane-1,2-diol (E1520), Propylene glycol, PG food grade, Puropiren gurikoru

History
Propylene glycol was first prepared in laboratory organic synthesis.
Commercial production supplied solvents and early food and pharmaceutical carriers.
Flavour houses adopted propylene glycol as a standard extract and colour solvent.
Global food additive approvals clarified purity grades for humectant and carrier use.
