glycerol A trihydric alcohol, chemically 1,2,3‐propane triol (CH2OHCHOHCH2OH), also known as glycerine. Simple or neutral fats are esters of glycerol with three molecules of fatty acid, i.e. triacylglycerols, sometimes known as triglycerides. See also glycerides.

Glycerol is a colourless, odourless, viscous liquid, sweet to taste; it is made from fats by alkaline hydrolysis (saponification). Used as a solvent for flavours, as a humectant to keep foods moist, and in cake batters to improve texture and slow staling.
