1,2-Dilinoleoyl-3-palmitoyl-rac-glycerol is a triacylglycerol that contains linoleic acid at the sn-1 and sn-2 positions and palmitic acid at the sn-3 position. It has been found in a variety of vegetable oils, including poppy seed, hazelnut, maize, and olive oils.1 1,2-Dilinoleoyl-3-palmitoyl-rac-glycerol (3% w/v) reduces scald development on apples of the Delicious variety when applied immediately following harvest and assessed after six months of storage.2
