A procedure is described for the separation, identification, and quantitative estimation of propylene glycol mono‐ and diesters of lauric, myristic, palmitic, stearic, and oleic acids in shortenings and lard containing mono‐ and diglycerides. Lipid classes are separated on a silicic acid column, and individual esters are estimated by gas chromatography. Analyses of several control mixtures and commercial samples are reported. Recoveries for individual components range from 92 to 105%, and total recoveries range from 96 to 100%.
