Abstract
Lipids were extracted from the food sample with petroleum ether and su crose polyesters (SPE) and triglycerides in the extract were hydrolyze d with 1N methanolic KOH for 8 min. Free sucrose was extracted with wa ter, and quantified colorimetrically using a phenol-sulfuric acid test . Results were compared to a standard curve from known quantities of h ydrolyzed SPE. Standard curves were linear and reproducible through 90 % SPE (r = 0.999).
