Detection of 1-Monoglycerides in the Fat From Rancid Milk

Abstract
Ether extracts of fat from rancid milk were partitioned between heptane, and 80% ethanol. Two samples of the 80% ethanol soluble fraction contained 60.48% and 54.17% 1-monoglycerides respectively as determined by periodic acid oxidation. Infrared absorption spectra measurements of the fractions showed spectra characteristic of monoglycerides.
