Summary The monoglycerides from eight samples of lipolyzed milk fat were converted to allyl esters and identified by gas-liquid chromatography. Fresh milk fat did not contain monoglycerides detectable by the methods used. The majority of the samples

Summary Two symmetrical triglycerides, 2-oleoyl dipalmitin and 2-palmitoyl diolein, were synthesized and then subjected to hydrolysis at pH 6.6 by milk lipase. The results indicate that milk lipases preferentially hydrolyze the primary hydroxyl ester

Summary The average interfacial tensions (in dynes per centimeter) of control and lipolyzed milk fat-water systems were, respectively: extracted fat—5.4, 4.0, af ter removal of free fatty acids—5.9, 2.7, after removal of acetone insoluble lipids

Summary The average total monoglyceride contents of several dairy products reported as m M /100g. of fat were: fresh, raw milk—0.077; pasteurized whole milk—0.145; homogenized milk—0.206; 40% cream—0.119; butter—0.189; and Blue cheese—0.3

Summary The glyceride and fatty acid compositions of 20 commercial ice cream emulsifiers were determined. The ranges of mono-, di-, and triglycerides were 20.6–93.5%, 6.5–51.3%, and 0.5–16.6%, respectively. Glyceride contents were determined co

Summary The milk from ten Holsteins was analyzed for initial acid degree value (ADV), spontaneous lipolysis, and induced lipolysis during a 3-mo. switch-back feeding trial involving two winter rations and a 10-wk. cross-over feeding trial involving a

Summary A method for the analysis of milk fatty acids, employing separation of methyl and butyl esters by gas-liquid chromatography (GLC), has been developed. The methyl esters were separated on a diethylene glycol succinate (DEGS) column and the but

Summary The diglycerides in eight samples of lipolyzed milk were isolated by silicic acid column and thin-layer chromatography and identified by infrared spectrophotometry. The average recovery of diglycerides was 93.3%. Controls contained negligible

Summary Both positional isomers of dichloropropanol, diethoxy propanol and propanol, were esterified with butyric and palmitic acid and the resulting esters subjected to milk lipase action. Since insignificant hydrolysis occurred when the fatty acid
