Carbonyl Compounds in Cow and Buffalo Milk Fat

Cow and buffalo milk fat were analyzed for carbonyls over 1 yr to study the interrelationship among classes of carbonyls. Correlation between total carbonyls and ketoglycerides was positive. Monocarbonyl content of buffalo milk fat was higher than that of cow milk fat. Cow milk fat contained higher...

Description
Summary:Cow and buffalo milk fat were analyzed for carbonyls over 1 yr to study the interrelationship among classes of carbonyls. Correlation between total carbonyls and ketoglycerides was positive. Monocarbonyl content of buffalo milk fat was higher than that of cow milk fat. Cow milk fat contained higher quantities (nearly twice) of β-ketoglycerides than buffalo milk fat. The percentage proportion of methyl ketones was much higher in cow than in buffalo milk fat. Colostral fat contained about 65 to 70% of carbonyls in normal milk fat. Monocarbonyls increased rapidly during the early period of lactation and gradually during the remaining period. However, ketoglycerides remained steady after a rapid increase during the early part of lactation.
