We analyzed two kinds of dairy fat differing in their contents of cis9, trans11-conjugated linoleic acid (cis9,trans 11-CLA or rumenic acid), and determined the positional distribution of this CLA-isomer within the three sn- positions of the triacylglycerol. In the high rumenic acid fat (HR), the CLA-isomers amounted to 2.1% of total fatty acids, and 0.8% in the low rumenic acid fat (LR). Over ...

Conjugated linoleic acid (CLA) and CLA isomers, present naturally in dairy meat products, are the natural functional components. Ruminal microorganisms, such as Butyrivibrio fibrosolvens, lactic bacteria (LAB), propionibacteria can convert (LA) to CLA. In this study, effect of different concentrations (0, 0.5, 1, 2%) storage time 2, 7, 14 21 days) on content kefir was investigated. The highest ...
