Abstract
Nitrated fatty acids (NO2-FAs), specifically nitroalkenes, are gaining recognition for their anti-inflammatory and therapeutic properties. Bovine milk, a major dietary component, may serve as a significant source of these bioactive molecules, complementing its established nutritional profile. This study examined nitroalkene's presence in milk from different bovine strains and lactation stages. NO2-conjugated linoleic acid (NO2-cLA) was detected at concentrations up to 5 μM, comprising 2.7% of total cLA. The concentration of NO2-cLA varied slightly with the Holstein strain and lactation stage, with its free form predominantly observed, suggesting limited triglyceride incorporation. Further research into NO2-cLA's biological significance in milk is required.
期刊介绍：
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
