UBIQUINONE IN ITALIAN HIGH-QUALITY RAW COW MILK.

The content of ubiquinone (UBN) was evaluated in Italian high-quality (HQ) raw cow milk. Samples were collected from four cowsheds in two different days during summer and winter. The fat content in HQ raw cow milk ranged between 2.86% and 3.46%, while UBN content varied between 0.15 and 0.45 µg/g milk. The fat content was significantly influenced by the cowshed only, whereas the UBN content was significantly more affected by both season and sampling days. Although UBN is a lipophilic antioxidant, no statistically significant correlation was found between UBN and fat content in HQ raw cow milk. [ABSTRACT FROM AUTHOR]
