The Quality and Composition of Fatty Acids in Adipose Tissue-Derived from Wild Animals; A Pilot Study

The aim of this work was to study the quality (oxidative stability), fatty acids (FAs) profile and their distribution in triacylglycerol (TAG) molecules of hunted game wild fat (HGWF) obtained from wild boar, badger, and wild goose. Health lipid indices were calculated. The determination of FAs comp...
