Abstract
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 composition was carried out by gas chromatographic analysis of fatty acid methyl esters (FAME). Enzymatic hydrolysis and thin layer chromatography were used to determine the positional distribution of FAs in the internal and external positions of triacylglycerols (the regiospecific structure of triacylglycerols) of the obtained HGWF. A pressure differential scanning calorimeter (PDSC) was used to determine the oxidative stability of tested HGWF. The lipid fraction isolated from subcutaneous adipose tissues was dominated by MUFA, on average 46–50% of total FAs, and by SFA, on average 32–36% of total FAs. Palmitic acid was located mainly in the internal position of TAGs of the analyzed HGWF, whereas external positions were occupied by unsaturated oleic acid. Such a structure is responsible for normal fat absorption from food and it prevents the formation of insoluble calcium salts. Considering FAs profile, quality and the oxidation stability among all tested fat samples, the boar fat seems to be the most favorable.
Highlights
The high nutritional value of game meat and its positive impact on human health and body functioning have been documented [1,2,3,4], a limited number of studies considering the unique features of wild animal fat are available in the literature
It is well known that the fatty acids (FAs) composition of muscle and adipose tissue mainly originates in the diet [1,5] which is not controlled in wild animals and depends on seasonal, interannual and regional discrepancies [4,6]
The findings of this study indicated that fats from boar, badger, and wild goose can be a valuable food product, further research, including microbiological tests are needed to deeply define their potential application in nutrition
Summary
The high nutritional value of game meat and its positive impact on human health and body functioning have been documented [1,2,3,4], a limited number of studies considering the unique features of wild animal fat are available in the literature. The most important parameters for evaluating the nutritional value and healthiness of fats are the ratio of polyunsaturated fatty acids (PUFA) to saturated fatty acids (SFA) and PUFA n-6/n-3 ratio, as well as hypocholesterolemic and hypercholesterolemic FAs contents [10,11,12]. PUFAs of n-3 and n-6 series are beneficial for human health. The ratio of PUFA n-6/n-3 is beneficial in meats from animals that have consumed grass, which contain high levels of α-linolenic acid (α C 18:3 n-3). Α C 18:3 n-3 is converted to a series of longer chain PUFA of which the most important are C 20:5 n-3 (EPA) and C
