Trans isomers contents of the fatty acids in meat products. (II) Adipose tissue and intramuscular fat from pork
Keywords:Adipose tissue, Fatty acid, Intramuscular fat, Pig, Trans isomer (content)
We give the results obtained for the determination of trans fatty acids in subcutaneous and intramuscular fats from different pork samples, using gas chromatography. Values obtained are low and similar in both kind of fats, with a mean value of 0.6% of C18:1 trans. A clear influence of animal feeding is detected due to the significant differences of this isomer content between samples from different origin. Also, correlations have been observed between C18:1 t. content and saturated, mono, polinsaturated fatty acids and fat intramuscular contents.
