A. Cavallaro et al., FATTY-ACID COMPOSITION AND TRANS UNSATURA TION OF THE COVERING OIL OFCANNED SARDINES, Industrie alimentari, 35(350), 1996, pp. 801
The composition in fatty acids of the covering oil of canned sardines
on the Italian and Swiss markets has been analyzed by gas-chromatograp
hy on a CP-Sil 88 capillary column. The experimental method provided a
lso the analysis of the trans isomers of the unsaturated fatty acids.
19 samples of sardines in olive oil of various provenance (Italy, Port
ugal, Spain and Marocco) have been analyzed. The level of the trans is
omers has been fairly variable: some samples have shown high values fo
r the trans isomers of linoleic and linolenic acids. Variations in the
fatty acids composition of Sardina pilchardus and the modifications b
y the interchange with lipids and the process of canning have been exa
mined.
