TI  - Investigation of fatty acid composition and trans fatty acid formation in extracted oils from French-fried potatoes and classifcation of samples using chemometric approaches
AB  - The present study investigates fatty acid composition and trans fatty acid formation in oils extracted from French-friedpotatoes, which were produced in the laboratory and collected from diferent restaurants. Potatoes were fried at 180 °C at diferentfrying periods (1, 7, 13, 19, 25, and 31 min) and the fatty acid composition of the extracted oils was determined. Principal componentanalysis and hierarchical cluster analysis were used to characterize and classify the samples. Four major fatty acids were identifedin the samples, namely palmitic acid, stearic acid, oleic acid, and linoleic acid. Linolelaidic acid (C18:2 trans) was detected in the oilsamples extracted from potatoes fried in margarine. Tree principal components (PCs) and 4 main clusters were obtained from thechemometric analysis, which characterized the samples. Tree PCs were found to be explanatory of more than 84.96% of the totalvariability in the data set.
