Abstract

The objective of this study was to evaluate the stability of the incorporation of linolenic acid in french fries processed with a vegetable oil mixture rich in linolenic acid and with a low ratio between linolenic and linoleic acids (n-6 and n-3). The oil mixture contained 75 % of soybean oil, 20 % of linseed and 5 % of safflower and was compared to soybean oil (control). Potato french fries were subjected to successive frying for 24 h. The french fries were analysed regarding fatty acids composition, tocopherols, sterols and sensory acceptance. During successive frying with the mixture, the french fries were characterized by a higher content of linolenic acid, lower n-6/n-3 ratio, degradation of sterols and by a similar content of tocopherols. The sensory acceptance of the french fries was similar up to 18 h, when the potatoes had a content 2.1-fold higher in linolenic acid, with a 2.7-fold n-6/n-3 ratio, favouring a health-promoting diet.
