摘要
The present study had the purpose of evaluating the profile of fatty acids and the total alteration of cottonseed, sunflower and palm oils brought about during discontinued frying processes of cassava frozen chips. An increase in the percentage saturated fatty acids and it decrease in polyunsaturated fatty acids was observed, regardless of the type of oil used. With regard to the oil's global alteration, the results showed that palm oil. the most saturated one, underwent less alteration. However, none of the oils presented total polar compound values above the limits prescribed.
