Frying is a widely used method of preparing food, because it is a very fast and convenient process, and because it provides specific characteristics of color, flavor, odor, and texture, besides having great consumer acceptance. Therefore, the interest in the physiological effects that oils heated at high temperatures can cause to the human body arises. The aim of this work was to analyze the levels of frying used oil alteration in different kinds of foods served at the university restaurant at “Instituto de Biociências, Letras e Ciências Exatas” (IBILCE), in São José do Rio Preto-SP. In addition, it aims to make the restaurant aware of the good ways to fry and the commitment of providing good quality food to students and professionals of the Institute. With this purpose, determination of total polar compounds, conjugated dienoic acids, peroxide value, and fatty acid profile were analyzed. Two rapid tests were also used: 3M Fat Monitor and Oil Test kit. The results were compared with limits recommended for the disposal of oils and fats used in frying by the Brazilian Health Surveillance Agency (ANVISA), by other countries, and by other researches. Thus, it was concluded that the university restaurant provides the consumers with fried food of good quality, since none of the analyses showed results above recommended, although there is a need of improvement in the quality control of the oil used, in order to avoid unnecessary costs to the university restaurant.

Flaxseed has been widely studied around the world; its incorporation into products habitually consumed by human populations has been stimulated due to its unique nutritional value. The objective of this study was to evaluate the chemical composition of Brazilian flaxseed, to analyze the stability of lipids present in whole flaxseed flour (WFF) or partially defatted flaxseed flour (DFF) stored under several temperatures, and to investigate the effect of bread making on a product containing flaxseed. Whole flaxseed flour presented (g.100 g-1) 25.7 of insoluble fiber, 10.7 of soluble fiber, 38.9 of lipids, and 2.65 of lignan. Defatted flaxseed flour presented 65% less lipids, 36% more fiber and 56% more lignan than whole flaxseed flour. The fatty acid profile was maintained in the defatted flaxseed flour, and it presented a stable composition during storage under ambient temperature, refrigeration, and freezing. The fatty acid profile was similar in the bread containing defatted flaxseed flour after dough development, baking, and storage at room temperature or refrigerated. After baking, 89% of the lignan content was kept in bread. Results show that Brazilian flaxseed has an interesting chemical composition, and that defatted flaxseed, by-product of lipid extraction, presents a good stability to grind and storage under several temperatures. Thus, defatted flaxseed flour can be incorporated in bread, increasing its nutritional and functional value.
