Abstract

Oxidation of bread lipids during baking and storage reduces the nutritional value of the product and leads to the formation of off-flavors and off-odors. In this research, oxidative stability of rice bran, corn, canola, sunflower and soybean oils during Brotchen bread baking process and storage was evaluated. Baking process caused a significant increase in oxidative indices such as peroxide, anisidine, Totox and thiobarbitoric acid values and free fatty acid content. However, storage of breads for 6 days in room temperature did not affect the value of the indices. Generaly, the value of the indices in bread containing rice bran oil was lower than those of the other breads, which indicated the higher oxidative stability of rice bran oil in baking process and storage. Pure oils treated in simulated baking process and storage had an oxidative quality similar to that of breads. This means that bread ingridients may not have an effect on oil oxidative stability. Bread containing rice bran oil gained also higher scores in sensory evaluation, which of course were in agree with its better oxidative status.
