Several studies have shown that administration of diets rich in essential fatty acids helps maintain and balance various metabolic pathways of the human body and reduce the risk of disease. An alternative to enrich the daily human diet is the substitution of vegetable oils commonly used for mixed oils, which are added to oils rich in linoleic fatty acids (like safflower oil) and linolenic (such as linseed oil). The overall project will carry out the development of formulations for the study of two types of oils mixed: The MIX, based on olive oil, added safflower oil and linseed oil for use in salad dressing and the MIX B, oil-based soy, safflower oil and linseed oil for use in frying potato stick. In the overall study involved optimization of formulations, the same stability, sensory evaluation and quantification of the increased nutritional formulations that provide food for the levels of essential fatty acids, phytosterols, tocopherols, tocotrienols and phenolic compounds. One of the main difficulties related to the preparation of oil mixed with the addition of vegetable oils rich in polyunsaturated compounds involves the oxidative stability as oils rich in polyunsaturated fats have a higher susceptibility to oxidative degradation with consequent reduction in chemical stability during storage and loss of sensory characteristics, when compared to oils with a lower amount of polyunsaturated compounds. This work of undergraduate research is to evaluate the oxidative stability of different formulations of mixed oils rich in essential fatty acids, as well as the need arises from the use of antioxidants such as tocopherols and TBHQ conservative and DG.
