Research shows the importance of the presence of polyunsaturated fatty acids in our diet, mainly omega 3 and omega 6 fatty acids. This has led to the development of products known as functional foods. This type of food contains biologically active components, which offer health benefits and reduce the risk of disease. In many cases, we are looking for the manufacture of products that balance the omega 6 (ω-6) / omega 3 (ω-3) ratio that we ingest in our diet, through the incorporation of vegetable fats as a source of omega 3. Vegetable fats are currently used for functional foods, but are very susceptible to oxidation after being extracted. Because of this problem, studies are needed to develop methods to protect and preserve the polyunsaturated fatty acid content naturally present in vegetable fat. The objective of the present work is to study the effect of the addition of antioxidants in sacha inchi oil. Additionally, corroborate that the addition of antioxidants generates a product with a longer shelf life. In turn, it preserves the content of polyunsaturated fats, mainly linoleic and linolenic acids that are precursors of omega-6 and omega-3 respectively. As raw material, an extra virgin sacha inchi oil was used, which is a product rich in the mentioned polyunsaturated fats. Preliminary tests were carried out in order to select a pair of antioxidants, having as main selection criteria their solubility in the oil and that does not have adverse effects on health. The maximum concentrations of each selected antioxidant were identified, which were evaluated by the factorial design 32, resulting in 9 formulations to be tested. By measuring quality indicators, it was determined that the formulation has better results. Via this measurement was obtained the main quality indicator measured was the peroxide index, resulting in that optimum formulation was 1000 ppm of ECOPROL and 150 ppm of a mixture of tocopherols. The optimum formulation was subjected to accelerated aging to measure the effect of the addition of the antioxidant mixture to the oil, with respect to the product lifetime. The fatty acid profile and the quality of the optimum formulation was verified by physical chemical analysis (INASSA Laboratory). The results show that the incorporation of the antioxidant mixture into the sacha inchi oil maintains the quality indicators required by the NTP in the range stipulated by the same. In the present study, a peroxide value of 9.09 09 meq O2 / kg was obtained for an oil which has incorporated antioxidants, whereas an oil without antioxidants registers 11.82 meq of O2 / kg which indicates a greater oxidation. For the optimum formulation, the shelf-life method determined that the maximum shelf life were 21.82 months, approximately 4 months longer than an oil without antioxidants.
