AbstractObjective: To compare the fatty acid profile of organic and conventional chia (Salvia hispanica L.) cultivars (white and black varieties) cultivated in Peru as an alternative for edible vegetable oils. Methodology: A descriptive study was carried out, which included a sample of chia seeds, from which the oil was extracted in Soxhlet oil ether machine. The acid profile was analyzed by gas chromatography. The sums of monounsaturated and saturated polyunsaturated fatty acids were determined. Likewise, the rates of atherogenicity, thrombogenicity and hypo / hypercholesterolemic were estimated. Median and interquartile range were obtained and the Friedman test was used. To evaluate the normality, the Shapiro-wilk test was used. For the quantification of the fatty acids of the chia, organic and conventional seed samples, the services of Certifications of Peru S.A. (CERPER) ®. Results: The main fatty acids present in organic and conventional chia oil, according to the order of abundance, were alpha-linolenic acid> linoleic acid> oleic acid> palmitic acid> stannic acid. As for the alpha-linolenic fatty acid (omega 3), the oil obtained from organic black and white chia seeds presented values slightly higher 63.65 (63.59-63.70) and 64.56 (63.70 -64.42) compared to conventional culture oil 63.05 (62.40-63.70) and 63.52 (63.34-63.70). The content of fatty acids, polyunsaturated and monounsaturated in chia oil, organic, showed values of 82.33% and 6.05%, being higher than those found in oil obtained from chia, from conventional culture 81, 78% and 6.17%. The content of saturated fatty acids presented a lower value of 10.70% in organic chia oil and 11.06% in chia oil obtained from conventional culture seed. The omega-3 / omega-6 ratio of chia oil, organically grown, had a higher value of 3.52, while in the conventional oil, a value of 3.42. Finally, the atherogenic and thrombogenic index showed low values, indicating high amounts of fatty acids with antiatherogenic properties in chia oil. Conclusion: The content of fatty acids in organic and conventional chia oil is within the range reported for other countries. No statistical difference was found in the comparison of both cultures.
