The seed's oil content and fatty acid composition of chia (Salvia hispánica L.) var. Iztac 1, grown under six tropical ecosystems conditions

Abstract:

The highest known percentage of alfa-linolenic fatty acid, up to 67.8% compared to 36%, 53%, and 57% for camelina, peril-la and flax, respectively, is concentrated in chia oil. In recent years, chia seeds have become important for human health and nutrition because of their high content of a-linolenic fatty acid and beneficial health effects arising from consuming the w-3 fatty acids it contains. The objective of the present study was to determine the locations effect on lipid content, and fatty acid profiles, of a single chia genotype named Iztac-1. Seeds of chia genotype Iztac-1 grown on six locations (T1-T6) were tested. The a-linolenic fatty acid (w-3) comprised the great est percentage of fatty acids for oil the seeds from all of sites. The highest percentage was observed in oil of seeds from the Salinas de Ibarra location; however, there were no statistical differences (P<0.05) when compared to the contents in seeds from T4, T5, and T6. Oil of seeds from T2 showed a significant ly (P<0.05) lower a-linolenic acid percentage. Land elevation was positively related with a-linolenic fatty acid content (R2= 0.86; P<0.001). The a-linolenic fatty acid percentage was neg atively related to palmitic (R2= 0.78, P<0.001), oleic (R2= 0.73, P<0.001), and linoleic percentages (R2= 0.91. P<0.001).
