The objective of the present study was to evaluate the antioxidant activity of peptides obtained by enzymatic hydrolysis from the reserve proteins of chia seeds. The contents of the protein fractions of albumins, globulins, prolamins and glutelinsin the seeds were 3.1, 3.2, 2.6 and 3.8 mg/g of chia flour respectively. Treatment with the Eap1 protease made it possible to obtain peptides from 1.4 mg/g of chia flour. The fractions with the highest amounts of released peptides were globulin, prolamin and glutelin. Allthe fractions of protein and peptides were inhibited by two radicals:1,1-diphenyl-2-picrylhidazil (DPPH) and 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS). The glutelin and prolamin peptides inhibited the DPPH and ABTS radicals at 59 and 4%. Chia seeds contain reserve proteins that were inhibited by the DPPH and ABTS radicals, as were the peptides released from them by enzymatic hydrolysis. Therefore, they may have potential applications in the food, pharmaceutical and cosmetics industries.

Keywords: Chia, peptides, inhibition, ABTS radical, DPPH radical
