The addition of probiotic culture confers potential bio functional to food because of the ability to promote health, and the biochemical and physiological effects in the body. The objective was to produce with lactose and lactose-free yogurt with Bacillus subtilis addition and to evaluate the antioxidant potential of water-soluble peptides during the storage period. For yogurt production, a simple factorial arrangement was used to evaluate two types of milk, adding probiotic culture containing B. subtilis UFPEDA 86. The fractions were evaluated (pre-digestion and post-digestion) concerning the antioxidant elimination potential of the radical’s acid 2,2'-azino-bis (3- ethylbenzothiazoline -6-sulfonic acid) (ABTS), 2,2'-diphenyl 1-picrylhydrazyl (DPPH), chelation of copper and iron. In the evaluation of the results, the fractions obtained from the different combinations of milk, probiotic culture and different days presented antioxidant potential and chelating capacity, activities showed a significant increase after the digestion process. In addition, the results demonstrated that the B. subtilis could support the production of bio-yogurt with antioxidant potential.
