In vitro analysis of the effects of kefir fractions. (a) Total antioxidant capacity by the FRAP method of Fe3+ reduction analysis. The < 10 kDa fraction shows higher antioxidant activity compared to the others (*p < 0.5), but not as high as ascorbic acid used as the control. (b) Acetylcholinesterase enzyme inhibition capacity. Among the kefir fractions, the < 10 kDa fraction stands out as having the highest inhibition capacity (*indicates p < 0.5).
