Randomized trial evaluates bioactive potential and peptidomic profile of kefir before and after digestion, suggesting health benefits.

The aim is to evaluate the bioactive potential and peptidomic profile of goat and cow milk kefir before and after in vitro digestion.
Characterization of peptides using LC-MS/MS across undigested, gastric, and intestinal phases.
In silico analysis to identify bioactive peptide sequences.
Assessment of antioxidant and antimicrobial activities using ABTS, FRAP assays, and E. coli and S. aureus models.
Antioxidant activity was observed in undigested kefir with efficacy in ABTS and FRAP assays.
Peptide extracts showed activity across all digestion phases, maintaining efficacy especially in goat kefir against E. coli after digestion.
β-casein served as the main precursor protein, with the highest peptide identification during the gastric phase.

Lima et al. (2026) studied this question.
