Incorporation of Microencapsulated Bioactive Peptides from Brewer's Spent Grain into Wheat Crackers: Effects on Technological and Bio-functional Properties.
Article in Plant foods for human nutrition (Dordrecht, Netherlands), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The valorization of agro-industrial by-products as sources of bioactive compounds represents a key challenge for sustainable food systems. Previous studies demonstrated that microcapsules containing bioactive peptides derived from brewer's spent grain (BSG) exhibited antioxidant, antihypertensive, antidiabetogenic, and hypoglycemic effects in animal models. However, their application in real food systems remains unexplored. In this study, wheat crackers enriched with microencapsulated bioactive peptides from BSG were developed to evaluate their technological characteristics and post-digestive bio-functional properties. Two formulations were prepared: control crackers (C) and crackers containing 2% microcapsules (CM). The incorporation of microcapsules reduced the spread ratio (13.2 vs. 9.8) and increased hardness (1660 vs. 2518 g), while promoting darker and redder color. FTIR analysis suggested the presence of peptide-polysaccharide interactions in the enriched crackers associated with the encapsulating matrix. After simulated gastrointestinal digestion, amino acid profiling of dialysates revealed differences in the bioaccessibility patterns between C and CM. Additionally, CM showed higher inhibitory activity against α-glucosidase (90 vs. 85%), DPP-IV (73 vs. 61%), tyrosinase (54 vs. 40%), and ACE-I (40 vs. 37%) than C, with similar antioxidant activity. These results demonstrate that microencapsulation enables the incorporation of BSG-derived peptides into a cereal-based matrix while preserving their bioactivity, highlighting their potential application in the development of functional foods targeting metabolic health.
