Barley extrudates modulate the gut microbiome-metabolome axis in vitro through β-glucan fermentation and polyphenol biotransformation.

Abstract excerpt

Barley is rich in fermentable dietary fiber and phenolic compounds, both of which have recognized benefits for gut health and whose functionality is influenced by processing. Here, four barley genotypes differing in β-glucan content, type of starch, and phenolic profiles were extruded to obtain ready-to-eat products, which were then evaluated using a combined in vitro digestion-colonic fermentation model. The...
