The release patterns and potential prebiotic characteristics of soluble and insoluble dietary fiber-bound polyphenols from pinot noir grape pomace in vitro digestion and fermentation
mycolabadmin
This study examined how grape pomace dietary fiber and its bound polyphenols are broken down in the digestive system and colon. Researchers found that soluble fiber was particularly effective at releasing beneficial compounds that feed healthy gut bacteria and produce short-chain fatty acids important for health. The fiber types promoted beneficial bacteria like Bifidobacterium while reducing harmful bacteria, suggesting grape pomace could be a valuable ingredient in functional foods to support digestive and overall health.
