Description
Yimei Hu and colleagues squeeze the seed coats of white kidney beans and ask how extraction changes the prize. These episperm polysaccharides might feed friendly gut microbes in aging bodies. Their 2026 study pulls them out three ways: ultrasound with acid, enzymes, and chelators.
Each route produced a different sugar makeup and shape, from compact porous grains to fast-dissolving fractions. In fermentation vessels with gut microbes, the acid-extracted batch fed Bifidobacterium best and yielded the most butyric acid. All batches raised helpful short-chain fatty acids and lowered harmful ones. The acid route's slow-release sugars made it the prebiotic front-runner.
