Food waste can be used more efficiently to increase food sustainability. Polysaccharides from jackfruit peel (PJP)1 are derived agricultural waste, and little is known about their in vitro digestion fermentation characteristics. This study aimed elucidate PJP structural properties, the dynamic changes during simulated salivary gastrointestinal fecal fermentation, its effects on human intestinal microbiota. Structural analysis showed a typical polysaccharide structure with high stability an amorphous heteropolysaccharide. The monosaccharides of glucose, mannose, galactose, arabinose, rhamnose. In models, that reach colon intact. degradation by microbiota being releasing free oligosaccharides, producing short-chain fatty acids, particularly acetic acid, modulating composition microbes. promoted growth beneficial flora Weissella, Enterococcus, Bifidobacterium, Lactococcus Prevotella process. These findings could improve usage create possibilities for use as potential prebiotic.
