Effects of simulated digestion and prebiotics properties of polysaccharides extracted from Imperatae Rhizoma based on different pilot processes
Provisionally accepted- Zhuhai College of Science and Techology, Zhuhai, Guangdong Province, China
This study investigated fresh Imperatae Rhizoma as the research object. After processing, dry Imperatae Rhizoma and carbonized Imperatae Rhizoma were prepared. Three polysaccharides from the fresh, dry, and carbonized Imperatae Rhizoma were extracted with traditional hot water. And another polysaccharide was obtained by cold water extraction from fresh Imperatae Rhizoma. Total four polysaccharides (IRPs) were extracted and named: IRPs-F, IRPs-D, IRPs-C, and IRPs-J. This study evaluated the prebiotic activity of four polysaccharides derived from the roots of thatch, demonstrating their resistance to digestion, their ability to promote probiotic growth, and their enhancement of short-chain fatty acid (SCFA) production. IRPs-F exhibited outstanding prebiotic activity, making it a promising candidate for functional foods aimed at improving intestinal health, immune regulation, and metabolic benefits. This research is highly relevant to food microbiology and holds significant potential for application in the functional food and gut health sectors.
