Summary In this study, in vitro digestion and fermentation of Flammulina velutipes ‐derived polysaccharides ( FVP ) were investigated. It was found that FVP mainly consisted of 48.45% glucose, 15.40% mannose, 14.60% xylose, 11.80% fucose and 9.90% galactose. The ‐human saliva, simulated gastric and small intestinal juices conditions did not break down the FVP . Based on in vitro fermentation tests, FVP modulated the composition of gut microbiota by elevating the amounts of Bifidobacteriaceae and Bacteroidaceae and reducing the numbers of genera Lachnospiraceae and Enterococcaceae . Meanwhile, FVP affected the synthesis of short‐chain fatty acids derived from gut microbiota.
