The effect of alkali extraction (AE), enzymatic extraction (EE), ultrasonic-assisted enzymatic extraction (UAEE), and shear homogeneous-assisted enzymatic extraction (SHAEE) on the physicochemical, structural properties, and in vitro hypoglycemic activity of bamboo shoot dietary fibers (BSDF) were investigated and compared. BSDF obtained by AE had the lowest protein content and crystallinity index. The lowest oil holding capacity (OHC) and highest protein content were observed in EE. BSDF generated highest OHC and glucose adsorption capacity by UAEE. SHAEE obtained the highest SDF content (17.89%), water-holding capacity (8.81 g/g), and α-amylase activity inhibition ratio (19.89%) and the smallest particle size (351.33 μm). BSDF extracted by SHAEE and UAEE presented a porous and loose structure. Furthermore, the in vitro hypoglycemic activity of the four BSDF samples generally followed the order of SHAEE > UAEE > EE > AE. Results show that SHAEE is an innovative and promising method to obtain BSDF with its excellent physicochemical and functional properties.
