摘　　要：Pure wheat malt beer (PWMB) with potentially functional properties may attract consumer interest.To explore the functional properties of non-starch polysaccharides (NSPs) in PWMB,NSPs were extracted from PWMB and separated into PWMB non-starch polysaccharides-1 (PNSP-1) and PWMB non-starch polysaccharides-2 (PNSP-2) by Q-Sepharose Fast Flow column.PNSP-1 exhibited more effects on increasing the viscosity of beers,which had higher purity of 92.58% containing 88.53% arabinoxylan with arabinose/xylose (A/X) 0.60 and 2.78% β-glucan but no glucomannan and mannan;while PNSP-2 showed greater effects on promoting beer haze and foam retention,which had more diverse NSPs including 46.03% arabinoxylan with A/X 1.13,41.47% arabinogalactan,10.26% glucomannan,and 2.70% mannan but no β-glucan.Diversity of sugar composition resulted in a better antioxidant capacity of PNSP-2.NSPs proliferated Lactobacillus casei LC6117 and LC0331,but did not promote L.plantarum LP-28 and L.fermentium LF-2H.PNSP-2 was also utilized by L.rhamnosus SRG.PNSP-2 had better effects on prebiotics activities.PNSP,PNSP-1 and PNSP-2 all exhibited mild inhibitory effects on α-glucosidase and lipase but not on α-amylase,and showed a binding capacity to fat and cholesterol.This work is of great reference significance for improving the viscosity,haze,foam retention and health value of wheat beer.
