Abstract:Low-sugar hawthorn sweetened rolls were prepared using glucose oxidase （GOD），xylitol （Xyl），and konjac mannan oligosaccharide （KMOS）.Then，their quality was analyzed by sensory evaluation，texture，color difference，and physicochemical indexes.Additionally，the effect of the rolls on blood sugar and lipid levels in mice was studied.The results showed that compared to the rolls formulated with sucrose，the rolls with Xyl，KMOS，or their complex as sucrose substitutes exhibited significantly different apparent morphology，texture，color difference，and total sugar content （P<0.05）.Among the groups prepared with KMOS/Xyl （25∶75），the group supplemented with 0.3% GOD demonstrated increased elasticity，adhesiveness，and chewiness，as well as decreased hardness and cohesiveness.Compared with the corresponding unhydrolyzed rolls，the GOD-hydrolyzed rolls prepared with KMOS，KMOS/Xyl （25∶75，50∶50，and 75∶25） exhibited significantly decreased glucose content by 68.98%，64.71%，67.43%，and 61.57%，respectively （P<0.05），without molds or Escherichia coli.Animal experiments showed that the blood glucose and lipid levels in mice were significantly reduced，and the antioxidant capacity was enhanced in the KMOS/Xyl （25∶75） group after GOD enzymatic hydrolysis （P<0.05）.In conclusion，the quality of the rolls prepared by KMOS and/or Xyl was improved with the addition of 0.3% GOD.
