AbstractTo improve the utilization of sugar beet pulp，sugarbeet pulp was used as raw material to analyze its main components such as soluble dietary fiber and insoluble dietary fiber.Dietary fiber was extracted using chemical and enzymatic （single and compound）methods，and the extraction rates of different methods were compared.The swelling powerand water-holdingcapacitywerealso measured.Theresultsshowed thatthe total dietar fiber content in sugar beet pulp was relatively high，at 43.57 g/100 . The extraction rate of dietary fiber using a combination of α （2 -amylase and cellulase was higher，reaching 65.27% . Theswelling capacity and water-holding capacity of soluble dietary fiber extracted by the enzymatic method were 4.8mL/g and 4.125g/g ，respectively，higher than those of insoluble dietary fiber.Theresults provide areference for the eficientutilization and production research of sugar beet pulp.

膳食纤维在蔬菜、水果、粗粮杂粮、豆类及菌藻类等食物中含量丰富，根据溶解性不同可分为可溶性膳食纤维（SDF）和不溶性膳食纤维（IDF），该元素虽然不能被人体消化吸收，但具有重要的生理作用。（剩余4075字）
