摘　　要：以胡萝卜渣为原料,采用酸水解法制备微晶纤维素,考察了酸浓度、酸解时间以及酸解温度对微晶纤维素得率的影响。通过单因素和正交试验结果分析确定优化工艺条件,并对制备的微晶纤维素性能进行分析。结果表明:优化的工艺条件是,酸浓度为6%、酸解时间60min、酸解温度80℃,微晶纤维素的得率为33.8%。The microcrystalline cellulose （MCC） was prepared with acid hydrolysis from carrot residue. The effects of MCC yield on acid concentration, acid reaction time and acid reaction temperature were investigated. The optimum conditions were obtained by single factor and orthogonal tests. And the properties of MCC were analyzed. The result of orthogonal experiment indicated that the optimum conditions for preparing MCC were acid concentration （6%）, acid reaction time（60min） and acid reaction temperature（80°C ）. The MCC yield was 33.8%
