摘  要：
以经超微粉碎后废弃葛渣作为原料,采用纤维素酶酶解的方法,使葛渣不溶性膳食纤维(IDF)部分转变为可溶性膳食纤维(SDF)。以SDF的得率为考察指标,通过单因素试验和正交试验对影响SDF得率的指标进行优化。结果表明,当料液比1∶16(g∶m L)、酶用量1.2 g/L、提取温度70℃、溶液p H 3.8时,SDF的得率最高,可达到15.6%。

摘  要：
Pueraia roots residues which was prepared by ultrafine grinding technology was used as raw material in the experiment. Using cellulase to prepare soluble dietary fiber by modifying insoluble dietary fiber. Taking the yield rate of SDF as the index of investigation to study the effect of temperature,time,p H,enzyme added and solid-liquid rate. The extraction process of SDF from pueraia roots residues were identified and optimized through single-factor experiments and orthogonal experiments. Results showed that the optimum conditions were solid-liquid rate of 1∶16,enzyme added of 1.2 g/L,extraction temperature of 70 ℃ and pH 3.8. Under this conditions,the SDF yield was the highest of 15.6%.
