超声波辅助酶结合碱法提取薯渣纤维素的工艺研究
Study on optimization of ultrasonic-assisted enzymatic extraction combined with alkaline hydrolysis of cellulose from sweet potato residue
摘要
Abstract
Sweet potato residue as raw material,used the ultrasonic-assisted enzymatic alkaline method extracted the cellulose from sweet potato residue.Through the optimization by single factor and orthogonal array design methods,the optimum hydrolysis conditions for the extraction of cellulose from sweet potato residue were determined to be:ultrasonic power 105W,enzyme concentration 0.6%,length of enzyme hydrolysis time 45min,NaOH concentration 7%,alkaline hydrolysis time 90min.Under these optimal conditions,the extraction yield of cellulose reached up to 80.09%,the water holding capacity and swelling capacity were 5.34g/g and 10.53mL/g,respectively.That was better than the enzyme combination alkaline process,and also a feasible and efficient method.关键词
