| Abstract: | With peanut shell as raw material,through ultrasound-assisted alkali extraction of xylan,the single factor experiments selection for the agitation and level were studied.On this basis,according to the Box-Benhnken design principle and response surface analysis(RSA)method,taking account of various factors on xylanase extraction,it was concluded that the influence of alkali distillation peanut shells xylan,the best extraction process conditions for alkali concentration was 7%,temperature was 78.1℃,processing time was 80min,solid-liquid ratio was 1:16,ultrasonic power was 120W.The verification actual measurement xylan extraction rate was 56.43%,and predicted value was 57.13%. |
