文摘

Low temperature dilute acid hydrolysis is effective method for crop fractionation. Hydrolysis severity (CSF) of 1.90–1.97 is optimal for maximum xylose recovery. Crop digestibility increases to 0.75–0.80 after hydrolysis at CSF 1.90–1.97. Rise of CSF to 2.44 provides 0.93–0.98 digestibility while causing 40% xylose loss. Heterogeneity of cardoon stalks affects efficiency of separation processes.
