摘要：

Optimization of conditions for sugar beet pulp pectin (SBPP) extraction was investigated using response surface methodology (RSM). The average molecular weight ((M-t') over bar,) of twenty-nine SBPP samples was determined by viscometry. The relationships between four variables and two responses were studied using Box-Behnken experimental design. The constructed models were adequate to explain the relationships between independent variables and responses. All studied factors had great influence on the yield. The satisfactory conditions for SBPP extraction were obtained as follows: 152.63W of power, 3.53 min of time, 1.57 of pH of sulfuric and 18.92 of SLR. Among the studied factors, pH of sulfuric acid had the greatest influence on (M-t') over bar. (C) 2011 Elsevier Ltd. All rights reserved.
