Research on complex enzyme system to extract Hibiscus Sabdariffa L reducing sugar
Abstract Hibiscus Sabdariffa L. has important nutritional and medicinal value. Currently, a safe process extraction of reducing sugar from Hibiscus Sabdariffa L. calyx by biological complex enzyme system is seldom investigated. In this experiment, the pectinase and cellulase complex enzyme system was used to optimize the enzymatic hydrolysis of Hibiscus Sabdariffa L. and Box behnken was used to design the experiment. The results showed that there was significant difference in enzymolysis effect of Hibiscus Sabdariffa L under different conditions (p < 0.05). When the enzymolysis temperature was 45 °C, pH 4.5, and the mass volume ratio of material to liquid was 5g:100ml, the optimum conditions were obtained by response surface methodology: the addition amount of pectinase and cellulase complex enzyme was 0.011 g/kg, the ratio of mixed enzyme was 1.36:1, the enzymolysis time was 2.09 h, and the reducing sugar content of Hibiscus Sabdariffa L extract was 3.56 mg/ml. The experimental results of reducing sugar content of Hibiscus Sabdariffa L (3.54 ± 0.1mg / ml) were in good agreement with the predicted value of the equation fitted by response surface. The mixed enzyme system of pectinase and cellulase has the advantages of environmental protection and energy saving, which can provide guidance for industrial production.
