【Abstract】 Objective: To investigate the optimum processing of genipin. Method: The β-glucosidase was used to transform the geniposide into genipin. The orthogonal test was adopted to optimize the processing of hydrolyzing geniposide and the transformation rate of genipin was chosen as judging index. Results: The optimum technological parameters of hydrolysis were pH value of 4.5,enzyme concentration of 9600 U /ml,hydrolysis temperature of 50 ℃ and time of 1 h. The transformation rate was 44.7% and the product purity was 97.3%. Conclusion: The hydrolysis technology is reasonable and feasible with a high transformation rate.更多还原
