Abstract:
OBJECTIVE:To optimize the technology conditions of water-soluble chitosan on Huang'e gel water extract solu-tion. METHODS:Using the comprehensive scores of transmittance ratio,impurity removal rate,naringin retention rate as indexes, Box-Behnken response surface method was used to optimize the amount of water-soluble chitosan,shocking time and temperature in clarifying technology,and verification test was conducted. RESULTS:The clarification effect was the best when the volume ra-tio of TCM extract solution with proportion ≥1.3 to amount of 0.01 g/mL water-soluble chitosan was 2.2,shocking for 100 min at 70 ℃. In the verification test,the average transmittance ratio was 87.3%,impurity removal rate was 41.5%,and naringin reten-tion rate was 131.38%. The measured values of comprehensive scores were 97.35%,98.92% and 98.04%,showing relative error of -0.87%,0.73% and -0.16% with the predicted values(98.27%),respectively. CONCLUSIONS:The method can effectively optimize the clarification technology parameters of water-soluble chitosan on Huang'e gel water extract solution.
