| 为进一步提高植物甾醇的脂溶性、降低熔点，提出了一种在微波辐射条件下、利用纳米金杂化CRL脂肪酶为催化剂的植物甾醇油酸酯的合成方法.以植物甾醇的转化率为指标，通过响应面法确定合成植物甾醇酯的最佳工艺条件，并对最优条件进行了验证.微波强化纳米金杂化CRL脂肪酶催化植物甾醇油酸酯的最优条件为：AuNPs粒径为15 nm、AuNPs-CRL杂化酶的添加量为8%、微波功率为320 W、反应时间为64 min，在此优化条件下测得植物甾醇的转化率为91.24%±0.42%，收率为83.73%，与预测值吻合度良好. |

| In order to further improve the lipid solubility and lower the melting point of phytosterols, an efficient method for the synthesis of phytosterol oleate under microwave irradiation using AuNPs-CRL hybridase as a catalyst was proposed. The process conditions for the synthesis of phytosterol esters were optimized by response surface analysis with the conversion rate of phytosterols as indicator, and the optimal conditions were verified. The optimization conditions for the microwave-enhanced AuNPs-CRL hybridas catalyzed the synthesis of phytosterol oleate were:the particle size of AuNPs was 15 nm, the addition of AuNPs-CRL hybridas was 8%, the microwave power was 320 W, and the reaction time was 64 min. The conversion rate of phytosterol was 91.24% ±0.42%, phytosterol ester yield was 83.73%, which was in good agreement with the predicted value. |
