【摘要】 目的提取樱桃谷肉鸭鸭血中的血红素。方法用微波辅助酸性丙酮法制备鸭血血红素。结果单因素实验,证明了微波的功率和萃取时间对整个萃取结果影响显著。设计了正交实验,实验结果显示,确定了实验室条件下微波辅助萃取的最佳工艺条件:功率为800 W,时间为60 min,温度为50℃。结论改良传统酸性丙酮法,加入微波辅助工艺将细胞破碎和萃取过程合二为一,简化其提取工艺。更多还原

【Abstract】 OBJECTIVE To prepare heme from cherry valley duck blood. METHODS Single factor experiments and orthogonal experiment were carried out to establish the optimal process of preparing heme from cherry valley duck blood by a new microwave-assisted acid acetone extraction method. RESULTS Single factor experiments proved that the microwave-assisted extraction process significantly improved the extraction efficiency of heme. In addition,orthogonal experiment indicated the power of microwave and microwave extraction time had significant effects on the extraction results,and the optimum conditions of microwave-assisted extraction in laboratory were as follows: the power was 800 W,extraction time was 60 min,and the temperature was 50 ℃. CONCLUSION The new microwave-assisted method,combining cell disruption and heme extraction process,can simplify the traditional acid acetone extraction process,and it is proved to be feasible.更多还原
