超声波辅助提取藏香猪血液中血红素工艺研究
Study on the technology of ultrasonic-assisted extraction of heme from the blood of Tibetan pigs
以藏香猪血液为原料,采用超声波辅助提取血红素,以血红素提取率为考察指标,研究超声温度、超声时间、超声功率、超声间歇比以及红细胞与水体积比的影响,通过单因素实验结果进行四因素三水平正交试验优化,确定最佳工艺条件。研究表明超声温度30℃,红细胞与水体积比1:5,超声时间6 min,超声功率400 W/100mL,超声间歇比4:3,在此条件下血红素的得率为(0.621±0.021)g/100mL,远优于常规方法得率(0.320±0.017)g/100mL。采用超声波辅助提取法能有效增加藏香猪血液中血红素的提取率。
Using Tibetan pig blood as the raw material, heme was extracted with the assistance of ultrasound. The extraction rate of heme was used as the evaluation index to investigate the effects of ultrasonic temperature, ultrasonic time, ultrasonic power, ultrasonic pulse ratio, and the volume ratio of red blood cells to water. Based on the results of single-factor experiments, a four-factor, three-level orthogonal experiment was conducted to optimize the extraction process. The optimal conditions were determined as follows: ultrasonic temperature of 30°C, red blood cell to water volume ratio of 1:5, ultrasonic time of 6 min, ultrasonic power of 400 W/100 mL, and ultrasonic pulse ratio of 4:3. Under these conditions, the heme yield reached (0.621 ± 0.021) g/100 mL, significantly higher than that obtained by conventional methods (0.320 ± 0.017) g/100 mL. The ultrasound-assisted extraction method effectively increased the extraction rate of heme from Tibetan pig blood.
