超声波法提取野生火棘果中红色素的研究
Studies on ultrasonic extraction of red pigment from wild pyracantha fortuneana fruit
摘要
Abstract
Pyracantha fortuneana is an abundant wild resource in China,its fruit has rich natural pigments and pectin. The extraction of red pigment in wild Pyracantha fortuneana were made by ultrasonic method with ethanol and compared with those of conventional solvent method. The single factor test included the solid —liquid ratio,extraction temperature ,the watt of ultrasonic,extraction time,the treatment/intermission ratio and extraction times. The optimal conditions of extraction technology were discovered by orthogonal test L9 (34). The results showed that the optimal conditions of ultrasonic extraction are as follows: the ratio of sample to solvent is 1: 9,ultrasonic watt 350W,the treatment/intermission ratio 6: 4,extraction temperature 40℃,total extraction time 50 minute,and extraction for 3 times. The extraction ratio is 96. 3% ,the yield is 22. 7% and the color value is 9. 27. Compared with the conventional solvent method,the ultrasonic method had advantages of higher extraction ratio and less extraction times. The general effect of ultrasonic method was better than that of conventional solvent method.关键词
