1从天然食用紫卷心菜中提取紫红色素,用水作为提取剂并对提取温度、时间及次数等工艺条件进了研究,温度室温、时间为2小时、次数2次.2 微波辅助条件下,以水为溶剂直接从紫卷心菜中提取紫红色素.实验表明,微波辐射有利于色素的浸出.最佳提取条件为:微波火力为100,辐射时间180 s.3:采用单因素分析确定了超声波清洗器协助提取茗荷红色素的最佳工艺条件,时间为70分钟.4 比较三种方法提取的效果.

Answer 1

1 From natural edible pigment extracted purple cabbage,water as amaranthine extraction agents and extraction temperature,time and number and the process into the room temperature,time,for 2 hours,the number 2 times.2 Microwave-assisted conditions,water based solvent extract directly from the purple cabbage red pigment.Experiments show that microwave radiation to the leaching pigment.The best condition for:microwave irradiation time,fire for 100 180 s.3 The single factor analysis to identify the ultrasonic washing assist extraction menstrual Ming jose,the optimum technological conditions for 70 minutes.4 Compare three methods of extraction.
