| Abstract: | The technology of continual extracting gardenia yellow by ethanol coupled with PEF was researched in this paper.The influence factors on dissolution ratio such as electric intensity,impulse frequency,pulse time,extracting temperature and extracting time were studied,and based on it,the extracting conditions were defined by orthogonal test.The result of experiment showed that the optimum extracting condition were electric field intensity 25kV·cm-1,impulse frequency 6Hz,pulse time 4s,temperature 40℃ and extracting time 15min.Under such conditions,the dissolution ratio of gardenia yellow could be reached to 90.4%. |
