| Abstract: | The optimum technological parameters of microwave-assisted extraction of pomegranate red pigment(PRP) were studied.An orthogonal test table was used with the factors of ethanol concentration,ratio of solid to liquid,power of microwave radiation and extracting time.The content of PRP was determined by spectrophotometry.The optimum conditions are as follows: 40% EtOH as extracting solvent,solid to liguid ratio 1∶25,power of microwave 500 W and extracting time 90 s. |
