| Abstract: | The Kaoliang(Chinese sorgham)glume is full of natural Kaoliang red pigment,which is of some nutritive value and highly safe for humans.It has been extracted by dilute solution of alcohol and alkalinity.But this method is costly and hard to handle.A new technology of extraction is developed it is simple,convenient,and less costly,with a higher extraction rate(8.4%)and convenient for industrial production.The Kaoliang red pigment extracted by this technical process is stable for heat and light.It has been proved that the Kaoliang red pigment is a very good natural pigment. |
