Separation of piperine from pepper supercritical CO2 extract

According to the results of single factor investigation, it is preliminarily determined that the separation process of piperine in the supercritical CO2 extract of pepper is: dripping absolute ethanol in a constant temperature water bath at 40℃, the dosage is 1:5 (w/v), and then 1℃/ The cooling rate of 5min is reduced to 0℃, and it is placed at 0℃ for 4h to crystallize.

Celery seed oil exists in the cells of seeds, with less oil in the seed coat and more oil in the seed kernels. In order to increase the contact area between CO2 and seeds and reduce the diffusion distance between extractant and extractant in the biological matrix, it is necessary to grind it to the appropriate size according to the raw materials.
