Description

technical field

[0001] The invention belongs to the field of chemical separation technology, which is related to food industry, pharmaceutical industry and cosmetic industry. Specifically, it involves the use of supercritical CO 2 Fluid extraction technology and the method of extracting active ingredients in natural products with molecular distillation technology. That is, the present invention provides a supercritical CO 2 Fluid extraction technology and molecular distillation technology are cleverly combined to extract a new method of active ingredients in natural products. Background technique

[0002] Supercritical fluid extraction technology is a new type of chemical separation technology developed by taking advantage of the specific increase in the solubility of fluids above the critical temperature (Tc) and critical pressure (Pc). Due to CO 2 Its Tc=31.06°C; Pc=7.39MPa; and critical density ρc=0.448 g / cm 3 , that is, its working temperature is closest to room tem...
