摘要：
Separation of carotenoids has been carried out on the calyx of Physalis alkekengi var. francheti by means of supercritical CO2. The influences of various parameters such as extraction pressure, temperature, processing time and particle size on the total carotenoid yield extracted are investigated in detail. A diffusion layer theory model is used to correlate the extraction yield vs. time profiles and it performs rather satisfactorily to describe the extraction process with an average absolute relative deviation varying from 3.2 to 11.0%.
