超临界CO_2流体萃取南瓜籽油的质量研究_李全宏 . Study on Pumpkin Seed Oil Extraction by Supercritical CO_2 Fluid

Abstract

using the pumpkin seed as material, The pumpkin seed oil respectively was extracted by supercritical fluid extraction (SFE) technology and the soxhlet’s extraction methods(SEM). The content of unsaturated fat acid was increa sed in CO2 SFE. As a reference of the yield of the pumpkin seed oil, the suitable extracting conditions of CO2 SFE of pumpkin seed oil were 35Mpa extracting pressure, 35℃ extracting temperature, 2ml/min carbon dioxide flow rate and 120min extracting time.
