Title: Study on technology of supercritical CO2 extraction of perilla oil and its integrated inclusion with α-cyclodextrin.
Abstract: Perilla oil was extracted with supercritical CO2 extraction,and the supercritical conditions for integrated inclusion of perilla oil was researched using β-cyclodextrin microcapsulation technology.The results show that the optimum conditions were: supercritical extraction pressure of perilla oil 23MPa,the optimum β-cyclodextrin inclusion supercritical pressure 12MPa,inclusion reaction time 180min,inclusion reaction temperature 55℃,extractant CO2 flow rate 40L/min.α-Lindenic acid inclusion rate is 16.37%,the maximum ratio of mass fraction of β-cyclodextrin/perilla oil is 16.42%,the highest molar complexation ratio(β-cyclodextrin/perilla oil) amounts to 1.84∶1(molar ratio of material),average mass fraction of perilla oil/β-cyclodextrin is 13.94%,and the average complexation ratio is 1.55∶1(molar ratio of material).
