摘要
为了直接从未破壁的灵芝孢子中萃取油脂,在超临界CO2动态循环萃取之前引入静态膨胀工艺,考察了各膨胀因素对灵芝孢子油萃取率的影响。试验结果表明,膨胀压力越高,膨胀时间越短,静态萃取时间越长,越有利于灵芝孢子油的萃取,而膨胀温度过高或过低均不利于灵芝孢子油的萃取。超临界CO2静态膨胀-动态循环萃取灵芝孢子油的优化工艺为:膨胀压力30MPa,膨胀时间30s,膨胀温度70℃,静态萃取时间20min,在此条件下灵芝孢子油的萃取率达94.3%。
A static-swelling process before a dynamic-cycle process in supercritical CO2 was introduced to extract oil directedly from sporoderm-unbroken ganoderma lucidum spore. The swelling factors affecting yield of ganoderma lucidum spore oil were explored. The experimental results show that the yield of ganoderma lucidum spore oil increases with the expansion pressure and expansion time increment and the expansion time reduction. A higher or lower temperature is not beneficial to the yield. The yield of ganoderma lucidum spore oil is up to 94.3% under the optimum extraction conditions of expansion pressure 30 MPa, expansion time 30 seconds, expansion temperature 70℃ and staticextracting time 20 minutes.
