摘  要：
[目的]介绍三孢布拉霉中番茄红素的萃取新工艺。[方法]采用超临界二氧化碳流体萃取技术萃取三孢布拉霉中的番茄红素,研究萃取时间、萃取温度、萃取压力及二氧化碳流量对萃取率的影响。[结果]过滤后的发酵液用95%乙醇预处理后萃取3 h时番茄红素的萃取率最高;萃取温度为45℃时番茄红素的萃取率最高,之后随温度升高番茄红素的萃取率下降;最佳萃取压力为45 MPa;最佳二氧化碳流量为20 L/h。[结论]超临界二氧化碳萃取三孢布拉霉中番茄红素的最佳工艺为:压力45 MPa,温度45℃,二氧化碳流量20L/h,此条件下番茄红素的得率可达76%。

摘  要：
[Objective] The purpose of the study was to introduce the new extraction technology of lycopene from Blakeslea trispora.[Method] The lycopene was extracted from B.trispora by supercritical carbon dioxide extraction technology and the influence of extraction time,extraction temperature,extraction pressure and flow rate of carbon dioxide on the extraction rate was studied.[Result] After the filtered fermentation broth was pretreated with 95% alcohol,the extraction rate of lycopene was highest when the extraction time was 3 h;its extraction rate was highest when the extraction temperature was 45 ℃ and then its extraction rate was decreasing along with the ascending of temperature;the optimum extraction pressure was 45 MPa and the optimum flow rate of carbon dioxide was 20 L/h.[Conclusion] The optimum technology for extracting lycopene from B.trispora by supercritical carbon dioxide extraction technology was as follows: the pressure was 45 MPa,the temperature was 45 ℃ and the flow rate of carbon dioxide was 20 L/h.Under this condition,the yield rate of lycopene could reach 76%.
