摘  要:
由于其果实中含有丰富的番茄红素,秋橄榄被认为是一种新食品资源。在本研究中,应用超临界流体CO2萃取技术对秋橄榄果肉中的番茄红素进行了萃取研究,包括对萃取压力、温度和助提剂种类等参数的优化。结果表明:增大压力和使用助提剂均可提高萃取效率。同时,超临界CO2萃取法所得产物中番茄红素含量较溶剂法产物中的高。今后如果能在提高萃取效率方面取得进展,超临界流体萃取有可能成为一种从秋橄榄果实中制备番茄红素的技术选择。

摘  要:
Autumn olive was recognized as a novel resource of food,because it contained the plenty of lycopene. In this study,an attempt was made to apply supercritical CO2 extraction technique in the extraction of lycopene from the fruit of autumn olive,including the optimum of pressure,temperature and co-extraction species. Data of this study showed that an increase in pressure and the application of co-extraction solvent resulted in an improvement of extraction efficiency. Additionally,extract by supercritical CO2 extraction contained more lycopene than that by solvent extraction. If a progress can be made in the improvement of extraction efficiency,supercritical fluid extraction will be an alternative to extract lycopene from the fruit of autumn olive.
