microalgae in the red phase can produce significant amounts of astaxanthin, lutein, and fatty acids (FAs), which are valuable antioxidants in nutraceutics and cosmetics. Extraction of astaxanthin, lutein, and FAs from disrupted biomass of the red phase using carbon dioxide (CO₂) in supercritical fluid extraction (SFE) conditions was investigated using a bench-scale reactor in a semi-batch configuration. In particular, the effect of extraction time (20, 40, 60, 80, and 120 min), CO₂ flow rate (3.62 and 14.48 g/min) temperature (50, 65, and 80 °C), and pressure (100, 400, and 550 bar.) was explored. The results show the maximum recovery of astaxanthin and lutein achieved were 98.6% and 52.3%, respectively, at 50 °C and 550 bars, while the maximum recovery of FAs attained was 93.2% at 65 °C and 550 bars.
在红光期的微藻可以产生大量的虾青素、叶黄素和脂肪酸（FAs），这些都是营养保健品和化妆品中很有价值的抗氧化剂。本研究使用半分批配置的台式反应器，在超临界流体萃取（SFE）条件下，用二氧化碳（CO₂）从破坏的红光期生物质中萃取虾青素、叶黄素和 FAs。特别地，考察了萃取时间（20、40、60、80 和 120 分钟）、CO₂流速（3.62 和 14.48 g/min）、温度（50、65 和 80°C）和压力（100、400 和 550 bar）的影响。结果表明，在 50°C 和 550 bar 时，虾青素和叶黄素的最大回收率分别达到 98.6%和 52.3%，而 FAs 的最大回收率达到 93.2%，是在 65°C 和 550 bar 时。
