摘要:

以鼠尾藻为原料, 采用有机溶剂法提取岩藻黄素。通过单因素实验, 分析了不同有机溶剂、料液比、温度及时间对岩藻黄素提取率的影响, 并通过响应面法对提取工艺进行优化。结果表明, 最佳的提取工艺为90%甲醇溶液, 料液比1︰33, 提取温度60℃, 提取时间3.25 h, 提取率达到1.368 mg/g。

Abstract:

In this paper, the technology of extracting fucoxanthin from Sargassum thunbergii is studied. Single-factor experiments were carried out to investigate the effects of different solvent, solid-liquid ratio, extraction temperature, and extraction time on the fucoxanthin extraction yield. The extraction technology is optimized by the response surface methodology. The results show that the optimal parameters for extraction are as follows: 90% methanol, solid-liquid ratio of 1︰32.8, 60℃ extraction temperature, and 3.25 h extraction time. The yield rate of fucoxanthin is 1.368 mg/g under optimal conditions. This work provides a theoretical basis for raw material selection for fucoxanthin extraction and the further development and utilization of S. thunbergii.
