藻类含有类脂和功能化合物，如类胡萝卜素。尤其是微藻作为生物燃料的来源，近年来备受关注。为了提取这些成分，可以使用有机溶剂或超临界二氧化碳。我们一直在开发以液化(亚临界)二甲醚(DME)为溶剂、压力约为0.59兆帕的湿法萃取工艺。萃取过程通常需要耗能的干燥和研磨过程，就像超临界二氧化碳的情况一样。我们将液化二甲醚应用于从各种藻类中提取脂类和功能化合物。由于液化二甲醚萃取法可以省去干燥、细胞破裂和溶剂挥发等过程，因此可以实现更简单、低能耗的系统。本文综述了超临界CO2和亚临界DME萃取藻类的研究进展。(C)2014爱思唯尔B.V.保留所有权利。
Algae contain lipids and functional compounds such as carotenoids. Especially, microalgae are recently focused as a source of biofuel. To extract these components, organic solvent or supercritical carbon dioxide have been used. We have been developing wet extraction process using liquefied (subcritical) dimethyl ether (DME) as solvent at around 0.59 MPa. The extraction process usually requires energy consuming drying and grinding process as in the case of supercritical CO2. We have applied liquefied DME for the extraction of lipids and functional compounds from various kinds of algae. Since the liquefied DME extraction process can eliminate the process for drying, cell disruption, and solvent evaporation, it can realize simpler and low energy consumption system. In this paper, our studies on the extraction from algae by using supercritical CO2 or subcritical DME are reviewed. (C) 2014 Elsevier B.V. All rights reserved.
