摘要

提出了用液化二甲醚(DME)提取湿型平节螺旋藻(Arthrospira platensis)脂质和功能物质的简单节能方法。在该方法中，不需要对微藻进行干燥、破坏细胞壁、加热溶剂蒸发。成功地直接提取了湿的白桦。采用液化二甲醚提取法，提取了94.2 wt%的水，得到了干燥的残渣。液化二甲醚提取的类胡萝卜素含量低于超临界二氧化碳(SC-CO2)和己烷提取的类胡萝卜素含量。此外，提取的类胡萝卜素色素的数量比用常规溶剂(如SCCO2和己烷)提取的要少。

Extraction of Lipids from Wet Arthrospira platensis by Liquefied Dimethyl Ether

Simple and energy-saving extraction of lipids and functional substances from wet Arthrospira platensis by using liquefied dimethyl ether (DME) is proposed. In the proposed method, drying of microalgae, cell wall breaking, heating for solvent evaporation is unnecessary. Direct extraction from wet A. platensis was successfully achieved. 94.2 wt% of the water in the A. platensis was removed by liquefied DME extraction and a dry residue was obtained. The amounts of carotenoid pigments extracted by liquefied DME were less than those by supercritical carbon dioxide (SC-CO2) extraction and hexane extraction. Also the amounts of carotenoid pigments extracted were smaller than those extracted with conventional solvents such as SCCO2 and hexane.

期刊介绍： Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
