同时蒸馏萃取法提取花生油挥发性物质的研究

Study on Extraction Volatiles in Peanut Oil by SDE

摘要:

采用同时蒸馏萃取法结合气相色谱-质谱分析技术（SDE-GC-MS），对水酶法制备的花生油挥发性物质进行提取和分析，优化同时蒸馏萃取条件。结果表明：花生油总挥发性化合物种类及吡嗪类化合物相对含量均随样品量的增加而增加；二氯甲烷作为萃取溶剂萃取得到的总挥发性化合物种类及吡嗪类化合物相对含量较乙醚多；在花生油用量为30 g时，采用二氯甲烷可以萃取出66种化合物，经质谱分析可鉴定出42种化合物，其中吡嗪类化合物有6种，占总挥发性成分6.73%。

Abstract:

This paper extract and analysis volatiles in Aqueous Enzymatic Extraction of Peanut oil by SDE-GC-MS,optimized the condition of SDE. The result indicated that: the total volatile conpounds of peanut oil and pyrazine relative content raised with the increase of sample weight; Dichloromethane as an extraction solvent extracted the total volatile conpounds of peanut oil and pyrazine relative content more than ether extracion;66 volatile compounds are extracted using the sample weight 30g and extraction solvent dichloromethane, while 42 volatile compounds are identified with GC-MS. 6 pyrazines were 6.73%.
