In recent years, a new type of solvents, natural deep eutectic solvents (NADES), have been developed and are gaining popularity as an alternative “green solvent” to conventional organic solvents. The traditional extraction of flavor or fragrance from plant materials such as vanillin is a tedious procedure that involves the use of organic solvents. In this case the solubility of vanillin and its extractability from vanilla pods in 14 NADES was evaluated. The solubility in some NADES such as lactic acid: propanediol (620 mg/mL) and lactic acid: fructose (320 mg/mL) was found to be almost similar to that of organic solvents e.g. methanol (632.94 mg/mL) or ethanol (375.81 mg/mL). Interestingly, the extractability of vanillin from vanilla pods did not reflect the results observed for the solubility tests. Some NADES with constituents that are suitable as food ingredients such as citric acid‐fructose‐glucose (CAFG), fructose‐glucose (FG), malic acid‐glucose (MAG), and malic acid‐fructose‐glucose (MAFG), showed a higher extraction power (7.6, 10.1, 16.7, and 16.3 mg/g DW, respectively) than ethanol (4.4 mg/g DW). The discrepancy between solubility and extractability might be due to differences in the interaction with the matrix depending on the NADES. The effect of water content in some NADES on the extractability of vanillin was also studied. With the high extraction capacity and the absence of toxicity of their components, NADES are very suitable for extraction of flavours and fragrances used in food and cosmetics.

天然深共熔溶剂在从香草豆荚中“绿色”提取香兰素中的应用

近年来,已经开发出一种新型的溶剂,即天然深共熔溶剂(NADES),并作为替代传统有机溶剂的“绿色溶剂”而日益普及。从植物材料(如香兰素)中提取香料或香精的传统方法很繁琐,需要使用有机溶剂。在这种情况下,对香兰素的溶解度及其在14种NADES中从香草荚中的提取能力进行了评估。发现在某些NADES中的溶解度与乳酸:丙二醇(620 mg / mL)和乳酸:果糖(320 mg / mL)几乎与有机溶剂如甲醇(632.94 mg / mL)或乙醇( 375.81 mg / mL)。有趣的是,香草豆荚中香兰素的提取能力并未反映出溶解度测试的结果。一些具有适合作为食品成分的NADES,例如柠檬酸果糖葡萄糖(CAFG),果糖葡萄糖(FG),苹果酸葡萄糖(MAG)和苹果酸果糖葡萄糖(MAFG),比乙醇(4.4 mg / g DW)具有更高的提取能力(分别为7.6、10.1、16.7和16.3 mg / g DW)。溶解度和可萃取性之间的差异可能是由于与NADES的相互作用而与基质之间的差异所致。还研究了某些NADES中水含量对香兰素可萃取性的影响。由于具有较高的提取能力,并且其成分没有毒性,因此NADES非常适合提取食品和化妆品中使用的香精和香料。苹果酸-果糖-葡萄糖(MAFG)的提取力(分别为7.6、10.1、16.7和16.3 mg / g DW)比乙醇(4.4 mg / g DW)高。溶解度和可萃取性之间的差异可能是由于与NADES的相互作用而与基质之间的差异所致。还研究了某些NADES中水含量对香兰素可萃取性的影响。由于具有较高的提取能力,并且其成分没有毒性,因此NADES非常适合提取食品和化妆品中使用的香精和香料。苹果酸-果糖-葡萄糖(MAFG)的提取力(分别为7.6、10.1、16.7和16.3 mg / g DW)比乙醇(4.4 mg / g DW)高。溶解度和可萃取性之间的差异可能是由于与NADES的相互作用而与基质之间的差异所致。还研究了某些NADES中水含量对香兰素可萃取性的影响。由于具有较高的提取能力,并且其成分没有毒性,因此NADES非常适合提取食品和化妆品中使用的香精和香料。还研究了某些NADES中水含量对香兰素可萃取性的影响。由于具有较高的提取能力,并且其成分没有毒性,因此NADES非常适合提取食品和化妆品中使用的香精和香料。还研究了某些NADES中水含量对香兰素可萃取性的影响。由于具有较高的提取能力,并且其成分没有毒性,因此NADES非常适合提取食品和化妆品中使用的香精和香料。
