The use of new synthesized ammonium-based ionic liquids was explored as an alternative to the current process implemented in the betanin extraction from red beet juice, resulting in high yields: 70% and 82%. Betanin is a vegetal pigment that has been applied to a large variety of products in the food industry, which is important, for it can work as a substitute for the red synthetic dyes used nowadays. Additionally, the use of the kosmotropic salt sodium acetate was explored in order to separate the complex formed by the ionic liquid and pigment of interest in a process that combined two techniques: ATPS (aqueous two-phase system) and SOES (salting-out extraction system). The results reveal that the studied techniques could work as a novel process for the extraction of betanin from red beet juice employing ionic liquids, which have not been tested for this purpose in other research.
探索了新型合成铵基离子液体在从甜菜根汁中提取甜菜红素中的应用，以替代当前的工艺，得到了较高的产率：70%和82%。甜菜红素是一种植物色素，已应用于食品工业的多种产品中，这很重要，因为它可以替代目前使用的红色合成染料。此外，还探索了使用具有亲物质性质的盐——醋酸钠，以在一个过程中分离由离子液体和感兴趣的色素形成的复合物，该过程结合了两种技术：双水相体系（ATPS）和加盐萃取体系（SOES）。结果表明，所研究的技术可以作为一种从甜菜根汁中提取甜菜红素的新型工艺，在其他研究中尚未对离子液体用于该目的进行测试。
