Applications of reverse micelles technique in food science: A comprehensive review

Publication date: Available online 3 July 2019Source: Trends in Food Science & TechnologyAuthor(s): Xiaohong Sun, Nandika BandaraAbstractBackgroundReverse micelles (RMs) are nanometer-sized aggregates of surfactants containing encapsulated water molecules as inner cores within a bulk nonpolar solvent. With special confined aqueous cores, RMs have emerged as a useful technique with a variety of applications in food science; however still lacking a comprehensive review in the subject area. This paper aims to critically review the research on the applications of RMs in food science, which allow us to better understand its current status, limits and potential.Scope and approachThe current applications of RMs in food science were reviewed, including food protein extraction, simultaneous extraction of oils and proteins, utilization and development of effective antioxidants, separation and purification of enzymes, fabrication of enzyme-immobilized magnetic nanoparticles, and enrichment of food-derived components for analysis and quantification. The challenges and future perspectives were further discussed.Key findings and conclusionsThe major applications of RMs in food science are extraction and purification of proteins and enzymes. The solutions to overcome the challenges were proposed, such as construction of effective RMs system by more biocompatible surfactants and apolar solvents, implementing continuous extraction, and complete removal of residual surfactants from the end pro...
