Aqueous biphasic systems as a key tool for food processing

Aqueous biphasic systems (ABS) are widely known for their enhanced biocompatibility and selectivity in downstream processes. Hence, being a key tool for the extraction/separation of innumerous biomolecules. This is particularly important for the food industry considering the higher consumers’ awareness for the health hazards associated with chemicals used in food processing and applications, as well as the replacement of synthetic food additives such as pigments and preservatives. Therefore, this mini-review offers a critical perspective on the progress done over the last three years regarding the application of ABS i) for the extraction of food-related biomolecules, ii) as analytical tools in food processing, iii) as in situ bio-based platforms, iv) for the valorization of food waste, and v) to shed some light on how molecular simulation approaches may be a key element in this framework.
