Solvent exchange method in the food industry

Abstract

Solvent exchange is a promising method for developing structured materials like oleogels and aerogels. The method can potentially be used in other food processes, such as microencapsulation, modification of biopolymers, development of novel packaging materials, etc. However, the literature on such studies in food applications is limited. The present review discusses these applications where the solvent exchange process can be implemented. It explores the current challenges and potential of solvent exchange methods in the food system. The sustainability of this method is highly dependent on the solvent used and the efficiency of solvent recovery. The scalability of the process is compromised due to the complexities involved in the solvent handling and its economic cost. This review discusses critical parameters for solvent selection, including regulatory considerations and physicochemical properties, and highlights the need for further research to improve industrial applicability.
