Interpretive Summary: A new solvent system containing water and Natural Deep Eutectic Solvents (NPDES) was used for extraction of sugars from Agro foods such as bananas. A microwave system was used to improve the extraction process. The improved process is environmentally friendly as no toxic chemicals are used or generated. The process is expected to be economical and beneficial to the farmer as value-added products are extracted from agricultural products and wastes.

Technical Abstract: One of the common processes employed in food technology and preparation is the extraction of specific components from agro-based materials. Although many methodologies are known, continued improvements are still desirable. A recent new development is the use of natural deep eutectic solvents (NADES) for extraction. In this work, we studied NADES/water combinations and found them to be viable alternatives to conventional solvents for extraction of polar ingredients in foods. The NADES/water solvents are eco-friendly, inexpensive, chemically inert, and biodegradable. Moreover, we found microwave heating to facilitate the preparation of NADES/water solvents. Selected NADES/water systems were characterized with respect to viscosity, refractive indices, electrical conductivity, water activity, and NMR. In addition, we utilized the microwave process to facilitate the extraction of sugars in a food product with a NADES/water system. The microwave process was found to be efficient, save time, and decrease energy usage. Thus, the combination of NADES/water/microwave is a versatile method that can provide improved extractions in food systems.
