Sažetak
Agro-industrial sustainable economy indicates further exploitation of waste disposal because industry by-products are a source of esteemed bioactive compounds. Grape pomace is a major by-product coming from the winemaking industry and is generated in large quantities every year. To improve the environmental impact of the wine production process, grape pomace is used as a source for the isolation of phytochemicals such as phenolic acids, flavonoids, and tannins. Optimization of extraction techniques is an important step to achieving a maximum level of phenolic compounds from the source. Extraction processes favour the implementation of novel green technology methods as an alternative to energy-consuming and aggressive techniques that are still used. Solidliquid extraction is a classic method for extracting polyphenols made by agitation at a certain temperature using different solvents. Natural deep eutectic solvents (NADES) fulfl principles of green chemistry, making them a green alternative to conventional solvents, usually different organic chemicals. NADES are an easy-to-formulate mixture of naturally occurring primary metabolites with hydroxyl, carboxyl, or amino groups that provide hydrogen bond interactions, resulting in structured liquid solvents. NADES have adjustable viscosity, a broad range of polarity, and most importantly, the capacity to solubilize a wide variety of bioactive molecules. NADES increase extraction efciency due to the possibility of NADES being tailor-made depending on the physicochemical properties of desired extracts. The formation of additional hydrogen bonds between NADES and solutes increases the solubilization strength of NADES. While using NADES as a solvent, extraction can be further improved by using a microwave or ultrasound-assisted extraction process. NADES are not only used for extraction but also as a solvent for organic synthesis, biocatalysis, separation process, electrochemistry, etc. In this work, we used NADES as solvents of choice for the polyphenols extraction of Graševina white grape pomace. We also compared different NADES with conventional types of solvents and different extraction techniques. Using alternative green technologies for the extraction of bioactive molecules results in a higher yield in a short extraction period with minimized energy consumption.
