Sažetak
Grape pomace is a by-product of the wine industry that can be used to produce a variety of high-value products and its utilization can prevent environmental pollution that would occur by disposing of such waste. Two approaches for the use of grape pomace were considered: (i) silage and (ii) isolation of biologically active compounds using natural deep eutectic solvents (NADES). Silage is a method of preserving wet crops under anaerobic conditions where lactic acid bacteria convert water-soluble carbohydrates into lactic acid. The process of ensiling the grape pomace itself and with an inoculum of lactic acid bacteria and zeolite was carried out. Different silage parameters were monitored through time: pH, the content of water-soluble carbohydrates, lactic acid, polyphenols, and tannins. Conventional extraction techniques for plant phenolic are usually associated with high organic solvent consumption and long extraction times. In order to establish an environmentally friendly extraction method for grape pomace polyphenols, one of the food industry by-products that is extremely rich in these biologically active compounds, natural deep eutectic solvents (NADES) are used as a green alternative to conventional solvents. Extraction was performed using NADES betaine: sucrose (4:1). According to the obtained results in two tested approaches for grape pomace disposal, silage has proven to be effective and industrially suitable. The green technology of using NADES with a high polyphenol isolation capacity has proven to be effective in isolating various compounds and the production of a high-value product for human use.
