Abstract:

Winery waste serves as a valuable source of bioactive compounds with notable antioxidant properties and significant antiradical activity. The concentration of ethyl alcohol in the extraction medium plays a crucial role in influencing both the extraction rate and the yield of bioactive compounds, as well as affecting key parameters such as: the antioxidant activity of water-soluble and fat-soluble substances, the total anthocyanin content, the total polyphenol index, the tannin content, DPPH antiradical activity, and the ability to inhibit hydrogen peroxide in both acidic and basic environments. Based on the experimental data and applying appropriate calculation methods, first-order statistical characteristics were determined. The analysis revealed non-linear dependencies, leading to the use of spline functions for developing mathematical models. This evaluation of the experimental data provides insights into the influence of various measured parameters during the trials.
