Grape pomace is one of the most abundant byproducts of the wine industry. This by-product contains many valuable bioactive substances, including polysaccharides, amino acids, and polyphenols. To enable its effective reuse, this study developed and optimized a micelle-assisted extraction process using a 2% (w/w) decyl glucoside solution aqueous as an extraction medium. The influence of key process parameters—the pomace-to-medium ratio, extraction temperature, and extraction time—was systematically evaluated to determine their impact on extraction yield and the physicochemical properties of the recovered compounds. Extraction efficiency was assessed by determining total phenolic content (TPC) and antioxidant capacity (DPPH, ABTS) using UV-VIS spectrophotometry and by determining selected phenolic compounds, amino acids, and sugars using Ultraperformance Liquid Chromatography Coupled with Tandem Mass Spectrometry (UPLC-MS/MS) The results demonstrated that all the parameters investigated significantly influenced the recovery of bioactive substances. The developed decyl glucoside-based micellar extraction proved to be an efficient, low-temperature, and environmentally favorable method for valorizing grape pomace, offering strong potential for cosmetic and related applications.
