For polyphenol extraction, we compared two methods: conventional extraction using water and alcohol solutions, and the supercritical CO2 technique with ethanol as a cosolvent. The conventional method yielded at least 30% more polyphenols compared to the advanced SC-CO2 technique. Experimentally chosen conditions, including a solvent composition of ethanol\u2013water (1:1; v\/v) containing 3% HCl, a liquid-to-solid ratio of 25:1 mL\/g, and 2 min of ultrasound pretreatment and conventional extraction at a temperature of 30 \u00b0C over 4.5 h, enabled an extraction efficiency of 101 mg of total polyphenols per 1 g of raw material used, with an antioxidant capacity equivalent to 600 \u00b5mol of Trolox. According to HPLC analyses, the main components of the investigated biomass were epicatechin, anthocyanins and p-coumaric acid. The extract was encapsulated in liposomes, revealing no negative effect on their stability or aggregation under the conditions tested (21 days). The study suggests that conventional water\u2013ethanol extraction can be a relatively safe and effective method for managing winemaking residuals, increasing the competitiveness of small producers through the production of high-value antioxidant additives.<\/jats:p>","DOI":"10.3390\/molecules31010072","type":"journal-article","created":{"date-parts":[[2025,12,24]],"date-time":"2025-12-24T12:22:27Z","timestamp":1766578947000},"page":"72","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Design, Sustainable Processing and Nanoliposome Encapsulation of Red Grape Pomace Rich in Polyphenolic Compounds with Antioxidant Activity"],"prefix":"10.3390","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6455-1029","authenticated-orcid":false,"given":"Katarzyna","family":"Ha\u0142dys","sequence":"first","affiliation":[{"name":"Department of Chemical Technology, Wroclaw University of Economics and Business, Komandorska 118\/120, 53-345 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1244-2554","authenticated-orcid":false,"given":"Agnieszka","family":"Ciechanowska","sequence":"additional","affiliation":[{"name":"Department of Chemical Technology, Wroclaw University of Economics and Business, Komandorska 118\/120, 53-345 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9821-8793","authenticated-orcid":false,"given":"Agnieszka","family":"Lewi\u0144ska","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, University of Wroclaw, Joliot-Curie 14, 50-383 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jomova, K., Raptova, R., Alomar, S.Y., Alwasel, S.H., Nepovimova, E., and Kuca, K.
