This review provides a critical overview of the antioxidant compounds present in apple pomace and explores how they may mitigate age-related oxidative damage and inflammatory responses. We focus on the nutritional profile of apple pomace including its macro- and micronutrients, with particular focus on polyphenols, such as procyanidin tannins, quercetin glycosides (rutin, quercetin-3-glucoside), phloridzin, dietary fiber, vitamins, and lipids alongside current techniques for isolating its bioactive components. Special attention is given to biological pathways through which these compounds influence aging: redox regulation via Nrf2, inflammatory modulation via NF-\u03baB, and metabolic regulation via AMPK, SIRT1 and PI3K\/Akt\/mTOR. Evidence from in vitro cellular models (HepG2, CCD-986Sk fibroblasts), in vivo rodent studies and limited human pilot trials is summarized, as well as existing and emerging applications of apple pomace in functional foods, cosmeceuticals, and other sectors. Finally, we discuss the challenges and future opportunities in harnessing this by-product of the food industry. Although clinical data remain limited, preclinical findings support the repurposing of apple pomace as a sustainable functional ingredient contributing to healthier aging and circular economy goals. Future long-term randomized controlled trials are necessary to confirm efficacy in humans.<\/jats:p>","DOI":"10.3390\/foods15071174","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T13:23:17Z","timestamp":1774963397000},"page":"1174","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Apple Pomace as a Promising By-Product with High Antioxidant Potential in the Prevention of Aging Processes"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9479-3985","authenticated-orcid":false,"given":"Kamil","family":"Wysocki","sequence":"first","affiliation":[{"name":"Department of Biotechnology and Nutrigenomics, Institute of Genetics and Animal Biotechnology, Polish Academy of Sciences, 05-552 Magdalenka, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-5388-6285","authenticated-orcid":false,"given":"Maima","family":"Matin","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Nutrigenomics, Institute of Genetics and Animal Biotechnology, Polish Academy of Sciences, 05-552 Magdalenka, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0442-6127","authenticated-orcid":false,"given":"Magdalena","family":"Koszarska","sequence":"additional","affiliation":[{"name":"Independent Researcher, 39-209 Zas\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cyprian","family":"Tomasik","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Nutrigenomics, Institute of Genetics and Animal Biotechnology, Polish Academy of Sciences, 05-552 Magdalenka, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bogumi\u0142a","family":"Zima-Kulisiewicz","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Nutrigenomics, Institute of Genetics and Animal Biotechnology, Polish Academy of Sciences, 05-552 Magdalenka, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Strza\u0142kowska","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Nutrigenomics, Institute of Genetics and Animal Biotechnology, Polish Academy of Sciences, 05-552 Magdalenka, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Leyane, T.S., Jere, S.W., and Houreld, N.N.
