Supplementation with the NADES-based lavender extract significantly increased the total polyphenol content and antioxidant capacity, while improving the retention of total polyphenols during storage by approximately 10.3% in date-based bars and 2.8% in fig-based bars. The NADES-based lavender extract also reduced the percentage of yeast- and mold-positive samples from 60% to 20% in date-based bars after 30 days of storage at 22 \u00b0C. After 28 days of storage, supplemented bars showed better preservation of key sensory attributes, including appearance, color, odor, sweetness, bitterness and aftertaste. The stabilizing effects were more pronounced in date-based than in fig-based formulations, highlighting the influence of the food matrix on functional ingredient performance. Overall, the results indicate that NADES-based lavender extract is a promising functional ingredient for improving the physicochemical, sensory, and microbiological stability of upcycled fruit bars, particularly in date-based formulations.<\/jats:p>","DOI":"10.3390\/molecules31152608","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T08:15:56Z","timestamp":1785140156000},"page":"2608","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhancing Antioxidant and Storage Stability of Upcycled Fruit Bars Through NADES-Based Lavender Extract Addition"],"prefix":"10.3390","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2167-6862","authenticated-orcid":false,"given":"Maja","family":"Benkovi\u0107","sequence":"first","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2037-9436","authenticated-orcid":false,"given":"Manuela","family":"Pani\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"},{"name":"NADES Design Ltd., Borongajska c. 83 H, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9023-8482","authenticated-orcid":false,"given":"Marina","family":"Cvjetko Bubalo","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2438-4357","authenticated-orcid":false,"given":"Anja","family":"Damjanovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3032-903X","authenticated-orcid":false,"given":"Ana","family":"Jurinjak Tu\u0161ek","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3353-1065","authenticated-orcid":false,"given":"Davor","family":"Valinger","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6657-7337","authenticated-orcid":false,"given":"Jasenka","family":"Gajdo\u0161 Kljusuri\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1695-6766","authenticated-orcid":false,"given":"Tamara","family":"Jurina","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5156-1893","authenticated-orcid":false,"given":"Kristina","family":"Rado\u0161evi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8853-0054","authenticated-orcid":false,"given":"Ivana","family":"Radoj\u010di\u0107 Redovnikovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Food Technology and Biotechnology, University of Zagreb, Pierrotijeva 6, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Testa, R., Schifani, G., and Migliore, G.
