Cobran\u00e7osa extra virgin olive oil (EVOO), attempting to define kinetic models to predict the shelf-life (SL) during domestic use. For 9 weeks, EVOO amber glass bottles (750 mL), exposed to light (<jats:italic>n<\/jats:italic>\u2009=\u20095) or darkness (<jats:italic>n<\/jats:italic>\u2009=\u20095), at 18\u2009\u00b1\u20092 \u00baC, were opened\/shaken daily to simulate household use, with oil removed weekly. In light-exposed samples, the peroxide value (PV) imposed EVOO declassification at week five, with intense rancidity at week eight (\u2265 3.5), rendering the oil unsuitable for consumption. On the contrary, light-protected oils had only a downgrade to virgin olive oil due to a K<jats:sub>232<\/jats:sub> rise. Acidity was preserved, as was the health claim supported by tyrosol\/hydroxytyrosol polyphenols. Kinetic models (zero-, first-, and second-order) supported on the oxidation indicators (PV, K<jats:sub>232<\/jats:sub>, or K<jats:sub>268<\/jats:sub>), allowed determining reaction rates by linear regression (correlation coefficients: 0.942 to 0.997). For light-exposed oils, PV was the most reliable indicator of SL, predicting from a second-order TRUL model a preservation of the EVOO grade for 35\u2009\u00b1\u20092 days, in agreement with the experimental SL (28\u201335 days). For light-protected oils, K<jats:sub>232<\/jats:sub> was the most accurate SL indicator, predicting a SL of 49\u2009\u00b1\u20094 days using a zero-order TRUL model, consistent with the experimental SL (49\u201356 days). The models were validated using SL literature data from cvs. Arbequina, Istarska Bjelica, and Bu\u017ea olive oils, confirming their applicability to various cultivars and highlighting oxidation\u2019s role, particularly photo-oxidation, in EVOO degradation during domestic use.<\/jats:p>\n          <jats:p>\n            <jats:bold>Graphical Abstract<\/jats:bold>\n          <\/jats:p>","DOI":"10.1007\/s00217-025-04743-9","type":"journal-article","created":{"date-parts":[[2025,4,30]],"date-time":"2025-04-30T02:04:03Z","timestamp":1745978643000},"page":"1849-1864","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Influence of household conditions on the shelf-life and polyphenolic-related health claim of Cobran\u00e7osa extra virgin olive oil"],"prefix":"10.1007","volume":"251","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2774-4301","authenticated-orcid":false,"given":"Siwar","family":"Alimi","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9305-0976","authenticated-orcid":false,"given":"Nuno","family":"Rodrigues","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8196-7624","authenticated-orcid":false,"given":"Ana C.
