Our study’s objective was to exhaustively characterize the sterol composition of Empeltre olive oils from clonal selection during the ripening period in 2017, 2018, and 2019. We likewise assessed the influence of crop year, fruit ripening, and clonal selection on the oils’ regulatory compliance in terms of sterol composition. Empeltre olive oils were shown to have medium-range β-sitosterol and Δ5-avenasterol content, along with elevated amounts of campesterol and Δ7-stigmastenol. A total of 26% and 12% of the samples were non-compliant in terms of apparent β-sitosterol and Δ7-stigmastenol, respectively. Crop year was the most influential factor in the case of most sterols. Clone type was the least influential factor, except in the case of campesterol. Olive maturity was only significant for Δ7-sterols. We likewise applied a discriminant analysis, with “crop year” as the grouping variable: 94.9% of the oils were thereby classified correctly. 000120193 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000120193 590__ $$a5.2$$b2022 000120193 592__ $$a0.771$$b2022 000120193 591__ $$aFOOD SCIENCE & TECHNOLOGY$$b34 / 142 = 0.239$$c2022$$dQ1$$eT1 000120193 593__ $$aFood Science$$c2022$$dQ1 000120193 593__ $$aHealth Professions (miscellaneous)$$c2022$$dQ1 000120193 593__ $$aPlant Science$$c2022$$dQ1 000120193 593__ $$aMicrobiology$$c2022$$dQ2 000120193 593__ $$aHealth (social science)$$c2022$$dQ2 000120193 594__ $$a5.8$$b2022 000120193 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000120193 700__ $$0(orcid)0000-0002-5086-7839$$aSánchez-Gimeno, Ana Cristina$$uUniversidad de Zaragoza 000120193 7102_ $$12008$$2780$$aUniversidad de Zaragoza$$bDpto.
