Acrylamide, a potential carcinogen, is formed in black olives during the thermal treatment. It is known that the formation of acrylamide is dependent on the pH of the olive flesh. The purpose of this study was designed to assess the influence of packing conditions on the acrylamide production in black olives.</p><p><strong>Results: </strong>A reduction in acrylamide content of up to 20-30% was achieved by raising the pH of the fruit before packing above 7. Lactic acid improved color and addition of calcium chloride to the cover brine enhanced firmness. Sodium bicarbonate decreased acrylamide by up to 35%, although severe softening occurred. Packaging under CO<sub>2</sub> atmosphere increased acrylamide relative to air or nitrogen, indicating its unsuitability for packing this product. Likewise, no effect on acrylamide levels was observed among pitted and sliced olives, unlike in whole fruits, in which a higher concentration of acrylamide was detected, attributable to precursor localization in the seed, which produced significantly more acrylamide than the flesh or woody endocarp during isolated sterilization.</p><p><strong>Conclusion: </strong>The study identifies pH modulation as an effective mitigation strategy for acrylamide in black olives, but highlights trade-offs between reduction efficacy, texture quality and packaging conditions. The proposal does not solve the problem completely, but it may be viable on an industrial scale and will therefore provide the table olive industry with new tools to mitigate the presence of acrylamide in black olives. © 2026 The Author(s).

For grain traits, G and GS strongly affected yield (41.13% and 44.34%, respectively), 1000-kernel weight (18.45% and 74.06%), grain-size fractions (3.68-20.24% and 56.00-76.09%), sedimentation volume (4.39% and 71.17%), and protein content (4.39% and 71.17%), with a significant G × GS interaction (1.20-29.92%) indicating cultivar-specific seasonal responses. N had limited effects on yield and kernel size but increased protein content and sedimentation volume.</p><p><strong>Conclusion: </strong>The hypothesis was supported. Genotype and growing season were the dominant drivers of both anthocyanin profiles and grain traits, while nitrogen fertilization primarily improved protein-related technological quality rather than yield or kernel size. © 2026 Society of Chemical Industry.</p>","PeriodicalId":17725,"journal":{"name":"Journal of the Science of Food and Agriculture","volume":" ","pages":"5053-5061"},"PeriodicalIF":3.5,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147434087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
