Abstract

In this study, the impact of ozonation on hazelnut oil quality was investigated. Hazelnuts were exposed to gaseous ozone at different concentrations (3.3 and 10 mg·L−1) and exposure times (30, 60, and 120 min). The fatty acid value and composition remained unchanged. β-sitosterol, campesterol, and ∆5-avenasterol contents were unaffected. With increasing ozone levels and exposure times, there was a slight rise in peroxide value and γ-tocopherol, and a decrease in α-tocopherol. The total phenolic content and antioxidant activity were lower in oil extracted from hazelnuts which had been ozonated for more than 60 min at both doses, compared to the control. Overall, the quality and composition of hazelnut oil remained stable with ozone treatments, depending on the treatment conditions.

用气态臭氧处理榛子提取的油的质量特性

本研究调查了臭氧对榛子油质量的影响。将榛子暴露于不同浓度（3.3 和 10 mg-L-1）和暴露时间（30、60 和 120 分钟）的气态臭氧中。脂肪酸值和组成保持不变。β-谷甾醇、坎贝酯醇和∆5-芒甾醇的含量未受影响。随着臭氧浓度和暴露时间的增加，过氧化值和γ-生育酚略有上升，而α-生育酚则有所下降。与对照组相比，在两种剂量下臭氧处理超过 60 分钟的榛子萃取油中的总酚含量和抗氧化活性都较低。总的来说，臭氧处理后榛子油的质量和成分保持稳定，具体取决于处理条件。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
