Abstract:
The aim of this study was to assess the nutraceutical qualities of extra virgin olive oil (EVOO) samples obtained from three Sicilian olive cultivars: Nocellara, Biancolilla, and Cerasuola. We also evidenced the relationship among biophenols, base parameters and panel test scores, and evaluated the stability of the biophenols in EVOO. The assessment also took into consideration variations in olive harvesting periods and the influence of four different milling methods. A statistical analysis of the collected data revealed that the cultivar and harvesting period were the primary factors influencing the bio-phenol content, while the milling methods employed did not significantly affect the levels of biophenols in the oils. The panel test results were also illuminating as they were strongly related to the cultivar and polyphenol content. Following the criteria outlined in EC Regulation 432/2012, we selected three samples, each representing one of the cultivars, which exhibited the highest bio-phenol content to evaluate the biophenol stability during a time span of 16 months.
摘要:
这项研究的目的是评估从三个西西里橄榄品种获得的特级初榨橄榄油(EVOO)样品的营养品质:Nocellara,Biancolilla,还有Cerasuola.我们还证明了生物酚之间的关系,基本参数和面板测试分数,并评估了生物酚在EVOO中的稳定性。评估还考虑了橄榄收获期的变化以及四种不同碾磨方法的影响。对收集到的数据进行统计分析表明,品种和收获期是影响生物酚含量的主要因素,而采用的研磨方法并没有显着影响油中生物酚的水平。面板测试结果也具有启发性,因为它们与品种和多酚含量密切相关。根据EC法规432/2012中概述的标准,我们选择了三个样本,每个代表一个品种,在16个月的时间跨度内表现出最高的生物酚含量来评估生物酚的稳定性。
