摘要

橄榄油是欧洲油橄榄中最受欢迎的产品,因为它的感官特性和对人体健康的有益作用。如今,人们对用药用植物富集橄榄油越来越感兴趣。在这方面,苦艾草是抗氧化剂的可食用来源。本研究的目的是通过添加苦艾草中的酚类化合物来提高突尼斯Chetoui有机橄榄油的氧化稳定性和营养价值。浸渍和超声辅助提取对橄榄油的有机标准没有影响。在一年的储存期间进行的比较研究表明,超声辅助提取导致最低的最终过氧化物和消光系数值。在贮藏末期,该方法提高了油酸含量和生物酚含量。此外,富集样品的抗自由基活性高于对照组。

Stabilization of organic extra virgin olive oil using maceration and ultrasound-assisted extraction of natural antioxidants from Artemisia absinthium leaves
Olive oil is the most popular product derived from Olea europaea L. due to its organoleptic characteristics and its beneficial effects on human health. Nowadays, there is a growing interest in olive oil enrichment with medicinal plants. In this regard, Artemisia absinthium L. is an edible source of antioxidants. The aim of the present study was to improve the oxidative stability and the nutritional value of Organic Tunisian Chetoui Olive oil by its enrichment with the phenolic compounds in Artemisia absinthium. The enrichment carried out by maceration and ultrasound-assisted extraction did not affect the organic criteria of olive oil. The comparative study, performed during one year of storage, showed that ultrasound-assisted extraction led to the lowest final peroxide and extinction coefficient values. At the end of storage, this method increased oleic acid content and biophenol contents. Furthermore, the anti-radical activities of enriched samples were higher than the control.
