The aim of this study was to determine the concentration of oleocanthal in olive pomace waste and compare this to its concentration in extra-virgin olive oil (EVOO). The concentration of oleocanthal in freshly pressed EVOO and its subsequent waste was analysed at early, mid and late season harvests. Oleocanthal concentrations were quantified using high-performance liquid chromatography-mass spectrometry. In oil, oleocanthal concentration was as follows: 123.24 ± 6.48 mg kg(-1) in early harvest, 114.20 ± 17.42 mg kg(-1) in mid harvest and 152.22 ± 10.54 mg kg(-1) in late harvest. Its concentration in waste was determined to be: 128.25 ± 11.33 mg kg(-1) in early harvest, 112.15 ± 1.51 mg kg(-1) in mid harvest and 62.35 ± 8.00 mg kg(-1) in late harvest. Overall, olive pomace waste is a valuable source of oleocanthal.
本研究旨在测定橄榄渣废弃物中油酸醇的浓度，并将其与特级初榨橄榄油（EVOO）中的浓度进行比较。在早期、中期和晚期收获时，分析了新鲜压榨的 EVOO 及其随后的废弃物中油酸醇的浓度。采用高效液相色谱-质谱法对油酸醇浓度进行定量。在油中，油酸醇的浓度如下：早期收获时为 123.24 ± 6.48 mg/kg，中期收获时为 114.20 ± 17.42 mg/kg，晚期收获时为 152.22 ± 10.54 mg/kg。废弃物中的浓度分别为：早期收获时为 128.25 ± 11.33 mg/kg，中期收获时为 112.15 ± 1.51 mg/kg，晚期收获时为 62.35 ± 8.00 mg/kg。总的来说，橄榄渣废弃物是油酸醇的一个有价值的来源。
