Milling of olive paste during olive oil production is accompanied by continuous washing with water, i.e. malaxation. The resulting 'waste-water' is currently discarded. Since olives and olive oil are rich in natural antioxidants, we hypothesized that some of these might be extracted from the olive paste during malaxation. Interest in natural antioxidants is increasing because of the growing body of evidence indicating the involvement of oxygen-derived free radicals in several pathological processes, such as cancer and atherosclerosis. A waste-water extract was characterized by HPLC and tested in a model of lipid peroxidation, copper sulphate-induced oxidation of low density lipoproteins. The results demonstrate that waste-water extracts have powerful antioxidant activity and might therefore represent a cheap, as yet unused, source of natural antioxidants.
在橄榄油生产过程中，橄榄酱的研磨伴随着用水持续冲洗，即进行搅和。由此产生的“废水”目前被丢弃。由于橄榄和橄榄油富含天然抗氧化剂，我们推测其中一些抗氧化剂可能在搅和过程中从橄榄酱中被提取出来。由于越来越多的证据表明氧衍生自由基参与了多种病理过程，如癌症和动脉粥样硬化，人们对天然抗氧化剂的兴趣正在增加。通过高效液相色谱法对废水提取物进行了表征，并在脂质过氧化模型、硫酸铜诱导的低密度脂蛋白氧化模型中进行了测试。结果表明，废水提取物具有强大的抗氧化活性，因此可能是一种廉价的、尚未得到利用的天然抗氧化剂来源。
