Abstract

Olive-pomace oil is rich in oleic acid, and thus it can be an interesting dietary fat alternative as it can allow reaching the recommendation of consuming 20% of total diet energy in the form of monounsaturated fatty acids. In addition, olive-pomace oil also contains a wide range of minor components that may contribute to its healthy properties. The major components identified with healthy properties are triterpenic dialcohols and acids, squalene, tocopherols, sterols, fatty alcohols and phenolic compounds. The refining process, that the crude pomace-oil must undergo for commercial purposes, significantly reduces the content of phenolic compounds, while the other minor components remain at concentrations which can induce positive health effects, especially on cardiovascular health, outstanding pentacyclic triterpenes and aliphatic fatty alcohols in olive-pomace oil. Numerous in vitro and preclinical studies support that mainly the pure compounds, or extracts isolated from plant sources, play an important role in preventing cardiovascular disease and risk factors. Likewise, tocopherols, squalene and phytosterols, in addition to the minor fraction of phenolic compounds, have shown high biological activity with particular association to the cardiovascular function. In the light of the foregoing, and taking into consideration the absence of clinical studies with olive-pomace oil, it would be of great interest to develop randomized, crossover, controlled, double-blind studies to extend the knowledge and understanding on the health effects of olive-pomace olive.

 抽象的

橄榄果渣油富含油酸，因此它可以成为一种有趣的膳食脂肪替代品，因为它可以达到以单不饱和脂肪酸形式消耗总膳食能量 20% 的建议。此外，橄榄果渣油还含有多种可能有助于其健康特性的微量成分。具有健康特性的主要成分是三萜二醇和酸、角鲨烯、生育酚、甾醇、脂肪醇和酚类化合物。出于商业目的，粗果渣油必须经过精炼过程，显着降低酚类化合物的含量，而其他微量成分仍保持在可产生积极健康影响的浓度，特别是对心血管健康、突出的五环三萜和脂肪族脂肪橄榄果渣油中的醇。大量体外和临床前研究表明，主要是纯化合物或从植物中分离的提取物在预防心血管疾病和危险因素方面发挥着重要作用。同样，除了少量酚类化合物外，生育酚、角鲨烯和植物甾醇也显示出与心血管功能特别相关的高生物活性。鉴于上述情况，并考虑到缺乏橄榄果渣油的临床研究，开展随机、交叉、对照、双盲研究以扩展对健康影响的认识和理解将是非常有意义的橄榄果渣橄榄。
