Abstract

The application of a new process based on the hydrothermal treatment of olive oil waste (alperujo) led to a final solid rich in pomace olive oil (POO) enriched in minor components with functional activities. The effects of the time (15-90 min) and the temperature (150, 160, and 170 °C) of the thermal processing of alperujo on the yield, quality, and enrichment of minor components of crude POO were evaluated. The final treated solid had an increase in oil yield up to 97%, with a reduction in solids up to 35.6-47.6% by solubilization. Sterols increased up to 33%, aliphatic alcohols increased up to 92%, triterpenic alcohols increased up to 31%, squalene increased up to 43%, tocopherols increased up to 57%, and oleanolic acid increased up to 16% by the new treatment. The increase maintains a high concentration of functional substances probably even in the refining POO.

摘要

一种基于橄榄油废料（油渣）水热处理的新工艺的应用，导致最终得到一种富含油渣橄榄的固体（富含具有功能活性的次要成分）。评估了油渣在 150、160 和 170°C 下热加工 15-90 分钟的时间和温度对粗制 POO 的产量、质量和次要成分富集的影响。最终处理的固体的油产量增加了 97%，通过溶解，固体减少了 35.6-47.6%。甾醇增加了 33%，脂肪醇增加了 92%，三萜醇增加了 31%，角鲨烯增加了 43%，生育酚增加了 57%，齐墩果酸增加了 16%。这种新的处理方法保持了高浓度的功能物质，即使在精炼 POO 中也是如此。
