Extra-virgin olive oil is basically used in food, but it can also be used as a source of high added-value components, such as oleocanthal and oleacein. Oleocanthal and oleacein are bioactive compounds with proven activities in the treatment of various diseases. By applying response surface methodology, oils of the Arbequina, Arbosana, and Koroneiki cultivars of super-intensive olive trees have been elaborated, under both irrigation and rainfed conditions. 289 oils have been obtained and 13 parameters per oil determined, which have been grouped into 221 models, that determine extraction performance, quality, and minor components of oils. The maximum extractable olive oil with the current technology is 89.0 ± 3.9%, with the rest remaining in the pomace. Oleacein is the component that most influences the antioxidant capacity of oils; its activity is 5.85 ± 0.33 µmol Trolox/mg. Irrigated Arbequina produces very aromatic oils. Rainfed Arbequina produces less aromatic (18.5 mg/kg of volatile) but with a higher content of phenolic compounds (514.4 mg/kg) oils. Koroneiki produces oils with a very high content of phenolic compounds but low in volatiles. For Koroneiki, the factors that maximize phenolic compounds are: rainfed crops, mill with 4.5 mm sieve, and malaxation at 40 °C for 30 min (1307.2 mg/kg of phenolic compounds, witch 500.0 mg/kg of oleacein, and 174.3 mg/kg of oleocanthal). A method to extract oleocanthal and oleacein from olive oils is proposed, as a way to develop new strategies to improve their functional properties.

精制富含油菜籽油和油精的初榨橄榄油:中试厂的建议

特级初榨橄榄油基本上用于食品中,但也可以用作高附加值成分的来源,例如油橄榄素和油精。油橄榄素和油精是生物活性化合物,在治疗各种疾病中具有公认的活性。通过应用响应面方法,在灌溉和雨育条件下,精心制作了超密集型橄榄树的Arbequina,Arbosana和Koroneiki品种的油。已获得289种油,并确定了每种油的13个参数,这些参数已分为221个模型,这些模型确定了油的提取性能,质量和微量成分。使用当前技术的最大可提取橄榄油为89.0±3.9%,其余残留在果渣中。油橄榄素是最能影响油脂抗氧化能力的成分。其活性为5.85±0.33μmolTrolox / mg。灌溉的Arbequina会产生非常芳香的油。雨养的Arbequina产生的芳香剂较少(18.5 mg / kg的挥发性物质),但酚类化合物的含量较高(514.4 mg / kg)。Koroneiki生产的油中酚类化合物含量很高,但挥发物含量低。对于Koroneiki,使酚类化合物最大化的因素包括:雨养农作物,用4.5毫米筛子碾磨,在40°C的温度下进行30分钟的错误处理(1307.2 mg / kg的酚类化合物,500.0 mg / kg的油精和174.3 mg /公斤油橄榄)。提出了一种从橄榄油中提取油橄榄香精和油精的方法,以作为开发改善其功能特性的新策略的途径。5毫克/千克挥发物),但酚类化合物含量更高(514.4毫克/千克)。Koroneiki生产的油中酚类化合物含量很高,但挥发物含量低。对于Koroneiki,使酚类化合物最大化的因素是:雨养农作物,用4.5毫米筛子碾磨和在40°C的温度下进行30分钟的错误处理(1307.2 mg / kg的酚类化合物,500.0 mg / kg的油精和174.3 mg /公斤油橄榄)。提出了一种从橄榄油中提取油橄榄香精和油精的方法,以作为开发改善其功能特性的新策略的途径。5毫克/千克挥发物),但酚类化合物含量更高(514.4毫克/千克)。Koroneiki生产的油中酚类化合物含量很高,但挥发物含量低。对于Koroneiki,使酚类化合物最大化的因素是:雨养农作物,用4.5毫米筛子碾磨和在40°C的温度下进行30分钟的错误处理(1307.2 mg / kg的酚类化合物,500.0 mg / kg的油精和174.3 mg /公斤油橄榄)。提出了一种从橄榄油中提取油橄榄香精和油精的方法,以作为开发改善其功能特性的新策略的途径。并在40°C下进行30分钟的错误处理(1307.2 mg / kg的酚类化合物,500.0 mg / kg的油精和174.3 mg / kg的油橄榄)。提出了一种从橄榄油中提取油橄榄香精和油精的方法,以作为开发改善其功能特性的新策略的途径。并在40°C下进行30分钟的错误处理(1307.2 mg / kg的酚类化合物,500.0 mg / kg的油精和174.3 mg / kg的油橄榄)。提出了一种从橄榄油中提取油橄榄香精和油精的方法,以作为开发改善其功能特性的新策略的途径。
