橄榄油是从油橄榄果实中提取的油脂。它几乎是唯一能以粗制油的形式供给食用的植物油。橄榄油的发热量大,被人体吸收率高,并几乎不含胆固醇,是国际上公认油质最好的食用油。橄榄油又是配制多种药物的重要原料,是治疗烧烫伤、 相似文献

目的:研究橄榄油生产过程的副产品橄榄叶在食品工业中的应用。方法:以橄榄叶多酚得率为评价指标,在单因素试验的基础上,利用Box-Behnken响应面法分析提取温度、提取时间、料液比对多酚得率的影响,并以过氧化值与酸价为指标,探究橄榄叶多酚对山茶籽油氧化稳定性的影响。结果:水浴法辅助提取橄榄叶中多酚物质的最优提取工艺条件为:乙醇体积分数50%,浸提时间1.0 h,料液比1∶40 (g/mL),水浴温度72℃,该条件下橄榄叶多酚得率为5.86%。橄榄叶多酚对山茶籽油具有良好的抗氧化效果,较丁基羟基茴香醚(BHA)对山茶籽油抗氧化效果好,且与特丁基对苯二酚(TBHQ)及BHA具有协同增效作用。结论:优化工艺条件下提取的橄榄叶多酚对山茶籽油具有良好的抗氧化效果。 相似文献

Frying is one of the oldest cooking procedures and is still among the most popular ones for food preparation. Due to their unique sensory characteristics, fried foods are consumed often and with pleasure. During frying, part of the oil is absorbed by the food, thereby becoming part of our diet; most interestingly, in the Mediterranean area approximately 50% of total fat intake is provided by cooking fats. Olive oil is the key lipid component of the Mediterranean diet, the health‐promoting effects of which have been largely attributed to olive oil intake. Olive oil is unique among vegetable oils due to its desirable lipid profile and some of its minor components. Scientific evidence now indicates that during frying olive oil behavior is usually equal or superior to that of refined vegetable oils. Herein, an overview of virgin olive oil performance under frying is given, with special reference to the fate of olive oil microconstituents. The compositional changes of foods fried in olive oil are also reviewed and discussed in detail. 相似文献

拉曼光谱是一种非弹性的散射光谱,基于拉曼散射效应,对与入射光频率不同的散射光谱进行分析以得到分子振动、转动方面信息,由于不同物质具有不同的特征光谱,因此拉曼光谱具有优秀的指纹能力,具有快速、灵敏检测和识别橄榄油的优势。橄榄油是所有植物油中唯一可不经提炼而直接以原始液态食用的名贵植物油,具有多种生理活性,有益人体健康。因其具有较高的商业价值从而有人铤而走险掺假伪造,如何快速有效识别橄榄油成为质量检测部门及相关企业着重关注的问题。本文从橄榄油的品质鉴定如不饱和度、碘值、游离脂肪酸、氧化稳定性和掺假鉴别两方面综述其应用研究现状,指出其存在问题并展望未来的发展趋势。 相似文献

The olive tree (Olea europaea) is widely cultivated for the production of both oil and table olives and very significant because of its economic value. Olive and olive oil, a traditional food product with thousands of years of history, are the essential components of the Mediterranean diet and are largely consumed in the world. Beside of their economical contribution to national economy, these are an important food in terms of their nutritional value. Olive and olive oil may have a role in the prevention of coronary heart disease and certain cancers because of their high levels of monosaturated fatty acids and phenolic compounds. In addition, olives (Olea europaea L.) and olive oils provide a rich source of natural antioxidants. These make them both fairly stable against auto-oxidation and suitable for human health. The aim of this paper is to define the historical development and nutritional importance of olive and olive oil constituted an important part of the Mediterranean diet. 相似文献

《2015年国际橄榄油和食用橄榄协定》(International Agreement on Olive Oil and Table Olives, 2015)是国际商品协定的一种,由联合国于2015年10月9日在日内瓦万国宫谈判后通过。基于此组建的国际橄榄理事会(International Olive Council)是全球橄榄贸易领域的权威组织。该协定最早版本于1959年首签,2015年第六版有效期至2026年12月31日。本文介绍协定内容并就以下方面进行解释:国际橄榄理事会的工作目标,橄榄油和食用橄榄的有关名词术语,成员理事会的组成方式和行政机构,各成员国在理事会的参与份额计算方式。截止2020年成员国方面的变动为伊拉克退出,增加巴勒斯坦、格鲁吉亚两个国家,文中所列成员参与份额为2020更新的数据。另外2021年毛里塔尼亚有望同意签署2015年版本协定,正式加入该组织。了解和熟悉国际橄榄油和食用橄榄协定是中国橄榄油行业融入世界贸易外循环的前提条件。作为国际大宗初级产品的主要进口和出口国,本文介绍的橄榄油和食用橄榄协定的一般原则与组织方式值得借鉴,我国应当在其它初级产品贸易规则的标准制定方面掌握主动,发出更多中国声音,为完善全球治理做出中国贡献。 相似文献

Olive oil flavour represents the most important factor that influences customer’s perception for quality. In this study, an innovative aromatisation approach that enhanced quality and shelf life of olive oil is tested by means of in situ ultrasound-assisted extraction of Carum carvi L. seeds in olive oil. After the flavouring process, carvone and limonene, representing 99 % of caraway essential oil, were identified in virgin olive oil as revealed by headspace solid-phase microextraction gas chromatograph coupled to mass spectrometer (HS-SPME gas chromatograph (GC)/mass spectrometer (MS)) analyses. Furthermore, kinetic studies indicate that flavouring rate in ultrasound-assisted system is faster than conventional aromatisation producing very stable aromatised oil with no changes in quality. This fact is attributed to ultrasound contribution to mass transfer intensification of essential oil components from seeds to the bulk medium, confirmed by scanning electron micrograph (SEM) micrographs in which cell damage and exudation of its main content are illustrated. However, it is important to note that ultrasound-treated samples produce higher degrees of conjugated dienes and conjugated trienes compared to conventional maceration. Nevertheless, this increase is not alarming and remains within permitted values of the European Community and the International Olive Oil Council (IOOC). Ultrasound-flavouring system stands as a fast alternative aromatisation method, which allows on top shelf life enhancement and olive oil quality preservation. 相似文献
