鳄梨油
英文： Avocado oil [1]
拉丁学名：Persea gratissima Caertn.,P.Americana Mill
词源
Persea 是希腊文中树的意思，而gratissima 在拉丁文中代表非常令人喜爱的。而Americana 则是指其原产地。
植物及其环境
鳄梨原产于热带及亚热带的美洲，十五世纪西班牙人发现它，并将它引进欧洲。现在盛产于西班牙和以色列等国家。
特性
鳄梨油的保存效果良好，但是不能放在冰箱中冷藏，因为部分成分会因而产生沉淀。精油在低温的状况下，出现些微混浊现象是很普通的， 甚至有些会有沉淀物产生。这两个特点可被视为好现象，这表示植物油未经大量重复精炼。鳄梨油在低温的状况下会呈凝结状态——的确鳄梨油在0℃时会呈固态，但在室温下会再度恢复液态。未精炼过的鳄梨油是深绿色的。
萃取方法
1999年由新西兰一位主厨和新西兰大学的食品研究专家研发出全新萃取技术，通过冷压技术萃取，不添加化学物质。
维生素
维生素 A 、B1 、B2和D
矿物质
钾、磷、镁、硫、钙、钠、铜
疗法用法
鳄梨油曾有段时间被视为一种春药，鳄梨果泥也曾被当成发油来刺激头发生长、加速伤口化脓及被当成药剂。
内服疗效
鳄梨几乎是一种完美的食物且易于消化。它能帮助胃部的问题、便秘或泌尿道感染，对肝脏、胆囊也有疗效。
外用疗效
◎上乘的皮肤表层软化剂。
◎相较于其他植物油，鳄梨油以高度参透表皮的参透力闻名。
◎在松弛肌肉和按摩上极有价值。
◎对修复皮肤有很好的疗效。
◎曾使用于治疗雷诺氏症引。
◎滋润、软化和抗皱，可预防提早老化。
◎对干燥的肌肤有效。
◎对皮肤炎也有效果
鳄梨油中含有一种非皂化的成分，有时候会被分离出来，这种成分对停经后的妇女维持肌肤柔顺效果绝佳。
化妆品
鳄梨油含有大量的卵磷脂，它广泛地被使用在包括口红在内的化妆品上。将鳄梨果泥当作面膜敷在脸上约20分钟，对皮肤有清洁和滋润的效果。
意事项
一般而言，无色及漂白过的鳄梨油较为常见，但奇怪的是，它们却反而比较贵，因为经过多重精炼、漂白，这种鳄梨油不适用于芳疗。鳄梨油中一些较有效的成分，通常会被分离出来作为化妆品。鳄梨油被使用于洗发精里，经过人及动物的肌肤和眼睛测试，有些微刺激性反应，但是并无证据显示会造成过敏。但也有报告指出，鳄梨的叶子、果实、树皮和种子会对牛、马、羊、兔子以及金丝雀出现毒害现象。

Avocado oil is an edible oil pressed from the fruit of the Persea americana (avocado). As a food oil, it is used as an ingredient in other dishes, and as a cooking oil. It is also used for lubrication and in cosmetics, where it is valued for its supposed regenerative and moisturizing properties.[1]
It has an unusually high smoke point, both unrefined and especially when refined. The smoke point of the unrefined form is 480 °F (249 °C) and the refined form can reach 520 °F (271 °C). The exact smoke point depends heavily on the quality of refinement and the way the oil has been handled up until reaching store shelves and subsequent kitchens.
Avocado oil functions well as a carrier oil for other flavors. It is high in monounsaturated fats and vitamin E. Because the avocado is a year-round crop, some olive oil processing facilities, particularly in Australia and New Zealand, process olive oil during the olive season, and avocado oil during the rest of the year.
Avocado oil was originally, and still is, extracted for cosmetic use because of its very high skin penetration and rapid absorption. Following pre-drying of the avocado flesh to remove as much water as possible (≈65% water in avocado flesh), avocado oil for cosmetics is traditionally extracted with solvents at elevated temperatures. After extraction, the oil for application in skin care products is usually refined, bleached, and deodorized, resulting in an odorless yellow oil. Like extra virgin olive oil, cold-pressed avocado oil is unrefined and so retains the flavor and color characteristics of the fruit flesh.[2]
Extra virgin avocado oil from the ‘Hass' cultivar has a characteristic flavor, is high in monounsaturated fatty acids, and has a high smoke point (≥250°C), making it a good oil for frying. ‘Hass' cold-pressed avocado oil is a brilliant emerald green when extracted; the color is attributed to high levels of chlorophylls and carotenoids extracted into the oil.Cold-pressed ‘Hass' avocado oil has been described as having an avocado flavor, with grassy and butter/mushroom-like flavors. Other varieties may produce oils of slightly different flavor profile as has been seen with ‘Fuerte,' which has been described as having more mushroom and less avocado flavor.[2] As a culinary oil, avocado oil compares well with olive oil. It has a similar monounsaturated fat profile which helps to protect the oil from breakdown during heating. Avocado oil is naturally low acidic, helping to increase smoke point. A virgin avocado oil, characterized by a deep emerald green color (from avocado's chlorophyll content) can safely be heated to degree of 482 F—similar to a high quality virgin olive oil. A refined avocado oil, with a higher than 500 °F (260 °C) smoke point can safely be used to conduct almost any high heat cooking application including baking, stir-fry, deep-fry, sear, barbecue, roast and saute. Avocado oil is relatively new to the culinary world and is often mislabeled in regards to smoke point. It is important to note that like all oils, the more refined, the higher the smoke point. Virgin avocado oil does not have a significantly higher smoke point than virgin olive oil.[3]
Avocado oil is one of few edible oils not derived from seeds; it is pressed from the fleshy pulp surrounding the avocado pit.[4]

鳄梨油
正面影响：鳄梨油中单不饱和脂肪的含量比其他油中的更高，这种脂肪是健康的地中海饮食的关键成分。而且它还是维生素E的上好来源。它具有轻微的坚果味道，这让它更适合作拌菜、酱汁和调味品。而且这种油的冒烟点更高，因此适合用于烧烤和煎炒。
负面影响：鳄梨油的价格非常昂贵，而且还很难买到。因为它的味道非常好，因此人们更容易过量食用。这种油不含有欧米加-3。
