以下搜集“芥花籽油”的问题及国外营养专家的回答。

Q:"I've heard that high-oleic canola oil is being used in some processed foods in place of partially hydrogenated vegetable oils. What is high-oleic canola oil?"

A:"High-oleic (or high-stability) canola oil was developed for use in commercial-scale food production because it is shelf stable and does not break down under high heat. Unlike partially hydrogenated vegetable oils found in many processed foods such as cookies and crackers, high-stability canola oil does not contain any cholesterol-raising trans fats. It contains about 70% monounsaturated fats, 20% omega-6 and 3% omega-3 polyunsaturated fats, and 7% saturated fats."


问:"我听说在一些加工食品中,高油酸芥花籽油正取代部分氢化植物油。什么是高油酸芥花籽油?"

答:"高油酸(或高稳定性)芥花籽油用于商业范畴的食品生产,因为它耐贮存,高温下不分解。与在饼干、脆饼等许多加工食品中发现的部分氢化植物油相比,高稳定性的芥花籽油中绝没有增加胆固醇的反式脂肪酸。它含有大约70%的单一不饱和脂肪,3%的欧米伽6,20%的欧米伽3多不饱和脂肪及7%的饱和脂肪。"

Q:"Is canola oil a vegetable oil?"

A:"Yes, but it is important to know that all vegetable oils are not the same. Having “vegetable oil” on the label allows the company to use a variety of different oils without having to change the label. You may see “may contain soybean oil and/or corn oil and/or sunflower oil and/or canola oil” in the ingredient list. Despite the pictures on some labels of vegetable oil, it is not made from vegetables such as lettuce, carrots or tomatoes."


问:"芥花籽油是植物油吗?"

答:"是的,但重要的是要知道植物油都是不一样的。标签上写着“植物油”以便公司在制不同种类油的时候就不用换标签了。你可能会在成分列表中看到“可能含有大豆油、玉米油、葵花油、菜籽油”的字样。别看一些植物油的标签上有图片,它可能不是由生菜、胡萝卜和西红柿这样的蔬菜压榨的。"

Q:"Is canola oil gluten free?"

A:"Canola oil is naturally gluten free. Even though it may be grown on fields that wheat has been previously grown on, when canola seed is delivered to the crushing plant, it is extensively cleaned before processing. Due to the massive difference in seed size between a wheat kernel and a canola seed, if there was any contamination, it would be removed at this stage. Furthermore, after canola is crushed and refined, repeated testing has proven that there are no detectable levels of protein in refined canola oil when it goes out to the supermarket shelves."


问:"芥花籽油不含谷蛋白吗?"

答:"芥花籽油是天然不含谷蛋白。尽管可能它生长的地方之前是种植小麦的,但在把芥花籽送到压榨厂进行加工之前,它是要经过大范围清洁作业的。由于小麦内核和芥花籽在大小上存在巨大差异,就算是有混杂物,也会在这个步骤中被剔除。此外,芥花籽被碾碎提纯后还得经过反复测试,确保在上超市货架前,精制的芥花籽油中绝无可检测水平的蛋白质。"

Q:"Which oil(s) are the safest to deep fry or stir fry?"

A:"The first rule of thumb when choosing an oil for deep frying or stir frying, is to choose one with a high smoke point, well over the standard frying temperature of 375˚F. Canola oil has a smoke point of 468˚F. To compare the smoke points of some common cooking oils:"


Canola oil has been shown to be safe and healthy in a variety of high heat cooking applications such as stir-frying, deep-frying and baking. We also have a resource which outlines deep-frying practices, as well as how to safely filter, store and reuse oil.

问:"哪种油对于油炸或炒菜来说是最安全的?"

答:"第一条经验原则就是在选择适合油炸或爆炒的油时,要选一个烟点高的,要超过标准煎炸温度375˚F才好,而芥花籽油的烟点468˚F。下面就比较一些常见食用油的烟点:"

烹饪用油 烟点(华氏温度) 烟点(摄氏温度)
