菜籽油原料是什么植物

菜籽油原料是油菜。菜籽油是从油菜籽榨出来的一种食用油，由于榨油的原料是植物的种实，一般会含有一定的种子磷脂，主产于长江流域及西南、西北等地，产量居世界首位。菜籽油色泽金黄或棕黄，有一定的刺激气味，民间引叫作“青气味”。这种气味是其中含有一定量的芥子甙所致，但特优品种的油菜籽则不含这种物质。

菜籽油食用注意事项：

1、油脂有一定的保质期，放置时间太久的油不要食用。

2、因为有一些青气味，所以不适合直接用于凉拌菜。

3、高温加热后的油应避免反复使用。

4、优质菜籽油不饱和脂肪酸中的油酸含量仅次于橄榄油，平均含量在61%左右。此外，菜籽油所含有的对人体有益的油酸及亚油酸含量居各种植物油之冠。

【英文介绍/For English】：

The raw material of rapeseed oil is rapeseed. Rapeseed oil is an edible oil extracted from rapeseed. Since the raw material for oil extraction is the seeds of plants, it generally contains a certain amount of seed phospholipids. It is mainly produced in the Yangtze River Basin and southwest and northwest places, and its output ranks first in the world. . Rapeseed oil is golden or brown in color and has a certain irritating smell, which is called "green smell" by folks. This smell is caused by the presence of a certain amount of glucosinolates, but the premium varieties of rapeseed do not contain this substance.

Precautions for edible rapeseed oil:

1. Oil has a certain shelf life. Do not eat oil that has been stored for too long.

2. Because there is some green smell, it is not suitable for direct use in cold dishes.

3. The oil heated at high temperature should avoid repeated use.

4. The oleic acid content in the unsaturated fatty acids of high-quality rapeseed oil is second only to olive oil, with an average content of about 61%. In addition, rapeseed oil contains the highest content of oleic acid and linoleic acid which are beneficial to the human body among various vegetable oils.

菜籽油的主要成分是什么

菜籽油是一种植物油，是从油菜籽中提取得到的。它的主要成分是油酸、亚油酸、亚麻酸和稀释的芥子酸等。油酸占菜籽油总体积的近60%，是最主要的成分之一。油酸是一种单不饱和脂肪酸，可以帮助稳定胆固醇水平，降低心脏疾病的风险。同时，油酸具有抗炎和保护皮肤健康的功效。

亚油酸占菜籽油总体积的约20%。亚油酸是一种多不饱和脂肪酸，对人体来说是必需的脂肪酸之一。它可以降低胆固醇水平、保护心血管健康、增加细胞膜的柔韧性并具有抗炎作用。

菜籽油中的亚麻酸只有约10%，但它仍然是人体所需的必需脂肪酸之一。亚麻酸可以增强免疫系统和改善神经功能。因此，它对保持心脏健康以及预防癌症、抑郁症等疾病也有很好的功效。

除了上述三种脂肪酸外，菜籽油还含有一定量的稀释的芥子酸。芥子酸是一种单不饱和脂肪酸，有助于降低胆固醇水平、保护心血管健康和预防癌症等疾病。
