Erucic acid is an unsaturated fatty acid, which exists in many oil crops, such as mustard seeds and rapeseed. Oilseeds with high erucic acid content are prone to produce harmful substances, such as nitrous acid, when heated or fried. The rapeseed oil with low erucic acid content is reduced to a lower level by using optimized rapeseed varieties and special production technology.
The nutritional value of low erucic rapeseed oil is equivalent to that of ordinary rapeseed oil, and it is rich in unsaturated fatty acids, vitamin E and other nutrients, which is beneficial to human health. At the same time, low erucic acid rapeseed oil has a high smoke point, which is suitable for high-temperature cooking and frying food, and it is not easy to produce harmful substances and is relatively healthy. ?
It should be noted that although the erucic acid content of low erucic acid rapeseed oil is low, its fatty acid composition is similar to other vegetable oils, and it is still a high-fat and high-calorie food, so it is appropriate to eat it in moderation.
