Rapeseed oil: composition, refining and health effects
What it found
Rapeseed oil is rich in unsaturated fats, vitamin E, carotenoids, phenolic compounds and phytosterols, and it may help with high cholesterol, heart disease and blood sugar control.
The authors say it has a high smoke point and a neutral flavour, making it useful in cooking.
What they found
Nutritional make-up
Rapeseed oil contains unsaturated fatty acids, vitamin E, carotenoids, phenolic compounds and phytosterols.
Cooking properties
It has a high smoke point and a neutral flavour, so it can be used in many types of food preparation.
Cholesterol and heart
The oil may help with high cholesterol and cardiovascular diseases by changing the mix of fats in the blood.
Diabetes and blood sugar
It has shown promise for managing diabetes mellitus and controlling blood sugar.
Refining process
Removing phospholipids, free fatty acids and smelly volatile compounds from crude oil improves the taste and shelf life of rapeseed oil.
What the authors conclude
- They support the use of rapeseed oil for both consumers and industries.
- They highlight opportunities to improve its nutritional quality by adjusting processing parameters.
