The optimum ratio of physiologically important acids puts the benefits of canola oil in the first place compared to other vegetable oils.
Perhaps the use of rapeseed oil not only as a food but also as a feedstock for a number of technical products. From it are esters of fatty acids, which may reduce the cetane number and useful as biodiesel.
The rubber industry, steel production, lubricants, production of the film - this is not a complete list of the application of rapeseed oil in the non-food purposes.
Waste generated from production of rapeseed oil (cake) is a good animal feed. But the green parts of plants rape because of the high content of vegetable protein are highly valued in agriculture, they give the animals fresh or silage.
The use of rapeseed oil
Rapeseed oil has a pleasant taste. The use of rapeseed oil is the presence of essential amino acids in its structure, which can not be synthesized in humans - linoleic and linolenic.

Also erucic acid leads to disturbances in the cardiovascular system causing cirrhosis and infiltration of the skeletal muscles. Safe threshold of the acid content in the oil is 0, 3 - 0, 6%.
Furthermore, rapeseed oil cause harm organic sulfur-containing compounds that have toxic properties - glikozinolaty, thioglycosides and derivatives thereof. They adversely affect the thyroid gland and other organs, and give the oil a bitter taste.
Breeders derived canola varieties in which the content of erucic acid and thioglycosides minimum or completely reduced to zero. Bezerukovye grade (Spar, Agate, Promin) significantly reduced damage to the rapeseed oil.
Canola variety of rapeseed contains thioglycosides. The oil extracted from it is called canola, it is completely safe for humans, and it is used for cooking, salad dressings, etc.
Do not use canola oil if its individual intolerance, diarrhea, gallstones, chronic hepatitis, as it negatively affects the liver and entire digestive tract.
