apeseed oil is what we commonly call rape oil, also called rapeseed oil, coriander oil, canola oil and is a kind of edible oil squeezed out of rapeseed. It is one of the main edible oils in my country. It is mainly produced in the Yangtze River Basin, southwest, northwest and other places, and its output ranks first in the world.
Rapeseed oil is yellowish greenish, with an unpleasant smell and spicy taste. The rapeseed oil after alkali refining, decolorization and deodorization is clear and transparent, with light yellow color and no peculiar smell. There is a phenomenon of flavor recovery during storage, but the flavor is different from the original. Generally dark yellow or brown. Rapeseed oil contains 0.4-1.0% arachidic acid, 14-19% oleic acid, 12-24% linoleic acid, 31-55% erucic acid, and 1-10% linolenic acid.
