Insolvent extraction, a solvent is mixed with the plant material to facilitate the extraction of the oil and then is removed to leave the vegetable oil behind. Soybeans are protein-rich, and the medium viscosity oil rendered from them was high in polyunsaturates. Because the word "rape" was not considered optimal for marketing, they coined the name "canola" (from "Canada Oil low acid"). The first thing you should do is mix the raw materials and water in a vessel. Canola is very thin (unlike corn oil) and flavorless (unlike olive oil), so it largely succeeds by displacing soy oil, just as soy oil largely succeeded by displacing cottonseed oil. [64] Roger Drackett had a successful new product with Windex, but he invested heavily in soybean research, seeing it as a smart investment. How that extraction is actually achieved, on the other hand, is less simple.
