Canola Oil Oleic
Canola is an oilseed crop which is grown primarily in regions of Western Canada. Each canola plant produces yellow flowers which, in turn, produce pods, similar in shape to pea pods but about 1/5th the size. Within the pods are tiny round seeds that are crushed to obtain canola oil. Each seed contains approximately 40 per cent oil. The remainder of the seed is processed into canola meal which is used as a high protein livestock feed. Nutrition experts recognize canola oil as having the best fatty acid ratio. Research indicates the fatty acid composition of canola oil is most favourable in terms of health benefits and as part of a nutritionally balanced diet. The OLEIC ACID, QsHaA, or C8HI7-CH:CH- [CH2]7 CO2 H, is an organic acid occurring as a glyceride, triolein, in nearly all fats, and in many oils, olive, almond, cod-liver, etc. It appears as a by-product in the manufacture of candles. To prepare oleic acid, the olive oil is saponified with potash, and lead acetate added; the lead salts are separated, dried, and extracted with ether, which dissolves the lead oleate; the solution is then treated with hydrochloric acid, the lead chloride filtered off, the liquid concentrated, and finally distilled under diminished pressure. Oleic acid is a colorless, odourless solid, melting at 14 and boiling at 223 (10 mm.). On exposure it turns yellow, becoming rancid. Nitric acid oxidizes it to all the fatty acids from acetic to capric. Nitrous acid gives the isomeric elaidic acid, C8H17-CH:CH-(CH2]7-C02H, which is crystalline and melts at 51. Hydriodic acid reduces both oleic and elaidic acids to stearic acid.
