Refined Bleached Deodorized (rbd) Canola Oil

Canola Oil is a Vegetable Oil derived from a variety of Rapeseed that is low in Erucic Acid (CH₃(CH₂)₇CH=CH(CH₂)₁₁COOH), as opposed to Colza Oil. Canola was originally a trademark name of the Rapeseed Association of Canada, and the name was a condensation of “Can” from Canada and “OLA ” meaning “Oil, low acid”, but is now a generic term for edible varieties of rapeseed oil in North America and Australia.

The change in name serves to distinguish it from natural rapeseed oil, which has much higher erucic acid content. There are both edible and industrial forms produced from the seed of any of several cultivars of the plant family Brassicaceae, namely cultivars of Brassica napus L., Brassica subsp. Oleifera (syn. B. campestris L.), or Brassica juncea, which are also referred to as “Canola”.

According to the Canola Council of Canada, an industry association, the official definition of canola is “Seeds of the genus Brassica (Brassica napus, Brassica rapa or Brassica juncea) from which the oil shall contain less than 2% erucic acid in its fatty acid profile and the solid component shall contain less than 30 micromoles of any one or any mixture of 3–butenyl glucosinolate, 4–pentenyl glucosinolate, 2–hydroxy–3 butenyl glucosinolate, and 2–hydroxy–4–pentenyl glucosinolate per gram of air–dry, oil–free solid.

Canola oil is widely used as cooking oil, salad oil and in making margarine. Commodity canola oil is low in saturated fatty acids, which may have adverse effects on blood cholesterol levels. Hence, replacing highly saturated oils (i.e., animal fats, cottonseed) with canola oil in diet is a good option for a healthier life style. Some other current and potential non–food uses of canola oil include hydraulic fluid, biodiesel, cosmetics, engine oils, heat transfer oils, demolding agents, solvents, lubricants and printing ink formulations.
