Linolenic acid canola oil

High oleic acid canola oil is another development pursued in Canada, the United States, Sweden, Australia, and elsewhere (137). As with low linolenic acid canola oil, the aim was to produce stable frying oil, which will not need hydrogenation and thus avoid fraui-isomers formation. The oleic acid content in oil from seed developed in Canada is at about 78%, whereas linoleic and linoleic acids are lowered to approximately 8% and 3% respectively (see Table 2). Saturated fatty acid content is unchanged from the standard canola oil. There is limited commercial seed production for export to Japan. Also, there is increasing acceptance of the oil in Canada and the United States. The frying performance in tests was found to be similar to... 

A study on the effect of heating on the oxidation of low linolenic acid canola oil at frying temperatures under nitrogen and air clearly showed that a significantly lower development of oxidation was evident for the low linolenic acid canola oil. Reduction in the linolenic acid content of canola oil reduced the development of room odor at frying temperatures.
