Oil Trans Content (%)
Soybean* 0.4-2.1%
Walnut* 2.0-3.9%
Sunflower 1.1%
Canola* 1.9-3.6%
Olive 0.5%
PH soybean oil** 43.6-50.2%

A consequence of transforming some of the natural unsaturated fatty acids to trans-fat during the deodorization step is a reduction in the content of beneficial ω-3fatty acids.

  • Heating bleached canola oil at 220°C for ten hours reduces the content of linolenic acid by almost 20% (5). Keep in mind that canola oil sold in the supermarket still contains 9-11% natural ω-3linolenic acid.
