Contains.

The main component of olive oil itself is oleic acid, which is 18-carbon monoacid (18:1). If cis-trans isomerization occurs under the action of heat, the trans fatty acids formed are similar to the trans oleic acid in hydrogenated vegetable oils.

This cis-trans isomerization reaction that occurs during the heating process not only occurs in olive oil, but also in other fats and oils, and under reasonable technology and non-frying cooking conditions, the content will not be too high. , if a product contains less than 0.3% trans fatty acids, it can legally be labeled as zero.

Notes:

1. Do not stir-fry at high temperatures: some trace elements contained in olive oil belong to multiple categories.
