The oxidative stability and minor constituents of three cold-pressed low erucic acid rapeseed oils and three virgin olive oils were compared. The rapeseed oils were more easily oxidized, in part due to their higher contents of polyunsaturated fatty acids. The rapeseed oils were rich in γ-tocopherol and had low initial peroxide values (PVs), but their hydrophilic phenol content was low, only 3

Solvent‐extracted canola oil exhibited the highest free phytosterol content (178 mg/100 g), while RBD canola oil only had 129 mg/100 g of free phytosterols. While cold‐pressed canola oil had the lowest amount of polyphenols, traditional refining resulted in almost complete removal of polyphenols from canola oil.

What is cold pressed rapeseed oil? Hillfarm Oils

How is cold pressed oil made? Rapeseed is small and black, much like a poppy seed, with a golden-yellow centre. The oil is locked up in the carbohydrate at the centre of the seed, and cold pressing is the method we use to extract this oil, by gently squeezing it out of the seed. The process all starts in our fields. Once our rapeseed has fully
