  • What fatty acids are in rapeseed?
  • Fatty acid compositions of sunflower, rapeseed, mustard, peanut and olive oils. Oleic acid (C18:1n9c) content had the highest ratio, and it ranged between 36.65 and 68.85%. Rapeseed and olive oils include higher amount of oleic acids than those of sunflower, peanut and mustard oils.
  • How many markers are there in sunflower rapeseed oil?
  • The set of 29 markers involving 13 markers for sunflower, 8 for rapeseed, 5 for sesame and 3 for flaxseed oil was determined. Markers were annotated to the level of retention times and characteristic ions, i.e. accurate masses of precursor and fragment ions. The structure of these compound are yet to be elucidated.
  • Is sunflower oil cheaper than rapeseed oil?
  • The last 3?years show a lasting inversion of this tendency, the sunflower oil FOB NW Europe being 41 to 48?US$/ton cheaper than soybean oil and 104 to 185?US$ cheaper than rapeseed oil (yearly average, October to September, source Oil World, 2019). It kept a premium between 30 and 130?US$ compared to palm oil.
  • How much caffeic acid is in rapeseed oil?
  • Samples from Poland contained 1.14 mg caffeic acid per 100 g, and the concentrations in sunflower and rapeseed oil were 1.20 and 1.31 mg CAE/100 g (CAE, caffeic acid equivalent), respectively [ 37 ]. Table 2. Trolox equivalent antioxidant capacity (TEAC), total phenolic content (TPC) and total carotenoid content (TCC) of the oil samples.
  • Does adding sunflower oil to rapeseed reduce phenolic content?
  • In the light of our findings, adding sunflower oil to sesame or flaxseed oil will apparently reduce the total phenolic content, whereas adding sunflower or sesame oil to rapeseed or flaxseed will result in decreasing the total content of carotenoids.
  • How to prepare rapeseed oil?
  • At present, the most frequently utilized methods for the preparation of rapeseed oil are either mechanical pressing or solvent extraction (Ye & Liu 2023 ), such as hexane extraction (HE), which has the advantages of a large processing capacity and low production cost ( Guo, Wan & Huang 2019 ).
