FAQ

  • QWhat is rapeseed oil refining process?
    ATowards this, the crude rapeseed oil needs refining treatments to remove undesirable ingredients and produce higher quality oils [ 5 – 7 ]. Traditional rapeseed oil refining processes generally involve four successive operations: neutralization, degumming, bleaching and deodorization.
  • QWhat are the adverse effects of crude rapeseed oil?
    APhosphatides, free fatty acids, odiferous volatiles, colourant, waxes and metal compounds, which are undesirable materials in crude rapeseed oil products, have adverse effects on physicochemical properties, sensory characteristics, and storage stability of the rapeseed oil.
  • QWhat's your advantage?
    AHonest business with competitive price and professional service on export process.
  • QAre there competing interests in rapeseed oil?
    ACompeting interests: The authors have declared that no competing interests exist. Rapeseed oil is a major source of vegetable oil in the world. Its production is estimated at 27.71 million metric tons, the third just behind palm and soybean oil, supporting the 2018 official data of United States Department of Agriculture.
  • QHow is rapeseed oil extracted?
    AA 200 mg of rapeseed oil was mixed with 4mL potassium hydroxide ethanol solution (2mol/L) and shaken in a water bath at 90°C for 1h for saponification. When samples were cooled down to room temperature, 5 mL of n-hexane and 1 mL of deionized water were added and mixed vigoursly to extract the unsaponifiable matter.
  • QDoes rapeseed oil differ after refining?
    ADifferences were considered statistically significant at P< 0.05. The AV, PV, p -AV of the rapeseed oil in varieties after each refining process are shown in Fig 1. The AV of five different kinds of crude rapeseed oils were from 2.15 to 3.59 mg KOH/g and decreased significantly after neutralization, ranging from 0.29 to 0.45 mg KOH/g.
  • QHow much tocopherol is lost in rapeseed oil?
    APrevious study reported the greatest losses of total tocopherol content in oils could be induced by physical refining (deodorization), amounting approximately to 20.2–27.1% [ 32 ], and the deodorization step would cause 7–90% losses of tocopherols in rapeseed oils [ 33 ].
