  • What is the average reduction in sunflower seed oil during refining process?
  • Total average reduction for sunflower seed oil samples during refining process was 32.9%. The level was about 13.8 mg/100 g in crude sunflower oil and about 9.2 mg/100 g in refined sunflower oil. Losses (%) of minor components during each step pf the refining process.
  • What is the purpose of Refining sunflower oil?
  • The purpose of refining sunflower oil is to convert the crude oil, which has a high acidity level and/or organoleptic defects, to make it suitable for human consumption. The refining is also aimed at removing contaminants as pesticides and process solvents.
  • What are the steps of sunflower oil extraction & refining?
  • Figure 1 represents schematically the main steps of sunflower oil extraction and refining. There are five main stages where there is a potential leak of minor components: Degumming, neutralization, bleaching; winterization and deodorization. In industries we can find several adaptations of this simplified schema.
  • What is sunflower oil mechanical extraction?
  • Sunflower oil mechanical extraction is the first step to obtain crude oil, after filtration cold press oil is obtained. On the other hand the residual oily cake is going to be submitted to a solvent extraction and after five successive stages refined oil is obtained.
