  • extraction and processing of sunflower oil in south africa
  • How is sunflower oil extracted?
  • A volatile hydrocarbon like hexane is used as a solvent to extract the oil. CLEANING THE SEEDS: The harvested sunflower oil seeds are passed over magnets to subtraction any metal traces, and other impurities are getting rid of by cleaning sieve and destoners. Then the outer covering (hulls) of the seeds are removed to get pure seeds. DE-HULLING:
  • How has the South African sunflower industry changed over the past two years?
  • Over the past two decades, the South African sunflower industry has been characterised by volatile production levels with virtually no real growth while domestic demand for oilcake and vegetable oil has increased by approximately 40%. The imports of seed, oil and cake have gradually been increasing to meet the rising domestic demand levels.
  • How much sunflower seed oil is produced in South Africa?
  • Over the past three years South Africa produced around 300 000 tons of sunflower seed oil (SAGIS, 2011). According to a report on the Manufacturing of Oil and Animal Fat in South Africa by Who Owns Whom (Pty) Ltd the current processing capacity for sunflower seed is 1 442 000 ¨C 1 522 000 ton.
  • How long does sunflower seed oil last in South Africa?
  • The technology used for processing in South Africa is on par with foreign competitors (need to confirm). Sunflower seed oil has a shelve life of 12 months (FAO, 2010). The tables below lists the sunflower seed processing companies as well as the oilseed refineries and their capacities.
