FAQ

  • Why is rapeseed cooked or tempered?
  • Oilseeds are cooked or tempered to denature proteins, release oil from the cells and inactivate enzymes. For example, rapeseed contains the enzyme myrosinase. This enzyme catalyzes hydrolysis of glucosinolates which are naturally present in rapeseed.
  • What factors affect the design of oilseed handling facilities?
  • Physical properties of the seeds, such as size, shape, bulk density and flowability affect the design of oilseed handling facilities. For example, canola, rapeseed, delinted cottonseed, soybean and sunflower have very good flowability. They are usually stored in vertical cell-like storage bins.
  • How are seeds prepared for oil extraction?
  • Unit operations for preparation of seeds for oil extraction vary slightly depending on the physical properties and oil content (Figure 1). However, most oilseeds go through the process of cleaning, drying dehulling, size reduction, flaking cooking and tempering.
  • Do oilseed husks contain oil?
  • Hulls and shells of oilseeds do not contain a significant amount of oil (less than 1 percent). Most oilseeds need to be separated from their outer husk or shell prior to oil extraction. Dehulling also is referred to as shelling or decorticating.
  • How do oilseed storage bins work?
  • Most oilseed storage bins are equipped with aeration ducts and ventilation blowers to cool the seeds. Since oxidation reactions are aerobic processes, a low oxygen atmosphere in storage bins helps to slow down oxidation and quality deterioration.
  • Can you use a grain dryer for oilseeds?
  • Large, vertical, open-flame grain dryers can be used for oilseeds as well. These dryers have multiple columns of oilseeds which slowly migrate downward. The upper portion of the column is used for drying and lower section is for cooling. The amount of hull on oilseeds varies significantly.
