  • What are the different processing techniques of oilseeds?
  • Understanding of various processing techniques of oilseeds is very important. Pre-treatments like cleaning, dehulling, decortications, flaking and heat treatments assist to enhance the recovery and quality of oil during processing. Oil extraction methods including ghanies, hydraulic press, screw press and solvent extraction are discussed in detail.
  • How are stored oilseeds sorted?
  • The stored oilseeds are checked for soundness, impurities, moisture content and other milling characteristics. The parameters such as type and quality of impurities/foreign material, moisture content, quality of shrivelled/immature seeds, oil content, colour and acid/iodine value of extracted oil are considered for sorting.
  • How to extract oil from dried seeds?
  • The dried seeds are fed to the hydraulic press or screw press for crushing of seeds. Size reduction is important to rupture the cell walls to make the oil extraction easier. A high-pressure continuous screw press is used for oil extraction. The extraction of oil using screw press is termed as preprocessing.
  • How to extract oil from hulled kernels?
  • Winnowing process is used to separate the separated hulls from the kernels. To enhance the surface area, de-hulled kernels are ground to obtain a coarse meal. Grooved rollers or hammer mill can be used for this purpose. Heat treatment can be applied in the next step to facilitate extraction of oil. Screw press is used for pressing purpose.
