  • How do you extract oil from a seed?
  • During crushing, 500 to 750 ml of water is added for a seed charge of 10-12 kg depending upon the dryness of the seed. The first extraction is warmed and added back to the mortar for speeding up the subsequent extractions. The oil is pressed out in 1.5-2 hr at a temperature of 38-40°.
  • What is the oil content of rapeseed & mustard?
  • The bold, sound and clean seeds yield a higher percentage of oil than the damaged ones or those containing higher content of refraction. The oil content of various types of rapeseed and mustard is as follows ¨C yellow sarson, 35.0-48.0% brown Sarson, 35.0-48.0% toria, 33.0-46.0%, lahi, 30-0-38.0% and rai, 30.0-42.0%.
  • How to extract essential oil from mustard seeds?
  • The first extraction is warmed and added back to the mortar for speeding up the subsequent extractions. The oil is pressed out in 1.5-2 hr at a temperature of 38-40°. The addition of water helps in the hydrolysis of thioglucosides (glucosinolates) present in the seeds, thus releasing the pungency producing essential oil of mustard.
  • How is rapeseed oil extracted?
  • Solvent extraction is the most modern method, in which the seed or cake is exposed to the action of a solvent like food grade n-hexane. The rapeseed oil so obtained retains the smell of the solvent used, and needs to be deodorized later. This method is very efficient leaving only about 0.5-1.0 per cent oil in the residue.
