Edible Oil Refining Process

Canola oil processing

Canola oil processing is a complicated process. Following preconditioning, canola seeds are next crushed and flaked before being heated slightly. These processes help to maximize oil recovery. The canola flakes are then "prepressed" in screw presses or expellers to reduce the oil content from about 42% in the seed (on an 8% moisture basis) to between 16-20%. Screw pressing also compresses the flakes into more dense cakes (called "press cake") which facilitates oil extraction.

Cleaning section of the canola oil processing plant

graded seed is cleaned by a number of different methods including air aspiration, indent cylinder cleaning, sieve screening, or a combination of these. Cleaning ensures that the seed is free of extraneous plant and other foreign material which is referred to in the industry as "dockage". Seed generally contains less than 2.5% dockage following the cleaning process. Seed that has been cleaned is ready for subsequent export or for crushing into canola oil and meal.

Seed which will be processed for oil and meal is preconditioned using mild heat treatment, and moisture is then adjusted to improve subsequent oil extraction.

Press cake which results from seed processing is next subjected to one of two types of oil extraction to remove much of the remaining oil. Oil may be extracted using either hexane ("solvent") extraction or by "cold-pressing".

The introduction of canola oil

Canola is an oilseed crop that was developed from traditional rapeseed by Canadian plant breeders during the 1970s. It is grown widely across Canada, several European countries, and Australia, and to a lesser extent in the United States. Canola is distinguished from traditional rapeseed by the greatly reduced levels of fatty acids, erucic acid and anti-nutritional compounds called glucosinolates.
