The traditional method of extracting the oil is through the use of an oil expeller, a machine that crushes the rapeseed to squeeze out the oils. Clean the rapeseeds by removing any plant material and dirt still attached to the seeds. Place the rapeseeds in a flaking mill and turn on the mill.

Because of concern about environment, health, and cost, research into the production of rapeseed oil by aqueous extraction has been promoted. The advanced aqueous extraction method using a 1.5:10 water‐to‐rapeseed kernel slurry ratio without the addition of any chemical which was finally developed in this study recovered 94.73% rapeseed oil with high quality.

The objective of this thesis is to design a green process (aqueous extraction process) to extract rapeseed protein mixtures without de-fatting and to investigate the production of emulsions using this protein mixture. In the aqueous extraction process, only water was used as a solvent. To extract the protein mixture, alkaline extraction and isoelectric precipitation were applied. As a result, a protein

Versus common edible oils such as soybean oil (SBO), rapeseed oil (RSO), corn germ oil (CO), and sunflower oil (SFO), CAO contains high oleic acid concentration (almost 70%–86% of its fatty acid composition) [1,2].
The advantages and disadvantages of extracting edible oil

The process involves mixing ground and dehulled oilseeds in vats of hot water and skimming off the ail rising to the surface.4s The hot water flotation method for edible oil extraction from oilseed kernels is a traditional process used in the rural areas of many developing countries 49 The process is accomplished in five basic steps: { 1) heat conditioning of the seed, (2) grinding, (3) extraction by bailing, (4) oil recovery, and ($) drying.
Technical Feasibility of Aqueous Extraction of Rapeseed
Even though the rapeseed oil emulsion was least stable at minimum solubility of catalytic proteins (i.e. pH 4-5), more oil seemed to be absorbed in the residue, giving the minimum yield at this pH range. This was also observed by Hagenmaier et al., 1972, and Rhee et al., 1972, in aqueous extraction of coconut and peanut oil, respectively. Hence
An aqueous enzymatic extraction method was developed to obtain free oil and protein hydrolysates from dehulled rapeseeds. The rapeseed slurry was treated by the chosen combination of pectinase, cellulase, and β-glucanase (4:1:1, v/v/v) at concentration of 2.5% (v/w) for 4 h. This was followed by sequential treatments consisting of alkaline extraction and an alkaline protease (Alcalase 2.4L
