Preparation And Dehulling
The first step in the production of soybean oil is to prepare the bean for dehulling. Magnets are used to remove metal and screened to clear away impurities which can interfere with the dehulling process. The hulls are removed to increase the protein content of the meal and promote the efficacy of the solvent extraction process. Mechanical rollers are used to roll soybean into thin flakes which split the cells containing oil.
The process of soybean oil extraction makes use of hexane solvents to clean the oil from the soybean flakes.
After the oil has been removed by the solvent, the solvent must be separated from both the flakes and the soybean oil. The flakes are heated and steamed to strip and recover the residual solvent. To extract the soybean oil distillation method is used to recover the solvent. The desolventized flakes are a by-product and source of good protein. The oil is further refined from crude to an edible source.
Refining And Processing
The desolventized oil is further processed to obtain the edible oil to enhance the flavour, colour, odour and solidity with the processes that neutralise, bleach and deodorize the oil. This refining process clears away the contaminants like free fatty acids, phosphatides and pro-oxidants.
The soymeal obtained after the extraction of the oil is further processed to produce value-added goods.
