    Mechanical Soy Processing: An Environmentally Friendly Method

    Mechanical processing methods, which are chemical free, existed prior to the wide spread use of chemical processes which were adopted based on ability to remove 100% of oil present in soybeans. Early mechanical methods, used presses to "squeeze" the oil from the soybean, however oil extraction rates were 50% at best, and often times generated excessive heat causing damage to the vital nutrients. In late 1980's Insta-Pro introduced a branded process called ExPress® (Extrusion Pressing

    OIL EXTRACTION METHODS Five methods can be used to separate the oil from the seeds; organic solvent extraction, mechanical pressing, aqueous, enzymatic, and supercritical fluid extraction (Dunford, 2001). Mechanical Extraction In mechanical pressing, mechanical pressure forces the oil out of the seed. The efficiency of this method is low.

    Profitability Analysis of Soybean Oil Processes

    In the soybean refining process, extracting oil and concentrating protein contents are the two main purposes. The oil extraction is seen as the first step of soybean applications. The mechanical pressing technique, using pressure and heat to disrupt oleosome structure, was first used in the industry in the early 1940s . However, low oil yield, oil darkening, and oil deterioration resulted from over-heating are the major disadvantages of mechanical pressing process.

    Professional Process of Soybean Oil Production

    There are two methods of soybean oil production, one is mechanical way, which is a traditional method that use screw press machine to squeeze oil out from seeds and kernels; the other way is chemical method that extract oil with solvents. Both two oil production methods have advantages and disadvantages. The previous one is natural and healthy but the oil yield is much lower, however, oil yield of the solvent extraction method is much more higher.
