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

During mechanical extraction, the oil seeds are put between barriers and pressure is applied using hydraulic presses and screws to crush them and extract the oil out. While it requires extensively trained experts, it is the most economical way to extract oil out of oilseeds. The residual oil cake from the mechanical extraction process also has

Soybean Oil Extraction and Processing | SpringerLink
Soybeans are the dominant oilseed in both U.S. and world markets. During a typical year soybean production comprises over half the worldwide oilseed production ( Anonymous 1995 ). However, according to Dutton (1981) in the early 1940s, soybean oil was considered a poor quality oil, not suitable for food use, and more appropriate for use in

Extraction and separation of oils: the journey from distillation to pervaporation - ScienceDirect
In the petroleum industry, the process of extraction of crude oil is divided into primary, secondary, and tertiary phases. In the primary phase of oil recovery (e.g., using pumps or gravity drainage), approximately 10% of the oil is extracted. In the secondary phase, water or gas is injected into the well.

White flakes (WFs) are obtained from dehulled flaked soybeans by extracting oil with hexane and flash- or downdraft-desolventizing the (defatted) flakes, and WFs are the normal feedstock used to produce soy protein ingredients. Gas-supported screw pressing (GSSP) is a new oilseed crushing technology in which traditional screw pressing is combined with injecting high-pressure CO2, thereby

Whole soybean protein extraction processes: A review
The aqueous extract of whole soybean extraction is called soybase and it is mainly used for making consumer products containing both soy protein and soybean oil. Products like soymilk, soy-fruit beverages and tofu are produced by adding various ingredients to the soybase, such as flavours, gums, stabilisers, minerals, vitamins, sugars, fruit juices and/or coagulating agents in case of tofu.
