Which method of oil removal is used in soybean processing?
Mechanical pressing and solvent extraction are the two primary methods of oil removal used in soybean processing. The mechanical process, with hydraulic pressing and continuous screw pressing techniques, was used before the development of solvent extraction [ 9 ].
How is soybean processed?
Modern soybean processing starts with solvent extraction to obtain crude oil and defatted meal. Most defatted meal is used for animal feed and only a small portion is further processed into different types of soy protein products for human consumption (see Chapter 8). Crude oil contains variable amounts of nontriglyceride materials.
Which solvent is used in soybean oil production?
Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , . This solvent has a high solubility for oil extraction, availability, low price, low boiling point, and heat of vaporization .
What is the preprocessing process of Raw soybean?
The preprocessing of the raw soybean includes drying, storage, mechanical cleaning, dehulling, and flaking. The solvent is a mixture of hexane isomers ( n -hexane, methyl-pentane, methyl cyclopentane, and dimethylbutane) rich in n -hexane (60%), and the extraction occurs in a countercurrent percolation system.
