Extracted flake products protein isolates

Method of production soybean processing first the oil and husk are removed, the remaining flakes are subjected to protein extraction pH control permits Isolation of required range of protein molecules next step involves chemical modification, which Imparts required properties grades obtained In this technology include unhydrolyzed grades, hydrolyzed grades, carboxylated soy protein, and proteinates ... 

The complete removal of lipids is used as an additional precautionary measure in order to obtain an off-flavor-free product, particularly in the case of production of protein isolates. For example, the lipid residue which remains in soy flakes after hexane solvent extraction (cf. 14.3.2.2.1) is removed by extraction with hexane-ethanol 82 18 v/v. 

Sodium Bisulfite Replaces Sulfur Dioxide in Soy Processing Solae Company, dba DuPont Soy Polymers (formerly Protein Technologies International), in Louisville, KY, extracts protein from soybean flakes for use in products, such as soy flours, concentrates, and isolates. The facility formerly used anhydrous sulfur dioxide to bleach products, stabilize drying, and lower pH. To improve safety, Solae switched to sodium bisulfite, a less acutely hazardous chemical. The change improved the safety of more than 37,000 residents and others who work in Louisville.
