Abstract

Abstract Soybean flakes or meal are extracted with two-phase liquid solvent system; one phase consisting essentially of one or more lipophilic solvents and the other phase consisting essentially of a mixture of water and one or more water-miscible solvents. Oil and non-proteinaceous materials are simultaneously extracted providing a soy protein concentrate product which is light in color and bland in taste.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 77 words
A process for simultaneously extracting oil and low molecular weight non-proteinaceous components of soybeans which comprises contacting full fat soybean flakes or full fat soybean meal with a liquid solvent system susceptible to separation into two phases, said solvent system containing a lipophilic solvent for soybean oil, water and a water-miscible solvent for low molecular weight hydrophilic-solvent soluble components of soybeans, separating the solvent system from the so-contacted soybean materials and drying the solid soybean residue material.
Claim 2
Dependent Claim 77 words
A process for simultaneously extracting oil and low molecular weight non-proteinaceous components of soybeans which comprises contacting full fat soybean flakes or full fat soybean meal with a liquid solvent system susceptible to separation into two phases, said solvent system containing a lipophilic solvent for soybean oil, water and a water-miscible solvent for low molecular weight hydrophilic-solvent soluble components of soybeans, separating the solvent system from the so-contacted soybean materials and drying the solid soybean residue material.
Claim 3
Dependent Claim 23 words
A process in accordance with claim 1, wherein contacting of said soybean materials with said liquid solvent system is conducted in countercurrent manner.
Claim 4
Dependent Claim 25 words
A process in accordance with claim 1, wherein the lipophilic solvent is an organic oil solvent, and the water-miscible solvent is an alcohol or acetone.
Claim 5
Dependent Claim 48 words
A process in accordance with claim 1, wherein the ratio of water to water-miscible solvent ranges from about 2:8 to 4:6 on a volume basis and wherein the ratio of lipophilic solvent to the water and water-miscible solvent ranges from about 1:2 to 2:1 on a volume basis.
