Abstract
The present disclosure describes a system for the commercial scale extraction of isoflavones from soybean meal. The system includes an optional grinder, an extraction component, a solid-liquid separation component, an acid hydrolysis component, a neutralization component, and a purification component. Also provided are methods of commercial scale extraction of one or more isoflavones from soybean meal. The method includes extracting an isoflavone glucoside from soybean meal, hydrolyzing the isoflavone glucoside to obtain an isoflavone aglycone, neutralizing the isoflavone aglycone, and purifying the isoflavone aglycone.
Claims20
A system for commercial scale extraction of an isoflavone from soybean meal, the system comprising:
- an optional grinder,
- an extraction component,
- a solid-liquid separation component,
- an acid hydrolysis component,
- a sieve component configured to reject soybean meal particles greater than about 250 μm in size,
- a neutralization component in fluid communication with the acid hydrolysis component, and
- a purification component,
- wherein the system extracts about 500 to about 1000 kg//h of soybean meal.
A method of commercial scale extraction of one or more isoflavones from soybean meal, the method comprising:
- extracting an isoflavone-glucoside from soybean meal at a soybean meal feed rate of about 500 to about 1000 kg//h,
- hydrolyzing the isoflavone glucoside to obtain an isoflavone aglycone,
- neutralizing the isoflavone aglycone, and
- purifying the isoflavone aglycone.
