Abstract
The present invention describes a bio-based process to produce high quality protein concentrate (HQPC) by converting plant derived celluloses into bioavailable protein via aerobic incubation, including the use of such HQPC so produced as a nutrient, including use as a fish meal replacement in aquaculture diets.
Claims3
A method of producing a soy protein concentrate comprising:
- a. optionally, extruding plant material at above room temperature to form a mash and transferring the mash to a biorector;
- b. adding one or more cellulose-degrading enzymes to release sugars into the mash in the bioreactor;
- c. inoculating the enzyme treated or untreated mash with at least one microbe, which microbe converts released sugars into proteins and exopolysaccharides;
- d. precipitating the resulting proteins, microbes, and exopolysaccharides with ethanol, a flocculent, or a combination thereof;
- e. recovering the precipitated material via hydrodynamic force;
- and
- f. drying said precipitated material, wherein said soy protein concentrate comprises proteins, microbes, and exopolysaccharides.
