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.

- 21. A composition comprising a non-animal based protein concentrate, wherein the composition contains at least 55% protein content by weight, exopolysaccharides and contains oligosaccharides in an amount of between about 0.00 g/100 g to about 0.24 g/100 g on a dry matter basis.

35. A method of producing a non-animal based protein concentrate comprising:
-
a. optionally milling plant material; b. cooking said plant material at above room temperature to form a mash and transferring the mash to a biorector; b. optionally adding one or more enzymes to the mash in the bioreactor; c. inoculating the mash with at least one microbe, which microbe converts released sugars into proteins and exopolysaccharides; d. separating solids from liquids in the mash via hydrodynamic force; and e. drying said separated solids and evaporating the separated liquids. - View Dependent Claims (36, 37, 38, 39, 40, 41)

- 42. A composition containing up to 80% by weight of said non-animal based protein concentrate comprising at least 55% protein content by weight, exopolysaccharides and oligosaccharides in an amount of between about 0.00 g/100 g to about 0.24 g/100 g on a dry matter basis and up to 20% by weight of a mixture containing one or more compounds selected from the group consisting of amino acids, lipids, vitamins, minerals, enzymes, antioxidants, and combinations thereof.
- 43. A microbially converted composition comprising soy protein, wherein the composition contains at least 60% protein content, exopolysaccharides, and a microbe selected from the group consisting of Aureobasidium pullulans, Sclerotium glucanicum, Sphingomonas paucimobilis, Ralstonia eutropha, Rhodospirillum rubrum, Kluyveromyces spp, Pichia spp, Trichoderma reesei, Pleurotus ostreatus, Rhizopus spp and combinations thereof.
