Abstract

A fermentation product comprising a nonviable edible proteinaceous mass derived from a non-toxic fungal mycelium of a non-toxic strain of Fusarium preferably selected from the group consisting of Fusarium graminearum, Fusarium solani and Fusarium oxysporum possessing a reduced level of RNA of below 4%.

Claims

1. An edible protein-containing substance comprising a non-viable edible non-toxic fungal mycelium of a non-toxic strain of Fusarium possessing a reduced level of RNA of below 2%, and being further characterized by improved ease of processing to a form suitable for food use and an essentially white color such to make the protein-containing substance compatible with food use and a filamentous structure.

2. An edible protein-containing substance comprising a non-viable edible non-toxic fungal mycelium of a non-toxic strain of Fusarium selected from the group consiting of Fusarium graminearum, Fusarium solani, and Fusarium oxysporum possessing a reduced level of RNA of below 1.5%, and being further characterized by improved ease of processing to a form suitable for food use and an essentially white color such to make the protein-containing substance compatible with food use and a filamentous structure.

3. An edible protein-containing substance comprising a non-viable edible non-toxic fungal mycelium of a non-toxic strain of Fusarium graminearum Schwabe deposited with the Commonwealth Mycological Institute and assigned the number IMI 145425 (A.T.C.C. No. 20334) possessing a reduced level of RNA of below 1.29%, and being further characterized by improved ease of processing to a form suitable for food use and an essentially white color such to make the protein-containing substance compatible with food use and a filamentous structure.

4. An edible protein-containing substance comprising a non-viable edible non-toxic fungal mycelium of a non-toxic strain of Fusarium, said product having a filamentous structure and possessing a reduced level of RNA of between approximately 0.8% and approximately 0.43%, and being further characterized by improved ease of processing to a form suitable for food use and an essentially white color such to make the protein-containing substance compatible with food use.

5. An edible protein-containing substance in the form of a cohesive sheet comprising a non-viable edible non-toxic fungal mycelium of a non-toxic strain of Fusarium, said product having a high net protein utilization value of the order of 41 or above based on total nitrogen and possessing a reduced level of RNA of between approximately 0.67% and approximately 0.43%, and being further characterized by improved ease of processing to a form suitable for food use and an essentially white color such to make the protein-containing substance compatible with food use and a filamentous structure.

6. An edible protein-containing substance comprising a non-viable edible non-toxic fungal mycelium of a non-toxic strain of Fusarium graminearum Schwabe I.M.I. 145425 (A.T.C.C. No. 20334), said product having a high net protein utilization value of the order of 52 or above based on total nitrogen and possessing a reduced level of RNA of approximately 0.43%, and being further characterized by a white color such to make the protein-containing substance compatible with food use and a filamentous structure, and being capable of processing by vacuum filtration in the form of a washed moist product suitable for food use.
