Claims
- 1. Process for producing food proteins, comprising the steps of: cultivating the fungus Trichoderma Album (I-032) in a nutrient media at a temperature below 28.degree. C., the pH of said media being kept at a value between about 3.7 and 4.8; the nitrogen content (atomic N) of said media being adjusted to a value of about 4 to 5%, with respect to the dry material; the dissolved oxygen content being from about 6 to 10 mg/l; said cultivation being carried out with stirring which does not cause lysis of the fungus; and under conditions such that foaming is avoided.
- 2. Process according to claim 1, wherein the nutrient media is derived from agricultural products, agroalimentary industry rejects or from protein substrates to be enhanced in value.
- 3. Process according to claim 2, wherein the agricultural products are:
- (a) flours selected from the group consisting of wheat, rye, corn, barley, oats and peas;
- (b) tubers and roots selected from the group consisting of potatoes, Jerusalem artichokes, manioc, sweet potatoes, beetroots, beetroot molasses, beetroot pulp, carrots and swedes;
- (c) the pulps and teguments of fruits selected from the group consisting of bananas, pineapples, oranges and apples;
- (d) marcs; and
- (e) fibrous products selected from the group consisting of bagasse, straw and wood.
- 4. Process according to claim 2, wherein the agroalimentary industry rejects are: bird droppings; liquid manures; household wastes; residual waters; effluents from preserving plants, protein plants or distillery vinasses; corn steep; diffusion waters from sugar factories; or products derived from marine creatures selected from the group consisting of fish and crustacae.
- 5. Process according to claim 4, wherein the products derived from marine creatures are the press liquors and concentrates of soluble fish proteins.
- 6. Process according to claim 1, wherein the temperature is comprised between 24.degree. and 28.degree. C.
- 7. Process according to claim 2, wherein the protein substrates are beetroot pulps or soluble fish protein concentrates.
- 8. Protein products obtained by the process according to claim 1.
- 9. Protein products according to claim 8, constituted by proteins from the filamentous micro-organism, Trichoderma Album and containing 50 to 65% of proteins (N.times.6.25).
- 10. Protein products according to claim 8, constituted by residual proteins from the nutrient media in admixture with Trichoderma Album proteins.
