manufacturing process of products rich in protein and vitamins from a solid substrate, rich in starch amylacees materials and products obtained

摘要

A food prod. rich in protein and vitamins is obtd. from a starchy material by the following dry fermentation process. Cereal grains are steeped in a nutritive soln. so that they absorb sufficient to maintain the growth of microorganisms, then the moistened grains are crushed to burst the pericarp and seminal tegument of the grains; the resultant mass is then seeded with a microorganism. Development then takes place at 20-30 degrees C whilst the mass is aerated in a fermenter. The mass obtd. is then dried. The microorganisms are chosen from Actinomycetes, Siphomycetes and Septomycetes provided that the strains are amyloltic, the strains are filamental fungi not producing multiplication or conservation spores, that their mycelium has about a 40% protein content on a dry basis, and finally that the compsn. of the protein amino acids is similar to soya or FAO protein. The prod. may be directly used for animal feeds and the proces avoids the high cost of a liq. fermentation process.
