The invention relates to the technical field of single-
cell protein processing, in particular to a method for producing aerobic type single-
cell protein through an autolysis process. The method comprises the steps of
settling concentration, centrifugal
dewatering,
drying, sterilization and smashing and packaging, wherein autolysis and
drying are carried out on materials with the
moisture content of 78 percent to 85 percent obtained after the step of centrifugal
dewatering in sequence. The autolysis process is adopted in the process and the manufactured product, autolytic enzymes fully decompose
macromolecule nutrients and
cell walls in the autolysis process, and high-content
free amino acid and free
nucleotide can be generated through autolysis. Meanwhile,
polysaccharide of the cell walls is decomposed, so that cells are permeable, it is guaranteed that active substances can flow out of the cells, and therefore the active substances can be directly absorbed and utilized by animals. Autolysis is carried out after centrifugal
dewatering, and the high efficiency of autolysis can be ensured; the content of
moisture needing to be removed in a
drying process after autolysis can be reduced, and therefore drying cost is lowered.
