Zusammenfassung:	The invention discloses a preparation method of silkworm pupa protein peptide, and belongs to the technical field of silkworm pupa protein peptide. Comprising the following steps: S1, preparing silkworm chrysalis into silkworm chrysalis powder, and then performing deoiling and defibering treatment to obtain silkworm chrysalis protein powder; s2, performing enzymolysis treatment on the silkworm chrysalis protein powder, and then sequentially performing debitterizing, desalting and sterilizing treatment to obtain silkworm chrysalis protein peptide; wherein the debitterizing and desalting treatment is that the enzymatic hydrolysate passes through cation exchange resin and anion exchange resin in sequence; the cation exchange resin comprises strong acid cation exchange resin powder, modified basalt fiber, modified chitosan and modified PVDF (Polyvinylidene Fluoride); the modified chitosan is chitosan subjected to pore diameter expansion modification treatment; the modified basalt fibers are basalt fibers treated
