Abstract: A process for amino acids was devreloped by acids hydrolysate of silkworm pupa proteins and silkwormpupa proteins were obtained from the fresh silkworm pupa by de-fat and chemically oxidixing de-peculiar smell .Theproducts of this process were examined chemically and sensor-ially and de-fat (88%)and proteins content in thesilkworm pupa proteins 86%,and amino acids by acids hydrolysate silkworm pupa proateins (60%) .The de-fatendthe de-peculiar smell method has been applied ror patent.

Key words: Silkworm pupa protein amino acids acids hydrolysate
