Abstract: A fundamental pattern was proposed for the fast autolysis of shrimp ( Metapenacus enisi ) tissues through a series of study on factors of UV radiation, mineral ions, pH value and temperature for autolysis. The speed of autolysis was accelerated by appropriate UV radiation and sodium ions under the pH value of 7. 0- 7. 5 with a gradient temperature from 40 e to 65 e at 5 e / 30 min. The rate of hydrolysis for shrimp protein was more than 80% under the opt imal conditions mentioned above.
