The collagen, gelatin from anglerfish skin have been parting extracted by using pepsin and alkali method. The technological parameter of the extraction were determined by orthogonal design. The composition of anglerfish skin and the amino acid composition of the collagen, the viscosity, color, IP and the amino acid composition of the gelatin were also analysed. The results showed that the optimum addition of pepsin was 1%（w/w）and the optimum ratio between fish skin and solvent was 1:10, extracting for 6 h at the temperature of 5. Under this condition, the rate of extraction of the collagen from anglerfish skin was 11.01 percent. Also under this condition of w%=0.2 (w/v), the optimum ratio between fish skin and solvent was 1:10, extracting for 7 d at the temperature of 10, the rate of extraction of the gelatin from anglerfish skin was 11.23. The paper was study on the synthetical using of the castoff from the processing of anglerfish to extracting collagen and gelatin. So the resources of anglerfish skin can be used reasonable, thus it can improve the processing of benefits and economic value. [Key words] Anglerfish skin; Collagen; Gelatin; Extracting 我国是
