In general, the dried squid was consumed after rehydration or roasting. According to suggestion of customer, there were two defects. The first, the texture of conventional soften squid with alkali treatment during rehydration will be losing its original flavor; the second, the roasting dried squid had character flavor, but its texture was too tough to unaccept. In order to improve the texture of dried squid mantle, the squid was treated with different concentration of papain and bromelain before drying. After treating and drying, it can obtain lower shear force and higher rehydration than untreatment. The shear force of squid, Sepioteuthis lessoniana, Loligo chinensis and Ommastrephes bartrami, can be decreased 7.0 ~ 25.9 ﹪, 6.5 ~ 31.2 ﹪and 2.2 ~ 19.4 ﹪, respectively; and its rehydration was increased 6.5 ~ 55.5 ﹪, 6.2 ~ 50.4 ﹪and 4.1 ~ 47.0 ﹪, respectively. According to sensory evaluation, squids, (Sepioteuthis lessoniana, Loligo chinensis and Ommastrephes bartrami), treating with 0.1 ﹪papain at 5℃ 24 hrs, 25℃ 4 hrs and 5℃ 12 hrs, respectively, for rehydration; and 0.1 ﹪bromelain at 25℃ 8 hrs, 0.5 ﹪papain at 5℃ 24 hrs and 0.1 ﹪bromelain at 25℃ 4 hrs, respectively, for roasting, had better color, tough, flavor and overall acceptability.
