Abstract:  As the by-product of the deep processing, the skin of tilapia was adopted to research the water-risen technique. The optimum conditions were obtained by assays. The best water-risen effect was acquired at 25 ℃, soaked 6 h with 0.0225 g/L aqueous alkali, blanched 30 s at 90 ℃ constantly, bleached by the ice purified water till pH7, it could be stored at 4 ℃ over 30 d. The water-risen tilapia skin with crispy and springy quality was produced by those techniques; it might help in the deep processing of tilapia skin usage technology.
