Abstract
Gelatin from yellowfin tuna Thunnus albacares dorsal skin was optimized for adhesive strength to plywood using surface response methodology of a central composite design with a dependent variable of adhesive strength Y kg f /cm2 and two independent variables of gelatin concentration X1 and hardening time X2 hrs From the above design a maximum adhesive strength of 4984 kg f /cm2 was obtained under the optimal treatment condition of 1585 gelatin concentration and 2568 hr hardening time The adhesive strength under optimum conditions was 5093 kg f /cm2 The adhesive strength of the tuna gelatin was shown to be superior to that of bovine and porcine gelatins which had adhesive strengths of 3475 and 349 kg f /cm2 respectively
