Turkey skin, a byproduct of poultry processing, contains a significant amount of collagen that might be used to make non‐mammal gelatin. However, gelatin production from turkey skin has not yet been investigated. The present study aimed to determine the optimum gelatin extraction conditions from turkey employing the central composite design and response surface methodologies. The independent factors such as temperature (50, 60, and 70 °C) and time (5, 7, and 9 h) were optimized for three response variables: yield, gel strength, and foam expansion (FE).

With R² values of 0.8576 for yield, 0.8386 for gel strength, and 0.9283 for foam expansion, linear, quadratic, and respective models were used. The yield, gel strength, and FE actual values were found to be 15.36%, 396.61 g, and 40%, respectively. The optimum extraction conditions were found to be 62.90 °C for 6.84 h …
