Development of steaks by improved - technology and its process optimization.

The present study embarked on the objective of optimizing improved - processing condition for development of ready-to-cook steaks with extended shelf-life using response surface methodology. For the development of improved - cooked product, steaks were treated with additional hurdles in various combinations for optimization. Based on the study, suitable combination of chitosan and spices was selected which enhanced antimicrobial and oxidative stability of the product. The Box-Behnken experimental design with 15 trials per model was adopted for designing the experiment to know the effect of independent variables, namely chitosan concentration (X), cooking time (X) and cooking temperature (X) on dependent variable i.e. TBARS value (Y). From RSM generated model, the optimum condition for - processing of steaks were 1.08% chitosan concentration, 70.93 °C of cooking temperature and 16.48 min for cooking time and predicted minimum value of multiple response optimal condition was Y = 0.855 mg MDA/Kg of fish. The high correlation coefficient (R = 0.975) between the model and the experimental data showed that the model was able to efficiently predict processing condition for development of - processed steaks. This research may help the processing industries and fish farmer as it provides an alternative low cost technology for the proper utilization of .
