title: Development of designer chicken shred with response surface methodology and evaluation of its quality characteristics.
abstract: Meat is considered to be an excellent source of protein, essential minerals, trace elements and vitamins but negative concerns regarding meat consumption and its impact on human health have promoted research into development of novel functional meat products. In the present study Rice bran oil (RBO), and Flaxseed oil (FSO) were used for attaining an ideal lipid profile in the product. The experiment was designed to optimise the RBO and FSO concentration for development of product with ideal lipid profile and maximum acceptability by the application of central composite rotatable design of Response surface methodology (RSM). Levels of RBO and FSO were taken as independent variables and overall acceptability (OAA), n-6 and n-3 fatty acids as responses. Quadratic fit model was found to be suitable for optimising the product. Sample with RBO (20.51 ml) and FSO (2.57 ml) yielded an OAA score of 8.25, 29.54 % of n-6 and 7.70 % of n-3 having n-6/n-3 ratio as 3.8:1. Optimised product was analysed for physico-chemical, sensory and microbial profile during storage at 4 ± 1 °C for 30 days. Increase in the lipid oxidative parameters was observed during storage but it was not significant (p < 0.05). Studies revealed great potential of developing functional poultry products with improved nutritional quality and good shelf stability by incorporating RBO and FSO.
