Aim:The present study was conducted to determine efficacy of edible coating of carrageenan and cinnamon oil to enhance the shelf life of chicken meat stored under refrigeration conditions.Materials and Methods:Chicken breast was coated with carrageenan and cinnamon oil by three methods of application viz., spraying brushing and dipping. The coated meat was evaluated for drip loss, pH, thiobarbituric acid number (TBA), tyrosine value (TV), extract release volume (ERV), Warner-Bratzler shear force value (WBSFV), instrumental color, microbiological, and sensory qualities as per standard procedures.Results:There was a significant difference observed for physicochemical parameters (pH, TBA, TV, ERV, drip loss and WBSFV) and microbiological analysis between storage periods in all the samples and between the control and treatments throughout the storage period but samples did not differed significantly for hunter color scores. However, there was no significant difference among three methods of application throughout the storage period though dipping had a lower rate of increase. A progressive decline in mean sensory scores was recorded along with the increase in storage time.Conclusion:The carrageenan and cinnamon edible coating was found to be a good alternative to enhance the shelf life of chicken meat under refrigeration conditions. It was also observed from study that dipping method of the application had comparatively higher shelf life than other methods of application.

Response surface methodology (RSM) is a mathematical and statistical technique for testing multiple process variables and their interactive, linear and quadratic effects, and useful in solving multivariable equations obtained from experiments simultaneously. In present study optimum meat level and processing conditions for development of shelf stable chicken meat noodles was determined using central composite design of response surface methodology (RSM). Effects of meat level (110-130 g); processing conditions such as steaming time (12-18 min) and drying time (7-9 h) on the water activity, yield, water absorption index, water solubility index, hardness, overall acceptability and total colour change of chicken noodles were investigated. The aim of present study was to optimize meat level and processing conditions for development of chicken noodles. The coefficients of determination, R 2 of all the response variables were higher than 0.8. Based on the response surface and superimposed plots, the optimum conditions such as 60 % meat level, 12 min steaming time and 9 h drying time for development of chicken noodles with desired sensory quality was obtained.

In present study, chicken fillets were coated with chitosan and cinnamon oil by three methods viz., spraying, brushing and dipping and shelf-life of coated meat were studied. Efficiency of coating material and three methods of application were determined through shelf-life studies of coated meat under refrigeration conditions (4±1°C). Based on the results of physico-chemical, sensory and microbial characteristics, spraying method had lower Tyrosine Value, Thiobarbituric Acid number, Standard Plate count, drip loss and higher sensory scores compared to other methods of application. Extract Release Volume and Water Holding Capacity decreased significantly (P less than 0.05) with storage period in all the samples. However spraying had comparatively lower values/or higher water holding capacity. Hunter color values did not differ significantly with storage and between treatments though brushing and dipping samples had comparatively higher yellowness and lightness but lower redness value. Spraying of chicken breast extended the shelf life of chicken breast upto 7 days compared to 3 to 5 days for control and treatments.
