Storage stability of vacuum packaged turkey meat sausages incorporated with carrot and radish paste during refrigerated storage

Abstract

The present study was intended to evaluate the shelf life of vacuum packed turkey meat sausages incorporated with raw carrot paste (RCP) and raw radish paste (RRP) each at 10% level under refrigeration (4±1 °C) for a period of 25 days. The sausages were evaluated for physico-chemical, microbiological and organoleptic quality at an interval of 5 days during refrigeration storage. The quality parameters were significantly (P< 0.05) affected due to the incorporation of raw carrot paste (RCP) and raw radish paste (RRP) and also due to refrigeration storage. The results revealed that there was a significant (P< 0.05) increase in the pH, TBARS value and Tyrosine value as storage progressed from 0-25 days. However, the values were well below the threshold level of spoilage. Standard plate counts increased significantly (P< 0.05) as storage period progressed from 0-25 days. Psychrophilic counts were not detected in the control and treated sausages at 0th day, afterwards the psychrophilic counts increased significantly (P< 0.05) as storage period progressed from 5-25 days. Yeast and mould counts were not detected in any of the products throughout the entire storage period. Sensory evaluation revealed a decrease in the sensory scores with the advancement of storage during entire storage period. Based on the results, it can be concluded addition of raw carrot paste (RCP) and raw radish paste (RRP) each at 10% level would not only extends the shelf life by protecting the product longer against oxidative rancidity but also had higher acceptability than control and their use in meat products can enhance the shelf life up to 25 days under refrigerated storage without undesirable changes.
