The present study was undertaken to evaluate the effect of different levels of pumpkin on the quality characteristics of chicken sausages. The pumpkin was incorporated at three different levels viz. 6, 12 and 18 percent replacing lean meat in the formulation. The products were analyzed for various physicochemical and sensory attributes. pH, emulsion stability, cooking yield, crude protein, ether extract and ash content of the products showed significantly (p < 0.05) decreasing trend with increasing levels of incorporation of pumpkin however, there was a significant (p < 0.05) increase in the moisture and crude fibre content. Based on various parameters, 12 percent level of incorporation was optimized as best. Chicken sausages with optimum level of pumpkin along with control were aerobically packaged in LDPE pouches and assessed for storage quality under refrigerated (4 ± 1°C) conditions. The mean values of pH and all the sensory parameters showed significantly (p < 0.05) decreasing trend for both control as well as treatment samples whereas TBARS (mg malonaldehyde/kg) value, total plate count (log cfu/g) and yeast and mould count (log cfu/g) showed significantly (p < 0.05) increasing trend with storage. Coliforms (log cfu/g) were not detected throughout the period of storage. Thus, fibre enriched chicken sausages could be successfully stored for a period of 14 days at refrigeration temperature (4 ± 1°C) without any significant loss in quality.
