Abstract

---

Aim: The present study was conducted for the development of ready-to-eat Vawksa rep (smoked pork product) and to study the synergistic effect of curing ingredients and vacuum packaging on the physico-chemical and storage quality during refrigerated storage at (4°C±1°C) for 15 days.

Materials and Methods: Four different batches of Vawksa rep samples were prepared, i.e., T-1 (uncured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min), T-2 (uncured, cooked, and smoked simultaneously at 120°C for 45 min), T-3 (cured, first cooked at 121°C for 15 min, and then smoked at 120°C for 30 min), and T-4 (cured, cooked, and smoked simultaneously at 120°C for 45 min).

Results: Cooking yield was significantly higher (p<0.05) for the T-4. The pH of T-3 and T-4 samples was significantly higher (p<0.05) on day 15. The tyrosine value of all the samples increased significantly (p<0.05) among the different days of analysis. Thiobarbituric acid value was significantly (p<0.05) lower in T-3 sample both at the beginning and at the end of storage period. In microbiological profile, total plate count was lower in T-3 and T-4 than T-1 and T-2. However, Escherichia coli count was negative for T-3 and T-4 samples throughout the storage period. Among sensory attributes, T-3 and T-4 samples registered superior scores for color, flavor, texture, juiciness, and overall acceptability.

Conclusion: Furthermore, Vawksa rep (smoked pork product) could be prepared easily with little technology up-gradation and with a negligible escalation of production cost.
