Abstract
A process has been developed for the preparation of shelf-stable, ready-to-eat (RTE) shrimps using a combination of hurdles. The
hurdles employed to cooked marinated shrimps included reduced water activity (0.8570.02), packaging and g-irradiation (2.5 kGy).
Microbiological analysis revealed a dose dependent reduction in total viable count and Staphylococcus species. In nonirradiated
samples a visible mold growth was seen within 15 days of storage at ambient temperature (2573 1C). No significant changes in
textural properties and sensory qualities of the product were observed on radiation treatment. These RTE shrimps were
microbiologically safe and sensorially acceptable even after 2 months of storage at ambient temperature.
