Yellowfin tuna (Thunnus albacares) steaks were light smoked using coconut husks and packed in indigenously developed retort pouches of size 17 cm × 11 cm, having a configuration of 12.5-µm polyester/12.5-µm aluminum foil/80-µm cast polypropylene. Hot refined sunflower oil and 2% brine solution were used as the filling medium. Processing was done to an Fo value of 10 in an overpressure autoclave with a facility for rotation. Heat penetration characteristics of the product were studied using an Ellab CTF 9008, an Fo-cum-cook value integrator. Different batches of tuna were processed in oil and brine media to an Fo value of 10 at 2, 4, 6 and 8 rpm, and compared the results with that obtained from a stationary retort. Increase in speed of rotation gave a reduction in total process time and a lower cook value. Heat penetration was lowest for the stationary retort and increased with the speed of rotation in both the oil and brine media. Heat penetration was faster in the brine medium for the same rotation speed and stationary retort when compared with that in the oil medium.
