ABSTRACT: The effect of processing time on biochemical, sensory characteristics, and instrumental texture profiles
of “Shrimp Kuruma” in retortable pouches and aluminum cans with equal pack weight and lethality was studied.
Processing in pouches resulted in a 35% reduction in processing time compared to cans for equal lethality (F0 8.0).
Thermal processing resulted in a14%loss of water in canned samples compared to9%in pouched products. Thermal
processing resulted in an increase in the volatile compounds and a decrease in the oxidation products in both canned
and pouched samples. Products processed in pouches were rated as lighter in color, more succulent, and more
desirable in firmness compared to products in cans. Chewiness and hardness showed a significant difference (P <
0.05) between the 2 treatments.
