Abstract:

The effect of spray application of commercial liquid smoke on the microbial, textural, biochemical and sensory properties of Catla fillets was evaluated. Catla fillets were soaked in 5% brine solution for 30 min and then divided into three lots. One quantity was packed in pouches of size 15 x 22 cm made of 12 μ polyester laminated with 300 gauge Low-density polyethylene and kept as control. Remaining fillets were sprayed with a pre-diluted commercial liquid smoke (Red Arrow International) for 2 h in a smoker (Kerres CS700EL) with a flow rate of 1.5 l/ hr. The samples were then surface dried to remove the excess liquid smoke residue which had condensed on the surface. Half of the samples were vacuum packed and rest were air sealed. The untreated samples were kept as control. All the three lots were stored at 2?1?C. The fillets were subjected to biochemical, textural, microbiological and sensory evaluation at regular intervals. Results showed that the application of liquid smoke resulted in lowering the total microbial count and improved the textural properties. Biochemical parameters such as Total volatile basenitrogen (TVB-N), Trimethylamines (TMA-N), Thiobarbituric acid (TBA) value were found to be lower in liquid smoke treated samples during the storage period. Liquid smoke treated samples showed superior shelf life than control samples.
