Effect of refrigerated storage on the biochemical parameters of stored Indian mackerel (Rastrelliger kanagurta) in solar operated indigenously developed fish vending unit

Gayatri Pandey, CV Raju, and Jagpal

The objective of this study was to investigate the effects of refrigerated storage on the biochemical and sensory changes (overall acceptability) of Indian mackerel (Rastrelliger kanagurta) fillets during a 8 day period at +3-6 °C by using solar energy as the energy source of the unit. The vending unit consists of 3 different compartments to keep different sized fishes separately and also have the display facility. The samples were collected from the mangalore landing centre in very fresh condition and the evaluation on the biochemical and sensory attributes was done on every alternate day interval upto 8 days. The NPN content of mackerel decreased significantly (p<0.05) to 3.5 mg% and TVBN,TMAN, PV,TBARS and FFA content increased significantly to 33.13 mg%, 8.40 mg%, 21.28 meqO2/kg of fat, 3.93 mg malonaldehyde/ Kg of meat, 24.01% oleic acid respectively. Whereas, pH reached 6.21 and AAN reached 0.37 mg% on the 8th day but the values did not showed any significant difference with the increase in storage days.
