Abstract
(i) Fresh (control) and (ii) brined (dipped in saturated brine for 30 min) shark (Carcharias melanopterus) fillets (size 15 x 5 x 2.5 cm) were stored (a) in direct contact with ice, (b) in ice after packing in polyethylene bags, and copyright along with ice (1:1 ratio) in polyethylene bags for 16 days. Total N decreased gradually in (i) and (ii) when in contact with ice; the decrease was small when fish were packed in polyethylene bags. (ii) when out of contact with ice lost 60% of salt whereas in contact with ice all salt leached out in 16 days. Urea content decreased appreciably in shark packaged by methods (a) and copyright . The rate of increase of alpha-amino N was more when in contact with ice. Trimethylamine N and total volatile bases increased more in packaged fillets of (i). The bacterial count showed considerable difference only in the initial stages. On the basis of colour, flavour and texture (ii) copyright gave max. shelf life of 13 days.
