hydrolysate in water to obtain concentration of 0%, 0.5% and 1%
w/v representing the score of 0, 2.5 and 5, respectively. To test
the samples, all fish protein hydrolysates (0.75%) were placed in
a sealable plastic cup and heated at 60 C in a temperature
controlled water bath for 5 min before serving. The panelists were
asked to open the sealable cup and sniff the headspace above the
samples for determining fish odour. To evaluate the fishy flavour,
panelists were asked to taste the sample and rinsed their mouth
between different samples.
