Subsequent reactions to generate aroma compounds were carried
out with selected slurries of the fish powder hydrolysates
(FPHs) based on the degree of hydrolysis and free amino acid
content. Aliquots of FPHs (0.2 mL) were mixed, homogenised with a
glucose solution (0.05 mL, 80 mmol/mL) in glass reaction vials and
freeze-dried. Glycerol (500 mL) was added to each freeze-dried
sample to facilitate homogenisation while fish oil (1.5 g/100 g)
was added to some of the samples according to the experimental
design (Table 2)
