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
