indicate the S0 differences between the treatments (Fig. 6).
Several studies on food protein structure-function relationships
have emphasized the importance of protein hydrophobicity
for protein functional properties after different treatments
and/or processes [43]. The number of short peptides is
expected to increase with increasing DH, which produces
more hydrophobic amino acids in terminal positions [1].
Thus, the S0 value differences can be attributed to the hydrophobic
amino acid levels [44, 45]. The hydrophobic amino
acid levels are related to the level of bitterness. Therefore,
more bitterness should be expected in hydrolysates at pH 7.0.
