The reactivity of peptides has hardly been studied and, unfortunately, many of the
studies comparing peptide reactivity with that of amino acids measured the rate of
browning to quantify the Maillard reaction. In general, the amount of browning has
been shown to increase with chain length of the peptide. However, the amount of
browning is not, per se, proportional to the conversion of amino acid or peptides, as the
degree of browning depends on the type of melanoidin formed during the Maillard reaction (de Kok & Rosing, 1994). Motai (1973) concluded that melanoidins from
peptides exhibited a darker degree of color than those from amino acids. When the
degree of sugar decomposition was measured it appeared that small peptides (up to 3
amino acid groups) are more reactive than the corresponding amino acids (de Kok &
Rosing).
