β¦ Synopsis
The Maillard reaction between tryptophan and glucose or xylose was studied as a function of pressure. Using model reactions, volumes of activation for the formation of the intermediate imine and the Amadori rearrangement and for the decomposition of the aminoketose were measured as -14, 8 and 17 cm'mol-', respectively. Pressure therefore accelerates the initial reactions but retards the formation of the final heterocyclic products and melanoidins. Oxygen was found to accelerate the latter reaction.

The activation and reaction volumes (βV /βV) were showing negative volumes of activation (βV Ο½ 0) whereas the others are slightly retarded (βV ΟΎ 0).

Non-enzymatic browning (NEB) due to the Maillard reaction (MR) was studied in a closed starch/glucose/lysine model system (20 g kg-1 glucose, 10 g kg-1 lysine) in order to analyse conditions favouring reactivity during an industrial process of pasta VHT (very high temperature) thermal treatment. The
