Studies on Browning Reaction Products in No-oxygen Closed Systems

The Browning reaction products (BRPs)derived from L-alanine and D-glucose were prepared under different reaction conditions (pH, reaction time and solvents)in no-oxygen closed system and in open system. The effects of reaction conditions on the properties (color intensity, amino acid residue and organoleptic evaluation of the treated cigarettes)were investigated.The ethersoluble compounds of the BRPs from different solvent systems were further analyzed by GC and GC-MS.
