| Abstract: | Water-soluble browning polymers prepared from a L-alanine and D-glucose system at 95℃ for 4,6,12,18,24 and 30h,were experimented on to determine elementary composition,molecular weight distribution and infrared spectra.It was observed that the yield,molecular weight and the carbon content of water-soluble melanoidins depended on the reaction periods,and the number-avarage molecular weight (Mn) was up to >60000 at 30h.The infrared absorptions were gradually reduced as the reaction time became longer.Meanwhile the cigarettes with the water-soluble melanoidins added were found to be better than those with the control by panel. |
