Abstract

Abstract: It has been observed that em of phenylalanine and glycosylated phenylalanine in fluoresce spectra are 281.0 nm and 440 nm, respectively, that permits to investigate the suppression of Ge-132 on the Maillard reaction of phenylalanine without any interference. The result shows that the fluorescence intensity(FI) of glycosylated phenylalanine increases continuously with the decrease of FI of phenylalanine, and Ge-132 exhibits a suppression on the Maillard reaction of phenylalanine up to 42.3%.

Key words: Ge-132, phenyl alanine, Maillard reaction, fluorescence spectrum
