Abstract: The fluorescences of BSAand glycosylated BSAwere observed respectively. The λem of BSAwas 340 nm; while the λem of glycosylated BSAwas 436 nm. Because the fluorescence spectra of them were different greatly, we can observe the suppression of Ge-132 on the Maillard reaction of BSAwithout any interference of itself. It was showed that the fluorescence intensity of glycosylated BSAincreased continuously with the cultured time, Ge-132 may suppress the Maillard reaction of BSAgreatly, and the suppressing efficicency would be 32%. The key site of the Maillard reaction of BSAis free amino groups of alanine residues on Nterminal amino group, besides the ε- amino groups of intrachain Lysine residues.

Key words: Ge132, Bovine serum albumin(BSA), Alanine, Maillard reaction, Fluorescence spectrum
