%X In order to investigate the pyrolysis behavior of the flavor precursor of geranyl-beta-D-glucopyranoside, the glycoside was pyrolyzed at 200, 300, 400 degrees C in an on-line pyrolyzer under anaerobic conditions and in an off-line mode separately. Gas chromatography-mass spectrometry (GC/MS) was used for the qualitative and quantitative analysis of the pyrolysis products. the results. Little geranyl-beta-D-glucopyranoside was pyrolyzed at 200 degrees C and there were a large amount of geraniol and little by-products produced at 300 degrees C. With the increasing temperature to 400 degrees C, both the pyrolytic products and by-products were significantly increased. Therefore, it indicated that the optimized temperature of pyrolysis was 300 degrees C. The main pyrolysis product of the glycoside was geraniol. It showed the primary decomposition reaction took place with the breaking of glycosidic linkage, the cleavage of O-glycosidic bond as expected. The on-line mode experiment was a rapid and good qualitative method for the pyrolysis, and the off-line mode can be used as a quantitative method based on the qualitative analysis.
