Curcumin dye in methanol solution was treated in $100^{circ}C$ oven (OV) and $H_2O_2/UV/O_2$(PER) conditions and thy degradation products were examined using gas chromatography mass spectrometry (GC-MS). Curcumin itself was not detected from either the OV or PER degraded samples. From OV degradation samples curcumene 1, o-coumaric acid 2, vanillin 3, 2,4-di-tert-butylphenol 4, benzene, 1-(3-cyclopentylpropyl)-2,4-dimethyl-4 5, 1-(4-hydroxy-benzylidene) acetone 6, feruloylmethane 7, and 2-propenoic acid, 3-[4-(acetyloxy)-3-methoxy phenyl]-, methyl ester 8 were detected. From PER degraded samples new products benzoic acid 9 and vanillic acid 10 were detected additionally. Under the same GC-MS instrumental condition, it is possible that the burial degraded curcumin dye or curcumin dyed textile will exhibit area peaks around $6.2{sim}6.5;min$ and $8.3{sim}8.4;min$ retention times, which have the mass spectrum matching closely with products 3, 4, 7, 8 or 9, 10.
