摘    要:利用傅里叶变换红外光谱法(FTIR)研究了担子菌木耳目、非褶菌目和伞菌目6个科9个属的10种食用菌的子实体。将光谱分为5个区S1区(3050~2800cm^-1),S2区(1750~1500cm^-1),S3区(1500~1200cm^-1),S4区(1200~950cm^-1),S5区(950~700cm^-1);在5个区中,强峰出现在S4区的1080cm^-1附近和1040cm^-1(1020cm^-1)附近,以及S2区的1640cm^-1附近,1640cm^-1附近的峰为酰胺I振动峰,前两峰为糖类振动峰。根据5个区光谱峰值和吸收强度比,可以鉴别不同的食用菌。700~950cm^-1范围有可能作为区分不同属蘑菇间的指纹区。

关 键 词:食用菌  傅里叶变换红外光谱  鉴别  指纹图谱

Abstract:In this paper, Fourier transform infrared spectroscopy (FTIR) was used to identify edible mushrooms belonging to Auriculariales , Aphyllophorales, and Agaricales of Basidiomycotina. Vibrational spectra of fruiting bodies of ten species belonging to nine different genera of mushrooms (one is cultivated, and the others are wild growing) were recorded. The spectra were divided into five regions, i.e. 3 050 to 2 800 cm -1 , 1 750 to 1 500 cm -1 , 1 500 to 1 200 cm -1 , 1 200 to 950 cm -1 , and 950 to 700 cm -1 . These regions contain characteristic bands among different mushrooms. According to the characteristic bands in the five regions, different species of mushrooms can be identified. Vibrational spectra in the interval between 950 and 700 cm -1 could serve as fingerprints to discriminate different genera of mushrooms.
Keywords:Edible mushrooms  Fourier transform infrared spectroscopy  Identification
