野生食用蕈菌不同部位的红外光谱研究

测试了野生食用蕈菌子实体不同部位的傅里叶变换红外光谱。结果显示，同一蕈菌的菌盖皮、菌褶、菌盖肉、菌柄的红外光谱显示差异，红菇科红菇属的青头菌、大红菇的菌盖皮与其他部位的光谱有较大差异；鹅膏科鸡纵菌的菌褶与其它部位的光谱有明显区别。表明蘑菇同一子实体不同部位的化学组成有差异。通过蘑菇不同部位的红外光谱有可能区分不同种类的蘑菇。

Fourier Transform Infrared Spectroscopic Study of Different Parts of Wild Growing Edible Mushrooms

In this paper, vibrational spectra of different parts of fruiting bodies of wild growing mushrooms were recorded with Fourier transform infrared spectrometer. It was different for the spectra of cap skin, gill, cap meat and stem of the same mushroom. The great differences were found between cap skin and other parts of the same mushrooms of Russula virescens and Russula rubra, whereas the spectra of mushroom Termitomyces albuminosus show greated differences between gill and other parts. These indicate variety in the chemical composition of different parts of the same fruiting body. The results suggest that the mushrooms oould be identified at the species level by comparison of the vibrational spectra of different parts of fruiting bodies of mushrooms.
