Component analysis of extracellular polysaccharide by Abortiporus biennis and its application in cigarette aroma
In order to develop new natural fungal perfume , the fermented extracellular polysaccharides (EPS) from Abortiporus biennis were purified by Sepharose CL-6B.The structure and monosaccharide composition of EPS were investigated by infrared spectroscopy (IR) and GC-MS analysis.After addition of EPS into tobacco conduction , the changes of flavoring substances in cigarettes were compared with control by simultaneous distillation and GC /MS.It was shown that EPS was monocomponent with the monosaccharide composition of 51.45% glucose, 30.30%mannose and 15.51%galactose.With application of EPS in tobacco production , the contents of ketones, aldehydes and furans increased in the cigarettes , while the contents of phenols and heterocyclic compounds decreased significantly.The treatments with EPS could reduce stimulation of smoking , and improve the aroma of cigarette to ameliorate the quality of smoking.
