Ambient temperature vacuum distillation in conjunction with headspace- solid phase micro-extraction (HS-SPME) was used to study the volatile compounds (VC) in Agaricus bisporus. Different extraction times 2 3 4 and 5 h were also tested against VC yield and 4 h was found to be the best extraction time with most of the compounds retrieved. No significant difference was found between the VC extracted in 4 and 5 h. The samples were analysed as fresh boiled under reflux dried and dried and then boiled under reflux. The major peaks identified in all treatments were 4-methyl 3-penten-2one benzaldehyde 1-octen-3-ol 3-octanone 3-octanol and 2-octen-1-ol 1-octanol. Benzyl alcohol and 1-octen-3-one were identified whenever heat was applied while pyrazine limonene benzyl isothiocyanate and 4 phenyl-2-butenal were detected in dried then boiled under reflux samples. Thermal processing affected the relative concentration of VC where a decrease in the relative concentration of the main C8 compounds was observed while other compounds such as furfural limonene benzyl alcohol 3 5 5-trimethyl- cyclohexen-2-one were formed.

Abstract

Ambient temperature vacuum distillation in conjunction with headspace- solid phase micro-extraction (HS-SPME) was used to study the volatile compounds (VC) in Agaricus bisporus. Different extraction times 2 3 4 and 5 h were also tested against VC yield and 4 h was found to be the best extraction time with most of the compounds retrieved. No significant difference was found between the VC extracted in 4 and 5 h. The samples were analysed as fresh boiled under reflux dried and dried and then boiled under reflux. The major peaks identified in all treatments were 4-methyl 3-penten-2one benzaldehyde 1-octen-3-ol 3-octanone 3-octanol and 2-octen-1-ol 1-octanol. Benzyl alcohol and 1-octen-3-one were identified whenever heat was applied while pyrazine limonene benzyl isothiocyanate and 4 phenyl-2-butenal were detected in dried then boiled under reflux samples. Thermal processing affected the relative concentration of VC where a decrease in the relative concentration of the main C8 compounds was observed while other compounds such as furfural limonene benzyl alcohol 3 5 5-trimethyl- cyclohexen-2-one were formed.
