The study of influence of masticatory properties on retronasal aroma

点击翻译按钮获取中文摘要

Influence of masticatory properties (masticatory force, masticatory frequency, masticatory duration, saliva volume, and breath flow volume) on generation of retronasal aroma was investigated. Values of masticatory properties depended on each panelist, and they showed wide range. Therefore, a mouth model which simulated mouth conditions in variable masticatory properties was constructed with monitoring system of masticatory force. Released aroma during mimic mastication was collected with the mouth model, and the amount of released aroma was analyzed with GC-MS and PTR-MS. Volume of retronasal aroma was influenced by breath flow volume and frequency very much.
