招募50 名食品专业在校学生,筛选、培训10 人组成感官评定小组,10 名感官评定员在自由咀嚼状态下咀嚼干腌肉样品并在不同咀嚼阶段收集食团及唾液。通过测定咀嚼过程中食团的水分含量、pH值、NaCl含量和唾液pH值、电导率以及使用电子舌检测分析其味觉特征,研究口腔加工过程中传统干腌肉的咸味释放规律。结果表明:咀嚼过程中食团的水分含量显著增加,NaCl含量持续降低,pH值无显著变化;从咀嚼开始到咀嚼终点唾液分泌量显著上升,唾液电导率持续升高;由电子舌检测分析可知,干腌肉咀嚼过程中,咸味的释放规律为先上升后下降趋势,且在30%咀嚼阶段咸味释放达到最高值。

A group of 50 food program students at Hunan Agricultural University were recruited and screened in order to create a 10-member sensory panel.The panel was asked to chew dry-cured meat samples in free chewing.At different chewing stages,bolus samples were collected to measure their moisture content,pH value and sodium chloride content,and saliva samples were also collected to determine their pH value and conductivity.Besides,an electronic tongue was used to dynamically trace the taste characteristics of dry-cured meat during chewing.Our aim was to investigate the pattern of change in salty tas...
