    Abstract: 大麥(Hordeum vulgare L.)為重要的農作物,且富含高量的膳食纖維常用於機能性產品之開發。為此,本研究目的是建立富含膳食纖維之大麥擠壓膨發點心生產條件。研究中以 40%的大麥為主原料,並添加四種不同比例之糙米及玉米,在螺軸轉速(200 及300 rpm)、 模具溫度(110、120及130℃)及進料含水率15%條件下進行。結果顯示隨著玉米添加比例增加,L 值與徑向膨發率會提升, a 值和b 值則會增加;減少糙米添加比例吸水性指標 會下降;而水溶性指標成反比。在質地剖面分析減少糙米添加比例,硬度和最大剪切力會 降低。整體而言,以模具溫度130℃,螺軸轉速300 rpm 的條件作為產品開發具有較佳物理性質。
