摘　　要：研究了木薯全粉对饼干储藏期品质和质构特性的影响,以不同比例木薯全粉替代低筋面粉制作饼干,对其理化和质构指标进行评价。结果表明:添加木薯全粉使得饼干的明亮度下降,色泽变黄。木薯全粉可降低储藏期饼干的水分含量和吸水率,提高脆性。其中,木薯全粉与低筋面粉比例为30/70时,饼干在储藏期内水分含量、咀嚼性和硬度最低,脆性最高。当木薯全粉与低筋面粉的比例大于40/60时,与对照组相比,饼干的硬度、弹性和咀嚼性升高,饼干的品质下降。The paper focused on the effect of the cassava flour on the qualities and texture characteristics of biscuits during storage,different proportion of cassava flour instead of low-gluten flour was made biscuits,and evaluated the physical and texture indexes of the products.The results showed that the brightness of biscuits add the cassava flour was decreased,colour and lustre was turned yellow.The cassava flour could reduce the moisture content and water absorption,improved the brittleness of biscuits during storage.Thereinto,the biscuits during storage had the lowest moisture content,chewiness,hardness,and the highest brittleness when the cassava flour and low-gluten flour ratio was 30/70.When the cassava flour and low-gluten flour ratio exceed 40/60,hardness,springiness and chewiness were raised,the quality of biscuits were declined compared with the control.
