摘要：以粳米粉替代传统戚风蛋糕中的低筋面粉制作米粉戚风蛋糕。确定了粳米粉戚风蛋糕的最佳配方为（焙烤%）：粳米粉100%、鸡蛋269%、蔗糖88%、水33%、油35%、塔塔粉2%。最佳操作工艺参数为：蛋白打发程度为干性发泡，面糊加入量为模具体积的60%，烘烤温度上火185℃、下火175℃、时间22min。对粳米粉戚风蛋糕进行室温五天保藏实验，以低筋粉戚风蛋糕为对照。粳米粉蛋糕的水分含量略有下降，由36.8%降至35.6%，下降幅度低于低筋粉蛋糕。粳米粉蛋糕的酸价高于低筋粉蛋糕，保藏期间酸价有较明显的升高，由2.09升至4.17。粳米粉蛋糕的硬度明显低于低筋粉蛋糕，保藏期间硬度由305.879g上升至583.645g，升高幅度略低于低筋粉蛋糕。相对而言，低筋粉戚风蛋糕的老化较为严重，体积回缩较大。41087

Studies on the Production of Rice Chiffon Cake and its Shelf Life
Abstract: In this paper, with japonica rice powder to replace low gluten flour of the traditional chiffon cake to make rice flour chiffon cake. The optimum formulation of rice powder Chiffon cake is ( for bake%)：rice flour100%, eggs269%, sucrose88%, water33%, oil35%, cream of tartar 2%. The optimum operating parameters is: crack egg white to stiff peck, add batter to an amount of 60% volume of the mold. Baking temperature: top heat 185 ℃ and bottom fire 175 ℃ for 22min.Preserve the rice powder chiffon cake for five days at room temperature, comparing with low-gluten powder chiffon cake. The moisture content of rice powder cake decreases slightly, from 36.8% to 35.6%, lower than the low-gluten powder cake. The acid value of rice powder cake is higher than the low-gluten powder cake. During the preservation, acid value has been significantly increased, rising from 2.09 to 4.17. The hardness of rice power cake is significantly lower than the low-gluten powder cake. During the preservation, the hardness increased from 305.879g to 583.645g, slightly lower than the low-gluten flour cake. Relatively, low-gluten powder chiffon cake is more seriously aging with a large volume of retraction.
