摘要
主要研究了蜜柚膳食纤维蛋糕制作的配方工艺。以蛋糕成品的感官评价总分为依据,考察了植物油(A)、泡打粉(B)和膳食纤维(C)添加量三个单因素对蛋糕品质的影响。在此基础上,采用三因素三水平正交试验L9(34),对其配方进行优化。正交试验结果表明,当配方组合为A2B2C1即植物油、泡打粉及膳食纤维添加量分别为低筋粉含量的20%、%、3%时,蛋糕的综合感官评分最高。正交试验优化配方组合为A3B2C1,即植物油,泡打粉及膳食纤维添加量分别为低筋粉含量的25%、%、3%。结果显示,A3B2C1综合感官评分高于A2B2C1。最终确定蜜柚膳食纤维蛋糕制作配方为A3B2C1即植物油、泡打粉、膳食纤维最适添加量分别为低筋粉含量的25%、%、3%。此配方制得的蛋糕其水分、蛋白质和总糖含量均符合SB/T10030 92,菌落总数与大肠菌群符合GB7099-2003。

Abstract
This article mainly studied the production process about cake with dietary fiber from honey pomelo. Having investigated how the dosage of vegetable oil(A),baking powder (B)and dietary fiber (C) affect the quality of cakes according to the cake’s sensory-appraise scores. On this basis,using single-factor method and L9(34)orthogonal analysis method to optimize the recipe. The orthogonal test showed that the integrated sensory score reached highest when bination was A2B2C1,that’s the dosages of vegetable oil,baking powder and dietary fiber reached 20%,%,3% of the flour. However, pare the two binations, the integrated sensory score of A3B2C1 was higher than last it could be sure that the bination was A3B2C1, that was the dosages of vegetable oil,baking powder and dietary fiber reached 25%,%,3% of the flour. Cakes’ water ,protein and total sugar contents all conform to SB/T10030 92,and also the bacterium colony amount and the coliform group both conform to GB7099-2003 when it is made by the optimal recipe.

膳食纤维(Dietary )是指不被人体消化吸收的以多糖类为主体高分子物质总称,按其溶解性主要分为可溶性膳食纤维(soluble dietary fiber,SDF)和不可溶性膳食纤维(insol
