摘要: 烤麸是一种重要的健康食品,对其制作工艺进行优化有重要意义。以小麦谷朊粉为原料经过保温发酵后高温蒸制烤麸,研究发酵时间、原辅料配比及相关添加剂对烤麸品质的影响。以烤麸的感官评价为指标,通过单因素实验及正交实验,得出烤麸制作的最佳工艺及最适添加剂为:发酵时间3h,原辅料配比5:1,α-淀粉酶添加量为1U/g,分子蒸馏单甘脂为5g/kg,小苏打为3g/kg,干酵母为5g/kg,在此工艺条件下,制得烤麸的感官评分为97。本文研究成果将为烤麸制作工艺提供一定参考。Abstract: It was very important to study the processing of wheat gluten which was a kind of healthy food. Wheat gluten powder as raw material through the insulation after fermentation and high-temperature steaming baked bran, the quality of wheat gluten were estimated by the effect of fermentation time, ingredients and additives. By evaluation of sensory indicators, the single factor experiment and the orthogonal experiment showed the optimum processing of wheat gluten as following:fermentation period 3h, ratio of raw materials to secondary material 5:1, the addition quantity of α-amylase 1U/g, the addition of molecular distillation monoglyceride 5g/kg, baking soda 3g/kg, stem yeast 5g/kg, and this optimum condition make a good score of 97 for the sensory evaluation. This work would do some benefits for the processing of wheat gluten.
