中文摘要: 为研究适合麸质过敏人群食用的米面包，通过添加酶来改善米面包的品质，以碎米为原料制作米面包，探究添加单一酶制剂（α-淀粉酶、脂肪酶和谷氨酰胺转氨酶）和复合酶制剂（α-淀粉酶和脂肪酶复配）对米面团糊化特性和质构特性的影响，探究酶添加量、醒发时间、醒发温度和pH值对米面团糊化特性和综合评分的影响，通过单因素和响应面试验优化米面团最优制作工艺。结果表明，选取谷氨酰胺转氨酶对米面团进行改性，米面团最优制作工艺为谷氨酰胺转氨酶添加量0.008 g、醒发时间87 min、醒发温度63℃。此条件下制备的米面包感官评分从65.2提高到80.7、硬度从994.6 g降低到756.5 g、比容从1.97 mL/g增加到3.01 mL/g。
Abstract:This study aimed to develop suitable rice bread for people with gluten allergy and improve the quality of rice bread by adding enzymes.Rice bread was made with broken rice，and the effects of single enzyme preparations（α-amylase，lipase and transglutaminase）and compound enzyme preparation（α-amylase+lipase）on the pasting and texture properties of rice dough were investigated.The effects of enzyme dosage，fermentation time，fermentation temperature and pH on the pasting properties and comprehensive score of rice dough were investigated.The optimal fermentation conditions were optimized by response surface methodology on the basis of single factor tests.The optimal conditions for the fermentation of rice dough were as follows：transglutaminase dosage of 0.008 g and fermentation at 63℃for 87 min.The preparation of rice bread under the optimal conditions raised the sensory score from 65.2 to 80.7，decreased the hardness from 994.6 g to 756.5 g，and increased the specific volume from 1.97 mL/g to 3.01 mL/g.
