中文摘要:

      目的 优化杜仲叶超微粉馒头制备工艺, 并对其品质特性进行分析。方法 以馒头感官评分及质构特性为考量指标, 以杜仲叶超微粉添加量、酵母粉添加量、水添加量为影响因素进行单因素试验; 在此基础上, 采用响应面试验优化杜仲叶超微粉馒头的制备工艺。结果 最优工艺条件: 杜仲叶超微粉添加量1.3%、酵母粉添加量1.6%、水添加量49%。按此工艺制备得到的杜仲叶超微粉馒头的感官评分为95.33±0.83分。各因素对杜仲叶超微粉馒头品质的影响顺序为: 杜仲叶超微粉添加量>酵母粉添加量>水添加量。馒头的质构特性表明: 添加杜仲叶超微粉后馒头硬度、胶黏性、咀嚼性及黏度均显著优于对照组(P<0.05)。结论 优化后杜仲叶超微粉馒头营养丰富, 且具有杜仲叶独特的风味, 有较大的应用潜力。

英文摘要:

      Objective To optimize the preparation technology of Eucommia ulmoides leaves superfine powder steamed bread, and analyze its quality characteristics. Methods The sensory score and texture characteristics of steamed bread were considered as the index, and the single factor experiment was conducted with the addition of Eucommia ulmoides leaves superfine powder, yeast powder and water as the influencing factors; on this basis, the preparation technology of steamed bread with Eucommia ulmoides leaves superfine powder was optimized by response surface methodology. Results The optimal conditions were as follows: 1.3% Eucommia ulmoides leaves superfine powder, 1.6% yeast powder, 49% water. The sensory score of the steamed bread with Eucommia ulmoides leaves superfine powder prepared by this process was 95.33±0.83. The effect of each factor on the quality of steamed bread with Eucommia ulmoides leaves superfine powder was in the order of Eucommia ulmoides leaves superfine powder addition>yeast powder addition>water addition. The texture characteristics of steamed bread showed that the hardness, gumminess, chewiness and viscosity of steamed bread with the addition of Eucommia ulmoides leaves superfine powder were significantly better than those in the control group (P<0.05). Conclusion The optimized Eucommia ulmoides leaves superfine powder steamed bread is rich in nutrition and has the unique flavor of Eucommia ulmoides leaves, which has great application potential.
