摘要: 面团的流变学特性会对面制品的质量产生重要影响,而食品添加剂的种类和添加量将显著改变面团的流变学特性。本研究利用质构仪考察了若干种食品添加剂对面团拉伸特性的影响。结果表明:面团中添加NaCl、单甘酯、明胶、抗坏血酸、面粉强筋剂、海藻糖等都对面团的拉伸性能有一定的影响,不同的添加剂影响各异。相对而言,1.5%~2%的NaCl、0.5%的单甘酯、0.4%的明胶、0.4%的面粉强筋剂等都对面团的抗拉伸性能和稳定性有明显改善。而总体上,抗坏血酸和海藻糖对面团拉伸性能的作用主要是增加其抗拉伸应力,但会使面团的拉伸时间显著缩短,本研究的结果为面制品生产中正确选择适当的食品添加剂及添加量提供了基础数据。

Abstract:  The quality of wheat dough product, such as bread, noodle and cake, was significantly influenced by the dough’s rheological properties. And food additives may have an effect on the dough’s rheological properties. In this paper, the influences of food additive on the stability of dough were studied by EZ-TEST Texture Analyzer. According to the rheological result, all food additive used in this research can affect the dough’s extensibility relatively. When the following food additives were used, namely NaCl (1.5%~2%), glycerol monostearate(DMG)(0.5%), gelatin (0.4%), and flour improver (0. 4%), the dough’s extensibility and the stability can be greatly enhanced. While the adding of L-ascorbic acid and trehalose enhanced the dough’s tensile strength, the extensional time was obviously shortened. These results are useful for us to choose the right food additives in the production of wheat dough food.
