For rye dough structure, it is hypothesised that the presence of arabinoxylan hinders the proteins from forming a coherent network. This hypothesis was investigated using fluorescent-stained antibodies that bind to the arabinoxylan chains. Image analysis proves that the arabinoxylan surrounds the proteins, negatively affecting protein networking. Further, it is hypothesised that the dosing of xylanase and transglutaminase has a positive impact on rye dough and bread characteristics; the findings in this study evidenced that this increases the protein network by up to 38% accompanied by a higher volume rise of 10.67%, compared to standard rye dough. These outcomes combine a product-oriented and physiochemical design of a recipe, targeting structural and functional relationships, and demonstrate a successful methodology for enhancing rye bread quality.
对于黑麦面团的结构,有人假设阿拉伯木聚糖的存在会阻碍蛋白质形成连贯的网络。本研究使用荧光染色的抗体来验证这一假说,这些抗体可以与阿拉伯木聚糖链结合。图像分析证明阿拉伯木聚糖围绕着蛋白质,对蛋白质网络的形成产生负面影响。此外,还有人假设木聚糖酶和转谷氨酰胺酶的添加剂量对黑麦面团和面包特性有积极影响;本研究的结果表明,与标准黑麦面团相比,这种方法可以将蛋白质网络增加多达 38%,同时体积增加 10.67%。这些结果结合了产品导向和配方的物理化学设计,针对结构和功能关系,展示了一种提高黑麦面包质量的成功方法。
