This investigation examined how the laccase (rBVL-MRL522) influenced the physicochemical characteristics, structural attributes, and functional capabilities of both dough and noodles. Incorporating rBVL-MRL522 (1 U/g) did not lead to a substantial change in the water absorption of wheat flour. However, the introduction of rBVL-MRL522 caused a significant elongation in the formation time of wheat flour dough, extending it by 88.9%, and also resulted in a 50% increase in the stabilization duration of wheat flour dough. Furthermore, adding rBVL-MRL522 led to a proportional rise in both the elastic and viscous moduli (G'' of the dough, signifying that r-BVL (rBVL-MRL522) has a beneficial effect on the gluten strength of the dough. Integrating rBVL-MRL522 promoted the consolidation of the gluten-based cross-linked structure within the dough, decreasing the size of starch particles and, more evenly, the dispersion of these starch particles. In the noodle processing, adding rBVL-MRL522 at a rate of 1 U/g raised the L* value of the noodles by 2.34 units compared to the noodles prepared without the inclusion of rBVL-MRL522. Using a greater amount of rBVL-MRL522 (2 U/g) substantially increased the hardness of the noodles by 51.31%. Additionally, rBVL-MRL522 showed a noteworthy enhancement in the elasticity, cohesiveness, and chewiness of the noodles. In conclusion, rBVL-MRL522 promoted the cross-linking gluten, leading to a more extensive and condensed three-dimensional network structure in raw and cooked noodles. As a result, this study offers valuable insights into the environmentally friendly processing of dough and associated products.
本研究考察了漆酶(rBVL-MRL522)如何影响面团和面条的物理化学特性、结构属性及功能特性。添加rBVL-MRL522(1 U/g)并未导致小麦粉吸水率发生显著变化。然而,rBVL-MRL522的引入使小麦粉面团的形成时间显著延长,延长了88.9%,同时也使小麦粉面团的稳定时间增加了50%。此外,添加rBVL-MRL522使面团的弹性模量和粘性模量(面团的G'')成比例增加,这表明r-BVL(rBVL-MRL522)对面团的面筋强度有有益影响。整合rBVL-MRL522促进了面团中基于面筋的交联结构的巩固,减小了淀粉颗粒的尺寸,并使这些淀粉颗粒的分散更加均匀。在面条加工中,与未添加rBVL-MRL522制备的面条相比,以1 U/g的比例添加rBVL-MRL522使面条的L*值提高了2.34个单位。使用更多量的rBVL-MRL522(2 U/g)使面条的硬度大幅增加了51.31%。此外,rBVL-MRL522使面条的弹性、内聚性和咀嚼性有显著增强。总之,rBVL-MRL522促进了面筋交联,导致生面条和熟面条中形成更广泛、更致密的三维网络结构。因此,本研究为面团及相关产品的环保加工提供了有价值的见解。
