摘要: 为了解决全麦馒头口感粗糙、质地干硬、食用品质差等问题,本文研究阿魏酸(Feuric Acid,FA)对全麦面团结构和热机械特性影响,并探讨了添加阿魏酸对全麦馒头质构特性和气孔分布影响规律。本研究将不同比例(0.5%、1%、1.5%)阿魏酸添加到全麦面粉制成面团,通过Mixolab混合试验仪测定阿魏酸对全麦面团中面筋蛋白弱化程度、淀粉糊化特性以及酶降解速率等特性,利用扫描电镜分析面团微观结构,最后,通过研究全麦馒头质构和气孔分布等指标来评估全麦馒头品质变化情况。结果表明,添加阿魏酸显著缩短了全麦面团的形成时间与稳定时间,其中,添加0.5%阿魏酸时,全麦面团的形成时间和稳定时间较对照组分别减少21.02%和42.41%,并促进了面筋蛋白连续、均匀网状结构的形成。同时,添加0.5%阿魏酸能够显著提升全麦面团的持水能力,有效减缓了贮藏期间全麦馒头芯中的水分损失。此外,与对照组相比,添加0.5%阿魏酸使全麦馒头比容提高了20.26%,显著改善了全麦馒头微观结构以及弹性、内聚性等质构特性。然而,高添加量阿魏酸(1%-1.5%)的添加会引起面筋网络结构断裂,对全麦面团流变特性和质构品质产生负面影响。该研究为解决传统全麦馒头口感粗糙、质地干硬等关键问题提出了新的解决方案,为提升全麦面团流变特性与全麦馒头质构品质提供理论依据。

Abstract: In order to solve the problems of rough taste, hard texture and poor eating quality of whole wheat steamed bread, the effect of ferulic acid (FA) on the structure and thermomechanical properties of whole wheat dough was studied. The effect of adding FA on the texture characteristics and pore distribution of whole wheat steamed bread was discussed. Different proportions (0.5%, 1%, 1.5%) of FA were added to whole wheat flour to make dough, and the weakening degree of gluten protein, starch gelatinization characteristics and enzyme degradation rate of FA in whole wheat dough were measured by Mixolab. The microstructure of the dough was observed by scanning electron microscope. The results showed that the formation time and stabilization time of whole wheat dough were significantly shortened 21.02% by the addition of FA, and the formation time and stabilization time of whole wheat dough were reduced 42.41%, compared with the control group. The formation of continuous and uniform network structure of gluten protein was promoted. The addition of 0.5% FA could significantly improve the water-holding capacity of whole wheat dough and effectively slow down the water loss in the core of whole wheat steamed bread during storage. In addition, compared with the control group, the addition of 0.5% FA increased the specific volume of whole-wheat steamed bread by 20.26%, and significantly improved the texture characteristics of whole-wheat steamed bread. However, the addition of high doses of FA (1%-1.5%) can cause structural rupture of gluten network, which negatively affects the rheological properties and texture quality of whole wheat dough. This study proposes a new solution to solve the key problems of traditional whole-wheat steamed bread, such as rough taste and hard texture, and provides a theoretical basis for improving the eating quality of whole-wheat steamed bread.
