摘要

为了减弱直接添加麦麸对面制品的不利影响,研究利用布氏乳杆菌-米曲霉按照2∶3的复配比例协同发酵处理麦麸,将发酵前后的麦麸分别按添加量3%、6%、9%、12%、15%(质量分数)添加至小麦粉中制成混合粉,探究发酵前后不同添加量的麦麸对面团特性的影响。结果表明,与直接添加麦麸相比,当发酵麦麸的添加量低于6%时能够显著改善混合粉的粉质特性和糊化特性,湿面筋含量、二硫键含量均显著提高。同时,发酵麦麸能够弱化麦麸添加对面筋蛋白的破坏作用,α-螺旋和β-折叠含量变化较小,在一定程度上减少了蛋白质稳定构象向其他结构的转变,减弱了添加麦麸对面筋蛋白的负面影响。当麦麸添加量高于6%时,混合粉的粉质特性、糊化特性与面筋含量均显著降低,不利于面团稳定结构的形成,影响麦麸面制品的营养品质,因此可将麦麸添加量控制在6%以下。研究结果可为全麦制品中麦麸添加质量分数的确定提供理论依据。

Abstract

To reduce the adverse effects of the direct addition of wheat bran on flour products, the collaborative fermentation of the wheat bran with Lactobacillus brucei and Aspergillus oryzae in the ratio of 2∶3 was studied.The wheat bran before and after fermentation was added to wheat flour at the ratios of 3%, 6%, 9%, 12%, and 15% to make different types of mixed powder, and the influence of different wheat bran addition before and after fermentation on dough characteristics was explored.Results showed that compared with the direct addition of wheat bran, when the addition of fermented wheat bran was less than 6%, the farinograph and gelatinization characteristics of the mixed flour were significantly improved, and the contents of wet gluten and disulfide bond were significantly increased.At the same time, the α-helix and β-fold contents changed little, which reduced the transformation of protein-stable conformation to other structures to a certain extent and weakened the negative effect of wheat bran addition on gluten.When the added amount of wheat bran was higher than 6%, the farinograph properties, gelatinization properties, and gluten content of the mixed flour were significantly reduced, which was not conducive to the formation of stable dough structure and affected the nutritional quality of wheat bran flour products, so the added amount of wheat bran should be controlled below 6%.The results provide a theoretical basis for determining the additive amount of wheat bran in whole wheat products.
