Abstract:

Wheat flour is one of the important raw materials in food processing, and its processed steamed bread is the staple food for people in the north. In order to analyze the relationship between the rheological fermentation characteristics of wheat dough and the processing quality of steamed bread, this study used 30 different gluten wheat varieties, such as ‘Shiyou 17’, ‘Shiyou 20’ and ‘Shimai 19’, as materials, and analyzed them using correlation and path analysis methods. The results showed that the hardness, gumminess and chewiness of TPA of steamed bread had extremely significant negative correlation with dough maximum expansion height (Hm), dough height at the end of the trial (h) and the time when dough began to leak carbon dioxide gas (Tx). The adhesiveness of steamed bread was extreme significantly positively correlated with the ratio of retained volume to total volume of released gas (Vr/Vt), extreme significantly negatively correlated with the time to reach the curve peak (T1), Vt and Vr, and had positive correlation with (Hm-H)/Hm. The adhesiveness, springiness, cohesiveness, and resilience of steamed bread demonstrated a highly significant positive correlation with Vr/Vt and a highly significant negative correlation with Vt. The parameters that had a positive effect on the steamed bread sensory score from large to small were: P value (maximum pressure P value), Ie value (elasticity index), weakening degree, flour quality index, T1 and Vr, and the parameters that had a negative effect were W value (deformation energy) and ratio of P/L (curve shape ratio).
