The high molecular weight polymeric fraction of gluten, glutenin macro-polymer (GMP) shows strong relation with breadmaking quality of wheat. In this study, GMP was extracted from different Iranian wheat cultivars with different breadmaking performances. The correlation was investigated between the wet weight and (small-strain deformation) rheological characteristic of GMP-gel with bread quality (loaf volume and height). The results showed a significant relation between gel amount and bread loaf volume and height. However, no positive and significant correlation was found between small-strain deformation rheological characteristics (storage modulus and tan delta) with breadmaking characteristics. Concluding, despite to GMP wet weight which is accepted as a predictive measure for breadmaking quality, small-strain deformation rheological analysis of GMP-gel can not be used for screening breadmaking quality between wheat cultivars.
