Abstract:
Ten Croatian and five German wheat varieties were tested. Wheat protein composition was analysed according to a modified Osborne fractionation. They were extracted in four fractions: NaCl fraction, ethanol fraction, acetic acid fraction and insoluble fraction. The influence of protein and protein composition on the loaf volume was investigated. In protein composition a difference between the Croatian and German wheat varieties were found. Protein content, glutenin content and insoluble glutenin content showed influences on the loaf volume.
