Correlation between the protein content and mechanical properties of wheat

The mechanical properties of wheat varieties are important in the milling industry. This study investigated the correlation between the protein content of 5 wheat varieties and their mechanical properties of rupture force, energy absorbed, and hardness. Based on correlation coefficients, a strong correlation was found between the protein content of all wheat varieties investigated and their mechanical properties. The correlation levels between the protein content and rupture force, energy absorbed, and hardness were r = 0.953, 0.883, and 0.884 for X-X load orientation and r = 0.955, 0.963, and 0.954 for Y-Y load orientation, respectively.
