  • Title: [Role of lipoxygenase in the determination of wheat grain quality].
    Author: Permiakova MD, Trufanov VA, Pshenichnikova TA, Ermakova MF.

    Abstract:
    Analysis of the correlation between endogenous lipoxygenase activity and 15 wheat grain quality parameters in three bread wheat populations has shown that enzyme activity influences the weight of 1000 grains, dough deformation energy, dough tenacity, and mixing properties. The correlations between the enzyme activity and the basic quality parameters are negative at high activity levels. The optimum values of specific lipoxygenase activity at which all quality parameters studied have the maximum values range from 108.5 +/- 1.2 to 126.4 +/- 1.9. It has been found that the ability of lipoxygenase to strengthen gluten is related to the lowering of dough extensibility.
