The influence of gamma radiation as well as microwave heating of wheat grain before sowing, on some changes in the true and apparent digestibility of albumins extracted from the first and second generation of wheat grains were studied. Gamma radiation doses 0,05 kGy and 0,1 kGy applied before sowing caused the statistically significant increase in the total protein content only in case of the first generation. Also in the first generation of wheat grains irradiated before sowing, the lower apparent and true digestibility were observed compared with control grain sample. Microwave heating applied before sowing through 15 sec. (28°C) to 180 sec. (98°C) caused some changes in total protein content only in case of the first generation of wheat grains. However albumins extracted from the first and second generation of wheat grain, bred from wheat kernels, which were treated by microwave heating, had statistically significant lower apparent and true digestibility in comparison to the control grain sample.
