T. Rakcejeva et al. Biological Value Changes in Grain During Biological Activation TimeFig. 1. Decrease in total protein content in grain during grain activation time.Fig. 2. Dynamics of dietary fibre content in grain during grain activation time.The amount of total sugar content increased1.3 times in hull-less barley grain, 1.2 times in ryegrain, and 2.0 times in wheat grain during the grainactivation time for up to 24 hours (Fig. 3) which canbe explained by the synthesis of carbohydrates in cellwalls of grain for grain sprout development.Changes in vitamin content in grain during theactivation time. The amount of vitamin B 1in theactivation process of wheat, rye and hull-less barleygrain considerably decreased (Fig. 4).The decrease in vitamin B 1content can be explainedby the possible metabolism and biochemical reactionsoccurring during the activation time and the availabilityof vitamin B 1in enzyme phyrovatdecarboxylasis whichparticipates in the growth and splitting reactions ofcarbohydrates occurring in grain (Казаков, Кретович,1989). During the activation for up to 24 hours, thecontent of vitamin B 1decreased by 32.10% in wheatgrain, by 57.78% in rye grain, and by 17.39% inhull-less barley grain.Contrary results were observed for the contentof vitamin B 2(Fig. 5). The amount of vitamin B 2increased by 45.5% in rye grain, by 54.5% in wheatgrain, and by 88.9% in hull-less barley grain duringthe activation time for up to 24 hours. The increaseof B 2content in hull-less barley and wheat grain wasvery similar. As inactivated rye grain is richer in thecontent of vitamin B 2compared to inactivated wheatand hull-less barley grain, the increase in vitamin B 2amount was more pronounced which can be explained28LLU Raksti 18 (313), 2007; 25-33
