Promotion of mineral quality of grain of tartary buckwheat

Knowledge of spatial distribution of elements and their binding forms within grains of cereals and pseudocereals is becoming increasingly important to optimize the processes of grinding of grains for the production of the highest quality grade. At the symposium we promoted with a poster the mineral quality tartary buckwheat grain, which is an important source of minerals especially for people with celiac disease, because grains do not contain gluten. At the tissue level spatial distribution of elements was studied using micro-PIXE, while at cellular level in the cotyledons LEXRF was used. We have shown that the majority of Mg, P, S, K, Mn, Fe, Cu and Zn accumulated in the cotyledons, while Ca was predominant in the husk. Within the cotyledons, the lateral distribution of P (in grains and seeds co-builds phytic acid) and Mg was correlated well, which suggested their binding. Correlation of P distribution and other elements studied was Cu) Fe) Mn) Zn. The results show that a significant proportion of Cu, Fe, Mn, Zn, especially in the cotyledons of tartary buckwheat also binds to other components (e.g. proteins). Poster was in competition of 38 posters second best and was as such much noticed and that objective of tartary buckwheat promotion was achieved.
