Cím:	Determination of the chromium content of Hungarian winter wheat / Zoltán Győri, József Prokisch
Dátum:	1999
ISSN:	0021-8561 1520-5118
Megjegyzések:	Bread and different winter wheat (Triticum aestivum) products are the main sources of chromium in the human diet in Hungary. Graphite furnace atomic absorption spectrometry (GF-AAS) is able to give reliable results for Cr. In this study the chromium content of some winter wheat species was determined after wet digestion. Contamination was the most critical part of chromium measurement; thus, appropriate sample preparation and the cleaning of kernels before digestion were required. The chromium content was 2-3 times higher than expected when contamination occurred. Samples came from a field plot experiment and, therefore, the effect of fertilization (150 kg/ha N, 112.5 kg/ha P2O5, and 132.5 kg/ha K2O) on chromium content of grains was studied. The average measured values of different species were 114 ( 3 and 134 ( 4 ?g/kg for the control and fertilized plots, respectively.

Cím:	Legumes Grown under Nonirrigated Conditions / Zoltán Gyõri, Eszter Nemeskéri, Szilárd Szilágyi
Dátum:	1998
ISSN:	0021-8561
Megjegyzések:	The nutritive quality of different ripening soybeans was compared with that of dry beans and various colored seeds and dry peas with regard to their protein and fat contents, amino acid compositions, and trypsin inhibitor activity. The bean protein of three legumes contained the highest levels of methionine, leucine, phenylalanine, and histidine, of the essential amino acids, respectively. The nutritive quality of soy protein, containing high glutamine contents, and dry pea protein, with its large valine contents, exceeded that of the others. Under nonirrigated growing conditions, there were high levels of leucine, valine, glycine, and proline in beans, independent of seed color. The beans with colored seed contained larger concentrations of methionine, cysteine, phenylalanine, and leucine essential amino acids than white bean. The lysine content of white bean protein was as high as that of the pea. The nutritive quality of white bean seeds could be increased with selection for low level of trypsin inhibitors under nonirrigated growing conditions. In water-deficient conditions, the level of valine and proline amino acids increased in soy seed protein, independent of the maturity groups. Irrigation has no effect on the increase, either in protein content or in essential amino acids, in soybeans and, indeed, there were no differences in the above-mentioned among the maturity groups.
