During our research, we added 0.5–2.0% L-lysine to wheat flour in order to increase the quantity of this essential amino acid and the biological value of the wheat protein, producing such a functional, health-protecting, and health-preserving foodstuff that is suitable for satisfying the lysine requirement of humans, assuming normal nutrition. Furthermore, by the increase of the biological value completing the wheat flour with a higher amount of lysine, we could produce such a functional, health-protecting and health-preserving food that is suitable for containing or preventing lysine malnutrition symptoms. During our work, we determined the quantity of the Maillard reaction products (hydroxymethyl-furfural) and the lysine content developed during the baking of the wheat flour used for bread baking and in the bread baked with supplemented or without supplemented lysine, and evaluated the sensory characteristics of the produced functional food and the bread supplemented with lysine.

After developing the decontamination method with UV light and establishing the specific analytical procedure with multiple extraction and HPLC, a method was developed to determine the effect of temperature on AFB1, AFB2, AFG2 and T-2 mycotoxins’ decomposition in sunflower oil. This paper presents an experimental study concerning the decontamination of mycotoxins in sunflower oil with a new type of photoreactor; the aim of this study was to determine the influence of temperature during the photochemical process. Experiments were conducted at different temperatures, observing the mycotoxin concentration decrease. Our study on the decontamination process shows the relevance of temperature effect; data confirm the differences between AFB1, AFB2, AFG2 and T-2 mycotoxin behaviour. In the photochemical conditions used, obtained mathematical models and specific data can be used to determine the conditions needed by the evolved refining process. Comparing the proposed decontamination process with the classic procedure, photochemical decontamination can be used to increase the nutrient value of the sunflower oil.

In Hungary a 5-year program was conducted to investigate the advantages of heterogenous population in forage maize production, to compare the cms analogues without restorer gene to normal versions, to learn whether the opaque-2 germ plasm has advantages as silage. The results in field of improving near infra-red (NIR) technique were reported too. The mixed population containing different maize genotypes is good to extend the harvest period, that is for increasing the utilization of harvesting and ensilaging capacity.Different sorts of sunflower, soybean; and sourghum were investigated as partners for inter-cropping based on maize. Regarding two requirements; planting at the same time with maize, and to obtain fermentable dry matter yield (30% DM content), - are met only by the sorghum. The headless sorghum is more suitable for this utilization than the normal one. If the complete seed set is occured, the cms analogue without restorer gene has advantage for both grain and forage use compared to the normal one. The degree of advantage depends on cms-sources, genotype, and environment. Regarding both the grain and stover yield, the sink limit hybrids seem to be more suitable for using out the advantages of cms. The opaque-2 germ plasm is as good as normal for forage use.Improving the earlier, NIR-calibration it is possible to measure in situ dry matter digestibility, cellulose content and digestibility, hemicellulose content and digestibility, lignin content, soluble carbohydrate and starch contents. Significant differences were found using NIR-technique among inbred lines, F4 segregated generation, hybrids, in treatments for N-fertilization and plant density.
