The effect of water supply for yield formation of processing tomato
Published November 13, 2012
165-168

The effect of irrigation on tomato yield depends on the actual weather conditions, basically the air temperature and precipitation (quantity and dispersion). The irrigated plants gave a significantly higher yield, and rainfed plants showed a yield loss. The optimum water supply treatment gave a significantly higher proportion of lycopene than t...he control (rainfed) treatment (89% and 80% respectively) in case of Brixsol F1 variety. In spite of this we have not found significant difference in case of Strombolino F1 (cherry type). Content of total poly-phenols measured in Strombolino F1 (cherry type) was significantly higher than that found in the Brixol F1 (normal type). The optimum water supply treatment resulted in a significantly lower content of total polyphenols in both years. Tomato fruits are rich in polyphenols the largest amount of which is rutin from among the identified components.

Effect of using antioxidants as feed additives in the diet of dairy cows on the vitamin E and lycopene content of milk
Published December 1, 2010
69-72

In 2007, the aim of an Ányos Jedlik program and call for tenders was to support application-oriented, strategic research and development projects, which can increase the competitiveness of the Hungarian economy. In the framework of our project, we intended to examine whether non-protected antioxidants – in this case: vitamin E and lycopene ... used as feed-additives can increase the antioxidant content of milk. The milk with an
increased level of vitamin E and lycopene content can be used for producing functional foods which will represent competitive products on the current market of milk products. Our results show that the use of vitamin E as feed-additive can significantly increase the amount of vitamin E in the milk. The use of lycopene as feedadditive also gave good results. At the beginning of the experiment, the lycopene content of the milk was below the detection limit, while in the post-feeding milk samples the lycopene became detectable. Based on our results, we are of the opinion that further experiments and analyses are needed regarding the quality of food of animal origin and animal health.
