| Otázka kvality bio-produktu se stala vysoce aktuálním tématem. Konzumace biopotravin či produktů systémů s nízkými vstupy syntetických agrochemikálií („low input“) je stále více vnímána jako součást zdravého životního stylu. Obecně lze v takto pěstovaných plodinách očekávat nižší obsah látek pocházejících z chemizace zemědělství, jako jsou rezidua pesticidů, těžké kovy a dusičnany. Předností biopotravin muže být mimo jiné také zvýšený obsah některých živin. Je nutné však konstatovat, že zdravotní riziko z ekologicky pěstovaných potravin není automaticky nulové, za určitých okolností mohou totiž vykazovat zvýšený obsah přírodních toxických látek (napr. glykoalkaloidu), předmětem intenzivních diskusí je i možný vyšší obsah toxických sekundárních metabolitu... |

| The aim of this study was to investigate the effect of way of tomatoes cultivation on content of both health promoting and toxic components representing by carotenoids (lycopene, β-carotene), vitamin C and glycoalkaloids (α-tomatine, dehydrotomatine). The levels of biologically active compounds were shown to be strongly affected by the degree of maturity of fruit and varied among system with various fertilizers. Slurry, organic fertilizer with high fertilization efficiency, is good alternative to mineral fertilization. Lower content of toxic glycoalkaloids was found in tomatoes from organic and combined “low input” farming. The differences were variety depended in some extent. |

| Increasing public concern about environment and human health reflects in growing consumers´ interest in organic food. In order to have a free and informed choice between organic and conventional foods, an objective assessment of a product quality based on a sound scientific knowledge is needed. The aim of this project was an investigation of the influence of growing conditions on the potato (Solanum tuberosum) quality. Two traditional varieties (Katka and Finka) were grown at two different localities in Czech Republic. To determine a possible inter-annual variability, the experiments were performed on crops over a period of three consecutive years (2008 – 2010). The monitored parameters included biologically active compounds (chlorogenic acid, reducing... |

| The aim of this study was to investigate the influence of growing conditions on the quality of potatoes from organic farming systems as compared to that from conventional farming. In our previous study conducted in the years 1996 – 1999 we recognised some differences between the potatoes (Solanum tuberosum) from organic and conventional farming. To demonstrate the general validity of observed trends, follow up study was established in Czech Republic in the years 2002-2005. The ultimate goal of the project was to collate data for the assessment of a potential influence of foods from organic production system on consumers´ health by studying differences between potatoes grown in both systems (for this purpose the levels of potentially toxic compounds as... |
