Microclimatic conditions and fruit maturity can affect the health-promoting compounds in tomato fruits. The aim of this study was to evaluate the influence of Mediterranean and continental weather conditions, on fruit firmness and coloration as well as on the concentrations of lycopene, alpha- and beta-carotene and lutein and on alpha-, delta- and gamma-tocopherol, in fruits of 10 processing tomato varieties. Compositional data analysis was carried out in order to determine the composition of carotenoids and tocopherols. Mediterranean weather conditions associated with agricultural practice have contributed to faster fruit ripening, which significantly improved the coloration with all varieties, and significantly increased the concentration of total carotenoids and lycopene with varieties with oval and elongated fruits. Environmental conditions in a low tunnel increased the red coloration, but did not significantly increase the content of either total carotenoids or tocopherols. The cultivar and the location of cultivation had a strong effect on the composition of the analyzed lipophilic antioxidants.
小气候条件和果实成熟度会影响番茄果实中的具有促进健康作用的化合物。本研究的目的是评估地中海和大陆性气候条件对 10 个加工番茄品种果实硬度和色泽以及番茄红素、α-和β-胡萝卜素、叶黄素和α-、δ-和γ-生育酚浓度的影响。为了确定类胡萝卜素和生育酚的组成,进行了成分数据分析。与农业实践相关的地中海气候条件促成了果实更快地成熟,这显著改善了所有品种的色泽,并显著增加了椭圆形和长形果实的总类胡萝卜素和番茄红素的浓度。在小拱棚中的环境条件增加了果实的红色着色,但对总类胡萝卜素或生育酚的含量没有显著影响。品种和种植地点对分析的脂溶性抗氧化剂的组成有很强的影响。
