Abstract
Bamano, King Creole, Sugarland, and DulceMiel hybrid tomato cultivars have been recently introduced in the Lazio area (Central Italy) to expand and valorize the regional/national market. Tomatoes from these cultivars, together with tomatoes from the native Fiaschetta cultivar, were sampled at the proper ripening time for the fresh market and characterized to obtain and compare their metabolite profiles. The Bligh–Dyer extraction protocol was carried out, and the resulting organic and hydroalcoholic fractions were analyzed by high-field Nuclear Magnetic Resonance (NMR) spectroscopy. NMR data relative to quantified metabolites (sugars, amino acids, organic acids, sterols, and fatty acids) allowed to point out similarities and differences among cultivars. DulceMiel hybrid and Fiaschetta native cultivars showed some common aspects having the highest levels of the most abundant amino acids as well as comparable amounts of organic acids, amino acids, stigmasterol, and linoleic and linolenic acids. However, DulceMiel turned out to have higher levels of glucose, fructose, and galactose with respect to Fiaschetta, reflecting the particular taste of the DulceMiel product. King Creole, Bamano, and Sugarland hybrid cultivars were generally characterized by the lowest content of amino acids and organic acids. King Creole showed the highest content of malic acid, whereas Bamano was characterized by the highest levels of glucose and fructose.
Highlights
Tomatoes (Lycopersicum esculentum) represent the most consumed vegetables worldwide grown for both fresh consumption and processing, identifying two different industry segments
Bamano and King Creole cultivars were characterized by a lower content of amino acids compared to the other samples
King Creole to 30.7% in DulceMiel, whereas tri-unsaturated fatty acid content (TUFA, linolenic acid) ranging from 24.7% in King Creole to 30.7% in DulceMiel, whereas tri-unsaturated fatty acid content was found to be nearly doubled in King Creole (15.96%) compared to Bamano (8.9%) which was (TUFA, linolenic acid) was found to be nearly doubled in King Creole (15.96%) compared to Bamano characterized by the lowest content
Summary
Tomatoes (Lycopersicum esculentum) represent the most consumed vegetables worldwide grown for both fresh consumption and processing (mainly to make tomato paste), identifying two different industry segments. According to statistics [1], 182 million tons of tomatoes were globally grown in. 2017, 25 million tons being produced in Europe. Forty percent of the European tomatoes are sold on the fresh market. Represents the first major European producer (followed by Spain), capable of providing 6 million tons of product per year. In the last two decades, breeding programs and hybrid seed production have been addressed to enhance plant tolerance to abiotic and biotic stresses, fruit nutritional value, and fruit quality [2].
