“…The authors reported higher values of Fe, Cu, Mn, and Zn than those found in the present work. Comparing our results for the microelement contents in the analyzed tomato farmers' varieties with the information published in the scientific literature, Rosa-Martínez et al [39] reported similar values of Zn (0.08-0.18 mg/100 g) but a lower content of Fe (0.11-0.24 mg/100 g) and Cu (0.02-0.06 mg/100 g), whereas Hernández Suárez et al [30] found lower concentrations of Fe (0.18-0.22 mg/100 g), Cu (0.024-0.032 mg/100 g), and Zn (0.069-0.086 mg/100 g) but a higher amount of Mn (0.054-0.066 mg/100 g). Moreover, the results for Fe (0.129-0.302 mg/100 g) and Zn (0.162-0.336 mg/100 g) obtained by Bonemann et al [29] were in accordance with those reported in the present study.…”

“…Researchers have previously confirmed that mineral concentrations in tomato fruits are strongly influenced by the genotype [34,36]. However, regardless of the variety, K is the prevalent mineral found in tomatoes [34,[36][37][38][39]. Indeed, among the macroelements studied by Rouphael et al [40], K was by far the most abundant mineral constituent in two different greenhouse tomato cultivars, followed by Ca, P, Mg, and Na.…”

“…They reported mean values for K, Mg, and Ca of 285, 12.3, and 12.3 mg/100 g fw, respectively, and observed that the concentration of all analyzed minerals tended to be higher in the cocktail cultivars than the salad tomatoes. In another study, Rosa-Martínez et al [39] determined the mineral composition of ten varieties of tomato grown under the same environmental conditions using organic agricultural practices. The authors harvested the fruits at the red stage of maturity and reported values of K (68.36-117.6 mg/100 g) and Mg (4.00-9.55 mg/100 g) lower than those found in the present work.…”

Traditional farmers’ varieties of tomato grown under extensive farming techniques are considered delicious and healthy foods and are preferred by local consumers. Tomatoes are an important component of a healthy diet, as they provide essential micronutrients, including minerals, which are vital to healthy development, disease prevention, and wellbeing. Given the considerable dietary intake of tomatoes and the scarcity of information about the bioaccessibility of inorganic constituents in this fruit, this study was carried out to evaluate the content and bioaccessibility of minerals (macro- and microelements) in tomato farmers’ varieties widely cultivated in northeastern Portugal homegardens. Among the macroelements, K stood out as the most abundant mineral in the studied varieties, followed by Mg, Ca, and Na. Regarding the microelements, while the yellow tomato had higher concentrations of Fe and Cu, the round tomato had more Zn and Mn. The in vitro bioaccessibility assessment showed that, among the macroelements, Mg was more bioaccessible than Ca and K when all the tomato varieties were considered together. Among the microelements, Cu seemed to be the most bioaccessible. Although the contribution of a 100 g serving of the studied tomato farmers’ varieties to the dietary reference intakes (DRIs) of minerals is relatively low, this food could contribute to reaching these mineral requirements, as it is included in the diet of most of the population, especially in Mediterranean regions.

“…Apples have a relatively high content of organic acids [36] . For instance, apples’, beetroots’, and eggplants’ main organic acid is malic acid, but apples can present up to 30 mg/g of fresh weight (fw) of this compound (depending on the variety and ripening) [37] while eggplants and beetroots show about 1.3 and 3.6 mg/g fw, respectively [38] , [39] . Concerning the soluble solids content, the eggplant sample and its juice showed the lowest value and apples showed the highest.…”

“…Eggplant fruits have a high concentration of health-promoting bioactive compounds that provide adequate nutritional benefits to human health [1,2]. Eggplants are a popular food delicacy due to their high content of carbohydrates, protein, vitamins, and trace amounts of minerals like copper, zinc, and iron [3][4][5]. Eggplants are considered a valuable vegetable crop due to the presence of important phytochemical and nutraceutical compounds, particularly polyphenols and soluble fiber.…”

AMF and PSB applications modulated the biochemical and mineral content of the eggplants

This study was conducted to investigate the beneficial role of phosphate solubilizing bacteria (PSB) and arbuscular mycorrhizal fungi (AMF) in improving eggplant fruits' biochemical composition and mineral content.The plants were treated with AMF Acaulospora laevis, and bacteria Pseudomonas fluorescens, and the corresponding variations were measured for mineral content (Ca, Fe, Mg, K, and P), biochemical parameters (dry matter, total soluble solid [TSS], phenolics, chlorogenic acid, vitamin C) along with arbuscular mycorrhiza spore number, and percentage of root colonization. The AMF and PSB-mediated soil and root-associated nutrients become available for uptake via mineralization, solubilization, and mobilization, primarily through the generation of organic acids and P-hydrolysing enzymes by the microbes. All the treatments showed a significant increase in the concentrations of different biochemical components. However, the combination of both A. laevis and P. fluorescens was found to be the most efficient.These results indicated the possibility of A. laevis and P. fluorescens being used as biofertilizers.
