Abstract

Salt stress has been found to enhance the quality of certain plants, yet its influence on fruit flavor remains largely unexplored. Our study probes the impact of salinity on the nutritional and flavor profile of tomatoes. Tomato plants were exposed to 0, 30, 50, 70, 90, and 110 mM of NaCl. Moderate salinity levels (50–70 mM) were found to boost the nutritional value of tomatoes, with increases in soluble solids, protein, and sugar levels. However, the concentration of key minerals such as K, Mg, and Mn declined with escalating salinity. Furthermore, the number of volatile compounds has increased, and the content of different types (alcohols, aldehydes, esters, etc.) has also significantly increased. Salinity stress also significantly influenced the levels of characteristic volatile compounds, especially hexanal, phenylethyl alcohol, and 6-methyl-5-hepten-2-one. Overall, these results will provide valuable strategies for producing high-quality tomatoes.

期刊介绍： Food Chemistry: X, one of three Open Access companion journals to Food Chemistry, follows the same aims, scope, and peer-review process. It focuses on papers advancing food and biochemistry or analytical methods, prioritizing research novelty. Manuscript evaluation considers novelty, scientific rigor, field advancement, and reader interest. Excluded are studies on food molecular sciences or disease cure/prevention. Topics include food component chemistry, bioactives, processing effects, additives, contaminants, and analytical methods. The journal welcome Analytical Papers addressing food microbiology, sensory aspects, and more, emphasizing new methods with robust validation and applicability to diverse foods or regions.
