Abstract

Tea, second only to water in consumption, is rich in nutrients. Selenium, a crucial trace element, has unclear relationships with other substances in tea leaves. This study analyzed five white teas, measuring selenium, five minerals, and various chemical components. The results showed that there were significant differences in the elemental and chemical characteristics among these tea. Correlation analysis showed that low-level selenium might have a synergistic effect with iron, magnesium and potassium, while the correlations between other elements in tea leaves, total proteins, and total amino acids with selenium were not significant. In addition, the contents of flavonoids and polyphenols were significantly negatively correlated with the selenium content. These results indicated that selenium has a significant impact on the accumulation of minerals, flavonoids, and polyphenols in tea leaves. This study disclosed white tea's elemental and chemical basis, supplying a theoretical basis for quality evaluation, crucial for the tea industry.

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.
