Abstract:
Abstract: The current study aims to assess the infusion pattern of three important micronutrients namely copper (Cu), iron (Fe) and zinc (Zn) contents from black tea samples produced in Assam (India) and Thohoyandou (South Africa). Average daily intakes and hazardous quotient were reported for these micronutrients. Total content for Cu, Fe and Zn varied from 2.25 to 48.82 mg kg-1, 14.75 to 148.18 mg kg-1 and 28.48 to 106.68 mg kg-1 respectively. The average contents of each of the three micronutrients were higher in tea leaves samples collected from South Africa than those from India while the contents s in tea infusions in Indian samples were higher than in South African tea samples. Results of this study revealed that the consumption of not more than 600 mL tea infusion produced from 24 g of made tea per day may be beneficial to human in terms of these micronutrients content. Application of nonparametric tests revealed that most of the data sets do not satisfy the normality assumptions. Hence, Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation the use of both parametric and nonparametric statistical analysis that subsequently revealed significant differences in elemental contents among Indian and South African tea.
