Abstract
Fruits are highly consumed worldwide and constitute a major nutritious food source. However, their food assessment has not been adequately studied and documented in certain areas based on their chemical analysis.Standard procedures were used to determine the proximate and chemical composition of fruits. Atomic absorption and flame spectrophotometer was used to determine the mineral composition,especially essential, trace, and toxic elemental contents like Na, K, Ca, Mg, Cr, Cu,Mn, Fe, Zn, As,Cd, and Pb in different fruits with rhizospheric soil and irrigation water collected from Larkana, Sindh, Pakistan. The content of moisture, ash, fiber, crude fat, crude protein, and carbohydrate recorded in the studied fruits were 85.24%, 2.84%, 5.23%, 2.14%, 3.30%, and 21.02%, respectively. The higher value of Na, Ca, Mg (6.8,17.2,21.66 mg/kg), and Cr (2.72 μg/kg) were found in jujube. In comparison, significantly higher values of Pb (3.95 μg/kg) and Cd (4.74 μg/kg) was observed in jujube and guava. The findings of this study suggest that the recommended daily allowance of important nutrients for the sustenance of healthy life and appropriate body functioning can be fulfilled through the fruits because there was no significant impact of heavy metals found. This clearly shows irrigation water and rhizospheric soil were found suitable for cultivation.
