Ginger is an herbaceous perennial native to south-eastern
Asia, which thrives in mild climates. Due to its medicinal and health-promoting
properties and high nutritional value, ginger has attracted growing interest
among both dieticians and consumers. The aim of this study was to assess the
composition of mineral elements in various ginger root samples. The study
assessed the concentrations of the mineral elements Ca, Cu, Fe, Se, Mg, Zn, Na,
P, K, and Mn in samples of ginger roots collected from Kilimanjaro, Morogoro,
Iringa, Mbeya and Kagera regions. The collected ginger root samples were
cleaned, oven dried, grinded to fine powder and diluted in concentrated acids.
The solution samples obtained were analysed for the mineral elements by using
an Atomic Absorption Spectroscopy (AAS) method. The mean concentrations of the
analyzed elements were calculated and it was found that the ginger samples had
higher composition of Calcium (Ca), Magnesium (Mg), Sodium (Na), Iron (Fe), and
Potassium (K) followed by Manganese (Mn) then Zinc (Zn) and Copper (Cu) and
lastly no amount of Selenium (Se) was detected since its mean concentrations
were below the detection limit (0.50) mg/kg for the spectrometer used in this
study. The statistical techniques such as mean, standard deviation, and ANOVA
were employed to evaluate the data. Geographical relevance emphasises the
importance of choosing ginger samples from five different Tanzanian locations
and the data show how to comprehend with regional variations in minerals. The
findings' nutritional or agricultural ramifications, particularly the high
levels of calcium, magnesium, and iron and the lack of selenium, are given for
healthy interventions.
