Determination of Macro- and Microelements in the Inflorescences of Banana Tree Using ICP OES: Evaluation of the Daily Recommendations of Intake for Humans

Abstract

The inflorescence of Musa paradisiaca, known as “banana heart” is a structure that includes flowers and bracts of banana, commonly used as food source worldwide. The aims of this study were (1) to determine the mineral components of Musa paradisiaca and (2) to compare the obtained results with previously reported data of Recommendation Dietary Allowances (RDAs) and edible plant permissible limits set by FAO/WHO. The samples were digested using microwave-assisted equipment, while elemental contents were determined by inductively coupled plasma optical emission spectroscopy (ICP OES). Metal (Mg, Ca, Cr, Ni, Cu, Fe, and Zn) and nonmetal (S and P) contents were detected. According to RDA, the inflorescences could be excellent sources of Mg, P, Cr, Cu, Zn, and Fe for females, males, and pregnant women, all age 31–50 y, as well as children (4–8 y). Bracts are good source of Zn for male and pregnant women and good source of Fe for children. All the samples contained considerable amounts of Mg, Ca, P, Ni, Cu, Zn, and Fe, which were quite low to induce deleterious effects (UL). FAO/WHO limits for edible plants have not yet been established for S, P, Mg, and Ca, but Ni and Zn are below of those limit values. However, Cr and Cu concentrations are higher than the values established for edible plants and may pose a threat to human health. Farmers should be encouraged by government agencies, not only for sustainability of production but also to ensure the storage and trade of banana tree inflorescence.

In Vitro Digestibility of Minerals and B Group Vitamins from Different Brewers’ Spent Grains

“…Ni also plays a key role in some enzymes, being an essential component [44]. Recently, Rosa et al [45] mentioned that the WHO and FAO established a permissible limit for the Ni content in edible vegetable sources of 1.63 mg/kg, but our results are below the limit (0.30-0.60 mg/kg). Sr is recommended in some countries as a supplement for enhancing bone mineral density [46], whilst Zn is an essential mineral for the development and growth of all organisms, playing a main role in different cellular functions such as cell growth and division, cellular transport, and immune and endocrine systems [47].…”

Effects of long-term banana cultivation on trace elements deposition in soil ecology

“…Microsoft Excel-2010 was also used for other calculation of the data. relatively substantial spatial variability in these constituents in the surface soil which might be due to the application of various agro-chemicals for banana cultivation (Dong et al, 2019;Rosa et al, 2020). There was a finding that trace elements extents in banana field were far higher than the virgin field (Fig.…”

“…Mean abundances of Cr (mg/kg) was perceived as 5.98 in leaves, 5.03 in stems, 2.30 in fruits and 8.54 in roots ( 2), suggesting the contamination of different tissues of banana plant by those elements and may impose risks to the consumers. The effects of applying garbage from disused areas, fertilizers, and pesticides to the banana fields may be to blame for the enhanced Zn, Mn, Cr, As, Pb and Cd concentrations in banana tissues (Ahmed et al 2016;Lin et al 2010;Rosa et al 2020). In declining instruction, the mean trace metal(loid) extents in various banana plant components were Fe > Zn > Mn > Cu > Ni > Cr > As > Pb > Cd.…”

Determination Of Macro Mineral Content In Fresh Noni Fruit (Morinda Citrifolia L.) By Atomic Absorption Spectrophotometry

“…Based on previous research, noni contains 31.15 mg/100g calcium, 19.65 mg/100g magnesium, 308.95 mg/100g potassium, and 201.5 mg/100g sodium. 5 Atomic absorption spectrophotometry, 6,7 inductively coupled plasma optical emission spectroscopy (ICP OES) 8,9 and flame atomic spectrometry, 10 were obtained to analyze macro and micro minerals in fruits and vegetables. The most widely used method for mineral analysis is atomic absorption spectrophotometry, 11 because its implementation is relatively simple and has high sensitivity (detection limit is less than 1 ppm).…”
