Comparison of cadmium pathways in a high Cd accumulating cultivar versus a low Cd accumulating cultivar of Theobroma cacao L.

Understanding cadmium (Cd) pathways in cacao trees is critical for developing Cd mitigation strategies. This study investigates whether Cd uptake and translocation mechanisms differ between a low and a high Cd-accumulating cacao cultivar. We sampled three replicate trees of each cultivar, and a grafted cultivar that shared the same scion as the low Cd accumulator but had a different rootstock.

Acidic hydrothermal processing of wheat using citrate buffer largely enhances iron and zinc bioaccessibility and bioavailability to Caco-2 cells.

Phytate chelates iron (Fe) and zinc (Zn) in wheat. A multifactorial experiment showed that hydrothermal processing (45-60 °C, pH 4.0-6.

Using optimized monochromatic energy dispersive X-ray fluorescence to determine the cadmium concentration in cacao and soil samples.

Following the implementation of food safety limits on cadmium (Cd) in cacao products, there has been a growing demand for monitoring Cd in cacao tissues and soils. Traditional methods like acid digestion followed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) are time-consuming and costly. X-ray Fluorescence is an alternative technique that offers advantages in terms of speed, cost, ease of use and less environmental impact.
