Elementary analysis in banana samples using X-Ray Fluorescence

Abstract

This work aims to characterize the elemental concentrations of two banana types gold and silver. In both were analyze in the pulp and peel by X-Ray Fluorescence technique. The results showed that the elements in both types are more concentrated in the peel than in the pulp. In addition, it was also observed that the normalization of the peel and pulp concentrations for the elements K, Fe, Zn, Br, Rb, and Sr is higher in the silver banana compared to the gold banana. The results indicate that banana peels can be used to supplement nutritional deficiencies. The work also demonstrates the potential that X-Ray Fluorescence has in investigation of elemental composition of foods. As the technique has easy instrumentation and data interpretation, it can be implemented as a routine in the investigation of the elemental composition of foods. In addition, the technique has the advantage of carrying out in situ analyzes by portable instruments. These in situ investigations can even be applied to make quality control of bananas at the time of harvest.

Use of mid infrared spectroscopy to analyze the ripening of Brazilian bananas

“…al., used X-ray fluorescence to characterize the elemental concentrations of two types of banana, gold and silver. Their results showed that elements of both types are more concentrated in the skin than in the pulp (Pereira et al, 2021). In fact, the usage of infrared spectroscopy as an analytical method to determine authenticity and adulteration in food has increased exponentially (Kamal & Karoui, 2015;Pereira et al, 2020;Luiz et al, 2020;Teixeira et al, 2020;Khan et al, 2021;Silva et al, 2021).…”
