Multi-elemental analysis by FRXDE on pollen produced by the native bee Scaptotrigona aff. postiça

Abstract

Brazil is one of the largest suppliers of bee products in the world. It is currently the 5th largest exporter of honey and derivatives and  a significant part of its production originates from the south and northeast. Specifically, the species Scaptotrigona aff. postica, from the region of Barra do Corda in the State of Maranhão (MA), produces pollen which is one of the main activities of the local economy (food supplement). However, there are no data on its mineral composition, although there is a history of applications in the nutritional field. In this context, this research aims to generate integrated and interdisciplinary knowledge of the pollen produced by this pollinating species, through multi-element investigation (identification and quantification of chemical elements) using the Energy Dispersive X-ray Fluorescence (XRF) technique. The elemental composition of pollen emphasizes its nutritional relevance (Ca, Cl, Fe, K, Mn and P) and  the results of the concentrations showed little seasonal variation, serving as a model for the safe expansion of meliponiculture in the region. In the technological sphere, this analysis is a tool for tracking (provenance), which allows the identification of fraud and/or adulteration, in addition to adding quality control to its commercialization.
