Perfil do pólen apícola com indicação monofloral

Abstract

The objective of this study was to investigate the physico-chemical, bioactive, microbiological and botanical origin of bee pollen samples with Monofloral indication parameters. Analyses were performed from ten samples of pollen, from the states of Bahia and Sergipe, donated by producers, between the years 2012 and 2014. The physico-chemical analysis revealed the following average values: moisture 8.78%; water activity of 0.42; 3.08% ash, 1.84% lipids; Protein 19.51%; total sugar 28.42%; pH 4.81; acidity 99.78 mEq / kg.1. All physico-chemical parameters, except for the 50% moisture and lipid levels, are within the limits established by Brazilian legislation for bee pollen. The content of total phenolic compounds showed values ranging from 54.91 mg AGE / 100g and 94.32 mg quercetin / 100g respectively. Microbiological analysis revealed the presence of molds, yeasts and aerobic mesophilic above the levels considered safe in 20% of samples, and the presence of indicators of health quality. Only 10% of the samples met all criteria evaluated, considered safe for consumption. The results of the pollen analysis showed little variation between samples of pollen types, resulting in the identification of 08 Monofloral samples, with the kind Cocos nucifera the most representative, being present in 90% of evaluated material, constituting two Monofloral samples. Generally the samples evaluated pollen can be considered nutritionally balanced.
