| Popis: | Melipona scutellaris Latreille, 1811 is of economic importance for local beekeepers, besides its relevance in the pollination of native plant species of the Brazilian Atlantic forest. Currently, data on the use of floral resources by Meliponini colonies are scarce, particularly in urban environments. We evaluated the botanical origin, the microbiological and physicochemical characteristics of pollen stored by M. scutellaris in colonies in an urban environment. The samples (n = 44) were obtained from the metropolitan region of Salvador, Bahia, Brazil, a region of intense urban and industrial activities. We identified 52 pollen types belonging to 21 botanical families. The botanical families Fabaceae, Myrtaceae, and Anacardiaceae represented most pollen types. Aerobic psychrotrophic bacteria, Bacillus spp., molds and yeasts, fecal coliforms, Escherichia coli, Staphylococcus aureus, sulfite-reducing Clostridium, and Salmonella spp. were not found in the samples. We identified and quantified fatty acids with carbon numbers varying from C4 to C20. For the physicochemical parameters, the following variations were verified: moisture (47.3% to 55.70%), ash (3.45% to 5.90%), protein (10.19 to 24.02%), pH (3.28 to 3.99), acidity (237.20 to 557.10 meq/kg), lipids (2.43 to 7.94%), carbohydrates (10.85 to 28.89%) and total energy value (170.60 to 216.99 kcal/100g). Pollen stored (“samburá”) by bees is a complete food and a source of nutrients with therapeutic potential. Pollen stored by M. scutellaris consists of a heterofloral pollen with physicochemical and microbiological qualities, considered safe for human consumption. Moreover, it contains linoleic and linolenic essential fatty acids making it a potential nutraceutical product.
