“…Three Amazonian species of Melipona showed protein content between 15.7 and 23.8 (mean 19.5%) (Souza et al, 2004). Rebelo et al (2016) obtained the protein percentage mean values of 24 (for M. interrupta) and 37.63 (M. seminigra). Costa and Venturieri (2009) verified different results due to protein content in diets.…”

“…The knowledge is still limited to their general composition such as protein, carbohydrates and lipids content; nothing is known about micronutrients. This is an important gap to find better ingredients to complement their nutritional needs (Silva et al, 2006;Rebelo et al, 2016;Hartfelder & Engels, 1989;. Several alternative foods have been tested as protein substitutes.…”

Nectar and pollen are the basic food resources of stingless bees. The current advance of meliponiculture led to the search for supplementary feeding. Despite little is known about native bee supplementation, several alternative foods have been tested as protein substitutes, with soy being one of the most commonly used. In this study, we compared the effect of a semiartificial soy-based diet versus a natural diet on the longevity of adult worker of Melipona flavolineata Friese and Scaptotrigona aff. postica (Latreille). A total of 200 workers of each species (40 from each colony) were used, of which 100 comprised the control group (consumed honey and pollen) and 100 the experimental group (honey and a semiartificial food based on soybean extract). The workers were divided into groups of 20 individuals confined in MDF boxes not completely enclosed, without a queen, and kept in BOD incubators. Dead bees were counted and removed daily. Kaplan-Meier survival curves were plotted for each species. We found greater longevity in workers who consumed only natural pollen (71 days for M. flavolineata, 78 days for S. aff. postica, in average) compared to those consuming the soy-based diet (62 days for M. flavolineata, 61 days for S. aff. postica, in average). Workers of M. flavolineata that consumed pollen lived nine days more (21.8%) than those fed on the soy-based diet, while S. aff. postica workers lived seven days more (12.7%). As longevity was only slightly reduced, we can recommend a soy-based diet for stingless bees during dearth periods or for supplemental feeding of newly formed colonies.

“…Essas bactérias são normalmente adicionadas ao pólen a partir do estômago e do mel das abelhas. Para o conteúdo de carboidratos (57,30% a 74,8%) e valor energético (350,94 a 404,59 kcal), ambos corroboraram com os resultados apresentados para os pólens armazenados por abelhas sem ferrão do gênero Melipona no estado do Amazonas (REBELO et al, 2016). Quanto aos valores de compostos fenólicos totais e flavonoides, foi observada grande variação entre as amostras de M. scutellaris e demais espécies.…”

“…Portanto, os constituintes químicos dos pólens podem ser benéficos na prevenção de doenças em que os radicais livres estão envolvidos, e também pelo fato de serem potentes agentes antibacterianos (ISIDOROV et al, 2015), antioxidantes naturais (DE FLORIO ALMEIDA et al, 2017) e de atuarem como quimiopreventivos (OMAR et al, 2016). Devido a sua importância, estudos direcionados para as caracterizações química e biológica têm sido realizados com os pólens armazenados de diferentes espécies de abelhas, incluindo as abelhas sem ferrão (VIT et al, 2016;REBELO et al, 2016).…”

Resumo O estudo foi realizado com o objetivo de verificar tanto a condição microbiológica quanto as diferenças físico-químicas existentes em pólens armazenados por diferentes espécies de abelhas sem ferrão no Nordeste do Brasil. Os pólens armazenados foram coletados nas colônias mantidas em meliponários das seguintes espécies: Melipona subnitida, M.scutellaris, M. mandacaia, Scaptotrigona sp. e Frieseomellita varia. Com relação às análises de qualidade microbiológica, as mesmas foram realizadas em micro-organismos indicadores de qualidade comercial (mesófilos, bolores e leveduras), qualidade sanitária (Staphylococcus coagulase positiva, coliformes fecais e Escherichia coli), e de segurança (esporos de Clostridium sulfito redutores e Salmonella spp.). Para os parâmetros físico-químicos, os mesmos foram avaliados de acordo com a exigência do Regulamento Técnico (RT) de qualidade para pólen apícola, e também para compostos fenólicos. Todas as amostras apresentaram condição microbiológica de acordo com as recomendações aceitáveis para o consumo humano. Os resultados confirmaram as diferenças na composição físico-química do pólen armazenado das cinco espécies; no entanto, houve formação de três grupos de pólens armazenados com base nos parâmetros físico-químicos. As amostras da espécie M. scutellaris apresentaram conteúdo de compostos fenólicos cinco vezes mais elevado aos outros méis das espécies avaliadas. Logo, este estudo permitiu conhecer a composição dos pólens armazenados por abelhas sem ferrão, por conseguinte reforçando a necessidade de reformular o Regulamento Técnico (RT) existente no Brasil para pólen apícola, de forma a abranger os pólens armazenados das espécies nativas.

Nutritional composition and bioactive compounds of Melipona seminigra pot‐pollen from Amazonas, Brazil

BACKGROUND Pot‐pollen is a fermented product stored by stingless bees in cerumen pots and traditionally used as food or medicine by natives in tropical regions. Knowledge of pot‐pollen composition from the Amazon region is important to strengthen the breeding of native bees and consequently contribute to sustainable development in this region. The aim of the present study was to determine the chemical composition of Melipona seminigra pot‐pollen from Amazonas, Brazil. RESULTS We report the identification of 21 phenolic compounds using ultra‐performance liquid chromatography– electrospray ionization–quadrupole time‐of‐flight–mass spectrometry. Overall, the predominant constituents of pot‐pollen were protein (333.8–470.7 g kg−1) and dietary fibers (247.6–353.3 g kg−1). The predominant fatty acids were polyunsaturated (44.95–59.57% of total fatty acid content) and the samples contained all essential amino acids. Total carotenoid content ranged from 3.2 to 48.0 μg g−1, total flavonoid content (as catechin equivalents) from 1.9 to 4.5 mg g−1, total reducing capacity (as gallic acid equivalents) from 7.0 to 15.0 mg g−1, ferric‐reducing antioxidant power from 2.8 to 8.9 μmol g−1 and oxygen radical absorbance capacity (as Trolox equivalents) from 224.9 to 1117.0 μmol g−1. CONCLUSIONS This study reports for the first time a comprehensive chemical characterization of M. seminigra pot‐pollen. The samples presented antioxidant activity, high values of nutrients and bioactive compounds such as polyphenols, carotenoids, insoluble dietary fibers, polyunsaturated fatty acids, and essential amino acids, comparable to other health foods. © 2021 Society of Chemical Industry
