- Antioxidants activity and physicochemical properties of honey from social bees of the Brazilian semiarid regionPublication . Silva, Irana Paim; Caldas, Maiara Janine Machado; Machado, Cerilene Santiago; Nascimento, Andreia Santos do; Lordêlo, Maurício Santana; Bárbara, Marivalda; Evangelista-Barreto, Norma Suely; Estevinho, Leticia M.; Carvalho, Carlos Alfredo Lopes de; Silva I.P.This study compared the nutraceutical potential of Apis mellifera and Melipona quadrifasciata anthidioides honeys from the semiarid region of Bahia, Brazil, using microbiological, melissopalynological, and physicochemical techniques. Total phenols and flavonoids and the antioxidant activity were also determined. All samples had good microbiological quality and safety with an absence of coliforms, Escherichia coli, Salmonella spp., Staphylococcus coagulase positive and Clostridium sulphite reducing spores. Were identified 41 pollen types belonging to 23 botanical families. Myrtaceae, Anacardiaceae, and Sapindaceae were the predominant pollen types in A. mellifera honey, while honey Malvaceae was the most representative in the M. q. anthidioides. Regarding the physicochemical parameters evaluated, 75% complied with the standards established by the Brazilian and European quality legislation. The honey samples of A. mellifera had higher values of phenolic compounds and flavonoids (260.0 to 341.51 mgGAE.kg−1 and from 114.44 to 216.29 mgQE.kg−1, respectively). The samples from M. q. anthidioides presented higher antioxidant activity. The honeys of A. mellifera and M. q. anthidioides from the semiarid regions presented distinct botanical compositions, suggesting that both species use different plant sources, which possibly influenced the parameters related to honey quality as well as the content of phenolic compounds.
- Botanical origin, microbiological quality and physicochemical composition of the Melipona scutellaris pot-pollen (“samburá”) from Bahia (Brazil) RegionPublication . Oliveira, Daiane de Jesus; Santos, Daiane Rodrigues dos; Andrade, Brunelle Ramos; Nascimento, Andreia Santos do; Silva, Macela Oliveira da; Mercês, Carize da Cruz; Lucas, Cátia Ionara Santos; Silva, Samira Maria Peixoto Cavalcante; Carvalho, Paula Dib de; Silva, Fabiane de Lima; Estevinho, Leticia M.; Carvalho, Carlos Alfredo Lopes deMelipona 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.
- Pollen spectrum of honey of Apis mellifera L. and stingless bees (Hymenoptera: Apidae) from the semi-arid region of Bahia State, BrazilPublication . Santos, Polyana Carneiro dos; Nascimento, Andreia Santos do; Sodré, Geni da Silva; Carvalho, Carlos Alfredo Lopes de; Alves, Rogério Marcos de Oliveira; Ferreira, Mariza Alves; Andrade, Brunelle Ramos; Caldas, Maiara Janine Machado; Nunes, Lorena Andrade; Estevinho, Leticia M.Pollen in honey reflects its botanical origin and melissopalynology is used to identify origin, type, and quantities of pollen grains of the botanical species visited by bees. This study aimed to identify the pollen spectrum of honeys from Apis mellifera and stingless bees produced in the semi-arid region of Bahia, Brazil. We analysed 78 honey samples, which were submitted to the acetolysis process for identification and quantification of pollen types. Fabaceae, Asteraceae and Euphorbiaceae were the most predominant families in pollen types. For Fabaceae, the most representative pollen types were Chamaecrista 1, Mimosa caesalpiniifolia, Mimosa pudica, Mimosa tenuiflora, Prosopis and Senna. The results indicate that the flora explored by the bees to collect nectar is diverse in the semi-arid region of Bahia and the honeys analysed were classified as multifloral.
- Use of the electronic tongue as a tool for the characterization of Melipona scutellaris Latreille honeyPublication . Nascimento, Andreia Santos do; Silva, Fabiane de Lima; Machado, Cerilene Santiago; Silva, Samira Maria Peixoto Cavalcante; Estevinho, Leticia M.; Dias, L.G.; Carvalho, Carlos Alfredo Lopes deThis study aimed to characterize honey of Melipona scutellaris regarding its physicochemical parameters using the electronic tongue (e-tongue) technique combined with the multivariate statistical analysis for honey differentiation. Physicochemical parameters were evaluated following official methods of chemical analyses. A potentiometric electronic tongue with 16 cross-sensitivity sensors was used for the analysis. The Principal Component Analysis and the Cluster Analysis distinguished two groups for the sample set in the evaluation of physicochemical parameters, similar to results found using the electronic tongue. We verified a correlation greater than 0.70 between the profile of potentiometric signals and values of pH, ashes, electrical conductivity, HMF, diastase activity, reducing sugars, and apparent sucrose. The combined use of the electronic tongue with the statistical analysis showed the similarity between samples through the formation of two groups of the sample set. The electronic tongue may be used as a complement to traditional techniques of analyses to determine honey physicochemical parameters, constituting a promising tool in association with the multivariate statistical analysis.
