25. How a Huottuja (Piaroa) community perceives genuine and false honey from the Venezuelan Amazon, by free-choice profi le sensory method
Pot honey is the most abundant honey in the forest, produced by many species of stingless bees (Meliponini) of the Huottuja (Piaroa) community in Paria Grande, Venezuela. However, the commercialization of this honey is low, and false honeys, which are sold in labelled bottles, are easily found in the market. This study has investigated the ability of an untr

27. Validação de método para a determinação de 5-hidroximetilfurfural em mel por cromatografia líquida e sua influência na qualidade do produto
In honey 5-hydroxymethyl-2-furaldehyde (HMF) is one of the most typical products of degradation: it is usually absent in fresh honey, but its concentration tends to rise as a result of heating processes or long-term storage. The validation protocol was performed in terms of detection and quantification limits, precision (by repeatability and intermediate pre

28. Caracterização do mel produzido por espécies de Melipona Illiger, 1806 (apidae: meliponini) da região nordeste do Brasil: 1. Características físico-químicas
Thirty three honey samples produced by four Melipona species from different areas of the State of Bahia, were analyzed with the aim to determine their physico-chemical characteristics, contributing to the establishment of standards for quality control. The majority of the average values for physico-chemical parameters fulfilled the quality criteria establish

29. Mel de abelhas nativas e africanizadas do estado de Alagoas : composição química, segurança microbiológica e atividade terapêutica. / Honey of beens native and africanized state of Alagoas State : chemical composition,security microbiological and activity therapy.
The rational development of bees is one of the most promising agricultural activities, since it is essentially self-sustaining family and therefore helps to maintain and restore the environment, through their role in pollination, and guarantee income to the producer who employs his family on it. Honey is the main product of this activity, being generated by

30. NMR and chemometrics on honeys and aguardentes analysis / Utilização da RMN aliada a métodos quimiométricos na análise de méis e aguardentes
A apicultura no Brasil tem-se expandido muito nos últimos anos, tornando este país um dos maiores exportadores mundiais de mel. A cadeia produtiva de aguardente também encontra-se em expansão, firmando esta bebida como um importante produto do agronegócio brasileiro. Por isto, o controle de qualidade destes produtos é indispensável. O presente trabalh

31. Sensorial and instrumental profile of wild honeys of bees africanized (Apis mellifera sp.) of the four micro regions of the State of Piauí. / Perfil sensorial e instrumental de méis silvestres de abelhas africanizadas (Apis mellífera sp.) das quatro mesorregiões do Estado do Piauí.
Este trabalho teve como objetivo avaliar através do perfil sensorial/instrumental, amostras de méis produzidos nas quatro mesorregiões do Estado do Piauí, permitindo conhecer as diferenças entre os atributos de qualidade dos mesmos. Os perfis foram desenvolvidos com 55 méis das quatro mesorregiões deste Estado (Norte, Centro-norte, Sudeste e Sudoeste)

32. Perfil de Substâncias Fenólicas de Méis Brasileiros por Cromatografia Líquida de Alta Eficiência e Avaliação do Potencial Antioxidante. / Phenolics Profile of Brazilian Honeys Through HPLC and Evaluation of Antioxidant Potential.
Avaliou-se a atividade antioxidante para quatro amostras de méis silvestres e cinco amostras de méis de laranjeira, cujos resultados se mostraram satisfatórios tanto para os méis quanto para seus extratos. Os teores de fenóis totais mostraram-se superiores para os méis heteroflorais (silvestres) em comparação com os homoflorais (laranjeiras). Os teor

As botanical and floral origin and depending on the budding, place, climatic conditions and techniques of preparation, the honey can vary in coloration, density, aroma and flavor. The multifloral honey, the most common in such a way in Brazil as north-eastern of this, is due to great diversity of plants. The sensorial properties are the main parameters in th

34. Caracterização físico-química e qualidade microbiológica de amostras de mel de abelhas sem ferrão (Apidae, Meliponinae) do Estado da Bahia, com ênfase em Melipona Illiger, 1806 / Physico-chemical characterization and microbiological quality of stingless bees (Apidae, Meliponinae) honey samples from the State of Bahia, Brazil, with emphasis on Melipona Illiger, 1806
The stingless bees honey is a product presenting a growing market demand but, in spite of its consumption as food and even medicinal use, there are few studies to define quality standards for its commercialization. This work was carried out to determine the physico-chemical characteristics and microbiological quality of honey samples produced by meliponid sp

35. Contenido de flavonoides y compuestos fenólicos de mieles chilenas e índice antioxidante
A comparison of the phenolic content of several Chilean honeys showed great variations in flavonoid concentration among the samples analysed. Higher amounts of phenolics are found in honey from dry climates. The antioxidant effect of extracts, using ORAC analysis, did not correlate with the flavonoid content or with the total phenolic concentration.

36. Prebiotic and Antimicrobial Properties of Honey Bee. / Propriedades Prebióticas e Antimicrobianas de Mel de Abelha.
The prebiotics are non-digestible food components that improve host health by selectively stimulating, the growth and/or activity of desirable bacteria populations in the colon, such as bifidobacteria and lactobacilli. It is believed that honey bee may exert a prebiotic effect on the microbial population of the colon as it contains a series of oligosaccharid
