ABSTRACT
BACKGROUND: Honey from Tiúba stingless bees (Melipona fasciculata) produced in three different ecosystems in Brazil (Cerrado, Litoral and Baixada), as well as a sample of honey from Apis mellifera bees from the Baixada region for comparison, were evaluated regarding viscosity, color, sensory profile and sensory acceptance. RESULTS: The honey from Tiúba was less viscous, with a darker color and lower purity of the color (chroma) in relation to honey from Apis mellifera. The sensory profile firmly differentiates the honeys. The Apis honey was mainly described as opaque, viscous and adhesive. Tiúba honey from the Cerrado region stood out as semi-bright, acid taste, alcoholic, propolis, bitter taste and spicy. Tiúba honey from the Litoral region was characterized by its yellow color, woody odor and medicine flavor. The Tiúba honey from the Baixada region was described as gold colored, fluid and citric. The Tiúba honey from the Cerrado region had similar sensory acceptance to the Apis honey, probably because it was specifically characterized through attributes of odor and flavor. On the contrary, the Tiúba honey from the Litoral and from the Baixada regions was less well accepted. CONCLUSION: The honeys are different regarding their physical and sensory properties, differences that result from the bee species and from the geographical origin of the honey. This study could contribute to the creation of a standard identity and specific quality for Melipona fasciculata honey, also contributing to its production and commercialization not only in Brazil, but also internationally. © 2020 Society of Chemical Industry.

ABSTRACT: The honey from Tiúba bees (Melipona fasciculata) is commercially important in the Brazilian state of Maranhão. However, the absence of any specific legislation for this kind of honey is an obstacle to its increased production and commercialization. Determining the microbiological and physical-chemical characteristics of different Tiúba honey can inform the elaboration of specific legislation. Thus, honey samples from two Water Catchment Areas in Maranhão (Munim and Pericumã, sample size 20 for each) were collected and submitted for microbiological analysis (total coliforms, thermotolerant coliforms, molds and yeasts, Clostridium sulfite reducers and Salmonella sp.) and physical-chemical analysis (moisture content, reducing and non-reducing sugars, insoluble and soluble solids, ash content, acidity and pH). Most of honeys sampled were suitable for human consumption, except for one sample from Pericumã. Honeys from the two water catchment areas presented differences in some physicochemical characteristics, which can be attributed to the botanic, soil and climatic diversity of the two areas. Still, these Tiúba honey samples did not fall within the Brazilian legislation for Apis mellifera honey for some of the physical-chemical characteristics, and so is not properly regulated, thus reinforcing the need for specific legislation for this type of honey.
RESUMO: O mel de Tiúba (Melipona fasciculata) tem importância comercial na região do estado do Maranhão, no entanto a ausência de uma legislação específica para este mel entrava a ampliação de sua produção e comercialização. Dessa forma, faz-se necessário determinar as características microbiológicas e físico-químicas de méis de Tiúba, com o objetivo de fornecer subsídios para a elaboração de uma legislação específica. Assim, amostras de méis provenientes de duas bacias hidrográficas do Maranhão (Munim n = 20, e Pericumã n = 20) foram coletadas e submetidas às análises microbiológicas (coliformes totais, coliformes termotolerantes, bolores e leveduras, Clostridium sulfito redutores e Salmonella sp.) e físico-químicas (umidade, açúcares redutores e não redutores, sólidos insolúveis e solúveis, cinzas, acidez e pH). A maioria dos méis apresentou-se adequado microbiologicamente ao consumo humano, exceto uma amostra de mel proveniente de Pericumã. Os méis provenientes das duas bacias hidrográficas apresentaram diferenças em algumas características físico-químicas, o que pode ser atribuído à diversidade botânica, edáfica (solo) e climática das duas bacias. Ainda, os méis de Tiúba não se adequaram à legislação brasileira de Apis mellifera para algumas características físico-químicas, o que não permite sua regulamentação e, assim, reforça a necessidade de legislação específica para este tipo de mel.
