The aim of this study was to obtain data on the production and verify the adequacy, based on Brazilian legislation, of practices adopted during the processing of bee-pollen collected in nine Brazilian states; and, to identify the perception of the beekeepers about the vegetation visited by bees. The data were obtained from the beekeepersusing a questionnaire and, in the laboratory, the moisture content and the botanical origin of the 69 samples were identified. It was observed that the number of productive hives per apiary ranged from 3 to 300.The frontal type collector was used by all producers who answered this question. The interval between the collection and the dehydration of the samples varied between apiaries and only two samples were lyophilized, while the others were dehydrated in an electric oven. Part of the samples was dehydrated under temperature above the limit established in Brazilian legislation, and 91% of the analyzed products had moisture content above 4%. No food additives were used at any stage of the process. Pollen analysis indicated that, in some cases, the producers were able to identify the plants visited by bees. It is concluded that, the production of bee-pollen was performed by small or medium beekeepers, which adopt different practices of production and processing, respecting the non-use of additives, however, with failures in terms of dehydration temperature and moisture content in the final product. Moreover, when producers carefully observe the collection of pollen by bees, they are able to perceive the polliniferous sources. [ABSTRACT FROM AUTHOR]

Twenty-four samples of Apis mellifera honey and twenty-four samples of Melipona subnitida (Jandaira) honey were collected in the northeast of Brazil. Moisture, hydroxymethylfurfural, free acidity, insoluble solids in water, diastase activity, ashes, electrical conductivity, proteins, lipids, total carbohydrates, energy and sugars were the parameters analysed. The efficiency of the qualitative tests ( Fiehe's test, Lugol's reaction, Lund's reaction) was tested. Pollen types and the corresponding plant species were identified in all samples (3 in Apis and 1 in Melipona). Apis mellifera honey samples demonstrated parameters in accordance with the Brazilian Legislation, while the Melipona subnitida honey samples displayed moisture (24.80%) and diastase activity (null) in discordance with the established by the regulation for Apis mellifera honeys. Apis honey samples presented higher values of electric conductivity (284.00 μS cm−1) than the obtained from the Jandaira honey samples (102.77 μS cm−1) as well as a darker colour (26.67 mmPfund) when compared with Jandaira honey (7.00 mmPfund). The concentration of the glucose, fructose and sucrose was higher in the Apis honeys than in the Jandaira honey. The characteristics of the two types of honey were very different, highlighting the need of developing specific legislation for stingless bees' honey. [ABSTRACT FROM AUTHOR]
