| Abstract Pollen is used in the human diet as a food supplement because of its high nutritional value; however, this product is prone to fungal contamination that could potentially generate toxins that are harmful to human health. This study aimed to verify the floral diversity of commercial brands of bee pollen and their mycotoxicological safety for human consumption. A total of 27 bee pollen samples were analyzed; these samples represented commercial brands, either showing an inspection seal or not, marketed in the State of Rio de Janeiro. The analyzed parameters included floral diversity through palynological analysis, water activity, fungal counts, identification and toxigenic profiles. The palynological analysis identified nine plant families, of which... |

| Royal jelly (RJ) is used as a revitalizing tonic. In order to avoid rejection to its acid taste, it is added to honey. There are regulations for honey and for royal jelly separately but not for the mixture. The objective of this work is, therefore, to verify if the same methods used for pure honey quality control can be used for honey mixed with royal jelly and also the presence of RJ through 10-HDA determination. The methods used were: moisture, reducing sugars, apparent sucrose, ash, hydroxymethylfurfural, insoluble solids, diastase activity, acidity and 10-HDA. Samples were prepared by adding 0-100% of RJ in honey. The results showed that the ash method was the only suitable one to all the samples. The acidity analysis (direct titration) was suitable to... |

| This study was carried out to evaluate the effect of bee pollen (BP) levels on the IgG and IgM titers, weight of lymphoid organs, and on the tibia morphometric measures and mineralization in broilers at 21 and 42 days of age. Four hundred birds were used in an entirely randomized design with four treatments (0, 0.5, 1 and 1.5% of BP feed inclusion) and five replicates. At 21 and 42 days of rearing, blood samples were collected for IgG and IgM analysis, as well as lymphoid organs (bursa, thymus and spleen) and the tibiae. There was no effect (p>0.05) of the BP inclusion on IgG titers, bursa and spleen weights, tibia morphometric measures and mineralization at 21 and 42 days, IgM titer at 42 days or thymus weight at 21 days. However, IgM titers at 21 days... |
