Abstract

Currently, the favorable market for the consumption of natural products, complementary to the diet or with therapeutical effects, has been promoting and stimulating the bee pollen production in Brazil. However, being a recent product its do not presents the complete quality ratings. The pollen is essential in the colony diet, promoting the necessary nutrients for larval growth, metamorphosis and adult development and its activities. Thus, it becomes essential to know the bromatological profile of bee pollen produced in one determinate region, as strategies to feed swarms in the periods of production as in the food shortages. The goals of this work are to verify the seasonality effect in production and bromatological profile of bee pollen and relate its size of acorns of pollen produced by Apis mellifera L., at different periods of the year. The pollen will be collected of five hives, standardized how much to the number of frames and brood, through the frontal collector of bee pollen. The collects will occur three times a week to not interfere with the protein needs of swarms. The bee pollen collected will be mixed, weighty in analytical balance, dehydrated, cleaned and the acorns classified by a set of sieves with different meshes. The samples are stored in steriles vials, which will be kept under refrigeration (7oC) for the accomplishment of bromatologicals analyzes (total protein, fiber, lipids, ash and total sugars). The results will be compared by ANOVA, followed of the test of Tukey to verify differences between the averages. It was considered as statistical different when p<0.05. The results also will be evaluate by Correlation of Pearson to verify the existence of relations between the variable analyzed. (AU)
