The influence of the drying temperature (35 and 45C) on bee pollen is evaluated based on the physical, chemical and nutritional characteristics of dried bee pollen from two zones in Colombia (La Calera and Zipaquira). The methods used to establish the effect of the treatment are: determination of chemical composition, measurement of water activity, solubility index, mean particle size, vitamin C content and carotene content. The results confirm that the drying process of bee pollen at 45C has the shorter drying time (156–198 min), moisture content (7–8%) and water activity (0.3), but higher levels of carotene and vitamin C losses. The protein, fiber and ash contents are not affected by the drying temperature. The observed higher carotene content of the pollen from La Calera is probably because of the flora composition in this zone. The vitamin C content decreases as the drying temperature increases, but there are no significant differences between zones.
