Abstract

Some aspects in the physico-chemical properties of pollen such as percent moisture content, crude protein content and crude fat content were determined from pollen collected from the hives of European bees Apis mellifera. The experimental hives were located in Laguna (Alaminos and Sta. Cruz), Batangas (Lipa and Malvar) and Quezon (Tiaong and Dolores). Percentage moisture of the pollen samples ranged from 24.31 ± 0.06 (Tiaong) to 34.44 ± 0.59 (Dolores) with an average of 18.45 ± 0.42 crude protein ranged from 6.29 ± 0.45 (Tiaong) to 20.32 ± 0.98 (Sta. Cruz) with an average of 12.03 ± 1.63 and percentage crude fat ranged from 0.46 ± 0.04 (Dolores) to 2.99 ± 0.16 (Lipa) with an average of 1.71 ± 0.18. Identification of the botanical origin of the bee pollen samples was accomplished by mounting the acetolysed bee pollen samples on a microscope and counting the frequency of each pollen type. Mimosa pudica was the most predominant pollen among the twelve identified plant pollen sources. Differences in percentage moisture of the samples were accounted to the temperature of the sampling site during sample collection. Through statistical analysis, town differences in percentage crude protein and percentage crude fat was found to be not related to the botanical origin of the pollen sample.
