Abstract
Honey is the sweet substance made when the nectar and sweet deposits from plants are gathered, modified and stored in the honeycomb by honey bees. Pollen is the male reproductive cells of flowers. The objectives of the study were to investigate the botanical origin, physicochemical and antioxidant proprieties of West Shoa honey and pollen of Ethiopia.The physicochemical properties of those honeys were determined using moisture content, electrical conductivity, PH, ash, free acidity, Hydroxymehylfurfural, sugar, total protein content and fat for different types of honeys and the proximate composition of pollen was analyzed. The antioxidant content and antioxidant activities of the honey and pollen were evaluated. The botanical origin found were Trifolium species, Guizotia scraba, Eucalyptus globulus and Multiflora honey. Plantago lanceolata and Eucalyptus globulus were used pollen characterization. The highest moisture content were seen in Trifolium spp honey (16.54 ± 1.68%) while that of multiflora honey had lowest moisture content (15.65±0.93%). The highest total phenolic content recorded in multiflora honey (196.54±6.47 mg of GAE/100g) and the highest ferric reducing antioxidant power recorded in Guizotia scabra honey (70.76±4.79). The highest radical scavenging activity content recorded in Plantago lanceolata pollen (70.71±0.39%).Accordingly it is possible to state that West Shoa honey and pollen are good quality honey and pollen in relation to the physicochemical and a high antioxidant source of food.
