Chemical analysis and identification of pollen grains from different Jordanian honey samples

Abstract

Studies on eight samples of Jordanian honey of known origin included chemical, physical, trace element and heavy metals analysis as well as pollen identification. Results indicated that the quality of Jordanian honey was different depending on processing conditions; the composition of the different types of active compounds that they contain is dependant on the pollen grains that are present. Pollen composition was directly related to the plants on which the honeybees fed. Identification of pollen grains suggested that there were differences in the plants and therefore differences in the composition of the active compounds. Measurements of some trace elements also indicated differences that would affect the quality of the honey samples. Testing the honey samples for the presence of lead and cadmium was used as evidence of pollution. The results reaffirm the presence of heavy metals, giving a warning of pollution in the areas from where pollen is collected.
