Mineral substances in different types of honey

Determination of the proportion of mineral substances in honey is important not only to determine the quality of honey, as an alimentary product, but also for the reason of honey being one of the best samples to collect information on the current status of environment. On the basis of the mineral substances proportion in honey it's possible to determine botanical and geographical origin of the honey in question which is very important for the consumer protection. 67 samples of honey sorted by their botanical origin have been collected on the territory of the Republic of Croatia in order to establish the proportions of manganese, iron, copper, zinc and phosphorus. Proportion of manganese, iron, copper and zinc are determined by using atomic absorption spectrophotometry method. Proportions of phosphorus are determined by using colorimetry method. Investigations have showed that darker sorts of honey are richer in mineral substances than lighter sorts. The existence of noticeable differences in the proportions of mineral substances within the same sorts of honey has been detected. Between different sorts of honey no significant differences were recognized, so it was impossible to confirm the botanical origin on the basis of available data.
