Abstract - Determinations of diastatic activity in 12 groups of unifloral honey were made to study variability according to the botanical origin of the honey. Robinia, Citrus, Erica, Taraxacum and Arbutus honeys were found to have a very low enzyme content. On the contrary Hedysarum, Castanea, Honeydew, Eucalyptus and Thymus honeys showed high diastase activity. The relationship between the absorbance at 5 min and the diastatic index was quantified.
Key words: honey / enzyme activity / amylase / absorbance
