Enzymes Activity Study Of Multiple Types Of Iraqi Honey

Abstract

This study was carried out on samples of honey that represented most of the governorates of Iraq from different plant sources and
included the following: The protein content study of the different honey varieties was studied and it was noted that there were significant
differences at the p<0.05 level in the percentages of protein. It was noted that the protein percentage ranged between 0.14-0.73% and
the highest percentage was in the sample H12 and the lowest In the sample H15.
The results of tests to determine the values of the enzyme activity of honey enzymes (diastase, invertase and glucose-oxidase) showed
that there were significant differences for these values between types of honey, as the highest value of diastase in sample H12 was 21
unit and the lowest value reached 8 units in samples H4 and H8, in While the highest activity of invertase was recorded in the H7
sample which amounted to 284.3 U/kg and the lowest activity in the H11 sample, which amounted to 107.5 U/kg, while the activity of
glucose-oxidase was the highest in the H12 sample amounting to 133.5 micrograms H2O2/g/h and the least effective in the H11 sample
reaching 72.2 micrograms H2O2/g/h
