Twenty-four samples of Apis mellifera honey and twenty-four
samples of Melipona subnitida (Jandaira) honey were collected in the northeast
of Brazil. Moisture, hydroxymethylfurfural, free acidity, insoluble solids in
water, diastase activity, ashes, electrical conductivity, proteins, lipids,
total carbohydrates, energy and sugars were the parameters analysed.
The efficiency of the qualitative tests (Fiehe's test,
Lugol's reaction, Lund's reaction) was tested. Pollen types and the
corresponding plant species were identified in all samples (3 in Apis and 1 in
Melipona).
Apis mellifera honey samples demonstrated parameters in
accordance with the Brazilian Legislation, while the Melipona subnitida honey
samples displayed moisture (24.80%) and diastase activity (null) in discordance
with the established by the regulation for Apis mellifera honeys. Apis honey
samples presented higher values of electric conductivity (284.00 μS cm−1) than
the obtained from the Jandaira honey samples (102.77 μS cm−1) as well as a darker
colour (26.67 mmPfund) when compared with Jandaira honey (7.00 mmPfund).
The concentration of the glucose, fructose and sucrose was
higher in the Apis honeys than in the Jandaira honey. The characteristics of
the two types of honey were very different, highlighting the need of developing
specific legislation for stingless bees' honey.
