A comparative characterization of physicochemical and antioxidants properties of processed Heterotrigona itama honey from different origins and classification by chemometrics analysis
: Stingless bee honey produced by Heterotrigona itama from different botanical origins was characterised and discriminated. Three types of stingless bee honey collected from acacia, gelam, and starfruit nectars were analyzed and compared with Apis mellifera honey. The results showed that stingles...

| Summary: | : Stingless bee honey produced by Heterotrigona itama from different botanical origins was
characterised and discriminated. Three types of stingless bee honey collected from acacia, gelam, and
starfruit nectars were analyzed and compared with Apis mellifera honey. The results showed that
stingless bee honey samples from the three different botanical origins were significantly different
in terms of their moisture content, pH, free acidity, total soluble solids, colour characteristics, sugar
content, amino acid content and antioxidant properties. Stingless bee honey was significantly
different from Apis mellifera honey in terms of physicochemical and antioxidant properties. The amino
acid content was further used in the chemometrics analysis to evaluate the role of amino acid
in discriminating honey according to botanical origin. Partial least squares-discriminant analysis
(PLS-DA) revealed that the stingless bee honey was completely distinguishable from Apis mellifera
honey. Notably, a clear distinction between the stingless bee honey types was also observed.
The specific amino acids involved in the distinction of honey were cysteine for acacia and gelam,
phenylalanine and 3-hydroxyproline for starfruit, and proline for Apis mellifera honey. The results
showed that all honey samples were successfully classified based on amino acid content. |
