Key research conclusions:
● Consumers want to know where their honey comes from, and labeling is important to protect them from misrepresentation and price variations due to different origins.
● Trace metals in honey can vary by location, making spectroscopy and chemometric techniques useful for verifying the origin of honey.
● This study looked at stingless bee honey from different regions and seasons in Peninsular Malaysia to determine their trace metal concentrations using ICP-OES.
● Principal component analysis (PCA) was used to recognize patterns in the data, and linear discriminant analysis (LDA) was used to classify the honey samples by their origin.
● The combination of ICP-OES, PCA, and LDA allowed for accurate classification of the Malaysian stingless bee honey samples by their origin, with high cross-validation accuracy.
● This study provides information on the distribution of trace metals in stingless bee honey samples and can be used as a reference for verifying their origin and authenticity.
