Abstract

The aim of the work was to evaluate the authenticity of honey present in Lithuanian market using GC-FID analysis of trimethylsilylated carbohydrates. In total, 15 natural honey samples and one artificial honey sample were analysed. In general, the composition of carbohydrates in the tested samples of natural honey was quite similar, except for trisaccharides, which were not found in any of the analysed samples. Although the amount of identified compounds was different, the percentages of the quantified sugars in natural honey were within the limits established by Codex Alimentarius Commission. Artificial honey contained 9.01% of sucrose and 34.60% of maltose, while the content of maltose in natural honey varied in the range of 0.29–1.41%. The content of fructose and glucose in artificial honey was 2.41% and 22.89%, respectively; while the sum of the main monosaccharides in natural honey was averagely 38.80%. The results obtained indicate that tested natural honey samples from Lithuanian market were genuine products.
