Abstract

Protein is the most important characteristic component of honey. The types and content of proteins in different kinds of honey are imparity, but those in the same kind of honey are very similar. Capillary zone electrophoresis (CZE) method, used to detect proteins, was developed for authenticating of four mono-floral honeys (n = 45), including medlar honey, chaste honey, jujube honey and locust honey. Electrophoresis conditions including capillary inner diameter (50–70 μm), pH (2.5–9), the concentration of anionic surfactant (0.3–0.5 mmol L−1), injection time (3–7 s) and separation voltage (3–7 KV) were optimized. The results showed that the honey sample was highly stable and the detection limit was 10%, the relative standard deviation of retention time and peak area were lower than 1.40% and 1.76%, respectively. The CZE fingerprints were established on the basis of different protein characteristics in different mono-floral honeys combined with chemometric analysis. All 45 honeys could be correctly identified according to their floral origins. This method does not need to confirm the type of protein, and has the advantages of simple and fast verification of the authenticity of honey.

Abstract

The aim of the study is to discriminate mono-floral honey by the chemical characteristics of non-sugar components (NSC) present in honey based on their botanical origin. The NSC in 50 honey samples including jujube, chaste and locust were determined and compared using HPLC and 1H-NMR combined with chemometrics analysis. The results showed that the content of NSC in jujube honey was the highest, with the average value of 780.77 mg/100 g, followed by locust honey, the lowest was chaste honey, with the average value of 292.43 mg/100 g. HPLC and 1H-NMR fingerprints of mono-floral honey samples were established, in which common chromatographic and spectral peak information were obtained. Principal component analysis and discrimination analysis were performed using selected common peaks as dependent variables and floral origin as independent variables, 44 honey samples and six test samples were correctly classified according to their floral origin.
