Identification of botanical origin of Chinese unifloral honeys by free amino acid profiles and chemometric methods
The amino acid contents of five floral sources Chinese honeys (jujube, rape, chaste, acacia, and lungan) were measured using reversed phase high-performance liquid chromatography (RP-HPLC). The results showed that proline was the main amino acid in most of the analyzed samples. Phenylalanine presents at the highest content in chaste honey samples, and the total amino acid contents of chaste hon...
متن کاملCharacterization of Chinese Unifloral Honeys Based on Proline and Phenolic Content as Markers of Botanical Origin, Using Multivariate Analysis.
The phenolic and proline content were determined in honey samples of different floral origins (rapeseed, sunflower, buckwheat and Codonopsis) from five different regions of China. The phenolic and proline profile of these samples were used to construct a statistical model to distinguish honeys from different floral origins. Significant differences were identified among the studied honey samples...
متن کاملCharacterization of Botanical and Geographical Origin of Corsican “Spring” Honeys by Melissopalynological and Volatile Analysis
Pollen spectrum, physicochemical parameters and volatile fraction of Corsican "spring" honeys were investigated with the aim of developing a multidisciplinary method for the qualification of honeys in which nectar resources are under-represented in the pollen spectrum. Forty-one Corsican "spring" honeys were certified by melissopalynological analysis using directory and biogeographical origin o...
متن کاملDETERMINATION OF BOTANICAL ORIGIN OF HONEY BY MID INFRARED SPECTROSCOPY (Mid-FTIR), COLORIMETRY AND CHEMOMETRIC ANALYSIS
The aim the investigation reported is to determine the potential of determining the botanical origin of honey by a combination of middle infrared spectroscopy, colorimetry and chemometric analysis. Forty-three samples from three types of honey (acacia, linden, and honeydew) are subjected to Fourier transform mid-infrared (Mid-FTIR) spectroscopy. Transmittance spectra with wave numbers from 600 ...
متن کاملChemometric methods for botanical classification of Chinese honey based on the volatile compound profile
This study develops a method for the discrimination and prediction of honey samples from various botanical origins. The method was based on the nontargeted volatile profiles obtained by solid-phase microextraction and gas chromatography-mass spectrometry (SPME-GC/MS) combined with chemometrics. The blind analysis of nontargeted volatile profiles was carried out by SPME-GC/MS for 87 authentic ho...
