Characterization of Satsuma mandarin (Citrus unshiu Marc.) nectar-to-honey transformation pathway using FTIR-ATR spectroscopy
چکیده انگلیسی


- Chemical characterization of nectar-to-honey conversion by FTIR-ATR spectroscopy.
- First record on IR chemical fingerprints of Citrus unshiu nectar/honey sac content.
- Comparative compositional changes in Citrus nectar-to-honey transformation pathway.
- Preliminary results: >1/3 of the sugar-related conversion occurs in the honey sac.

Samples of Satsuma mandarin (Citrus unshiu Marc.) nectar, honey sac content and honey were analyzed by FTIR-ATR spectroscopy and reference methods. The spectral analysis allowed detection of the major chemical constituents in C. unshiu nectar-to-honey transformation pathway thus providing information on the intensity and location of the compositional changes occurring during this process. The preliminary results showed that in average more than one-third of sugar-related nectar-to-honey conversion takes place directly in the honey sac; the average sugar content (w/w) was 17.93% (nectar), 47.03% (honey sac) and 79.63% (honey). FTIR-ATR results showed great spectral similarity of analyzed honey samples and small degree variations in both sugar and water content in nectar samples. The spectral data revealed distinctive differences in the chemical composition of individual honey sac contents with the most intensive and complex absorption envelope in the spectral region between 1175 and 950 cm−1 (glucose, fructose and sucrose absorption bands).
