Determination of volatile characteristics of Greek and Turkish pine honey samples and their classification by using Kohonen self organising maps☆

Some aspects of dynamic headspace analysis of volatile components in honey

“…The higher dispersion associated with the use of 5-nonanone as internal standard (see Table 1) may be due to the selection of a single compound for quantitation of a large number of volatiles within a wide range of volatility and/or to the incomplete homogenization of the internal standard in honey matrix. Tananaki et al (2007) based quantitation on relative data and found standard deviations for volatiles of different characteristics within the same range of those reported in Table 1 for ng g À1 data. The probable existence of trends in dispersion of non-random nature, previously observed in the SPME fractionation of honey volatiles (Soria, García, Martínez-Castro, & Sanz, 2003), should be evaluated in order to determine their influence on the dispersion results above mentioned.…”

“…P&T-GC-MS has been used for characterization of volatile composition of natural and commercial honeys (Overton & Manura, 1994; http://www.sisweb.com/referenc/applnote/app-25-a.htm) and for authentication of honey floral source (Bianchi et al, 2005;Bouseta et al, 1992;Radovic et al, 2001) and geographical location (Tananaki, Thrasyvoulou, Giraudel, & Montury, 2007). The present work was aimed to evaluate and improve several 0963-9969/$ -see front matter Ó 2008 Elsevier Ltd. All rights reserved.…”

Self-organising map rainfall-runoff multivariate modelling for runoff reconstruction in inadequately gauged basins

“…The SOM can be used for many practical tasks, such as the reduction of the amount of training data for model identification, nonlinear interpolation and extrapolation (i.e. prediction), generalisation and compression of information for easy transmission (Kangas & Simula 1995;Kohonen et al 1996;Parasuraman et al 2006;Tananaki et al 2007; The Osun basin in south west Nigeria is highly developed with many water abstractions and impounding schemes as shown in Figure 3. Together with the neighbouring Ogun river basin, the Osun basin is managed by the Ogun-Osun River Basin Authority, one of the 11 statutory river basin organisations in Nigeria.…”

Flavor of Wine

“…Volatiles involved in differentiating the honeys of different botanical origins were also reported. Tananaki et al (2007) analyzed honeys from Greece and Turkey using P&T-GC-QMS. From 77 compounds, two of them [car-3-ene and an unidentified compound (m/z 55, 79, 91, 107, 123, 165)] were found to be specific to Turkish honeys and may be considered as markers characterizing the Turkish origin of samples.…”
