Surface Colour Changes of Turkish Hazelnut Wood Caused by Heat Treatment
Journal Title: Journal of Advances in Biology & Biotechnology - Year 2016, Vol 6, Issue 1
Abstract
The influence of thermal treatment conditions on natural colour of Turkish hazelnut wood was investigated. It was realized that the elevated temperature and prolonged treatment time usually effects on darker tone on wood samples. However, the greatest lightness (L) changes occurred in 180ºC and 10 hour treatment (37% decreases) followed by 180ºC and 6 hour (25% decrease) and 120ºC and 6 hour (24% decrease) treatment conditions, respectively. Moreover, the greatest changes for coordinate a* (green-red) were also realized at 180ºC and under 10 h treatment conditions. For FT-IR analyses, the heat treated hazelnut sample exhibited the diminished absorption in 900–1200 cm–1 region relative to the polysaccharides where a less complex in-plane C-C vibration was dominant.
