Investigation of the storage time on color properties and chemical compositions of particle board made from bagasse

This study was carried out to investigate the effect of storage time on the color properties and chemical compounds of the particle board made from bagasse. For this purpose, the three levels of stored and non-stored bagasse from karoon particle board Company were investigated. In addition, the chemical compositions were determined according to the TAPPI test methods and also biometrical (slenderness ratio) was done with using franklin method. The results showed that the amount of lignin was different in the stored samples at three levels. But the difference amount of cellulose and extractive was not observed. The results illustrated that the color changes in the stored bagasse were more than non-stored one. Identification of the microorganisms in stored samples was done and results showed that the most of them were bacteria and the yeast. The results showed that the storage time can significantly effect on the color and physical properties of stored bagasse.
