Abstract

The contents of holocellulose, one of the main components of the wood, were 83.9% in oak wood and 76.9% in apple wood, respectively. Those of hemicellulose were 16.41 and 20.33%, and in lignin 23.0 and 19.7%, respectively. Six species of domestic oak wood and apple wood were considered to be suitable for smoking materials due to the low content of lignin. Benzo(a)pyrene contents in smoke flavoring prepared with oak wood at 150, 400 and 500$^{\circ}C$ were 0. 4, 3. 7 and 5.6$\mu\textrm{g}$,/kg, respectively. The amounts of phenanthrene were 112.7, 131.4 and 255.9$\mu\textrm{g}$/kg, respectively, in each temperature. The amounts of polycyclic aromatic hydrocarbons(PAH) in smoke flavory were in the order of phenanthrene>anthracene>pyrene>benzo(a)anthracene>chrysene>benzo(b)fluoranthens>benzo(a)pyrene Benzo(a)pyrene contents in smoking extracts prepared with apple wood at 150, 400 and 500$^{\circ}C$ were 0.4, 3.3 and 5.5$\mu\textrm{g}$/kg, respectively. Phenanthrene contents in those samples were 72.7, 100.2 and 220.5$\mu\textrm{g}$/kg, respectively. Contents of each PAH showed the same order as in oak wood.
