The study was carried out to screen mutagenicity of smoking materials for the determination of optimum smoking temperature for meat products. Wood materials employed for smoking were oak and apple trees. Temperatures of the generator for manufacturing of smoke flavoring were set to 250, 400 and 500, respectively. Mutagenic activities of smoke flavoring were assayed according to Ames test using Salmonella typhimurium TA98 and TA 100. In oak wood smoke flavoring, Salmonella typhimurium TA98 without S-9 mix showed strong mutagenic activities at the concentration of 6/plate(250), 4/plate(400) and 6/plate(500). Salmonella typhimurium TA100 with S-9 mix showed strong mutagenic activities at the concentration of 10/plate(250), 20/plate(400) and 10/plate(500). Salmonella typhimurium TA98 with S-9 mix showed strong mutagenic activities at the concentration of 30/plate(250), 40/plate(400) and 20/plate(500). Salmonella typhimurium TA100 with S-9 mix showed strong mutagenic activities at the concentration of 30/plate(250), 50/plate(400) and 20/plate(500). Salmonella typhimurium TA100 without S-9 mix showed strong mutagenic activities at the concentration of 10/plate(250), 20/plate(400) and 20/plate(500). Salmonella typhimurium TA98 with S-9 mix showed strong mutagenic activities at the concentration of 30/plate(250), 40/plate(400) and30/plate(500). Salmonella typhimurium TA100 with S-9 mix showed strong mutagenic activities at the concentrations 30/plate(500). Salmonella typhimurium TA100 with S-9 mix showed strong mutagenic activities at the concentration of 30/plate(250), 20/plate(400) and 30/plate(500). From these results, it could be concluded that optimum smoking temperature for meat products should be set below 400, that the compounds like benzo[a]pyrene etc. contain a variety of mutagenic potentials, which could be generated at the higher smoking temperature.
