“…The presence of both carcinogenic and noncarcinogenic PAH in smoked/grilled foods and wood smoke has been well documented Shubik, 1964,1965;Lijinsky and Ross, 1967;Rhee and Bratzler, 1968;Tilgner and Daun, 1969;Rusz et al 1971; White et al, 1971;Toth and Blaas, 1972;Potthast and Eigner, 1975;Panalaks, 1976;Steinig, 1976; Borys et al, 1977;Obiedzinski, 1977; Obiedzinski and Borys, 1977;Potthast, 1978Potthast, , 1979; Lo and Sandi, 1978; Doremire et al" 1979;Lintas et al, 1979;Binnemann, 1979;Fretheim, 1983; Larsson et al, 1983; Colmsjo et al, 1984; Lawrence and Weber, 1984). Numerous factors can contribute to the formation of PAH in smoke and foods, with several important ones being wood composition, temperature of pyrolysis (Tilgner, 1977), and meat lipid content (Doremire et al, 1979). Recently, mesquite, which is a leguminous plant of the American Southwest, has become quite popular as a fuel source for grilled foods. Its advocates claim that its high combustion temperature gives food a unique flavor and results in a moist product.…”
