As the hazard exists in any tache of food chain, any one of the chain should try his best to control the safety of the food. The safety of the cooked meat products is always one of the most important problems. ISO22000:2005"Food safety management systems-Requirements for any organization in the food chain"offers a standard for the cooked meat products safety management.展开更多

All experiments were conducted using standardized procedures at University of California, Riverside＇s commercial test cooking facility. PM mass emissions collected using South Coast Air Quality Management District（SCAQMD） Method 5.1, as well as a dilution tunnel-based PM method showed statistically significantly reductions for each control technology when compared to baseline testing（i.e., without a catalyst）. Overall, particle number emissions decreased with the use of control technologies, with the exception of control technology 2（CT2）, which is a grease removal technology based on boundary layer momentum transfer（BLMT） theory. Particle size distributions were unimodal with CT2 resulting in higher particle number populations at lower particle diameters. Organic carbon was the dominant PM component（ 99%） for all experiments. Formaldehyde and acetaldehyde were the most abundant carbonyl compounds and showed reductions with the application of the control technologies. Some reductions in mono-aromatic VOCs were also observed with CT2 and the electrostatic precipitator（ESP） CT3 compared to the baseline testing.展开更多
