Studies of cooking emissions have been carried out in both real
life kitchens and in controlled environments. It is assumed that in
controlled experimental setups, the measurements are influenced
mainly by the fuel used and the food being cooked while in actual
real life kitchens measurement of emissions are influenced by
many factors such as room arrangement, building materials, outdoor
infiltration, other combustion devices, ventilation, and cooking
methods Visible fumes are generated during the cooking process, which are
usually due to submicrometer sized particles, which consist of oil
droplets, combustion products, steam from water in the food being
cooked and condensed organic pollutants. The particulate matter
(PM) generated is generally within the ultrafine particle (UFP) e
which represents particles of diameter less than 100 nm e and fine
PM (PM2.5) size ranges. The physical stirring of food has been found to
lead to the generation of large aerosols due to the process of splashing
of the ingredients
