Cooking surfaces

Hard-surface, usually metal, cleaning in which very specific kinds of dirt need to be removed, such as grease on engines, rust on metal parts, or burned carbon on cooking surfaces. The detergents may also need to be biocidal, such as blended non-ionic and quarternary amine surfactants. 

The simplest of all food release agents are found in the category of pan oils or griddle greases. These products contain low levels of lecithin (0.5-1.0%). Most of the release action is provided by the mechanical barrier established by hberaUy coating the cooking surface. 

Serendipity plays a big part in scientific research. The term serendipity means a discovery made by accident. One of the most profitable discoveries made this way is the material Teflon. The name Teflon is the trade name of a type of plastic made by the DuPont Chemical Company. It has become an important commercial product for one main reason very few things stick to Teflon. Most kitchen cupboards probably contain skillets and other pans with cooking surfaces covered with Teflon. Most food will not stick to Teflon-covered pans as it cooks. And foods cooked in Teflon pans need no oil or butter. 

Calculate the area of the cooking surface for each of the three different containers.

Infer the relationship between the cooking surface area and the speed of the chemical reaction happening to the egg. Explain why this relationship exists. 

From the results of this initial survey it became obvious that mutagenicity of protein-rich food was related to the type of food and degree of cooking. In order to study the effect of cooking in more detail and to determine the contribution of major meat constituents to mutagenicity of heated samples/ ground beef patties or reconstituted samples were fried for various times at one or a series of temperatures on stainless steel or other cooking surfaces ). 

Cooking Surface. The mutagenic activities of the basic fraction from hairburger cooked on the different surfaces are shewn in Table 5. Meat cooked on aluminum/ cast iron/ stainless steel and Teflon surfaces contained the highest activity of the samples tested. Meat cooked on the ceramic and enamel surfaces contained less mutagenic activity.

Poly(tetrafluoroethylene) (PTFE), the most significant fluoropolymer, was discovered by Roy Plunkett in 1938 in the laboratories of E.I. du Pont de Nemours Co. Later, in 1950, it was marketed as Teflon . It constituted 60wt% of the world lluo-ropolymer consumption and reached 181.5x10 metric tons in 2008 [81], In 2010, the fluoropolymer industry had revenues of 5.8 billion with use ranging from non-stick cooking surfaces to use in clothing... 

Other P-spodumene solid solution glass-ceramics were developed under the trademarks Cer-Vit (Owens-Illinois) and Hercuvit (PPG) in the United States and in the United Kingdom. The latter was used to produce cooking surfaces (Pincus 1971).
