Use your pan to save life and energy

I won't babble on the title but I urge you to read my notes below. You can save yourself and save energy and save our world at the same time.

Are there PFAS in Teflon?
PTFE, best known by the brand name Teflon™, is typically made using several hazardous PFAS (per- and polyfluorinated alkyl substances) that have polluted drinking water across the globe.
   
Do all nonstick pans have PFAS?
Some non-stick cookware may claim to not contain any or certain PFAS. Many of these types of cookware do not provide information about what chemicals are used instead. If you must use non-stick cookware, Green Science Policy Institute has compiled a list of PFAS-free products.

Safety of Teflon™ Nonstick Coatings: Non stick pan temperature
https://www.teflon.com/en/consumers/teflon-coatings-cookware-bakeware/safety
Do not use nonstick cookware and bakeware in ovens hotter than 260 °C (500 °F). Higher temperatures can discolor the surface of coating or cause it to lose some of its nonstick properties.
*Chemours does not recommend using cookware coated with Teflon™ nonstick for broiling or cooking at temperatures typically used to broil food (260-288C). To put this warning in simple terms -- Do not fry meats or steaks or fish or pork crackles/skins in non-stick pans/pots. Use steel or iron pans/pots instead.(There are pots/pans that can withstand very high temperture, but you will have to pay much higher price for this property.)

3 Aug 2022 — Today, the family of compounds including Teflon, commonly called PFAS, is found not only in pots and pans but also in the blood of people

PFAS Explained https://www.epa.gov/pfas/pfas-explained  
- PFAS are found in water, air, fish, and soil at locations across the nation and the globe.
- Scientific studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals.

==PFASs owe durability to strong C-F bonds. By heating the compounds in a solvent DMSO --dimethyl sulfoxide (CH3)2SO and a common reagent found in cleaners and soaps, the researchers successfully knocked off the oxygen-containing group. This triggered a cascade of reactions that ultimately broke the compounds down [into harmless products?]. --dish washers can harm non-stick pots and pans and you because of the chemicals used.

==These are common in soap or detergent products. Sodium bicarbonate (baking soda) Sodium hydroxide (lye) Sodium hypochlorite (liquid bleach) Sodium perborate. --residues of these can play a part in breaking down non-stick surface while cooking at high temperature (260Ccor over).

[I recommend cooking on electric stove turn knob about half-full; on gas stove about mark 6 (400F/200C)].

Here your chance to save your health, to save your non-stick utensils and to save energy all at the same time: cook [using non-stick pots and pans] at medium temperature (about 200C) only. Don't leave your non-stick pots and pans on heat for a longer time than necessary and wipe clean the non-stick surface (with a little cooking oil but not using metal scrubber and soap or detergent products) after use before storing them away.

[Adding a journal entry about saving energy with a pressure cooker: 

Pressure Cooker is an energy saving device. It is an application of Gay-Lussac’s law [ P1/T1 = P2/T2; Tx : temperature, Px : pressure; at constant Volume]. It is a steam engine of a simplest kind - when water is heated and turns into steam which is trapped and increases the pressure in the ‘pot’, the temperature in the pot increases and cooks what food in the pot. Less energy is wasted heating air and environment.

For those who can’t wait for the pressure cooker to cool down, put a wet cloth on the lid for a minute to condense the steam (back into water) and reduce the pressure hence the temperature, so no harm (steam burn) will come you, when you open the lid.
