I teach science in government school.
I asked students “what is name of gas used in your house stove.? What are its limitation.”
One student said”Madam we use #natural gas in our house stove.When #natural gas burns it releases unhealthy amounts of #pollutant in form of particulate matter , #nitrogen dioxide and #carbon monoxide.”
I said”Roti or chapati are most unique and #fundamental food available in India.They are special in sense they are prepared for lunch and dinner in many families irrespective of #social status.”
Another student said”madam roties look very good as they are rolled in round shape from #wheat floor.”
I said”some persons make roti and bake directly on #gas stove with help of spatula.Baking of roti is completed till it gets #brown puff.In this process of baking roti #temperature goes till 500 degree centigrade.At such a high temperature process of #pyrolysis takes place.There is more emission of #nitrogen dioxide and #carbon dioxide from gas stove.That destruct many #proteins,nutrients and fibers from roties.Including roties made by this procedure in diet of any person increases risk of #cancer.There is risk of #lung and #heart diseases.”
I further added”there is another #procedure of making roties which is much better than previous one.In this procedure #tawa(shown in figure above) is made use of for making roties.Roti on tava are flipped and cooked on both sides.Temperature is #uniform and optimum on tava surface.Moreover there is no possibility of occurrence of process of #pyrolysis .With tava arrangement emission of nitrogen dioxide and carbon monoxide is less.Hence tava roti is more nutritious compare to roti made on direct flame.
MORAL-It is better to make tava roti, It has low fat contents and is very nutritious.
