Q.19: Oil and fat containing food items are flushed with nitrogen. Why ?

 

Answer:-



Nitrogen being an inert gas does not react easily with the oil and fat present in the food substances. But oxygen reacts easily with the food substances and makes them rancid.  It is because of this reason that food items containing oil and fat are flushed with nitrogen gas before their packing to remove oxygen present in the pack.
