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

Question:

Oil and fat-containing food items are flushed with nitrogen. Why?

Answer:

Because oils and fatty substances come in contact with the air, they become oxidized and give off a bad smell. Along with their smell, their taste also changes. For this reason, oily and fatty foods are flushed with nitrogen so that they do not spoil. Nitrogen, being a non-reactive gas, prevents the unwanted oxidation of the food.
