In today's era of hurry and ,bustle no one has time to cook food and either they depend on ready-made food from restaurants or on pre-cooked food from large scale food manufacturers and this food manufactured had then stored and transported to sellers ,so there is a large gap between production and consumption of food and to keep food in good shape and taste in process of manufacturing number of additive added as preservatives.Now the question arises,Is these preservatives are safe! I am not a hundred per cent sure about the safety of those ingredients but going to discuss them in the essay.
