Abstract: Usually,foods are packaged with some preservative and such chemicals in the form of organic and inorganic preservative are being used for packaging different types of food.But in India, companies are using inorganic preservatives mostly and these inorganic preservatives are very harmful to human’s body. In this paper, a new model is developed to reduce the quantity of chemicals in packaged food. This problem is modelledby fuzzy inference and is also combined with graphtheory methodology to provide a unique and defective solution.The sideeffectofeachpackagedfoodistobemeasuredusinga fuzzy interference system. A real-life application on Haringhatachicken has been presented in this paper by using fuzzy inference logic and graph theory. At last, a comparison of the result hasbeendemonstrated to justify the solution.
