Food is the most indispensable part of our human life. Grains, Pulses, Fruits, Vegetables, Oils, etc., contain more amount of nutrients. But nowadays because our busy schedules, we consume food based on our comfort. We could not analyze if the food is either good or harmful to our health. A food with insufficient nutritional value is referred to as junk food. According to the recent studies, children are almost addicted to this junk food items because of cartoons and animations advertisement for unhealthy food habits. They conceive a curiosity among the children. These food items forge various diseases in their body both mentally and physically. Parents cannot steer them to avoid this processed food. These foods affect the children's healthy food habits. To isolate the desirable alternative in multicriteria decision-making problems, a novel accuracy function is introduced. Based on the novel accuracy function, a multicriteria fuzzy-decision making method is entrenched in which criterion values for alternatives are interval-valued intuitionistic fuzzy sets.

Grains have enacted a supreme role in human history and grain agriculture. Cereal grains are the worlds most substantial origin of food energy. The loss of grains can occur in three stages which are Pre-harvest, harvest and Post-harvest stages. Post-harvest losses take place during the time of harvest and the stage of human consumption. The losses can occur at the process of transportation, processing, storage and also by insects attack. In many developing countries the post-harvest losses are normal. In grain storage, several methods are being used to detect insects. But methods which are efficient and also time saving are very much needed. So, researchers have advanced many detection techniques to find insects in the stored grains. The weighted correlation coefficient using entropy weights give more enlightenment to solve many prevailing problem in real life. The encouragement of this research work is to interpret the sellers perspectives of insect detection technique for stored grains.
