Food waste research focuses on understanding the causes and impacts of food waste in our society. This includes studying the amount of food wasted at different stages of the food supply chain, such as production, distribution, and consumption. Researchers also explore ways to reduce food waste through better packaging, storage, transportation, and consumer behavior. Additionally, they investigate the environmental, social, and economic implications of food waste, and develop strategies to address this global problem. Overall, food waste research aims to promote more sustainable and efficient practices in the food industry and reduce the negative effects of wasted food on the environment and society.
