Several initiatives have been proposed to address food waste and loss issues and support stakeholders throughout the food chain. However, the literature still lacks a review paper that compiles methods, practices, and solutions to reduce food waste and loss. With the goal of filling this gap, this paper aims to compile and gather food waste and loss prevention and minimization methods to support decision-makers and other stakeholders along the food chain. Through a systematic literature review, we have outlined research findings and empirical studies on food waste and loss prevention and minimization methods previously published, studied, implemented, and discussed in the scientific literature worldwide. A sample of 84 articles was analyzed. As a result, this study provides a bibliometric analysis of the sample and a classification of the prevention and minimization methods found in the articles in 10 fields established by the authors. A coverage analysis of empirical studies was also performed, cross-checking the data with the type of food extracted from the case studies application. Lastly, suggestions of future research extracted from the articles were compiled into a research agenda to indicate trends and support academics, researchers, practitioners, and other stakeholders involved in the food chain to develop and study practices to minimize and prevent food waste and loss. The main contribution of this study is an inventory of the theoretical and practical methods of prevention and minimization of food waste and loss found in the literature, grouping them according to their similarities, to support stakeholders improving actions to reduce food waste in cities, farms, retail, and other sustainable ecosystems.
