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.
已经提出了几项举措来解决食物浪费和损失问题，并为整个食物链中的利益相关者提供支持。然而，文献中仍然缺乏一篇综述论文，来汇总减少食物浪费和损失的方法、实践和解决方案。本文旨在填补这一空白，编译并收集食物浪费和损失预防和最小化的方法，以支持食物链上的决策者和其他利益相关者。通过系统的文献综述，我们概述了全球科学界之前发表的、研究过的、实施过的和讨论过的关于食物浪费和损失预防和最小化方法的研究结果和实证研究。对 84 篇文章进行了分析。因此，本研究对样本进行了文献计量分析，并按照作者确定的 10 个领域对文章中发现的预防和最小化方法进行了分类。还对实证研究进行了覆盖分析，通过案例研究应用中提取的食物类型对数据进行交叉检查。最后，从文章中提取了未来研究的建议，汇编成一个研究议程，以指示趋势并为参与食物链的学者、研究人员、从业者和其他利益相关者提供支持，以开发和研究减少食物浪费和损失的实践。本研究的主要贡献是在文献中发现的食物浪费和损失预防和最小化的理论和实践方法的清单，并根据它们的相似性对其进行分组，以支持利益相关者在城市、农场、零售和其他可持续生态系统中采取减少食物浪费的行动。
