食品供应链使用大量化石燃料和其他不可再生资源以及水和土地，对我们的环境产生重大影响。食品供应链也是一个复杂的系统，因此对其进行评估需要对整个系统进行研究，从初级生产到最终的食品浪费解决方案。本文从方法论的角度探讨了目前已发表的食品供应链生命周期评估研究的现状及其质量和与现有标准的一致性。特别是，我们遵循国际标准化组织的框架，并考虑了标准的要求，强调目标和范围，库存，生命周期影响评估和解释。我们调查了49篇研究和评论论文，来源于Web of Science。此外，我们还进行了内容分析，确定了研究领域和现有的研究趋势。研究结果确定了在目标和范围以及清单和生命周期影响评估方面可能的改进，以提高研究的一致性和可靠性。这些研究反过来又会影响透明和以可持续性为导向的决策过程，这在公司、利益相关者、国家和全球各级都至关重要。概念图揭示了最主要的研究方向，即生产、使用、系统和包装。缺少的是社会经济影响的作用，因为食品生命周期包括生产或报废过程中的社会和经济功能以及循环经济选择。
Food supply chains have substantial impacts on our environment, using large amounts of fossil fuel and other non-renewable resources, as well as water and land. Food supply chains are also complex systems, and their evaluation thus requires a study of the entire system, from primary production to end-of-life food-waste solutions. This paper examines the current state-of-the-art of the published food supply chains Life Cycle Assessment studies and their quality and coherency with the existing standards from the methodological perspective. In particular, we have followed the framework of the International Organization for Standardization, and considered the standard’s requirements, emphasising goal and scope, inventory, life cycle impact assessment and interpretation. We have surveyed forty-nine research and review papers, sourced from the Web of Science. Additionally, we have carried out a content analysis, identifying research areas and existing research trends. The results identified possible improvements in terms of goals and scope, as well as inventory and life cycle impact assessment, to increase the consistency and reliability of studies. These studies, in turn, affect a transparent and sustainability-oriented decision-making process, which is essential at various levels – company, stakeholders, national and global. Concept maps reveal the most dominant research directions, which are production, use, system and packaging. Missing is a role of socio-economic effects, as food life-cycles include societal and economic functions as well as circular economy options, during production or end-of-life processes.
