水产预制菜碳足迹测算与减排机制分析——基于佛跳墙LCA研究OA
Carbon Footprint Assessment and Emission Reduction Mechanism Analysis for Aquatic Pre-prepared Meals:An LCA Study of Buddha Jumping Over the Wall
为解决水产预制菜产业规模化进程中冷链系统能源高消耗与生态可持续性矛盾,采用生命周期评价法(LCA)构建"养殖-加工-冷链运输-仓储销售-消费"全链条分析框架,以佛跳墙预制菜为对象核算碳足迹并揭示冷链依赖性供应链的碳排放特征.结果表明:水产预制菜供应链碳排放呈现"双峰发布",加工(43.25％)和冷链运输(24.58％)为核心排放源,仓储销售(25.19 kg,14.24％)与养殖(24.65 kg,13.94％)次之,其他环节占 3.15％.相较肉类食品供应链,其全链碳排放显著降低 3％,消费端碳排放则呈现指数增长趋势,特别是当冷藏时间从 1 d延长至35 d时,其碳排放占比由0.99％激增至30.91％;且家用冰箱功率越高,碳排放增长系数敏感性越低.基于此,提出"标准化-信息化-生态化"为核心的碳减排机制、为食品产业绿色转型提供了技术支撑.
To address the conflict between high energy consumption in cold chain systems and ecological sustainability during the scaling of China's aquatic Pre-prepared meals industry,this study employs Life Cycle Assessment(LCA)to establish a comprehensive"Farming-Processing-Cold Chain Transportation-Storage&Retail-Consumption"analytical framework.Using Buddha Jumping Over the Wall Pre-prepared meals as a case study,we quantify its carbon footprint and reveal emission patterns in cold chain-dependent supply chains.Results indicate a bimodal distribution of carbon emissions:processing(43.25％)and cold chain transportation(24.58％)constitute the core emission sources,followed by storage&retail(25.19 kg,14.24％)and farming(24.65 kg,13.94％),with other stages contributing 3.15％.Notably,the aquatic premade supply chain demonstrates a 3％reduction in total emissions compared to meat supply chains,while consumption-stage emissions exhibit exponential growth – particularly when cold storage extends from 1 to 35 days,where its emission share surges dramatically from 0.99％to 30.91％.Higher household refrigerator power correlates with lower sensitivity in emission growth coefficients.Consequently,we propose a carbon reduction mechanism centered on Standardization-Informatization-Ecologization,providing critical technical support for the food industry's green transition.
