Chinese Food Life Cycle Assessment Database
收藏资源简介:
In the Chinese Food Life Cycle Assessment Database (CFLCAD), Greenhouse Gas Emissions (GHGE) for 80 food items, Water Use (WU) for 93 food items and Land Use (LU) for 50 food items are collected through a literature review. The CFLCAD applies conversion factors for the edible portion of food, food loss ratio and processing, storage, packaging, transportation, and food preparation stages to estimate the environmental footprints of food from production to consumption. Similar food groups and recipes are used to match those food items without LCA value in the Chinese food composition table, resulting in a total of 17 food groups in the database.
在《中国食品生命周期评估数据库》(CFLCAD)中,通过对80种食品的温室气体排放(GHGE)、93种食品的用水量(WU)以及50种食品的土地使用(LU)进行文献综述,收集了相关数据。CFLCAD应用了食品可食用部分、食品损耗比率以及加工、储存、包装、运输和食品准备阶段等转换系数,以估算从生产到消费阶段食品的环境足迹。通过使用类似食品类别和食谱,以匹配中国食品成分表中缺乏生命周期评估值(LCA)的食品项目,从而在数据库中形成了共计17个食品类别。
