A review of life cycle assessment (LCA) on some food products

Life cycle assessment (LCA) is a tool that can be used to evaluate the environmental load of a product, process, or activity throughout its life cycle. Today’s LCA users are a mixture of individuals with skills in different disciplines who want to evaluate their products, processes, or activities in a life cycle context. This study attempts to present some of the LCA studies on agricultural and industrial food products, recent advances in LCA and their application on food products. The reviewed literatures indicate that agricultural production is the hotspot in the life cycle of food products and LCA can assist to identify more sustainable options. Due to the recent development of LCA methodologies and dissemination programs by international and local bodies, use of LCA is rapidly increasing in agricultural and industrial food products. A network of information sharing and exchange of experience has expedited the LCA development process. The literatures also suggest that LCA coupled with other approaches provides much more reliable and comprehensive information to environmentally conscious policy makers, producers, and consumers in selecting sustainable products and production processes. Although LCA methodologies have been improved, further international standardization would broaden its practical applications, improve the food security and reduce human health risk.
