Environmental Impact Assessment of Plant-Based Food Additives

Plant-based food additives, mostly derived from agricultural products, have become a substitute for synthetic additives in food industry in recent years. Thy are safer, more metabolic compatible and more effective in antioxidant and antimicrobial effects. However, the environmental performance of these additives remains insufficiently quantified. This study employs Life Cycle Assessment (LCA) to illustrate their ecological impacts across production, processing, and application. Especially pay attention to green extraction processes such as supercritical CO₂ extraction, ultrasound-assisted extraction, and valorization of agricultural by-products. Results indicate that plant-based additives generally achieve lower carbon footprints and reduced ecotoxicity compared with synthetic food additives, while supporting circular economy pathways through the renewable recourses. Nevertheless, there are several challenges hinder industrial-scale adoption, high production costs and the lack of unified safety and quality standards. Addressing these barriers requires a combination of technological innovation, standard-setting, and policy incentives such as carbon pricing and green certification. By integrating environmental, industrial, and societal perspectives, this research highlights the potential of plant-based food additives to advance sustainable food systems and contribute to global climate and health goals.
