涂层技术在番茄保鲜中的研究与应用OA

Tomato is nutritious.delicious,and widely favored by consumers.However,after being picked,due to its fruit characteristics and vigorous metabolic activities,tomato is highly susceptible to microbial infection,mechanical damage,and environmental factors during storage and circulation,leading to fruit decay,quanlity deterioration,and substantial eco-nomic losses.Therefore,there is urgent need to develop efficient,safe and green preservation technologies for preserva-tion tomato storage.In recent years,with growing public awareness of food safety and environmental protection,green technologies such as biological preservation and coating preservation have attracted increasing attention.Among these,coating preservation technology,which utilizes edible materials to form a protective film on the fruit surface,can effec-tively regulate moisture loss,respiration rate,and microbial growth,thereby delaying quality deterioration,and presents an environmentally friendly preservation approach.This paper systematically reviews the key factors influencing tomato preservation,with a focus on the classification and mechanisms of coating technologies,including edible coatings,com-pound coatings,composite coatings,and functional coatings(microbial coating,plant extract coatings).The existing chal-lenges and future trends are also discussed,aiming to provide a theoretical basis for innovation in tomato preservation technologies.
