Preparation of Nanocomposite Film and Its Application in Fruit and Vegetable Preservation
Fruits and vegetables are susceptible to their own physiological metabolism,changes in external environmental conditions,pathogenic bacteria and mechanical damage during postharvest storage and transportation,resulting in a large number of their decay and deterioration.Therefore,based on the deterioration mechanism of fruits and vegetables,the development of nanocomposite films with good freshness preservation performance,green environmental protection,safety and easy degradation is a hotspot of current research.The article mainly introduces the preparation method of nanocomposite film and its performance characteristics,analyzes the advantages of nanocomposite film in mechanical,gas barrier,antibacterial,degradability,etc.,and elucidates the latest research progress of nano-metal composite film,nano-metal oxide composite film,and natural polymer nano-fiber composite film,which are widely used in the field of preservation of fruits and vegetables and look forward to the prospect of their development,with a view to It also provides reference for the development and industrialization of nanocomposite films in the field of fruit and vegetable preservation.
