Beschreibung
Zusammenfassung:	The invention discloses a cellulose-based membrane with photodynamic bacteriostatic activity as well as preparation and application thereof. The preparation method comprises the following steps: preparing a beta-cyclodextrin/curcumin embedding substance by adopting a coprecipitation method, then preparing a supersaturated solution of the beta-cyclodextrin/curcumin embedding substance, taking supernate of the supersaturated solution, adding the supernate intoan oxidized cellulose solution, and uniformly mixing, casting the mixed solution in a mold, and drying to obtain the cellulose-based film with photodynamic antibacterial activity. The cellulose-based antibacterial food packaging film is a cellulose film dispersed with cyclodextrin particles, and curcumin is wrapped in the cyclodextrin particles. The cellulose-based film with the photodynamic antibacterial activity is good in food safety, low in cost and environmentally friendly, and a brand new thought is provided for antibacterial treatment of food by com
