Zusammenfassung:	The invention discloses polysaccharide-based antibacterial liquid as well as a preparation method and application thereof. The preparation method of the polysaccharide-based antibacterial liquid comprises the following steps: firstly, preparing an antibacterial component, a chitosan solution, a carboxymethyl dextran solution and a polyvinyl alcohol solution; mixing the chitosan solution, the carboxymethyl dextran solution and the polyvinyl alcohol solution, performing ultrasonic treatment, adding the antibacterial component, and mixing; the antibacterial component comprises at least one of citral and oxidized dextran cross-linked antibacterial microsphere dispersion liquid for encapsulating the citral. And further preparing an antibacterial composite coating or an antibacterial film material by using the antibacterial liquid. The prepared antibacterial film has high transparency, proper water vapor barrier property and good mechanical property, the antibacterial coating is directly coated on the surfaces of f
