The invention discloses a fresh-keeping film of sodium starch octenyl succinate and a preparation method thereof, belonging to the technical field of packaging materials. The invention provides a sodium starch octenyl succinate-based fresh-keeping film. The fresh-keeping film is prepared from the following raw materials: 0.05% to 1% of antimicrobial peptides, 0.002% to 0.12% of nano-titanium dioxide, and 1% of sodium starch octenyl succinate. ~6%, gorse powder 1%~6%, sesame flower powder 1%~6%, roselle powder 1%~6%, plasticizer 0%~30%, purified water 40%~60%. The invention adopts natural non-toxicity, wide raw material sources, simple preparation process, low cost and high synthesis efficiency, the prepared edible film has good mechanical properties, can effectively inhibit Gram-negative bacteria and Gram-positive bacteria, and can effectively Therefore, when food is packaged with the fresh-keeping film provided by the present invention, bacteria and anti-oxidation can be effectively inhibited, thereby prolonging the preservation time of food. |
