The invention discloses a kind of edible polysaccharide antimicrobial compound films and preparation method thereof.Contain in composite membrane component: chitosan, pulullan polysaccharide, epsilon-polylysine, glycerol.Preparation step is as follows: chitosan being dissolved in acetic acid solution, addition pulullan polysaccharide configures film based sols, adds natural bacteriostatic agent epsilon-polylysine, glycerol is eventually adding as plasticizer, is stirred evenly, degassing is stood, mixing film liquid is pipetted as in the mold of acrylic material, drying and forming-film.The invention has the advantages that: the composite antibacterial film smooth in appearance of this method preparation is smooth, and light transmittance is preferable, has good mechanical performance and bacteriostasis property, degradable, can effectively inhibit the growth of peeled shrimp surface microorganism. |
