| titleOfInvention | A kind of preparation method of cellulose/chitosan-based nanometer fresh-keeping drug-loaded sponge |
| abstract | The invention relates to a preparation method of a cellulose/chitosan-based nanometer fresh-keeping drug-carrying sponge, and belongs to the technical field of food packaging materials. The present invention uses sodium carboxymethyl cellulose and chitosan as the main base materials. The steps of the preparation method include: firstly dissolving sodium carboxymethylcellulose and chitosan in distilled water and acetic acid solution according to a certain mass ratio, then blending the two solutions, adjusting the pH value to 1.0 with hydrochloric acid, and then mixing the two solutions. Add antibacterial factor nano-titanium dioxide, ethylene adsorption factor bentonite and plasticizer glycerin, stir well, let it stand for defoaming, and finally pour it into a mold, and vacuum freeze-dry to form a sponge product. The product is non-toxic, harmless, biodegradable, and environmentally friendly. The product has added nano-antibacterial factors and ethylene adsorption factors, which not only has the basic mechanical buffering performance of filling sponges, but also has excellent antibacterial and fresh-keeping effects. . |
