2results about "Meat/fish preservation using solids" patented technology

The invention belongs to the technical field of food fresh-keeping materials, and particularly relates to an aerogel type composite fresh-keeping pad as well as a preparation method and application thereof. The preparation method of the aerogel type composite fresh-keeping pad comprises the following steps: S1, mixing polyethylene glycol, oxalic acid and polyacrylic acid, and stirring at 70-80 DEG C to obtain a eutectic solvent; the method comprises the following steps: mixing a biomass raw material with a deep eutectic solvent, extracting, and filtering to obtain solid residues; s2, mixing the obtained solid residues with water, performing high-pressure homogenization treatment, mixing the obtained cellulose-containing suspension with a gelatin solution and a cross-linking agent, pouring the obtained mixed solution into a forming mold, performing freeze-drying treatment, and taking out to obtain the aerogel type composite fresh-keeping pad. The aerogel type composite fresh-keeping pad prepared by the method disclosed by the invention has good mechanical property, water absorption and antibacterial activity, and shows an excellent fresh-keeping effect in fresh-keeping of fish slices.
