AI Technical Summary
Fresh aquatic products and meat products are susceptible to microbial infection and enzymatic reactions during low-temperature storage. Traditional absorbent materials cannot effectively inhibit the proliferation of microorganisms in the exudate, and lack antibacterial and antioxidant properties, resulting in quality deterioration.
Polylactic acid-reinforced bacterial cellulose-based aerogel with step-by-step sustained-release performance was used. A mixed aerogel liquid was prepared by mixing bacterial cellulose dispersion, a cross-linking agent and hollow mesoporous silica carrying a biological preservative. The mixed aerogel liquid was then modified by polylactic acid impregnation to form an aerogel with strong water absorption and long-lasting antibacterial and antioxidant properties.
It can effectively absorb the exudate and water vapor during the storage and transportation of fresh food, inhibit the reproduction of microorganisms, maintain food quality, and extend the shelf life. It also has a stable structure and good biocompatibility, making it suitable for industrial production.
