DEMO DAY innowacji 4.0

A biopolymer bilayer film based on furcelleran, CMC, gelatin hydrolysate and bilberry extract and biopolymer trays based on tea grounds have been obtained in this project. The obtained films show high antioxidant and antimicrobial activity. Additionally, bilayer films enriched with bilberry extract and biopolymer trays were used as packaging materials for the salmon storage. The results obtained indicated an improvement in the quality of fish during storage compared with salmon stored in synthetic films. The presented films and trays are biodegradable within a period of four weeks. This technology offers a promising alternative to conventional packaging as its use can improve food safety by inhibiting pathogenic bacteria or oxidation reactions while reducing the environmental impact of wasted food and packaging waste. The use of active films can extend the shelf life of stored products and maintain the 'clean label' trend. Since the packaging is made of waste materials, the cost of the technology for the entrepreneur will be low.
