Study Notes
Investigation of Antibacterial Activity of Chitosan
- Chitosan-based biodegradable functional films have been developed for food packaging applications
- Chitosan-based UV barrier composite films have been reinforced with cellulose nanocrystals for sustainable packaging
- Halochromic and antioxidant capacity of smart films of chitosan/chitin nanocrystals with curcuma oil and anthocyanins have been investigated
Anthocyanins and their Applications
- Anthocyanins are a type of polyphenol, a subgroup of flavonoids, with over 600 identified types
- The six most common anthocyanidins are cyanidin, pelargonidin, delphinidin, petunidin, peonidin, and malvidin
- Anthocyanins can be found in various chemical structures and colors depending on the pH of the solution
- Cyanidin-3-glucoside is one of the most common anthocyanins in black rice, black bean, and many berries
- Anthocyanins have been used in the development of smart packaging films that change color in response to changes in pH
Smart Packaging Films
- Smart packaging films have been developed to monitor food freshness and quality
- These films are based on biodegradable materials such as chitosan, starch, and polyvinyl alcohol
- Anthocyanin-rich extracts have been incorporated into smart packaging films to create pH-sensitive indicators
- The films change color in response to changes in pH, indicating the freshness and quality of the packaged food
Biodegradable Materials for Food Packaging
- Biodegradable materials such as chitosan, starch, and polyvinyl alcohol have been used in food packaging applications
- These materials are more environmentally friendly than synthetic materials
- Biodegradable materials have been reinforced with nanomaterials such as cellulose nanocrystals and nanoparticles to improve their properties
Food Quality and Safety Monitoring
- Smart packaging films have been used to monitor food quality and safety
- The films provide a visible indication of food freshness and quality, allowing consumers to make informed decisions
- The use of biodegradable materials and natural substances such as anthocyanins has been driven by consumer demand for more environmentally friendly and sustainable packaging solutions
