Potential And Application Of Bacterial Nanocellulose From Symbiotic Culture Of Bacteria And Yeast For Active Food Packaging
Potential and Application of Bacterial Nanocellulose from Symbiotic Culture of Bacteria and Yeast for Active Food Packaging
Introduction
The world is facing a significant challenge in the form of plastic waste, which is not only harming the environment but also posing a threat to human health. The use of plastic in food packaging is a major contributor to this problem, and it is essential to find alternative and sustainable solutions. One such innovation is the use of bacterial nanocellulose (BNC) produced from a symbiotic culture of bacteria and yeast. BNC has shown great potential in replacing plastic-based packaging, and in this study, we will explore its application in active food packaging.
Advances in Food Packaging Technology
In recent years, there has been a significant shift towards sustainable and environmentally friendly food packaging solutions. The use of plastic-based packaging has been widely criticized due to its negative impact on the environment. As a result, researchers have been exploring alternative materials that can replace plastic while maintaining the quality and safety of food. BNC, produced through an environmentally friendly and low-cost approach, is one such material that has shown great promise.
Bacterial Nanocellulose (BNC)
BNC is a biodegradable and non-toxic material that is produced through the fermentation of bacterial and yeast symbiotic culture. It has a unique structure that makes it an excellent material for food packaging. BNC is not only biodegradable but also has antimicrobial properties, which make it an ideal material for active food packaging. However, BNC does not have antimicrobial properties naturally, and it requires the addition of other materials to enhance its properties.
Symbiotic Inoculum Fermentation for Bacterial Cellulose (SIFB)
The SIFB method is a novel approach that has been developed to produce BNC. This method involves the use of a symbiotic culture of bacteria and yeast, which produces BNC through fermentation. The SIFB method has been proven to be successful in producing high-quality BNC, and it has been used in this study to produce BNC-Chitosan films.
Properties of BNC-Chitosan Films
The properties of BNC-Chitosan films were analyzed using FTIR and SEM, and the results showed that the merging of BNC and Chitosan took place well. The tensile strength of the films was found to be 16,7763 MPa, and the water vapor transmission rate (WVTR) was 0.1928 kg S m³. These values indicate that the packaging is quite strong and effective in preventing humidity from entering the packaging.
Antibacterial and Antioxidant Activity
The antibacterial activity of BNC-Chitosan films was tested against the bacterium Escherichia coli and Staphylococcus aureus, and the results showed a significant zone of resistance. The antioxidant activity of the films was also tested, and the results showed a strong ICS value of 98,0187 ppm. This indicates that the packaging is not only able to extend the shelf life of food but also maintain its quality and safety.
Shelf Life Test
A shelf life test was conducted on apples, eggplants, and chicken meat wrapped in active packaging BNC-Chitosan. The results showed a good storage time, which was 21 days for apples, 6 days for eggplant, and 24 hours for chicken meat. When compared with food ingredients wrapped in plastic or only using BNC, it appears that the BNC-Chitosan packaging succeeded in slowing down the decay process.
Conclusion
This study has shown that bacterial nanocellulose from the culture of bacterial symbiotic and yeast, which is combined with chitosan, has great potential as an environmentally friendly active food packaging. With the ability to extend shelf life and maintain food quality, this innovation can be an effective solution in overcoming pollution problems due to the use of plastic and improving food safety. By utilizing this technology, we not only protect the environment but also improve the quality of life of the community through the provision of safer and durable food.
Future Directions
Further research is needed to explore the potential of BNC-Chitosan films in various food packaging applications. The scalability and cost-effectiveness of the SIFB method need to be improved to make it a viable alternative to traditional food packaging materials. Additionally, the long-term effects of BNC-Chitosan films on food quality and safety need to be investigated to ensure their safe use in food packaging.
