Introduction

In recent years, the demand for sustainable and eco-friendly packaging solutions has increased significantly. The use of conventional plastics has been linked to environmental pollution and health concerns. As a result, researchers have been exploring alternative packaging materials, including edible films. In this study, we aim to develop edible films from a mixture of tapioca flour, chitosan, glycerin, and red dragon fruit extract as a packaging solution for cow sausages.

Materials and Methods

The edible films were prepared by mixing tapioca flour, chitosan, and glycerin as a plastic. The mixture was then printed on an acrylic plate and dried in an oven at 40°C for two days. The resulting film was analyzed for its physical characteristics, including thickness, tensile force, and elongation. The morphology of the film was examined using Electron Microscopy (SEM) scanning, and the chemical composition was analyzed using Fourier Transform Infrared (FTIR) spectroscopy.

Physical Characteristics and Analysis

The edible film produced had a thickness of 0.236 mm, a tensile force of 0.0498 kgf/mm², and an elongation of 14.54%. The morphology of the film was flat, as observed using SEM scanning. The FTIR analysis showed a spectrum at 3241 cm⁻¹ - 3274 cm⁻¹, indicating the repetition of -OH and/or -nh groups, as well as at 2923 cm⁻¹ - 2925 cm⁻¹, which is the repetition of the amide group C = O.

Antibacterial Activity

The antibacterial activity of the edible film was tested using the Kirby Bauer method. The results showed that the edible film had a negative effect on the bacterium Staphylococcus aureus and Escherichia coli. The clear zone produced in two samples with a concentration of 0.023 cfu/ml indicated the antibacterial activity of the film. Further analysis using the Standard Plate Count method showed that the number of bacterial colonies in sausages wrapped in edible films was less than sausages that were not wrapped.

Conclusion and Implications

The development of edible films from a mixture of natural ingredients such as tapioca flour, chitosan, glycerin, and red dragon fruit extract offers innovative solutions in food packaging, especially for cow sausages. The edible film not only functions as a package but also helps in maintaining the safety and quality of food products. The use of natural ingredients is also in line with the trends of consumers who are increasingly concerned with health and sustainability, making it an attractive choice for food producers in the future.

Future Directions

Edible films have great potential to be applied in the food industry and can be an environmentally friendly alternative compared to the use of conventional plastics. With further research, we can explore more potential uses of edible films in various types of food, providing more benefits for public health and the environment.

Benefits of Edible Films

Edible films offer several benefits, including:

Sustainable packaging: Edible films are biodegradable and compostable, reducing the environmental impact of packaging waste.
Food safety: Edible films can help maintain the safety and quality of food products by preventing the growth of bacteria and other microorganisms.
Health benefits: Edible films can be made from natural ingredients that are rich in nutrients and antioxidants, providing health benefits to consumers.
Cost-effective: Edible films can be a cost-effective alternative to traditional packaging materials, reducing the financial burden on food producers.

Limitations and Challenges

While edible films offer several benefits, there are also limitations and challenges associated with their use. These include:

Scalability: Edible films are still in the early stages of development, and scaling up production to meet commercial demands can be a challenge.
Cost: While edible films can be cost-effective in the long run, the initial investment in production and research can be high.
Shelf life: Edible films have a limited shelf life, which can affect their usability and effectiveness.

Conclusion

In conclusion, edible films made from a mixture of tapioca flour, chitosan, glycerin, and red dragon fruit extract offer innovative solutions in food packaging, especially for cow sausages. The edible film not only functions as a package but also helps in maintaining the safety and quality of food products. With further research and development, edible films can become a sustainable and eco-friendly alternative to traditional packaging materials.

Q: What are edible films?

A: Edible films are thin, flexible sheets made from edible materials, such as natural polymers, proteins, and lipids. They are designed to be consumed along with the food they package, providing a sustainable and eco-friendly alternative to traditional packaging materials.

Q: What are the benefits of edible films?

A: Edible films offer several benefits, including sustainable packaging, food safety, health benefits, and cost-effectiveness. They can also help reduce packaging waste, prevent the growth of bacteria and other microorganisms, and provide a natural and nutritious coating for food products.

Q: What are the common ingredients used to make edible films?

A: The common ingredients used to make edible films include natural polymers, such as starch, cellulose, and chitosan; proteins, such as whey, soy, and egg; and lipids, such as fatty acids and triglycerides. Other ingredients, such as glycerin, water, and flavorings, may also be added to enhance the film's properties and appearance.

Q: How are edible films made?

A: Edible films are typically made by mixing the ingredients together and then casting or extruding the mixture into a thin sheet. The sheet is then dried and processed to create a flexible and durable film.

Q: What are the applications of edible films?

A: Edible films have a wide range of applications, including food packaging, pharmaceutical packaging, and medical devices. They can be used to package a variety of food products, such as meat, dairy, fruits, and vegetables, as well as to create edible cutlery, cups, and other disposable items.

Q: Are edible films safe to eat?

A: Yes, edible films are safe to eat. They are made from edible ingredients and are designed to be consumed along with the food they package. However, it's essential to ensure that the film is made from high-quality ingredients and is produced in a clean and sanitary environment to prevent contamination.

Q: Can edible films be customized to meet specific needs?

A: Yes, edible films can be customized to meet specific needs. The ingredients, thickness, and properties of the film can be adjusted to suit the requirements of the food product or application.

Q: What are the challenges associated with edible films?

A: Some of the challenges associated with edible films include scalability, cost, and shelf life. Edible films are still in the early stages of development, and scaling up production to meet commercial demands can be a challenge. Additionally, the cost of production and research can be high, and the shelf life of edible films may be limited.

Q: What is the future of edible films?

A: The future of edible films is promising, with many companies and researchers working to develop new and innovative applications for these sustainable and eco-friendly packaging materials. As the demand for sustainable packaging continues to grow, edible films are likely to become an increasingly important part of the packaging industry.

Q: How can I get involved in the development of edible films?

A: If you're interested in getting involved in the development of edible films, there are several ways to do so.
