Video 3 Biodegradable and Edible Film Kemasan Biodegradable dan Edible | EDIBLE FILM

Summary

This video discusses edible packaging, which is made from edible materials designed to provide a sustainable alternative to traditional packaging. The speaker explains the difference between edible films and coatings, their applications, and the materials used, such as polysaccharides, proteins, and lipids. The focus is on how these materials can improve food preservation, with the added benefit of being biodegradable and environmentally friendly. Techniques for creating these films and coatings, as well as their advantages, such as enhancing product shelf life and providing antimicrobial properties, are also covered. The video highlights the role of innovation in packaging, including the use of microencapsulation and the combination of different biopolymers for improved performance.

Takeaways

• 😀 Edible packaging refers to materials made from substances that are consumable and can be used as thin films or coatings for food products.
• 😀 Edible films are typically thicker than edible coatings, with films being easier to remove while coatings tend to be more integrated into the food product.
• 😀 The thickness of edible films generally ranges from 0.03 mm to 0.25 mm, whereas coatings are much thinner, sometimes as thin as a few nanometers.
• 😀 The two types of edible packaging, film and coating, serve to protect food, prevent contamination, and can even function as barrier layers against moisture, oxygen, and fats.
• 😀 Edible films and coatings can be created from a variety of materials, including polysaccharides, proteins, and lipids, each with unique properties like water sensitivity or gas permeability.
• 😀 In terms of application, edible films are typically formed into sheets before being applied, whereas coatings are formed directly on the surface of the food.
• 😀 One significant advantage of edible packaging is that it can act as a carrier for active substances such as antioxidants or preservatives without directly adding them to the food itself.
• 😀 The development of active edible films is a growing area, with potential applications for enhancing food preservation and improving food safety by incorporating antimicrobial agents.
• 😀 The ideal edible packaging should be biodegradable, environmentally friendly, and provide protection against microbial growth, contributing to the product's longevity.
• 😀 Challenges in edible film and coating formulation include balancing moisture permeability and mechanical strength, which can be addressed by combining different materials in composite formulations.

Q & A

What is an edible packaging material?

An edible packaging material is made from substances that can be eaten, serving as a protective film or coating. It can be used to package food products and is designed to enhance food preservation while also being safe for consumption.

What is the difference between edible films and coatings?

Edible films are thin layers that can be separated from the food product, while coatings are thin layers that bond directly with the food, often used to protect and enhance food quality. Coatings are usually harder to remove and are often consumed with the product, while films can be peeled off.

What are the common materials used to create edible packaging?

Edible packaging is often made from hydrocolloids, proteins, and polysaccharides. These materials are either derived from natural sources like fruits or plants or synthesized for their edible and biodegradable properties.

How are edible films and coatings applied to food products?

Edible films are generally applied by casting, where the material is formed into a thin sheet and then placed on the food. Coatings, on the other hand, are usually applied by dipping, spraying, or brushing, forming a layer that adheres directly to the food's surface.

What is the purpose of edible films and coatings in food packaging?

The main purpose of edible films and coatings is to enhance the shelf life of food by acting as a barrier to moisture, oxygen, and other environmental factors. They can also provide additional nutrients, antioxidants, and antimicrobial properties to the food.

What are the advantages of edible packaging materials over traditional plastic packaging?

Edible packaging materials are more environmentally friendly as they are biodegradable and compostable. They also reduce the reliance on plastic, offering a more sustainable option while also providing additional benefits like enhancing food preservation.

What challenges do edible films and coatings face in the food packaging industry?

Challenges include maintaining the material’s strength and barrier properties under various conditions, such as humidity and temperature fluctuations. There is also the challenge of scaling production processes to meet the demands of the food industry while keeping costs competitive.

What is microencapsulation, and how is it used in edible packaging?

Microencapsulation involves enclosing active ingredients, such as preservatives or nutrients, within a protective layer. In edible packaging, this process is used to deliver controlled-release ingredients that can improve food preservation or enhance nutritional value.

What role do polysaccharides play in edible films and coatings?

Polysaccharides, such as starch, pectin, and cellulose, are key ingredients in edible films and coatings due to their ability to form films and provide structural integrity. They also offer moisture retention and barrier properties, essential for food preservation.

How do edible coatings impact the texture and appearance of food products?

Edible coatings can improve the texture by providing a protective layer that maintains moisture balance. They can also enhance the visual appeal of food by giving it a glossy finish, though improper formulation may cause the film to appear cloudy or uneven.
