Here is what you need to know about this creative solution that reshapes the future of the food and packaging industries.

What is Edible Packaging?

Edible packaging is precisely what it sounds like—packaging that can be safely consumed along with the food it encloses. It can take various forms, from coatings and films to wrappers and containers, all designed to serve as a protective shield for food while remaining entirely edible.

The best part?

This innovative approach transforms packaging from a disposable item into an integral part of the food supply chain.

While conventional packaging materials often contribute to environmental issues and waste, edible packaging eliminates the need for single-use plastics and other non-recyclable materials.

This directly addresses the concerns related to packaging waste and its ecological impact.

Edible Packaging Materials and Their Properties

There are two distinct edible food packaging materials: films and coatings.

But what is the difference between the two?

  • Edible films: Edible films are thin, flexible sheets made from biopolymers, such as polysaccharides (like starch and gums) or proteins (such as gelatin and gluten). These films are created separately and then applied to food products. They serve as protective layers, shielding the food from external factors. However, they are sensitive to moisture and are not suitable for application to foods susceptible to rapid food deterioration.
  • Edible coatings: Edible coatings, on the other hand, are protective layers directly formed and applied to food items. They can be superficial coatings or layers between different compartments within the same food product. Edible coatings also utilize biopolymers like polysaccharides, proteins, and lipids (including waxes and lipid derivatives). These coatings offer benefits such as moisture resistance, which is crucial for extending the shelf life of various foods. However, lipid-based coatings may lack transparency and flexibility and are susceptible to rancidity over time.

Edible Packaging Types

Edible packaging types encompass a diverse range of innovative options, each with its unique properties and applications:

  • Edible wrappers and containers: These are often made from ingredients like rice, seaweed, or edible plant materials. Edible containers and edible plastic wraps also add a unique flavor and texture to dishes. They are used for packaging sushi, rice balls, and takeaway foods. One drawback is that they can be less durable than traditional packaging and may require specific handling.
  • Edible gelatin capsules: Gelatin capsules are derived from animal collagen and have no odor or taste. They are commonly used for encapsulating pharmaceuticals and dietary supplements as they dissolve quickly, releasing their contents. Gelatin capsules are not suitable for all food products, and they may have limitations in terms of flavor retention.
  • Edible baking cups: Typically made from ingredients like wheat flour, these cups are designed to withstand baking temperatures. They are used for baking muffins, cupcakes, and other baked goods. Edible baking cups eliminate the need for disposable paper or plastic liners. While they add a delightful crunch to baked treats, they are not as versatile as other edible packaging types, as they can be used only for baking.

Evolution of Edible Packaging Technology

The journey of edible packaging technology has been a fascinating one, marked by significant milestones.

For example, did you know that the very first edible packaging dates to 12th century China, where citrus fruits were coated with wax to preserve their moisture?

Also, most food packaging up to the 20th century was, in fact, edible. However, during the 20th century, petroleum-derived plastics took over the packaging world and became the standard because of their convenience and cost-effectiveness.

But, in recent decades, the need for more sustainable and eco-friendly solutions has required the food industry to return to the more natural edible packaging solutions.

From the early experiments with biopolymers to the development of edible films and coatings, it has been a testament to human ingenuity and a commitment to reduce plastic waste.

Challenges and Limitations of Edible Package Solutions

While edible packaging represents a promising solution to combat food waste and reduce environmental impact, it isn’t without its share of challenges and limitations.

  • Technological hurdles: Developing edible packaging materials that can effectively preserve a wide range of foods while maintaining taste, texture, and safety can be technologically demanding. Finding the right balance between biodegradability and functionality is still a significant challenge.
  • Cost considerations: The truth is that edible packaging materials often are more expensive than conventional packaging. The production costs associated with sourcing and processing natural ingredients for edible packaging can pose financial challenges, potentially leading to higher product prices.
  • Food compatibility: Not all food products are suitable for edible packaging. Unfortunately, items with high moisture content or specific storage requirements may not be compatible with current edible packaging solutions, limiting their application.
  • Climate and storage: Environmental conditions, such as temperature and humidity, can affect the stability and shelf life of edible packaging. Adapting these materials to different climates and storage environments poses logistical challenges.
  • Consumer acceptance: This is a crucial factor in the success of edible packaging. While many consumers are eager to embrace eco-friendly solutions, others may be hesitant to change their packaging preferences, leading to potential marketing challenges.
  • Regulatory considerations: The regulatory landscape surrounding edible packaging can be complex. Ensuring that these materials meet safety and quality standards while navigating varying regulations across regions can be a hurdle for manufacturers.

Benefits of Edible Packages

Edible packaging offers a multitude of environmental benefits, making it a compelling solution in the quest for sustainable food systems.

  • Reduced plastic waste: One of the most significant advantages of edible packaging is its potential to curb plastic waste. Landfills and oceans are overflowing with conventional plastic packaging waste. According to estimates, global plastic production for packaging surpassed 140 million tons in a single year, and edible packaging can substantially mitigate this environmental burden.
  • Biodegradability: Unlike traditional plastics, which can persist in the environment for centuries, edible packaging materials naturally biodegrade. This means that when discarded, edible packaging breaks down into harmless organic compounds, leaving no lasting ecological footprint. This characteristic aligns perfectly with the principles of a circular economy, reducing the burden on landfill sites.
  • Lower carbon emissions: Edible packaging also has the potential to lower carbon emissions throughout the entire product lifecycle. The production of traditional plastic packaging relies heavily on fossil fuels, contributing to greenhouse gas emissions. In contrast, edible packaging materials are often sourced from renewable resources, reducing the carbon footprint associated with their manufacturing.
  • Food waste reduction: Edible packaging can play a pivotal role in minimizing food waste. By preserving food freshness and extending shelf life, it prevents spoilage and the need for premature disposal. In the United States alone, over 30% of food produced is wasted, and edible packaging can help reverse this trend, making a substantial dent in the food waste crisis.
  • Sustainable sourcing: Many edible packaging materials are derived from sustainable sources, such as plant-based biopolymers. These materials can be grown, harvested, and processed with minimal environmental impact, further enhancing their eco-friendly profile.
  • Consumer appeal: The environmental consciousness of consumers is on the rise. Edible packaging aligns with consumer preferences for eco-friendly options, enhancing brand reputation and marketability.
