Food packaging that's good enough to eat

American Chemical Society

These days, many people are concerned about plastic waste; however, the convenience, mechanical properties and cost of plastic food packaging are hard to beat. But now, a growing number of innovators and entrepreneurs are trying to make edible packaging and tableware from foods like seaweed, milk proteins and potato starch, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, produced in collaboration with ACS Central Science

Edible films, wrappers and straws have already found a specialty market and are starting to attract attention from larger food and beverage companies, according to freelance contributor Prachi Patel. At the 2019 London Marathon, the start-up company Notpla handed out sports drink pods, packaged in seaweed-based capsules, to thirsty runners. Although the packaging is safe to swallow, runners can choose to spit out the film. In that case, it biodegrades in only 4-6 weeks. The New York-based company Loliware is making seaweed- and algae-based straws that feel like plastic for 24 hours after getting wet. Once used, they can be eaten, or they will degrade in the environment within 2 months. Marriott Hotels and alcoholic-beverage firm Pernod Ricard have already started using the straws.

Although edible packaging is gaining ground, challenges remain. Some worry about the hygiene of eating packaging that has been touched or exposed to germs during transport or while sitting on the shelf. Experts agree that edible packaging will require an outer layer, but these materials could also be made from compostable or sustainable materials, such as paper. Another obstacle is public acceptance: will people eat something that is usually thrown away? Consumers could perhaps be convinced if the packaging includes nutrients, such as vitamins or proteins, or just tastes good. And finally, improvements in heat and moisture stability need to be made before edible packaging can enjoy widespread use.

The American Chemical Society (ACS) is a nonprofit organization chartered by the U.S. Congress. ACS' mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and its people. The Society is a global leader in providing access to chemistry-related information and research through its multiple research solutions, peer-reviewed journals, scientific conferences, eBooks and weekly news periodical Chemical & Engineering News. ACS journals are among the most cited, most trusted and most read within the scientific literature; however, ACS itself does not conduct chemical research. As a specialist in scientific information solutions (including SciFinder® and STN®), its CAS division powers global research, discovery and innovation. ACS' main offices are in Washington, D.C., and Columbus, Ohio.
