Dongwon F&B is celebrating the 40th anniversary of its 'Yangban Gim' by introducing a nitrogen packaging method to enhance product freshness and strengthen its presence in international markets.
On August 20, Dongwon F&B announced the application of the 'Fresh-Lock' nitrogen packaging method, which reduces internal oxygen levels and replaces them with nitrogen.
This technology inhibits oxidation, which can degrade the quality of seaweed snacks. Over time, oils in the seaweed can react with oxygen, leading to off-flavors and a loss of crispness. By injecting nitrogen, which is less reactive, the company aims to maintain the fresh, crispy texture and nutty flavor of the seaweed without the need for silica gel. Dongwon F&B estimates that this will reduce its annual silica gel usage by about 300 tons.
For export products, both the nitrogen packaging method and silica gel will be used to minimize quality degradation during the longer transportation times associated with international shipping. This innovation has doubled the shelf life of Yangban Gim from six months to twelve months. Currently, Yangban Gim is exported to over 30 countries, including Japan, Thailand, and the United States. Dongwon F&B plans to further expand its overseas sales channels with this new method.
This is not the first time Dongwon F&B has improved its packaging. In 2020, it became the first in the industry to introduce an 'eco-package' that eliminated plastic containers. The company addressed the issue of seaweed tearing upon opening by utilizing laser-cutting film, resulting in an annual reduction of about 30 tons of plastic usage.
Launched in April 1986, Yangban Gim has led the market through consistent quality control and technological development. The company operates a 'raw material inspector' system to manage the quality of seaweed from the planting stage to harvest. It was also the first in the industry to use aluminum packaging to block oxygen and light. To date, cumulative sales have reached 12 billion sheets of seaweed.
To celebrate its 40th anniversary, Dongwon F&B is hosting a consumer event. Customers can participate by posting photos of Yangban Gim products and receipts on Instagram or sharing quiz results until September 20, with a chance to win gold and AirPods Pro 3.
A representative from Dongwon F&B stated, "As the number one brand in the seasoned seaweed market, we have adopted the nitrogen packaging method to provide better quality seaweed to consumers. We will continue to enhance our quality competitiveness throughout the entire process, from raw material management to packaging."
