Dongwon F&B upgrades seaweed packaging in global export push

Dongwon F&B has implemented a nitrogen-flush packaging method for its Yangban brand roasted seaweed as part of an effort to boost global exports, marking the 40th anniversary of the product's launch. The technique involves replacing oxygen within the package with nitrogen, a less reactive gas, which helps preserve the seaweed's fresh, crunchy texture and prevents oxidation that can cause off-flavors.

This method eliminates the need for silica gel packets, which are typically used to absorb moisture and maintain quality during shipping. Dongwon F&B estimates that this change will save approximately 300 tons of silica gel annually. The company plans to use the nitrogen-flush method in combination with silica gel packets for its export products, extending their shelf life from six months to 12 months. Currently, Yangban seaweed is available in more than countries.
