Is Your Favorite Korean Ice Cream Tainted? Shocking Dye Claims!

A brightly colored ice cream bar imported from China, playfully named the "Merong Bar," is melting under the heat of controversy in South Korea. The treat, shaped like a tongue and marketed for its unique jelly-like texture when melting, has become a massive hit, particularly among children. But its vibrant colors come at a potential cost: the use of tar-based food dyes flagged by the European Union for possible health risks.

The Merong Bar's success story is impressive. GS25, a major convenience store chain, started importing the ice cream last September and quickly sold over five million units. A strawberry-flavored version followed, instantly becoming a top seller. Other chains, like CU and 7-Eleven, jumped on the bandwagon, eager to capitalize on the product's popularity. I've even seen them advertised on social media - they look pretty fun, I have to admit.

The problem? These vibrant hues are achieved using "tar dyes," synthetic colorants derived from coal tar. While widely used in processed foods to enhance their visual appeal, some of these dyes have faced bans or restrictions in Europe and the U.S. due to potential health concerns. It's a familiar story – what's considered safe in one country can be a cause for alarm in another.

Specifically, the Merong Bar contains Blue No. 1, Yellow No. 4, and Red No. 40. All are currently approved for use in South Korea. However, the EU considers Yellow No. 4 a potential trigger for asthma and limits the intake of Blue No. 1 due to worries about hyperactivity in children. Meanwhile, the U.S. Department of Health and Human Services is reviewing Blue No. 1, among other dyes. The fact that these dyes are under scrutiny elsewhere naturally raises questions about their safety here.

The controversy has sparked a national debate. Should South Korea be allowing a top-selling ice cream product to contain ingredients restricted in other developed countries? It’s a legitimate concern, especially when the target demographic is children. Parents are understandably worried about potential long-term health effects.

In response to the growing unease, the Ministry of Food and Drug Safety has announced a reevaluation of food additive standards, including these controversial colorants. This review, scheduled to begin in January 2026, is part of a mandated five-year cycle. The last review concluded in 2019. Hopefully, this reassessment will provide some clarity and reassurance to concerned consumers. Until then, the future of the Merong Bar in South Korea remains uncertain. And parents will likely be doing some extra research before letting their kids indulge in this colorful treat.
