That vibrant green hue in your favorite mint syrup is a carefully crafted illusion, and according to consumer watchdog Yuka, it is a dangerous one. The product-scanning app has launched a new campaign demanding manufacturers remove the artificial colorant known as Brilliant Blue FCF (E133) from their mint-flavored drinks, arguing that the purely cosmetic additive poses unnecessary health risks to millions of consumers.
The core of the issue is a sensory deception. Industrial mint syrups rarely derive their flavor from steeping real green leaves. Instead, they use flavoring compounds extracted from the plant, which are naturally colorless or slightly yellowish. To meet consumer expectations that mint should look green, brands systematically dose the liquid with E133. According to Yuka’s database, this dye is present in a staggering 65% of mint syrups sold in France, appearing across major national brands and private-label distributor products.
A Colorant with a Dark Side
Yuka’s campaign, launched on Tuesday, June 16, frames E133 as an additive with zero nutritional or preservative value. The organization insists its removal is a matter of public health. While currently authorized by European regulations, the dye is highly controversial in scientific circles.
Research has long suspected a link between E133 and hyperactivity and attention disorders in children. More recent studies raise deeper alarms, suggesting the substance may damage DNA and impair cellular function or survival. Furthermore, certain formulations of this additive can contain aluminum, a metal suspected of causing genetic damage and increasing the risk of severe long-term conditions, including multiple sclerosis, asthma, epilepsy, and Alzheimer’s disease.
The High Cost of a Clear Alternative
The frustrating reality is that healthier, transparent versions of mint syrup already exist. Yuka’s comparison of 12 different product references found that 9 brands already offer a colorless version without E133. The barrier to a wider switch is purely economic.
The analysis reveals a significant “green premium” for safer products. The average price for a mint syrup containing Brilliant Blue FCF sits at €4.08 per liter. In stark contrast, the dye-free version averages €6.14 per liter—a markup of €2.05. This gap is exemplified by market leader Teisseire, whose transparent mint syrup is sold at a 23% higher price point than its artificially colored counterpart. This discrepancy is often attributed to lower sales volumes for the healthier alternative.
Yuka argues that this price gap effectively penalizes health-conscious consumers. The organization is directly challenging manufacturers to stop reserving clean-label recipes for premium organic ranges. Their demand is clear: generalize the transparent versions and eliminate the significant surcharge, ensuring that a glass of mint syrup doesn’t come with a hidden side of chemical risk.
