on Citrus Red No. 2 and Orange B, both of which present health risks and are gradually being phased out in place of natural alternatives like turmeric and beet extract. 

In Thailand, a similar shift is occurring. Brands are switching to natural food coloring in response to a list of products shared by the Thailand Consumer Council that contain Sunset Yellow FCF, an artificial orange-yellow food coloring linked to hyperactivity and shortened attention spans in elementary school children. 

The dye is also proven to potentially cause cancer and kidney disease, according to food technology specialist Nuti Hutasingh, and has already been banned in numerous European countries. Despite the health concerns, Thailand’s Food and Drug Administration still permits the use, limited to 100 milligrams per kilogram. 

Sunset Yellow FCF is responsible for the signature orange color of Thai tea, a popular drink that can be found on street corners and at cafes throughout the country and around the world. Also known as Cha-Thai, Cha-nom-yen or Cha-yen, it’s an iced brewed tea blended with milk and sugar that’s become a signature drink of Thailand.

Swapping artificial coloring for natural ones may forever change the iconic color we’ve come to associate with Thai tea, but it spotlights a growing trend among Thai consumers looking for healthier alternatives.
