TADCASTER, England, Feb. 7 (UPI) -- Newcastle Brown Ale's recipe is being changed after many customers expressed concern over the caramel coloring used in the beer.
Customers are concerned the chemical 4-methylimidazole, a caramel coloring additive used in the ale, could cause cancer. The company that makes the beer, Heineken, said it will change the recipe so roasted malts will maintain the ale's color.
"The amount [of the chemical] used in Newcastle Brown Ale is well within the recommended safe levels set by [health authorities]," said a company spokesman. "However, we listened to consumer concerns that have been expressed, particularly in the USA, and chose to review our recipe."
The European Food Safety Authority has judged the level of caramel coloring in the ale as safe for consumption twice now, but the company is changing the recipe to make its customers happy.
It is said the change in recipe will not affect the taste, but it could slightly affect the color.
A study from 2007 found that high levels of 4-methylimidazole were linked to increased risk of lung cancer and leukemia in mice.
