Pepsi on 10th of august will start selling its reformulated Diet Pepsi with sucralose and Ace K (acesulfame potassium) in stores across the U.S, after two years of extensive research. But Coke says they have no plans to match the move made by their arch rival Pepsi.
"We will not be changing the sweetener for Diet Coke," said Coke spokesman Scott Williamson. "Americans have fallen in love with Diet Coke, the No. 1 zero-calorie sparkling beverage, because they enjoy its taste."
Diet Pepsi is getting rid of its aspartame in response to consumer complaint to the artificial sweetener, which many have labeled as unhealthy. However Coke said that Coke with Splenda uses the same ingredient found in Aspartame-free Diet Pepsi.
The backlash against aspartame has caused the sinking sales volume of both Diet Pepsi and Diet Coke, which were down 5.2 percent and 6.6 percent, respectively, in 2014.
While Pepsi maintains aspartame is safe, consumers ultimately felt differently and the company listened, said Pepsi Trademark senior vice president Seth Kaufman. Pepsi tested the new formula has the same Diet Pepsi flavor, Kaufman said. "This is not something we took lightly," he said.
