Pepsico is removing the artificial sweetener Aspartame from its Diet Pepsi products in US, starting this August.

The company believes the move will arrest the fall in sales in the US.

The move also follows the rising consumer concerns about Aspartane over its safety.

Diet Pepsi, Wild Cherry Diet Pepsi and Caffeine Free Diet Pepsi will now feature a blend of acesulfame potassium and sucralose.

However, Diet Coke will continue to use Aspartane.

Company officials, however, continue to cite various studies supporting the safety of the sweetener.

Senior vice president of Pepsi and Flavors Portfolio, PepsiCo North America Beverages, Seth Kaufman said: "We recognize that consumer demand is evolving and we’re confident that cola-lovers will enjoy the crisp, refreshing taste of this new product."

Aspartame was approved by the US FDA in 1981.

Pepsi India is expected to follow suit as sales of diet sodas have declined there too, because of health concerns.
