(SFGATE) — NEW YORK (AP) — Diet Pepsi is quietly changing its sweetener ahead of a major rebranding of the soft drink set for next month.
The change comes as PepsiCo Inc. looks to reinvigorate its namesake brands after losing market share to Coca-Cola Co. in recent years.
Cans of Diet Pepsi around the country now list a mix of two artificial sweeteners, a pairing that is commonly found in newer diet sodas. Previously, Diet Pepsi used only aspartame, which is sensitive to heat and breaks down more easily.
