Is Pepsi Vegan?
It Depends
Not certifiedClassic Pepsi cola is vegan, and PepsiCo has confirmed that most of its Pepsi lineup (including Pepsi Max and its flavor variants) is suitable for vegans. The exception is Diet Pepsi, which PepsiCo has confirmed is NOT vegan, though the company refuses to say which animal-derived ingredient is responsible.
The catch: Diet Pepsi contains an undisclosed animal-derived ingredient. PepsiCo has confirmed it exists but calls the detail "commercially sensitive information" and will not reveal it. Because Diet Pepsi is still suitable for vegetarians, the ingredient is likely a processing aid (such as a fining agent like isinglass or casein) rather than a labeled component like gelatin or milk powder.
