                                While some processed foods do contain propylene glycol as a moisture-retaining agent, an analysis of Kellogg's Pop-Tarts ingredients shows that propylene glycol is not present in their standard U.S. formulations. Instead, common varieties of Pop-Tarts use other ingredients to maintain texture and freshness.
