Snacking is becoming such a mainstream mode of eating, more people are consuming snack foods between meals and as meal replacements. More companies have been tracking the trends that shape this space and looking to develop products that check those boxes. In Frito-Lay’s latest snack trend list, it expects consumers to be seeking sour and unexpected combinations. Frito-Lay noted that “unexpected” could include flavors like gin or bourbon or multi-layered combinations that combine several trending flavors.
