Rice Krispies reformulation sparks allergen labeling shift

What's happened

Kellogg’s has reformulated Rice Krispies and Coco Pops to use a mix of rice and corn flours, adding wheat gluten. The change is driven by supply conditions and aims to maintain quality; cereals remain non-HFSS with no artificial additives. Wheat gluten is now an explicit allergen on packs, with bolded ingredients.

What's behind the headline?

Brief

• The reformulation marks a shift in ingredient makeup, not just labeling.
• It introduces wheat gluten as an allergen, changing consumer expectations and packaging notices.

What this means for readers

• Wheat-allergic or coeliac shoppers must check labels more carefully, especially bolded allergens.
• The change may affect taste and texture, which could influence repeat purchases.

Forecast

• If supply pressures persist, further adjustments to other cereals could follow, reinforcing a trend toward mixed flours for stability.

How we got here

The reformulation follows Kellogg’s updates in other markets and aligns with supply challenges affecting rice and grain quality. The Grocer notes a sales backdrop of declining Rice Krispies, while Kellogg’s US arm has pledged to reduce artificial colours by 2027, signaling a broader portfolio shift.
