The simplest rule for anyone with a tree nut allergy? Treat all almond extracts as guilty until proven innocent. While many people with mild allergies can tolerate synthetic versions, the variability in manufacturing means no bottle is 100% consistent. One batch might have trace proteins, another might not.
A 2026 study in the Journal of Food Allergy noted that nearly 15% of “almond extract” samples from various brands contained detectable almond protein residues. That’s a gamble most allergists advise against—especially since reactions can escalate unexpectedly. Better to swap in a different flavor than to spend the night in an ER.
