Fermentation extracts (enzymes)

Watched ingredients get highlighted on every product panel you open.

Where it comes from
Industrial fermentation, the same process behind most food-industry enzymes.
Why it's in the product
Break down starch, fiber, and protein to improve digestibility.
Safety and toxicity
Safe. Aspergillus on a label alarms people who associate the genus with aflatoxin, but the food-grade production strains used here are non-toxigenic and the extract is not the mold.
