The "mold-like roots" on broccoli sprouts are actually root hairs, which are tiny, white, fuzzy fibers that are a normal and edible part of the sprout's root system, growing when the sprouts need water. To differentiate from mold, which appears like cobwebs spreading across the sprouts and has a foul smell, rinse the sprouts to see if the fuzz disappears. If it vanishes and the sprouts have an earthy smell, they are healthy. If the fuzz stays, smells bad, or looks like a spiderweb, it's mold, and the sprouts should not be eaten。
