While mature broccoli does contain sulforaphane, the levels are considerably lower than in sprouts. The exact amount can vary based on factors like the broccoli variety, how it's prepared, and even how long it's cooked, since heat can degrade the enzyme myrosinase needed to produce sulforaphane.
The concentration of sulforaphane in broccoli sprouts is much higher due to the young stage of growth where defense compounds like glucosinolates (which include glucoraphanin) are more concentrated.
To maximize sulforaphane content, both sprouts and broccoli should be eaten raw or lightly cooked. Cooking methods like boiling, steaming, or microwaving can reduce the amount of sulforaphane by inactivating myrosinase.
There's also variability in sulforaphane content due to different broccoli varieties, growing conditions, and the age of the plant at harvest. Broccoli sprouts are generally more consistent in their high glucoraphanin content.
The baby vegetable market may boom. It has always seemed like growing trays of veggies on the patio would be worthwhile. Then, I think about the summer in Texas. They would wilt.

I grow my own sprouts. It is easy to do. But broccoli sprouts are too spicy or rank for me. Perhaps I should mix them with clover or alfalfa seed.
