Brassicas (also called cruciferous vegetables) include broccoli, cauliflower, cabbage, Brussels sprouts, kale, bok choy, and kohlrabi. These vegetables are part of the Brassicaceae family.

Most brassicas require refrigeration with high humidity. They are ethylene-sensitive and should be stored away from ethylene-producing fruits. Proper storage helps maintain their crisp texture and prevents yellowing.
