Freeze-drying broccoli sprouts without pre-freezing can lead to the reaction of glucoraphanin and myrosinase, resulting in no significant sulforaphane.

“You can actually freeze dry broccoli sprouts very nicely as long as you deep freeze them, or quick freeze them and maintain them in a frozen state when you go to dry them.”

“by far the easiest way to to preserve them i think is to just spread them out on a cookie tray or a you know a baking tin put wax paper on it if you want and quick freeze them and then when you quick freeze them you can bundle them and put them in a bag or a container and and then you can keep them for you know weeks or even months”
