Enzymes in Frozen and Dehydrated Foods

[Bananna]

Does anyone know of studies that show that frozen and dehydrated foods still have intact enzymes?
I get that we *know* cooked food doesn't, but do we *know* that frozen or dehydrated food DOES?
Thanks,....just kinda wondering.

I recall a post here at least a year ago where someone said that they had sprouted seeds that they had previously dehydrated.
Would whoever posted that please put your hand up.

I have read that frozen food can contain some enzymes but if the temp is to high you can start to lose them. You can always assume that you can lose some nutrients but it probably won't be as bad as cooking.

Commercialy frozen foods will usually have been blanched in boiling water before being frozen.
I do not think that this will kill all of the enzymes because of the short duration but it will kill some.
