Best Answer

Blanching is the scalding of vegetables in boiling water or steam. Blanching slows or stops the action of enzymes. Up until harvest time, enzymes cause vegetables to grow and mature. If vegetables are not blanched, or blanching is not long enough, the enzymes continue to be active during frozen storage causing off-colours, off-flavours and toughening. Blanching time is crucial and varies with the vegetable and size of the pieces to be frozen. Under-blanching speeds up the activity of enzymes and is worse than no blanching. Over-blanching causes loss of flavour, colour, vitamins and minerals.

Do you have to blanch corn before freezing?

Corn does not need to be blanched before freezing. The excess liquid in it will cause the corn to expan upon freezing and then wrinkle more when defrosted. The caveat to all of this is that you do need to cook the corn thoroughly at a high enough temperature to kill any bacteria no matter which path you choose to take.
