It is important to blanch fresh vegetables before freezing them in order to denature the enzymes. By denaturing the enzymes, it prevents off-flavours, faded colours, musty hay-like odours and tough textures to occur during frozen storage.
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.
Fresh food still contains the majority of Vitamins.
Blanching is a cooking technique where food is briefly boiled and then immediately cooled in ice water. The purpose of blanching is to partially cook the food, which helps to preserve its color, texture, and flavor. It also helps to remove any impurities or strong flavors. Blanching enhances the final dish by ensuring that the food retains its vibrant color, firm texture, and fresh taste.
