Freezing suitability of kale

Brassica oleracea L. (Curly kale Group)

Kale has high suitability for freezing due to the structural strength of its leaves, which allows it to maintain its texture. The quality of the product directly depends on growing conditions and careful preparation of the raw material for storage.

In the reference 26 varieties crop Curly kale, where this is mentioned in the description.

Kale is characterized by high resistance to low temperatures during the growing season. Exposure of the growing plant to natural frosts contributes to the accumulation of sugars, which improves the flavor qualities of the greens. The high structural density of the leaves allows the crop to retain its texture during freezing better than many other leafy vegetables.

Key factors in maintaining quality during freezing are the removal of tough stems and thorough drying of the leaf surface. Excess moisture in the curly structure promotes the formation of ice crystals, which negatively affects the appearance. Blanching is used optionally to neutralize enzymes, preserve color, and reduce the bitterness of the product.
