Question

Define the term blanching.

Hint:

Blanching is an essential step before freezing vegetables to maintain quality and nutritional value.

Answer 1

Blanching involves a rapid immersion of fruits or vegetables in boiling water or steam, immediately followed by a swift cooling process in ice water. This technique is employed to inhibit enzymatic degradation responsible for spoilage, which manifests as browning and deterioration of flavor, color, and texture. The primary advantages of blanching are:

• Maintenance of desirable color, flavor, and texture.
• Diminished surface microbial populations.
• Facilitation of freezing or canning for extended storage.

The duration and intensity of blanching are contingent upon the specific produce and the planned preservation strategy.
