Kohlrabi

Harvesting and Handling

Kohlrabi is grown as an annual, with the enlarged stem being the most commonly used edible portion. The enlarged stem may have purple, white or green skin but the flesh is white. The leaves can also be eaten like collards.

Only young kohlrabi should be harvested, since mature product becomes woody and tough. Leaf stems are a good indicator of quality; they should be succulent and tender.

Topped kohlrabi is usually packaged in film bags. Those with tops are usually bunched tied together like beets.

Cooling and Storage

Topped kohlrabi can be stored for 2 to 3 months at 0°C and 98% to 100% RH. Storage life is 2 to 4 weeks if tops are not removed. Storage-life can be improved with the uses of perforated film bags to maintain high RH around the product.

Kohlrabi are not chilling sensitive.

Controlled atmosphere considerations

There is no benefit from CA.
