How to Store Ulluco After Harvest?

Definition: Ulluco (Ullucus tuberosus) is a root vegetable native to the Andean region of South America. It is an important crop known for its high nutritional value and ability to thrive in high-altitude environments.

1. Harvesting Ulluco

Ulluco is typically harvested when the foliage starts to turn yellow and die back. Care should be taken to gently dig up the tubers using a garden fork or spade to avoid damaging them. It is important to handle the harvested ulluco with care to prevent bruising or injury.

2. Cleaning and Sorting

After harvesting, remove any excess soil clinging to the ulluco tubers. Gently wash them using water, being careful not to scrub or rub them vigorously as this can damage the delicate skin. Sort the tubers, discarding any damaged or diseased ones to prevent the spread of infections during storage.

3. Curing Ulluco

Before storing, ulluco tubers should undergo a curing process to enhance their storage life. Spread them out in a single layer in a well-ventilated area away from direct sunlight. Allow them to dry for about a week, turning them occasionally to ensure even drying. This process helps toughen the skin and reduces the risk of rot during storage.

4. Storage Conditions

Ulluco requires specific storage conditions to maintain its quality and prevent spoilage. The ideal storage temperature for ulluco is around 45-50°F (7-10°C) with a relative humidity of 85-90%. It is crucial to store ulluco in a cool, dark, and well-ventilated place to prevent sprouting and minimize moisture loss.

6. Regular Inspection

During storage, regularly inspect the ulluco tubers for any signs of decay, mold, or sprouting. Remove any spoiled tubers immediately to prevent the spread of diseases. Additionally, check the storage area for any pests and take appropriate measures to control them if necessary.
