How to Store Oca After Harvest?

Oca, scientifically known as Oxalis tuberosa, is a tuberous root vegetable native to the Andean region of South America. It is a popular crop due to its high nutritional value and versatility in culinary applications. Proper storage of oca after harvest is crucial to maintain its quality and extend its shelf life.

Harvesting Oca

Oca tubers are typically ready for harvest when the foliage starts to die back and turn yellow. To harvest oca, gently loosen the soil around the base of the plants using a garden fork or shovel. Carefully lift the tubers from the ground, taking care not to damage them. Remove any excess soil clinging to the tubers, but avoid washing them as this can promote rotting during storage.

Curing Oca

Before storing oca, it is important to cure the tubers to toughen their skins and enhance their flavor. Lay the harvested oca in a single layer on a dry, well-ventilated surface, such as a wire rack or a clean, dry table. Allow the tubers to cure for about two weeks in a cool, dark place with moderate humidity. This process helps the tubers develop a protective layer and reduces the risk of spoilage during storage.

Storage Conditions

Once the oca tubers have been properly cured, they can be stored in a cool, dark, and well-ventilated location. The ideal storage temperature for oca is around 40-50°F (4-10°C), with a relative humidity of 60-70%. Avoid storing oca in areas prone to temperature fluctuations or high humidity, as this can lead to sprouting, rotting, or mold growth.

It is recommended to store oca in breathable containers, such as mesh bags or wooden crates, to allow for proper air circulation. Avoid using plastic bags or airtight containers, as they can trap moisture and promote decay.

Regular Inspection

During storage, it is essential to regularly inspect the stored oca tubers for any signs of decay, mold, or sprouting. Remove any damaged or spoiled tubers immediately to prevent the spread of rot to the healthy ones. Additionally, check the storage environment for any changes in temperature or humidity and make necessary adjustments to maintain optimal conditions.

By following these storage guidelines, you can ensure that your harvested oca tubers remain fresh and flavorful for an extended period, allowing you to enjoy this nutritious crop throughout the year.
