Health benefits of Ulluco

Second to the potato, Ulluco tubers or Ullucus tuberosus is one of the most economically important and widely grown plants in the Andean region of South America. In fact, it happens to be the staple and predominant root crop in many highland areas of the Andes. Primarily grown as a root vegetable and then as a leafy vegetable, ulluco or sweet cucumber is also known by various other names such as papalisa, ulluku and milluku. The leaves and tubers of this plant are found to contain high levels of nutrients like carotene, calcium, and protein. Ulluco is a main ingredient in many South American dishes. One of the most striking features of this vegetable is that its tubers are varying in color which includes yellow, pink, purple and red colors. Some are even candy striped with waxy and shiny skins.

Ulluco has a crispy texture and this texture is maintained even after being cooked. Although it can be cooked in many ways as you would a potato, frying and baking the vegetable is not a good idea as it has high water content. Boiled Ulluco has the flavor almost similar to that of boiled peanuts but with a firm and crunchy texture. Their skin is soft and thin and hence there is no need of peeling before eating it. Although Ulluco is mostly grown for home use, some farmers consider it an important cash crop that could benefit both the health and economic situation of people living in the highland areas.

Ulluco tubers have a longer shelf life. They keep fresh for almost a year when stored in a dark and cool place at ambient temperatures. When exposed to sunlight, there is the possibility of their skins turning green in color. Canned Ulluco is largely available in the market nowadays. As opposed to many other canned vegetables, canned ulluco retains its natural texture and flavor except for a slight loss in color.

The people of Andes sometimes freeze dry the tubers of ulluco and turn them into a product known as llingli, which keeps for a long time. This product is then ground to make flour that is often added to dishes. When compared to the fresh tubers, the dried ones are more tasty and flavorful. The fresh green leaves of ulluco contain many nutrients, which are considered to be beneficial for the health. These leaves, having a taste similar to that of spinach are usually added to salads or boiled to make a soup.
