pigments. Comparison to staple root foods This table shows the nutrient content of ulluco next to other major staple root crops – potato, sweet potato, cassava, and yam. Taken individually, potato, sweet potato, cassava, and yam, rank among the most important food crops in the world in respect of annual volume of production. Together, their annual production is about 736.747 million tonnes (FAO, 2008). Comparing to these staple root and tuber crops, the nutritional value of ulluco is good and promising for the geographical extent of the crop. The nutritional content for each of the crops listed in the table is measured in its raw state, although staple foods are usually sprouted or cooked before consumption rather than consumed raw. The nutritional composition of the product in sprouted or cooked form may deviate from the values presented. The nutrient composition of the ulluco is given within a range, based on the results of nutritional analyses of ulluco grown in South America.
