Pachyrhizus erosus, commonly known as Jícama, Yam, and Mexican Turnip, is the name of a native Mexican vine, although the name most commonly refers to the plant’s edible tuberous root. Jícama is one species in the genus Pachyrhizus. Plants in this genus are commonly referred to as yam bean, although the term “yam bean” can be another name for jícama. The other major species of yam beans are also indigenous within the Americas.
Jícama is often paired with chili powder, cilantro, ginger, lemon, lime, oranges, red onion, salsa, sesame oil, grilled fish and soy sauce. It can be cut into thin wedges and dipped in salsa. In Mexico, it is popular in salads, fresh fruit combos, fruit bars, soups, and other cooked dishes.Very high levels of oil and fat In contrast to the root, the remainder of the jícama plant is very poisonous; the seeds contain the toxin rotenone, which is used to poison insects and fish.
Jícama is high in carbohydrates in the form of dietary fiber. It is composed of 86-90% water; it contains only trace amounts of protein and lipids. Its sweet flavor comes from the oligofructose inulin (also called fructo-oligosaccharide) which is a prebiotic.
