Traditionally Yacon is grown in northern and central Andes from Colombia to Northern Argentina for its sweet tasting, crisp and tuberous roots. It is well cultivated in Tasmania, Southern Australia and New Zealand. Recently it has been introduced to Malaysia, Philippines, Czech Republic, Southern USA, Russia, Korea, Taiwan and Japan. Yacon is also known as Bolivian sunroot, Strawberry jicama, Earth Apple, Sweet root, Yacon Strawberry, Yacón and Peruvian ground apple.
Yacon is a close relative of Jerusalem artichoke and sunflower. The plant have perennial rhizome which are attached succulent storage roots. Rhizomes form under the surface of soil and produce aerial shoots continuously. An edible storage tuber weighs from few hundred grams to a kilogram. The plants produce small and inconspicuous flowers in yellow color at the end of growing season.
Tubers have fructooligosaccharide which is an indigestible polysaccharide made of fructose. Fructooligosaccharides have sweet taste which pass unmetabolised through human digestive tract as it have low caloric value. Due to its prebiotic effect, it is used by beneficial bacterial that promotes colon health and supports digestion.
Yacón plants can easily grow to around 2 m in height and provide small, inconspicuous yellow flowers at the conclusion of the growing season. Unlike a number of other root vegetables domesticated by the indigenous peoples of the Andes (ulluco, oca, and mashua), yacón just isn’t photoperiod sensitive, and may create a industrial yield within the subtropics, too.
Traditionally, yacón roots are developed by farmers at midelevations on the eastern slopes of the Andes descending toward the Amazon. It really is developed occasionally along field borders where the juicy tubers supply a welcome source of refreshment during field work. Till as recently as the early 2000s, yacón was rarely recognized just outside of its restricted native range, and was unavailable from urban markets; however, press reports of its used in Japan because of its proposed antihyperglycemic qualities made the crop extensively known in Lima along with other Peruvian cities. Companies also have developed novel products like yacón syrup as well as yacón tea. Both products are well-liked by diabetics as well as dieters.
