Abstract

Yacon (Polymnia sonchifolia or P. edulis; Compositae or Asteraceae) plants originating from the Andean highlands have large (100-500 g FW) subterranean tubers, and the fresh, boiled or fried tubers are edible. The appearance of the yacon tubers is similar to that of the dahlia or sweet potato tubers, but the fresh yacon tubers are juicy and sweet like fruits such as pears. Recently, yacon cultivation has been introduced to Japan.
