GLORIO, P. et al. Dietary fiber in fruits, roots, tubers, cereals and pulses from peruvian cultivars. Rev. Soc. Quím. Perú [online]. 2008, vol.74, n.1, pp.46-56. ISSN 1810-634X.

Peruvian cultivars have called attention due to their bioactive components, but no dietary fiber information was available. This work determines Total Dietary Fiber (TDF), soluble fiber (SF) and insoluble fiber (IF) by AOAC 985.29 methodology. Among the fruits studied the highest IF content was found in lucuma, palo variety (31,66±0398 %dm) and the highest SF contents in chirimoya (6,65±0,215 %dm) when expressed this value over fresh weight. In roots and tubers the highest values of TDF were found in maca (22%dm), followed by mashua (14,4%dm), yacon (14,4 %dm) and potato, yungay variety (14,9 %dm). Killo acoto, native potato,stood out for its high TDF content (12,5%dm) and the highest value of SF (4,3±0,636 %dm) among native potatoes. Between cereals, Kaniwa cupi variety showed the highest values for TDF (27,6%dm). Between pulses, beans showed highest TDF values specially the caraota negra variety.

Keywords : dietary fiber; fruits; cereals; pulses; native potatoes; mashua; maca.
