Evaluation of Amylose/Amylopectin, Dietary Fiber, Sugar and Vitamin C in Two Processed and Unprocessed Hydroponic Sweetpotato Cultivars 2008-01-2174

Spaceflight introduces the human body to extremes not normally experienced in daily life to supplement the body's natural protections for some of the negative effects; important nutrients must be included in an astronaut's diet. Therefore the objective of this study was to evaluate chemical properties (amylose/amylopectin, dietary fiber, sugars and vitamin C) in two processed and unprocessed hydroponic sweetpotato cultivars. In both cultivars dietary fiber ranged from 0.4% to 3%. Amylose/Amylopectin ratio in both cultivars ranged from 1/99% to 14/86%. Glucose and sucrose were the dominant sugars in both cultivars. Vitamin C was reduced 35-50% when processed.
