Abstract
The objective of this study was to develop and standardize a preparation method for low-salt yacon jangachi using rice wine lees. The proximate composition of yacon was 81.08% (moisture), 0.77% (crude protein), 0.14% (crude lipid) and 0.70% (crude ash). In order to determine the preferred sodium concentrations of soaking solution and rice wine lees, we investigated the quality characteristics of yacon jangachi during storage for 50 days at $18^{\circ}C$. The salinity of yacon jangachi using rice wine lees with 2% and 4% salt increased with storage time, but the salinity did not rise above 3% during storage for 50 days. The salinity of rice wine lees with 4% salt decreased during storage time. a and b color values along with sheared force of yacon jangachi increased as storage time increased, but L color value was reversed. In the sensory evaluation, the color preference for yacon jangachi increased during storage time, and the taste preference was highest at day 30. The flavor preference decreased during storage time, but the texture preference was reversed. In the sensory evaluation of overall preference, yacon jangachi using rice wine lees with 0% salt decreased at day 30, whereas yacon jangachi using rice wine lees with 2% and 4% salt increased during storage time. In conclusion, the salinity of yacon jangachi stored for 50 days with 4% salt did not rise above 3%, and softening was not observed.
