This study shows the quality changes of Sulgidduk added Cheonnyuncho fruit powder during storage. Sulgidduk was prepared with freeze-dried Cheonnyuncho, rice flour, sugar syrup and salt. The Sulgidduk, which was made with various amounts (0,3,6,9,12%) of added Cheonnyuncho, was examined by the quality of duration during storage. The pH of Cheonnyuncho Sulgidduk decreased as the amounts of Cheonnyuncho fruit powder increased, and also showed a significant decrease as the storage increased. As the amounts of Cheonnyuncho fruit powder increased, lightness (L) decreased while redness (a) and yellowness (b) increased. During the storage period, the lightness (L) and yellowness (b) were increased, but redness (a) was decreased. In the texture profile analysis, the hardness and springiness were decreased with increasing Cheonnyuncho fruit powder, whereas cohesiveness, gumminess and brittleness were increased. However, the tendency of the changes of characteristics during storage was opposite except for springiness. In conclusion, it is suitable to extend the storage period of Sulgidduk added Cheonnyuncho fruit powder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
