The study explores the sensory properties of Backsulgi prepared with dry non-glutinous rice flour sweetened with various sweeteners(sugar, honey, oligosaccharide, trehalos, erythritol and accesulfame K). Sensory attributes of Backsulgi were evaluated by quantitative descriptive analysis(QDA), PCA and PLSR. The QDA results revealed that the sample sweetened with trehalose showed highest value in dryness, and samples with accesulfame K, honey and erythriol had relatively high levels in moisture and springiness. Principle component analysis (PCA) results showed 78.89 % of the total variation with PC1 (54.92%) and PC2 (23.98%), respectively. The samples with accesulfame K(AF) and honey, which showed high values in moisture level, springiness and sweet taste, showed similar attributes which led to a positive direction of PC1. The correlation between the sensory attributes and consumer acceptance showed that the most important factors for high consumer acceptance were moistness, springiness, sweet taste and sweet flavor. Overall, the samples with accesulfame K(AF) had the closest position in the PLSR results with highest overall consumer satisfaction.

The purpose of this study was to identify appropriate sweeteners that could improve the dryness, while reducing calorie by adding various sweeteners to Sulgitteok using dry non-glutinous rice flour. Of six sweeteners (sucrose, trehalose, honey, acesulfame K, oligosaccharide, and erythritol) added, Sulgitteok with acesulfame K had the highest moisture content, whereas Sulgitteok with trehalose had the lowest moisture content. The moisture content of all samples were decreased when storage period was increased except the sample added with trehalose. Sulgitteok with erythritol had the highest L-value, whereas Sulgitteok with oligosaccharide had the lowest L-value. The L-value and b-value of Sulgitteok samples decreased when storage period was increased. Sulgitteok with trehalose had the highest hardness, whereas Sulgitteok with oligosaccharide had the lowest hardness. The hardness increased in all samples when storage period was increased. Sulgitteok sweetened with acesulfame K and honey had the highest acceptance.
