The Quality Characteristics of Backsulgi with Dough Ripe Stage Rice and Yellow Ripe Stage Rice

Abstract

The effect of the addition of dough ripe stage rice (DRSR) and yellow ripe stage rice (YRSR) on the quality characteristics of Backsulgi was investigated. The DRSR and YRSR addition ratio of 30% was selected by preliminary sensory evaluation study for which backsulgi was prepared with DRSR added to full ripe stage rice (FRSR, control) as the weight ratio of 0, 20, 30 and 50%. The pasting properties of 30% added DRSR and YRSR flours, analyzed with rapid viscosity analyzer (RVA), were compared with FRSR flour. The RVA values of holding, breakdown, final viscosities were higher in 30% DRSR and YRSR flours than in control. Backsulgi prepared with 30% DRSR and YRSR showed lower moisture content along with higher greenness and yellowness than control. As a result of analysis with texture analyzer, adhesiveness, springiness, cohesiveness, chewiness and resilience were lower in backsulgis with 30% DRSR and YRSR than in control. In the sensory evaluation, backsulgis with 30% DRSR and YRSR were assessed as having more intensive green color, and more greenish and delicious taste than control. Furthermore, backsulgi with 30% DRSR showed higher score of overall acceptability than 30% YRSR (p<0.05), and not significantly different score with control (p>0.05). Therefore, the addition of 30% DRSR could give favorable color and flavor to backsulgi.
