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.

쌀의 미성숙상태의 whole grain인 dough ripe stage rice(DRSR, 호숙기)와 yellow ripe stage rice(YRSF, 황숙기) flours의 호화특성을 분석하고, 각각 30% 첨가한 백설기를 제조하여 그 품질 특성을 조사하였다. RVA 분석 결과, 30% DRSR와 YRSR flour은 완숙기 멥쌀(FRSR, control) flour 보다 호화 속도와 호화액의 안정성은 증가하는 것으로 나타났다. DRSR과 YRSR을 중량대비 30%를 첨가하여 제조한 백설기의 수분함량은 DRSR와 YRSR flour 자체의 낮은 수분함량에 의해 완숙기(FRSR, control) flour로 제조된 백설기보다 낮게 나타났다. 백설기의 색도는 강한 greenness와 yellowness가 나타났는데, 이는 DRSR와 YRSR flour자체의 고유색에 의해 영향을 받아 나타난 것으로 사료된다. 한편, 조직감의 경우, adhesiveness, springiness, cohesiveness, chewiness와 resilience는 30% DRSR와 YRSR를 첨가한 백설기가 control보다 낮게 분석되었는데, 이는 DRSR과 YRSR 자체의 낮은 수분함량으로 인해 백설기 제조 시 위의 조직감 특성들에 영향을 받은 것으로 사료된다. 관능검사 결과, 30% DRSR와 YRSR 백설기의 green color와 greenish taste는 DRSR와 YRSR 고유의 색과 향에 의해 control에 비해 높게 나타났으며 전반적인 기호도는 30% DRSR 백설기가 가장 높았으나 control과 유의적인 차이가 없었다. 이상의 결과, 미성숙 전곡립 DRSR를 30% 첨가하여 백설기를 제조한다면 색과 맛 그리고 향이 부여되며 전반적인 기호도가 완숙기 일반 멥쌀로 제조한 백설기와 유사하여 백설기의 부재료로 이용이 가능할 것으로 보인다. 또한, 본 연구에 제시된 결과들은 제조당일의 백설기 품질 특성을 조사한 것으로, 앞으로 저장기간을 통한 백설기의 노화에 관한 품질특성 연구가 필요할 것으로 사료된다.
