초록

고품질 쌀인 적미(자광찰)을 습식제분한 후에 건조하여, 이를 0~12%까지 첨가량을 달리하면서 제조한 백설기의 품질특성을 살펴보았다. 적미 쌀가루의 수분 5.3%, 조단백질 9.5%, 조지방 2.0%, 조회분 1.1% 및 amylose 4.7%이었다. 적미 쌀가루를 첨가한 멥쌀가루의 호화특성은 최고점도, 최저점도, 최종점도, 강하점도 및 치반점도는 적미 첨가량이 증가할수록 감소하였으나, 호화개시 온도는 71.3~72. $2^{\circ}C$로 유의적 차이를 보이지 않았다. 백설기의 색도는 명도(L) 값 48.4~67.2, 적색도(a) 값 -2.5~3.5 및 황색도(b) 값 7.1~7.5이었고, 수분함량은 34.2~38.9%로 적미 첨가량이 증가할수록 L 값은 감소하였으나, b 값과 수분함량은 증가하였다. 백설기의 ${\beta}$-amylase 호화도는 초기에 2.4~3.4 mg/mL에서 1일 후에 0.9~1.6 mg/mL로 저장시간이 증가할수록 maltose의 함량이 감소하였으나, 동일한 시간(제조 1일)으로 비교해보면, RRWM0보다 RRWM12의 maltose의 함량이 약 2.0배 높게 나타났다. 백설기의 조직감은 적미 첨가량이 증가할수록 경도는 증가하였고, 응집성, 탄성 및 씹힘성은 감소하였으나 그 차이는 크지 않았다. 백설기의 관능평가는 색 5.1~7.9, 단맛 6.1~7.0, 씹힘성 4.1~7.3 및 전반적 기호도는 5.8~7.9이었다. 결과적으로 백설기의 호화특성, 수분함량, 색도, 수분함량, 조직감 및 관능평가는 적미 첨가량에 따라서 영향을 받는 것으로 나타났으며, 특히, 적미 첨가랑이 증가할수록 호화특성의 강하점도와 치반점도의 감소, 수분함량과 ${\beta}$-amylase 호화도의 증가는 백설기의 품질개선의 가능성을 보여주었다. 한편, 백설기를 제조할 때, 적미를 12%까지 첨가하여도 조직감은 큰 차이를 보이지 않으며, 적미를 8%로 첨가했을 때, 관능적으로 가장 우수하였다.

The quality characteristics of Backsulgi added with red rice flours at different ratios were investigated to apply in the food industry. The moisture, crude protein, crude lipid, ash and amylose contents of the red rice flour samples were 5.3, 9.5, 2.0, 1.1 and 4.7%, respectively. The pasting properties of the non-waxy rice flour mixtures to which red rice flour samples were added were measured by RVA. As the content of red rice flour increased, the values of peak viscosity, final viscosity, breakdown and setback were decreased, while the pasting temperature was not significantly affected. The lightness (L) value of the Backsulgi decreased, but the redness (a) value, moisture content and the degree of gelatinization increased with an increase in the red rice flour samples. The hardness increased, while cohesiveness, springiness and chewiness decreased with the increase in the red rice flour. The overall acceptance of sensory evaluation showed the highest value for 8% red rice (BRWM8). In conclusion, the addition of 8% red rice flours could improve the sensory quality of the Backsulgi as well retrogradations.
