가공쌀분말을 이용한 글루텐프리 쌀빵 제조 방법의 최적화

국문 초록 (Abstract)

가공쌀분말의 첨가량과 수분함량을 달리한 글루텐프리 쌀빵 제조 최적 조건을 반응표면분석법의 중심합성계획법을 이용하여 확인하였다. 가공쌀분말의 첨가량과 수분함량을 달리한 글루텐프리 쌀빵 반죽의 발효 팽창력에 대한 반응표면 회귀식에 대한 R²값은 0.6006(P=0.4413)으로 상관성은 낮았다. 글루텐프리 쌀빵의 부피에 대한 반응표면 회귀식 R²값은 0.9376(P=0.0160)으로 반응표면분석에 대한 상관성은 높았으며, 분석 결과 예측된 정상점은 최고점으로 가공쌀분말이 15.14%이고 수분함량이 81.75%일 때 예측되는 최고 부피는 546.526 mL를 나타내었다. 깨짐성에 대한 반응표면 회귀식의 R²값은 0.9664(P=0.0048)로 반응표면분석에 대한 상관성은 높았으며, 예측된 정상점은 최저점으로 가공쌀분말이 18.09%이고 수분함량이 108.27%일 때 최저 깨짐성은 23,070 g을 나타내었다. 경도에 대한 반응표면 회귀식의 R²값은 0.9648(P=0.0052)로 반응표면분석에 대해 상관성은 높았으며 예측된 정상점은 최저점으로 가공쌀분말이 16.09%이고 수분함량이 98.10%일 때 최저 경도는 130.915 g을 나타내었다. 종속변수들을 중첩시켜 구한 최적효과 중첩 부분은 가공쌀분말 13~19%, 수분함량 80~90%인 것으로 나타났다. 결론적으로 가공쌀분말의 첨가량과 수분함량을 달리하여 글루텐프리 쌀빵을 제조할 때 가공쌀분말 함량은 16%이고 수분함량은 85%일 때 최적임을 알 수 있었다.

To investigate the effect of processed rice flour (PRF) and moisture content (MC) on gluten free rice pan bread made with various amounts of PRF, the dough expansion rate, bread volume, bread brittleness, and bread hardness of gluten-free rice pan bread were analyzed by using response surface methodology (RSM). The R² values of the dough expansion rate (DER), bread volume (BV), bread brittleness (BB), and bread hardness (BH) of gluten-free rice pan bread were represented as 0.6006 (P=0.4413), 0.9376 (P=0.0160), 0.9664 (P=0.0048), and 0.9648 (P=0.0052). Since DER was not suitable for RSM analysis due to its low R² value, BV, BB, and BH were analyzed for optimal conditions. The optimum conditions for making gluten-free rice pan bread with various amounts of PRF resulted in maximum BV at 15.14% PRF and 81.75% MC (546.526 mL), minimum BB at 18.09% PRF and 108.27% MC (23,070 g), and minimum BH at 16.09% PRF and 98.10% MC (130.915 g). In the contour map analysis, the contour region was 13∼19% PRF and 80∼90% MC. According to the optimization, 16% PRF and 85% MC showed good fit to the predicted values for making gluten-free rice pan bread.
