초록

본 논문은 rye bread 제조에 있어서, water, rye flour 그리고 vital gluten이 rye bread의 관능 특성에 미치는 영향에 대하여 response surface methodology, 관능검사 및 통계적 분석을 통하여 연구하였다. Response surface model은 rye bread의 최적 variation을 결정하고 관찰되어진 결과를 평가하기 위하여 사용되었으며, 본 실험은 water 57, 62, 67%, rye flour 0, 10, 30, 50% 그리고 vital gluten 0, 1, 3, 5%의 12가지 조합을 하여 실험하였다. 실험 결과 water 67%, rye flour 10% 그리고 vital gluten 3%일 때 높은 specific volume의 rye bread가 생산되었으며, water 62%, rye flour 10%그리고 vital 히uten 5%일 때 전체적인 관능치가 높은 rye bread가 생산되었다. 또한 specific volume과 전체적인 기호도도 높은 것으로 나타났으며, 이러한 결과는 bread loaf volume과 소비자의 기호도가 직접적인 관계가 있음을 보여준다. 본 논문은 rye bread의 생산에서 다양한 water, rye flour그리고 vital gluten의 배합에 대한 정보를 제시하였으며, 표준화 최적화 방법에 대한 기초 정보를 제공하는데 큰 의의를 두었다. 또한 이 결과는 water, rye flour 그리고 vital gluten이 rye bread의 생산에서 다양한 방법으로 배합될 수 있으며, 제빵의 기능적 특성을 최적화 하는데 기여할 것으로 기대된다.

The effects of water, rye flour and vital gluten on the sensory properties of bread were studied by response surface methodology and sensory evaluations. A response surface model was used to evaluate the effects observed and to determine the optimum variations for rye bread. The study included 12 combinations of the following independent variables: Water(57, 62, 67%), Rye flour(0, 10, 30, 50%), and Vital gluten(0, 1, 3, 5%). Bread quality attributes determined were specific volume, color, texture, appearance, taste, chewiness, moisture, overall. Rye bread specific volume, sensory evaluation values and Instrumental testing results were significantly affected by variety (water, rye flour and vital gluten). Rye bread with a high specific volume was produced using water 67%, rye flour 10% and vital gluten 3%. Whereas, rye breads with a high overall sensory evaluation were water 62 %, rye flour 10 % and vital gluten 5%. And Specific volume predicted and overall preference also was shown high. It was shown that the experimental design used provided information about the rye bread of variation of water, rye flour and vital gluten and can be a useful supplement to standardized and optimized formulas in rye bread making. The results suggest that water, rye flour, vital gluten can be combined in rye bread making at various levels, contributing to optimize the functional properties of rye bread. These result represents that breads loaf volume related to directly consumer preference.
