Study on Bread-Making Quality with Mixture of Buckwheat-Wheat Flour

메밀가루를 이용한 제빵적성 연구

The possibility of buckwheat-wheat flour mixture as bread was studied by adding 10, 20, and 30% of buckwheat to wheat flour. To improve bread-making quality of the mixture, gluten, ascorbic acid, and hydroxy propyl methyl cellulose (HPMC) were added to 30% buckwheat-wheat flour and sensory evaluation was also exercised on it. The weight of bread increased but the volume of that decreased as the percentage of buckwheat to wheat flour increased, and improved bread-making quality by adding gluten, ascorbic acid, HPMC to 30% buckwheat-wheat composite flour. When it comes to color, color of the bread got darker as the percentage of buckwheat increased, got brighter when gluten and HPMC were added and showed little difference when ascorbic acid was added. Texture of bread increased in maximum weight, strength, hardness but decreased in springiness and cohesiveness. The use of additives showed influence to the some results. In terms of the aging process, enthalpy increased with storage time, and it could be slowed down by the use of the additives. The sensory evaluation shwoed that 10% buckwheat-wheat bread was most excellent, 20% bread was similar to other bread made from wheat flour, and the bread made by mixing additives were better than just 30% buckwheat-wheat flour in terms of quality.
