유색미(수원 415호) 가루의 제빵성 검토 = Studies on Bread-Making Quality of Colored Rice ( Suwon 415 ) Flours

국문 초록 (Abstract)

유색미 수원 415호 쌀가루에 gluten 대체재료로써 10% gluten 및 3% hydroxypropyl methyl cellulose를 첨가하여 제조한 쌀빵의 가공적성을 검토한 결과, 유색미 수원 415호로 성형성이 아주 좋은 쌀빵의 제조가 가능하였다.
유색미 쌀빵의 물성 중 경도와 씹힘성은 3% hydroxypropyl methyl cellulose를 첨가하여 제조한 것이 10% gluten을 첨가하여 제조한 것 보다 낮아 부드러웠으며, 탄력성은 이와 반대의 경향을 나타냈었다.
또한 저장에 따른 쌀빵의 노화도는 3% hydroxypropyl methyl cellulose 첨가하여 제조하는 경우 강력분으로 제조한 빵과 비슷한 수준이었다.
관능검사 결과에 의하면, 3% hydroxypropyl methyl cellulose를 첨가하여 제조한 쌀빵은 밀가루 빵에 비해서 질감이 부드럽기는 하지만 기공의 균일성은 나쁘게 나타났다. 그러나 빵의 탄력성은 밀가루 빵에 비해 유이적인 차이가 없었다.

다국어 초록 (Multilingual Abstract)

Colored rice (Suwon 45) flour was evaluated as a bread flour by the addition of 10% gluten on 3% hydroxypropyl methyl cellulose to check the processing adaptability. Both of these additives led to a successful formation of rice bread. Textural characteristics of colored rice bread crumb baked with 3% hydroxypropyl methyl cellulose revealed lower hardness and chewiness, however, the one with 10% gluten revealed the higher springiness. The retrogradation of colored rice bread during storage was not significantly different from that of wheat bread. Sensory evaluation showed that the crumb texture of bread baked with 3% hydroxypropyl methyl cellulose had softer texture and poor distribution of air-pore size but its springiness was not significantly different from that of wheat bread.
