밀가루의 단백질 함량이 라면의 품질에 미치는 영향

Effects of Wheat Flour Protein Contents on Ramyon (deep-fried instant noodle) Quality

단백질 함량이 9.12-9.78%인 HRW-WW와 DNS-WW 밀가루를 이용하여 상업적으로 제조한 라면의 품질을 평가하였다. 조리된 라면의 무게와 부피는 일정한 조리시간에서 단백질 함량이 증가할 수록 감소하였다. 단백질 함량에 따른 HRW-WW와 DNS-WW 라면의 조리 성질은 서로 유의적인 차이가 없었다. 라면을 4분 조리한 후 무게와 부피는 HRW-WW의 경우 파리노그라프와 익스텐소그라프의 지표와는 유의적인 부의 상관을, 아밀로그라프의 지표와는 유의적인 정의 상관을 보였으나, DNS-WW의 경우에는 상관관계를 보이지 않았다. 라면의 관능검사 결과 적정 단백질 함량은 9.28-9.62%이었고 HRW를 DNS로의 대체 효과는 없었다.

The quality of Ramyon prepared from hard red winter-western white (HRW-WW) and dark northern spring-western white (DNS-WW) flour blends having protein contents of 9.12-9.78% was examined. The noodles were manufactured by commercial process with the same water absorption. The weight and volume of cooked noodle were decreased as the protein content increased at the same cooking time. No significant differences in cooking properties were observed between noodles prepared from HRW-WW and DNS-WW blends. The weight and volume of noodle prepared from HRW-WW blend cooked for 4 min showed significant negative correlation with farinograph and extensograph data and protein contents of flours, but positive correlation with amylograph data. Such correlations were not found from noodles prepared from DNS-WW blend. Based on the sensory evaluation of cooked noodle it was concluded that the optimum protein content for noodle manufacture was in the range of 9.28-9.62%. The replacement of HRW with DNS flour had no effect on the sensory quality of noodle.
