Abstract

To develop a new quality control method for the evaluation of Korean instant noodle soups, the chemical characteristics of roasted red pepper powder (RRP), mixed with lard were investigated while in storage at $65^{\circ}C$ for 6 weeks. The moisture contents of the RRP increased but the crude protein and crude lipid contents decreased up to 4 weeks of storage. The pH value decreased and the acid value increased steadily during storage. Both the American Spice Trade Association (ASTA) value that indicates redness of red pepper, and the CIE L, a, and b values decreased remarkably during storage. The fatty acids of the RRP oil were primarily oleic acid (33.4%), linoleic acid (30.8%), and palmitic acid (21.2%). The composition of fatty acids did not significantly change after 6 weeks of storage (p>0.05). Regarding the free fatty acid (FFA) composition of the RRP oil, palmitic acid (36.5%) was the principal component. The total amount of FFA and the amount of each individual FFA increased remarkably during storage. In addition, the ratio of free unsaturated fatty acids to free saturated fatty acids increased during storage.

라면 수프의 품질 안정화 기술을 개발하기 위하여, 라면 수프의 주원료인 돈지가 첨가된 조제고춧가루를 $65^{\circ}C$에서 6주간 저장하면서 화학적 특성 변화를 조사하였다. 저장 4주까지 수분양은 증가하였으나, 조단백질과 조지질 함량은 감소하였다. pH는 지속적으로 간소하였으며, 시료로부터 추출한 지질의 산가는 저장기간이 길어짐에 따라 증가하였다. ASTA 값과 CIE L값, CIE a값 그리고 CIE b값 모두 저장기간이 길어짐에 따라 크게 감소하였다. 시료로부터 추출한 지질을 구성하는 지방산은 9종류가 확인되었는데, 이들 중 불포화지방산인 oleic acid(18:1)가 33% 이상으로 가장 높은 수준이었으며 저장기간이 증가함에 따른 지방산 조성의 변화는 나타나지 않았다(p>0.05). 시료로부터 추출한 지질에 가장 많이 존재하는 유리지방산은 palmitic acid(16:0)이었고, 저장기간이 길어짐에 따라 유리지방산의 총량이 크게 증가하였을 뿐만 아니라 모든 유리지방산의 함량도 크게 증가하였으며, 유리 불포화지방산과 유리 포화지방산의 비율은 저장기간이 증가할수록 증가하였다.
