Abstract

To utilize the small redlip croaker, four kinds of seasoned fillet were produced. The nutrient composition, peroxide value and coliforms count of the products were determined, and sensory characteristics were evaluated. The seasonings consisted of the formula for commercial dried file fish added with water (A, control), green tea extract (B), rosemary extract (C) and soypaste with red pepper (D). The crude protein and carbohydrate contents of the products were in the range of 39~45% and 23~3l%, respectively. The lipid content of product B was the lowest, while that of product D was the highest among the tested products. All products showed similar amino acid profiles with a high content of glutamic acid, aspartic acid, glycine and lysine. The saturates in fatty acid composition were similar (50~51%) among the products. However, the polyenes were higher (17%) in product C than products A, B and D (13%). The peroxide value of product C was the lowest among the products. There were not significant differences in taste and color among the products.

본 연구는 참조기를 이용하여 조미액을 달리 하여 4가지 건포류를 제조한 후 영양성분, 과산화물가, 대장균군수 및 관능평가를 실시한 결과 다음과 같은 결과를 얻었다. 건포류의 일반성분에서 수분은 다른 제품에 비해 녹차액을 사용한 B제품이 약간 높게 나타났으며, 조미 건포류의 단백질함량은 39~45%로 대체로 높게 나타났다. 지방함량은 녹차액이 함유된 B제품이 가장 낮았으며, 매운 조미료를 이용한 D제품에서 지방함량이 가장 높게 나타났다. 탄수화물 함량은 23~31%로 나타났으며 , 매운맛을 내는 D제품의 탄수화물 함량이 가장 낮게 나타났다 회분 함량은 특히 매운 조미료를 사용한 D제품에서 다른 제품보다 약간 높게 나타났다. 건포류의 구성 아미노산 중 함량이 가장 높은 것은 glutamic acid이었으며, 다음으로 aspartic acid, glycine, lysine 순으로 나타났다. 지방산의 구성에서 포화지방산의 비율은 50~51%범위로 거의 제품간의 차이가 나타나지 않았고, monoenes의 비율은 로즈마리액을 처리한 제품의 비율이 가장 낮았으며, polyenes의 비율은 상대적으로 로즈마리액을 처리한 제품이 높게 나타났다. 과산화물가가 가장 낮은 제품은 로즈마리액을 첨가한 C제품이었으며, 매운맛을 내는 D제품이 가장 높은 값을 나타냈다. 대장균군수는 모든 제품에서 모두 음성으로 검출되지 않았다 관능평가결과 맛, 색의 경우 모든 제품이 쥐포와 유의적인 차이가 없었으며, 냄새의 경우 매운맛을 내는 D제품은 쥐포와 차이가 없었으나, A, B, C제품은 모두 쥐포에 비해 유의적으로 낮게 나타났다. 전반적인 좋아함에서는 모든 제품이 쥐포와 차이가 없었다.
