초록

본 연구는 난각의 손상 없이 조미액 가압침투 방법을 이용하여 편리하게 식용할 수 있는 훈제 계란을 개발하고, 제품의 품질 특성에 대하여 연구하였다. 동결 건조된 훈제 계란의 일반성분의 경우 수분 2.43%, 조회분 4.11%, 조단백질 46.08%, 조지방 40.85%, 탄수화물은 6.53%이었으며, 총 폴리페놀 함량은 3.11 mg%, 총 포화지방산의 함량은 35.70%, 불포화지방산은 64.30%로 나타났다. 주요 포화지방산으로 Palmitic acid(C16:0), Stearic acid(C18:0), Lauric acid(C12:0) 이었고, 주요 불포화지방산으로는 Oleic aicd(C18:1), Linoleic aicd(C18:2)로 나타났다. 색도는 훈제 계란은 훈연에 의해 난각의 색이 매우 짙은 갈색이었고, 난백, 난황, 난각은 삶은 계란에 비해 어둡게 나타났으며, a(redness)값은 훈제 계란이 높게 나타났다. 훈제 계란은 삶은 계란에 비해 관능적으로 매우 우수하게 나타났다. 이는 조미액과 훈연향에 의해 선호도가 높아졌다고 판단된다. 본 연구 결과는 난각의 손상 없이 조미액이 침투된 훈제 계란을 제조하는 방법과 그 품질 특성을 연구함으로써 국내 계란을 이용한 가공식품 개발과 난 가공 산업의 발전에 영향을 줄 수 있을 것으로 생각된다.

This study was conducted to develop an edible smoked egg by penetrating seasoning through pressurization without damaging the eggshell and to investigate the quality characteristics of the product. The lyophilized smoked egg consisted of 2.43% moisture, 4.11% crude ash, 46.08% crude protein, 40.85% crude fat and 6.53% hydrated carbon. The total content of polyphenol was 3.11 mg%, 35.70% saturated fatty acid and 64.30% unsaturated fatty acid. Major types of saturated fatty acids included palmitic acid (C16:0), stearic acid (C18:0) and lauric acid (C12:0), while major unsaturated fatty acids included oleic acid (C18:1) and linoleic acid (C18:2). Due to smoking of the egg, the eggshell is dark brown, the egg albumen, egg yolk and egg shell are darker than boiled eggs, and the value of a (redness) is higher than that of boiled eggs. Overall, smoked eggs were organically superior than boiled eggs because of their seasoning and smoke flavor. The results of this study are expected to further the development of processed foods using domestic eggs and improve the egg processing industry.
