Abstract

This study assessed the technology to minimize the discoloration to reduce the defect rate and penetrate the curing solution through the egg shells to produce quality smoked eggs that meet the preference of consumers. The discoloration refers to the defects on the colors of egg shells due to overheated smoking fluids, causing the eggs to be discarded. The manufacturing process was prepared by the manufacturer of the regular smoked egg manufacturing process. A preliminary study found that the preferred salinity of smoked eggs was 1.67~2.00% and the major processing factors have been set to maintain the optimal salinity of smoked eggs and an industrially attainable minimum defect rate below 3%. When the eggs were aged at $50^{\circ}C$ for 96 hours to produce the smoked eggs, the discoloration rate was 0%. When the circulatory dipping method was applied, 3.00% salinity was achieved after 8 hours. When the eggs were smoked at that time, the salinity was 1.67%. With a $2.07kg/cm^2$ pressure, 3.33% salinity was achieved after 4 hours and 2.00% salinity was achieved when the smoked eggs were produced. To identify the most efficient pressurizing method, 0.52, 1.55, 1.86, 2.07, 2.38, 2.58, and $3.62kg/cm^2$ were applied, the discoloration rate was 2.2% after 4 hours under a $2.07kg/cm^2$ pressure. The aging and pressurized method is considered to be the basis for reducing the manufacturing time and decreasing the rate of error during the smoked eggs process.

본 연구는 훈제 계란의 제조시간 단축과 진의 생성으로 발생하는 불량 훈제 계란을 감소시키기 위한 공정 조건 설정을 위한 목적으로 실시하였다. 진은 공정과정 중에 염지액의 과열 등으로 발생하는 난각의 얼룩으로 훈제 계란의 난각에 진이 발생할 경우 상품으로 사용할 수 없어 불량 처리하고 있다. 본 실험에 사용된 재료인 계란은 부산 오경농장에서 구입하여 대란만을 사용하였다. 제조 공정은 일반적인 훈제 계란 가공업체의 제조 공정을 참고로 작성하였다. 예비 실험을 통하여 훈제 계란의 최적 염도는 1.67~2.00%이었고, 훈제 계란의 진 발생으로 생성되는 불량 계란은 5%로 최적 염도의 조건과 3% 미만의 불량률을 목표로 하였다. 숙성 공정의 $50^{\circ}C$에서 96시간 숙성한 후, 훈제 계란을 가공하였을 때 진 발생은 0%였다. 순환식 침지방식은 8시간 처리하였을 때 제조한 훈제 계란의 염도는 1.67%였으며, 가압 방식은 $2.07kg/cm^2$의 압력으로 4시간 처리하였을 때 제조한 훈제 계란의 염도는 2.00%였다. 최적 효율의 압력을 찾기 위하여 0.52, 1.55, 1.86, 2.07, 2.38, 2.58, $3.62kg/cm^2$으로 처리하였을 때 $2.07kg/cm^2$의 압력 처리가 최적의 훈제 계란 염도와 2.2%의 진 발생률을 보였다. 숙성 및 가압 방식은 훈제 계란 가공 시 제조시간의 단축과 불량률을 감소시켜 줄 수 있는 기초가 될 것으로 사료된다.
