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.
