The effects of gamma irradiation to improve the hygienic quality and microbiological shelf stability of whole baked egg were investigated by comparison with autoclaving process. The contamination levels of coliform, total aerobic bacteria and fungal group in a fresh egg were 10$^{5}$ CFU/g, 10$^{2}$ CFU/g and 10$^{1}$ CFU/g, respectively. After baking process, total aerobic bacteria and fungi were not exceeded to 10$^{1}$ CFU/g. Also, coliform was not detected under the aseptic process. However, cell counts of the baked egg after packaging reached to 10$^{4}$ CFU/g of total aerobic bacteria, 10$^{1}$ CFU/g of coliform, and 10$^{2}$ CFU/g of fungi. Therefore, it was assumed that microbial contamination of baked and packaged egg was mainly originated from an environmental uptake during packaging process. Microbiological shelf stability of the non sterilized control was about a week. Whereas, the baked eggs irradiated at more than 5 kGy were stable over 12 weeks at ambient condition as like those being autoclaved. Analytical texture profIle was stable within 10 kGy, but it became hardened in the sample treated with autoclaving. About 67$\%$ of panelists identified a sensory difference between non-irradiated and 10 kGy-irradiated sample. The baked egg irradiated at 10 kGy and autoclaved had lower acceptability than the control or samples irradiated lower than 5 kGy. Therefore, it was considered that optimal irradiation dose for radiation sterilization of baked and packaged egg was 5 kGy. At that point, it was recommended that appropriate microbiological shelf-life was 12 weeks at ambient condition.

This study was conducted to investigate the effect of heating temperature and time on the quality of baked egg. Eggs were baked at various temperatures (80, 90, 100, 105 and $110^{\circ}C$) for different times (5, 6, 7 and 8 h) using a commercial heater. Our results revealed that heating loss in the $110^{\circ}C$ treatment was significantly (p<0.05) higher than those of other remaining treatments. The pH value of egg white in the 5 h treatment was significantly (p<0.05) higher compared to those of other treatments. While, no significant differences in pH values of egg yolks occurred among the treatments. Regarding the texture, hardness and cohesiveness values were not significantly different among the treatments. Regarding color, the $110^{\circ}C$ treatment samples had lower lightness value whereas had higher redness and yellowness values compared to the $105^{\circ}C$ treatments (p<0.05). Moisture content of baked eggs showed an decreased tendency as increasing the heating temperature and time. These results suggested that the proper conditions were 8 hours for total baking time including more than 5 h at $105^{\circ}C$ or 2 h at $110^{\circ}C$.

최근 중국으로부터 구운계란이 수입되어 원산지 표시가 되지 않은 채 국내 시장을 잠식하고 있어 계란가공업계가 긴장하고 있는 가운데, 계란 가공산업에 뛰어들어 소비확대에 앞장서고 있는 난가공업체들의 피해가 우려되고 있는 실정이다. 국내 난가공소비 비율은 전체 계란 소비의 $15\%$를 차지하고 있으며, 이는 일본 $60\%$, 유럽 $30\%$에 비해 크게 뒤져있는 실정이다. 과거부터 많은 업체들이 계란가공 산업에 뛰어들어 소비확대를 꾀했으나 맛과 안전성, 유통, 소비 분야에 충족하지 못하고 실패를 거듭해왔다. 또한 가공원료로 사용되는 난황분, 난백분 등은 단가면에서 외국산과 경쟁력을 잃어 수입산물로 대체되면서 가공란 산업의 저해요인으로 작용하고 있다. 더욱이 최근 식품에 대한 위생문제가 크게 부각되고 있는 가운데 기존의 가공란 업계도 소비자를 배제할 수는 없는 시대에 돌입하게 되었다. 이런 어려운 여건속에서 국내 난가공 산업의 발전과 활로를 찾기 위해 농업회사법인 충의(주)(대표 조규석)가 기존의 난가공 마인드를 깨고 맛과 안전성에 초점을 맞춰 신상품개발로 소비자들로부터 큰 호응을 불러오면서 큰 기대를 모으고 있다.

Olive flounder contains rich amount of lysine which is required for children's growth. Moreover, it is good foodstuffs for elderly, convalescent and diabetics because of low lipid content and high digestibility. This study was investigated for the purpose of obtaining basic data which can be applied to the processing of olive flounder steak. Olive flounder 100 g were chopped, mixed with vegetable (onion 20%, celery 10%, carrot 15%, garlic 1% of chopped olive flounder meat) and ingredient (bread crumbs 20 g, onion 15 g, celery 10 g, egg 1 ea, tarragon 1/2 t, blanc sauce 20 g, fresh cream 20 mL, salt and pepper pinch). Mixed dough was molded into steak shape ($12{\times}7cm$) and was processed by two types of products, Steak-1 {Roasting for 2 minutes in a frying pan wrapped with olive oil and then vacuum packaging in polyethylene film ($20{\times}30{\times}0.05mm$), and then storage at $-20^{\circ}C$ for 7 days, next thawed and warmed by microwave for 2 minutes} and Steak-2 {vacuum-packaging in polyethylene film ($20{\times}30{\times}0.05mm$), and then storage at $-20^{\circ}C$ for 7 days, after thawed, roasted during 2 minutes in a frying pan wrapped with olive oil}. The factors such as pH, TBA value, amino-N, free amino acid, chemical composition, color value (L, a, b), texture profile, sensory evaluation and viable bacterial count of the olive flounder steak (Steak-1, Steak-2) were measured. From the result of sensory evaluation, Steak-2 showed a bit more high scores than Steak-1 but it was difficult to distinguish significant difference (color, odor, taste, texture and acceptance) between Steak-1 and Steak-2 products.
