  • Retort pouch 식품의 가열살균에 관한 연구의 일환으로 軍用(군용) 및 야외휴대용(野外携帶用)으로의 활용이 크게 기대되는 미반(米飯)에 대해 미생물학적으로 안전하면서 품질의 손실을 최소로 할 수 있는 적정 가열살균조건을 수증기 공기 혼합계(系) 가견수냉식(加堅水冷式) 살균장치를 이용하여 검토하였다. 두께 $15{\sim}25mm$인 retort pouch 미반(米飯)에 대해 열처리온도 $110{\sim}120^{\circ}C$범위에서 열침투시험을 행한 결과 수증기비(比) 65%이상에서는 열전달속도는 수증기비(比)의 영향을 받지 않았으며 $j_h$값은 $1.11{\sim}1.17$로 두께에 관계없이 거의 일정한 값을 보였고 $f_t$값은 두께에 따라 증가하여 $12.0{\sim}16.5$분이었다. 미생물학적으로 안전한 retort pouch 미반(米飯)의 살균조건은 장기 저장시험결과 $F_0$6.0이상인 것으로 나타났다. 열처리 공정의 C값 및 살균한 미반(米飯)의 가열변색을 검토한 결과 최적 품질보유가 가능한 온도-시간조건은 시료두께 15mm의 경우 $120^{\circ}C$에서 승온 및 하강시간을 포함한 38분이였다.

  • This study was investigated to obtain basic data which can be applied to processing of retort pouched seasoned sea mussel. Shell was washed and steamed before shucking. Sea mussel meat was seasoned in boiled and mixed seasoning sauce(soy sauce 23%, monosodiun glutamate 2%, sorbitol 2%, sesame oil 1%, vinegar 2%, starch syrup 15%, water 55%) for 30 min. The seasoned sea mussel was vacuum packed in plastic film bag and sterilized for various Fo values(Fo 7~13 min.) in a hot water circulation system retort at $121^{\circ}C$. The chemical composition such as pH, VBN, amino-N, total amino acid, free amino acid, color value (L, a, b), texture profile, TBA value, mineral, sensory evaluation and viable cells count of the retort pouched seasoned sea mussels sterilized with various conditions(Fo 7~13 min.) were measured. The same experimental items were also measured during storage. There was no remarkable difference between sterilization conditions and sensual characteristics. The results showed that the product sterilized at Fo 7 min. was the most desirable because this condition is most economical.

  • This study presents the effects of serum lipids and blood glucose on retort Samgyetang intake in rats. For this purpose, we measured the ingredients and contents of Samgyetang, and produced a diet for experimental rats. The animal experiment was done in three different diet groups: control, Samgyetang(I) and Samgyetang(II). The results were as follows; 1) There was no sign of difference between the three groups in the body weight gain and food intake due to the effect of dietary component. 2) The density of serum triglyceride in the Samgyetang(II) group was decreased, but there was no sign of difference between the control group and Samgyetang(II). 3) There were no statistically significant differences of serum cholesterol and phospholipid among my of the diet groups. 4) The free fatty acid density and blood glucose level in the Samgyetang(I) and (II) groups were higher than in the control group. In the author's opinion, it is necessary to reexamine them for a long period through the animal experiment.

  • The aim of this research is to evaluate the effects of cooking time and storage temperature on the quality of home-made retort pouch packed Chuncheon Dakgalbi. The leg meat of broiler is being cut into cubes and is mixed with the Dakgalbi sauce and vegetables. Around 200 g of Chuncheon Dakgalbi is being stuffed into a retort pouch and then vacuumed. The retort pouch packed Chuncheon Dakgalbi is subjected to cooking (autoclaving) at $110^{\circ}C$ and 0.75 Kgf for 10, 20 or 30 min and then transferred to the chilling room at $2^{\circ}C$ for rapid cooling procedures. Subsequently, the samples are stored at $4^{\circ}C$ or $25^{\circ}C$ for 4 wk. According to results of sensory evaluation, the highest sensory scores were found in Chuncheon Dakgalbi which was cooked for 30 min (p<0.05). Prolonged cooking time tends to decrease the pH, CIE $L^*$ and CIE $a^*$ levels, and slightly promote the lipid oxidation and protein deterioration. The Chuncheon Dakgalbi being cooked for 10 min promoted the lipid oxidation and protein deterioration during storage at $25^{\circ}C$. Moreover, the total aerobic and anaerobic bacteria in Chuncheon Dakgalbi being cooked for 10 min started to grow after 3 wk of storage at $25^{\circ}C$. Cooking (autoclaving) at $110^{\circ}C$ for 30 min is able to maintain the quality and shelf-life of retort pouch packed Chuncheon Dakgalbion the market.

  • The aim of this study was to develop retorted samgyetang marinated with different levels of soy sauce and processed at different F0 (thermal death time at 121℃) values. The tested marinade series comprised different percentages of soy sauce in water (0%, 25%, and 50% [w/w]) containing a fixed concentration of sodium tripolyphosphate (0.3% [w/w]). Following marination, samgyetang was prepared and subjected to retort processing, until an F0 value of either 8 or 29 was achieved. Meat quality analysis of the breast meat, sensory evaluation, and aroma analysis were performed as indicators of acceptability. The meat pH decreased as the soy sauce content increased, regardless of the F0 value. The shear force value significantly decreased as the concentration of soy sauce increased, but increased as the F0 value increased (p < 0.05). Lipid oxidation was not affected by marination, but increased significantly as the F0 value increased (p < 0.05). The proportion of polyunsaturated fatty acids decreased significantly (p < 0.05) as the F0 value increased. The total alkane content decreased as the F0 value increased (p < 0.05). Changes in the total volatile sulfur compound and 2-butyl-1-octanol content were affected by soy sauce marination. Marination using 25% soy sauce and retort sterilization, until an F0 value of either 8 or 29 was achieved, improved the acceptability of samgyetang. Therefore, marination using 25% soy sauce and retort sterilization until an F0 value of 8 is the process recommended for developing a soy sauce-flavored, retorted samgyetang product of acceptable quality.

  • This study was conducted to investigate the food components of cooking drips from shell oysters steamed under various retort pressures. Among the drips from shell oyster steamed under different retort pressures (1.0, 2.0, 2.5, 3.0, 3.5, 4.0 and 4.5 kg/$cm^2$) the oyster drip obtained at the 4.5 kg/$cm^2$ of retort pressure had the highest degree of brix, yield, crude protein, glycogen and trichloroacetic acid soluble-N contents, while its salinity was the lowest. In the results of food safety test, the presence of E. coli (18 MPN/100 g>) and viable cell (30 CFU/g>) in the oyster drip was in acceptable level as a food-stuff. However, the sensory evaluation such as color, flavor and taste, total amino acid and free amino acid contents of cooking drip from shell oyster steamed at 4.5 kg/$cm^2$ were inferior to those of oyster wash water. Differences in the major amino acids of total amino acid and free amino acid between oyster cooking drip and oyster wash water were also found. The results suggested that the effective use methods of oyster cooking drip should be investigated.
