  • This study was attempted to enhance the contents of dietary fiber and minerals of cooked rice by adding four different levels of carrot juice in cooking water (0%:A. 10%:B. 20%:C. 30%:D). The degree of gelatinization and retrogradation, sensory evaluation. and in vitro digestion ratio were tested. These results concluded that the rice cooked with 10~20 % of carrot juice in cooking water was quite acceptable. the optimum cooking conditions fur the rice were one hour presoaking time, 160% cooking water to rice ratio. 20 minutes heating time and 10 minutes steamed cooking.

  • This study was conducted to investigate the changes of mineral contents in radish leaves, soybean sprout and chwi namul by cooking method(boiling, steaming, sauting) and cooking time(1, 3, 5 min.). The residual rate of minerals(such as Calcium, Sodium, Potassium, Iron and Magnesium) in radish leaves, soybean sprout and chwi namul by 1 minute sauting was the range of 83.2 to 99.1%. It was shown that sauting was desirable method for all three vegetables. The residual rate by the cooking method was sauting, steaming, boiling, in that order, but boiling in radish leaves and chwi namul were more desirable method than steaming for Calcium use. At the cooking method and cooking time, Potassium content in soybean sprout was reduced remarkably in 5 minutes boiling. Boiling of radish leaves and soybean sprout showed that Sodium was reduced remarkably after 5 minutes of boiling, 54.4% for radish leaves and 19.9% for soybean sprout, respectively.

  • Codonopsis lanceolata serves as, an appetizing health food for its, characteristic flavor, taste, and texture:however, it requires a long and complicated cooking process. Therefore, this study conducted pre-processing procedures to improve the cooking process and Codonopsis lanceolata more easily. For processing efficiency, freezing and blanching were efficient for peeling and the rate of peel disuse. In addition the freezing process, effectively reduced the time spent in beating raw material. In the salinity test, freezing and blanching quickly increased salinity over 28 days. As the result of SEM cross-section tests showed that frozen Codonopsis lanceolata become porous, it's assumed that seasoning permeates into this cross-section efficiently. As the appearance of Deodeok-gui as significant differences according to the pre-processing methods, this study examined pre-processing methods(time spent in peeling, rate of peel disuse, time spent in beating out material, salinity, moisture content, texture, and the color) of Codonopsis lanceolata. After testing Deodeok-gui, it was found that freezing is effective, not only for process efficiency and cooking time reduction, but also for improving its qualities.

  • 밀국수와 냉면국수의 삶음 시간과 삶은후 저장시간에 따른 조직감의 변화를 관능검사에 의하여 평가하고 국수의 굳기(hardness), 씹힘성(chewiness) 및 기호도와 creep test에서 얻은 기계적 모델 상수와의 상관관계를 시험 하였다. 국수의 굳기는 삶음 시간에 민감하게 영향을 받았으며 삶은후 저장시간이 경과함에 따라 다소 연화되는 경향을 나타내었다. 씹힘성은 삶음 시간과 저장시간에 거의 같은 정도로 감소됨을 나타내었다. 국수의 기호도는 밀국수의 경우 삶음시간에 크게 영향받지 않았으나 냉면국수는 삶음 시간이 경과함에 따라 기호도가 크게 감소하였다. Creep test에서 측정되는 순간탄성이 크면 클수록 국수는 굳기가 감소되는 관계를 나타내었다. 밀국수의 조직감 및 기호도는 Creep test의 탄성요소 및 점성요소와 유의적인 상관관계를 나타내었으며 냉면국수는 지연시간과 유의적 상관관계가 있음을 관찰하였다.

  • The effects of cooking methods and storage time on folate content in spinach were determined by boiling for 1, 2, 3, 4, 5, 10 and 20min in distilled water or by microwave blanching for 20, 40, 60, 80, 100 sec. The folate content of cooked spinach was decreased to 80.7% after 1min boiling, and to 5.5% after 20min boiling. The folate recovered from the cooked spinach and cooking water was 101.1% after 1min, 68.0% after 2min and 51.3% after 3min. The relative folate content leached out of the cooked spinach into the cooking water varied from 20.2% after 1min boiling to 88.8% after 20min boiling. Total folate content of spinach was decreased to 45% by microwave heating for 40sec. However, the spinach cooked by microwave heating retained more folate due to the minimal loss of folate into cooking water. More than 90% of folate content of spinach was retained during 1 to 2 weeks of storage at 4$^{\circ}C$.

  • Objective: This study aimed to elucidate whether innovative sous vide treatment has a significant influence on the beef semitendinosus muscle as compared to common sous vide treatment and traditional cooking. Methods: The innovative sous vide treatments were cooked at $45^{\circ}C$ and $65^{\circ}C$ for 6 h (SV45-65), common sous vide treatment at $45^{\circ}C$ and $65^{\circ}C$ for 3 h (SV45 and SV65) and traditional cooking at $75^{\circ}C$ for 30 min (CON75). Water loss and cooking loss, as well as the physical properties (color and shear force) and chemical properties (protein and collagen solubility) of the treated meat, were investigated. Results: The results obtained indicated that the innovative sous vide with double thermal treatment (SV45-65) and cooked with air presence (CON75) resulted to lower $a^*$ and higher $b^*$ values, respectively. The water loss and cooking loss increased when temperature increased from $45^{\circ}C$ to $65^{\circ}C$, and lower water loss was recorded in SV45 and CON75. These samples presented higher water content and revealed strong correlation to protein solubility. Warner-Bratzler shear force (SF) analysis showed the marked interaction between cooking temperature and time. Sample cooked at a high temperature (CON75) and a long period (SV45-65) showed a significantly lower value of SF than sample SV65 (p<0.05). Interestingly, there was no difference in SF values between SV45-65 and CON75. Conclusion: The innovative sous vide treatment with double thermal effect appears an attractive cooking method as compared to common sous vide and traditional cooking method, as it has a potential for improving tenderness values of cooked beef semitendinosus muscle.

  • The autoclave method and the traditional cooking method were compared for nutrients(especially, minerals), color difference, viscosity, reduction of sugar and amino nitrogen content of brown stock. The autoclave cooking method is better than the traditional cooking method for retaining protein and amino nitrogen contents, as well as for reducing sugar content. Also, reducing sugar content increased by the autoclave cooking method. Since the color of brown sauce was related with the reducing sugar content, the autoclave cooking method was more effective than the traditional cooking method for the color development of brown stock. Since the autoclave method can reduce the cooking time without a loss of quality in brown stock, the autoclave method is a viable alternative to the traditional method of preparing brown stock.

  • The goal of this study was to determine whether food industry workers are exposed to musculoskeletal loads due to the work time, frequency, awkward postures and inappropriate workspace design. Three catering workers were evaluated based on job analysis and posture analysis. The results showed that the four most time-consuming tasks were arranging(17%), cooking(16%), handling before cooking(15%) and cutting(15%), and the four most frequent tasks were arranging(21%), cooking(18%), handling after cooking(16%) and handling before cooking(13%). The most common posture was a standing posture(73%) with neutral back(73%), and bent head(50%), left lower arm(71%), right lower arm(78%) and right hand(60%). The comparative analysis of subtasks for the risk levels of musculoskeletal disorders was conducted using the work time, frequency and cumulative time of the postures. The 'displaying' and 'handling after cooking' showed higher risk levels than other subtasks. In addition, the height and length of the tables were evaluated to be inadequate for the workers. It can be concluded that the working environments for catering workers of restaurants should be improved due to the high cumulative time of awkward postures of upper extremities.
