In this paper, quality properties and antioxidant capacity of cooked black carrot has been studied. Five different cooking methods have been applied: microwave (45 sec), boiling ($100^{\circ}C$, 14 min), steaming ($100^{\circ}C$, 20 min), sous vide ($75^{\circ}C$, 80 min), sous-vide ($95^{\circ}C$, 30 min). The color value was slightly different (p<0.05), the boiling method was the highest in L-value and Sous vide $75^{\circ}C$ method was the lowest. The steaming method indicated the highest a-value at 5.50. The b-value was significantly different between the samples (p<0.05). The microwave method was the highest at 3.49 while the sous vide $95^{\circ}C$ method was the lowest at -0.34. No significant difference was observed between the samples when only the moisture content results were considered. The highest pH was observed in samples cooked using the boiling method. The softening (%) was higher when the cooking water was in contact with samples and it was dependent on the temperatures. In addition, this study shows that not only temperature but also cooking time and cooking media are very crucial in the preparation and cooking of black carrot to prevent the loss of the antioxidant compound. In conclusion, the comparison of the quality characteristics and antioxidant properties of black carrots indicated that the most appropriate cooking method is sous-vide method.
This study was carried out to investigate the physico-chemical properties of imported beef and Hanwo beef tenderloin steak in proximate composition, pH, myofibril Fragmentation Index (MFI), meat color, cooking loss, rheology and panel test by various cooking methods (grilling, pan-frying, oven-roasting and microwaving). moisture content of microwaving steak was lower than steak by other cooking method, and fat content of microwaving steak was higher than those of other cooking method was showed. In general, the pH values were increased with cooking, but there were no significant differences among pH values by various cooking method. The highest level of MFI in oven-roasting was showed, but no significant difference could be found among various cooking method. L* and b* -values of microwaving and pan-frying were higher than those of grilling and oven-roasting, also a* -value of microwaving was the lowest. Cooking loss was affected by cooking method. Microwaving method resulted in the highest cooking loss. Generally higher value of hardness and brittleness in microwaving than those of other cooking method were showed, and microwaving had the lowest cohesiveness, but there was no significant difference among the elasticity by the cooking method. Grilling, pan-frying and oven-roasting had high score of sensory evaluation, while microwaving had the lowest score in all sensory profile scores.
This study compared and analyzed the structures of cooking recipes in order to identify the overall cooking method and develop an efficient method for analyzing cooking recipes. We present procedural texts using a flow graph, which can be referred to as a recipe tree, to represent cooking recipes and the database. A total of 110 kimchi jjigae recipes were identified and classified as 'portion', 'kinds of ingredients', and 'number of cooking deployment'. Recipes for two persons were the most common (43.6%), and 7-13 kinds of ingredients accounted for 50% of kimchi jjigae recipes. Kimchi presented the highest frequency at 78 cases, and pork showed the high frequency at 30 cases. To identify cooking deployment, step 6 was the highest, followed by step 5 (17.3%), step 7 (17.3%), step 4 (11.8%), and step 3 (9.1%). When analyzing the frequency of the relationship between ingredients and action in a recipe expression, Food (F) and Action by the chef (Ac) showed the highest rates at 11.29 and 12.30, respectively, in the cooking process. For frequencies of dependency relation expression in recipes, d-obj (direct object) was the highest at 13.56. The proposed method provides users more efficient and easier access to recipes suitable for their cooking skills.
This study was investigated the personal rating reason for preference, and opinion for improvement on the Korean traditional foods. Questionnaire were answered by male and female university students at 8 universities in Seoul and the results are summarized as follows. 1) General trend of subjects showed preference for traditional food in order of nutrition, appearance, taste, economics, and cooking method. While the value of food itself such as nutrition, appearance, taste was rated high, practical side such as economics, and cooking method was not so agreed. Especially female students set as lower value on cooking method. 2) As a reason for rating it low, male and female students answered without distinction that traditional food are laborious and much time is needed for cooking. 3) For the idea of improving traditional food, all students had same opinion that standardized cooking method should be developed for convenient use at home, and secondly, special salestore of traditional food should be promoted. Particularly more male students had the opinion that traditional cooking method should be succeeded to at home than female students. Summarizing some significant findings from the analysis of data, all students prefer traditional food itself relatiovely. But generally they rate it low because traditional food is difficult to cook and there are not so many chances of eating. Therefore, it is regarded that standardized cooking method and promoted special salestore for more chance of eating will activated the interest of young generation, and hence contribute to succession of tradition.
Purpose: High energy requirement and long cooking time are limiting consumption of pigeon pea (Cajanus cajan), a nutritious food. This study was performed to estimate energy and time demand by different methods of cooking pigeon pea. Methods: Pigeon pea (150 g) was soaked in 2.0 L of water at ambient temperature ($29{\pm} 2^{\circ}C$) to determine hydration behavior. Cooking experiments were conducted using aluminum and pressure-cooking pots. Efficiency of cooking was evaluated using four types of cooking appliances (kerosene, liquefied petroleum gas (LPG), electric, and charcoal stoves). Normal (continuous heating until the food was satisfactorily cooked) and control (controlling the energy input to closely match the actual energy required) cooking were conducted. Energy requirement and duration of cooking were determined using standard procedures. Results: Soaking increased moisture content from 11.99 to 30.01% in 90 min, while water absorption rate decreased with soaking duration. In cooking 150 g of pigeon pea using kerosene stove, presoaked normal pressure-pot cooking method consumed the least energy (10 800 kJ) and time (205 min), while unsoaked normal cooking consumed the highest energy (18 450 kJ) and time (336 min). Using LPG stove, unsoaked normal cooking method required the highest energy (52 470 kJ), while presoaked control pressure-pot required the least energy (14 405 kJ). For electric stove, the lowest energy (15 560 kJ) and shortest duration (105 min) were recorded during control cooking of presoaked sample in the pressure-pot. Conclusions: Control cooking was not practicable using charcoal stove. Generally, kerosene stove consumed the least energy, while electric stove was found to have the shortest duration of cooking.
This study was carried out to investigate preference and perception of seafood among soldiers on cook's duty in military meal service. 58.9% of the respondents answered that they liked seafood and the major eating place were in their home(48.0%) and in the restaurant(40.4%). The favorite seafood cooking methods turned out to eat as raw fish, to grill, to stew, to fry in order. In comparison with the meat dishes, seafoods were considered superior to meat in nutritional value but evaluated inferior to meat in the aspects of sanitation and tasteless problem. 32.9% of the respondents answered they liked seafood dishes in military meal service and they disliked them because of taste or cooking method of the seafood. They liked fried or grilled seafood in military meal service. The plate waste amounts of the seafood menu were more than half in almost every surveyed menu and reasons for plate waste were fish smell and taste problems. The difficulties of cooking seafood in military meal service were breaking down of seafood during cooking and complexity of cooking. They scored seafood higher than average in nutrition, taste, diversity of cooking method and aspect of health. On the basis of the results above, introducing diverse cooking methods and menu are suggested and education of cooking skills and development of cooking facilities are needed in military meal service.
This study was conducted to investigate the effect of taste and cooking method of medicinal cuisine on the customer loyalty. Self-administered questionnaires were collected from 214 customers visiting a restaurant specialized in temple cuisine in Yangsan city, Kyungnam province. Statistical data analysis was completed using SPSS program. Female respondents preferred garnish and bright color, and males preferred flavor and chewing taste as a taste of medicinal cuisine. The older respondents preferred flavor and chewing taste more than younger ones. Among cooking methods of medicinal cuisine, females preferred steaming and older respondents preferred boiling and cooking in casserole. From the regression analysis, the customer loyalty was singnificantly affected by sauce, delicious looking color, flavor, aroma, and chewy texture among taste factors and by boiling and cooking in casserole among cooking methods.

Objective: Sous-vide cooking offers several advantages for poultry meat, including enhanced tenderness, reduced cooking loss, and improved product yield. However, in duck meat, there are challenges associated with using the sous-vide method. The prolonged cooking time at low temperatures can lead to unstable microbial and oxidative stabilities. Thus, we aimed to assess how varying sous-vide cooking temperatures and durations affect the physicochemical and microbial characteristics of duck breast meat, with the goal of identifying an optimal cooking condition. Methods: Duck breast meat (Anas platyrhynchos) aged 42 days and with an average weight of 1,400±50 g, underwent cooking under various conditions (ranging from 50℃ to 80℃) for either 60 or 180 min. Then, physicochemical, microbial, and microstructural properties of the cooked duck breast meat were assessed. Results: Different cooking conditions affected the quality attributes of the meat. The cooking loss, lightness, yellowness, Hue angle, whiteness, and thiobarbituric acid reactive substance (TBARS) values of the duck breast meat increased with the increase in cooking temperature and time. In contrast, the redness and chroma values decreased with the increase in cooking temperature and time. Cooking of samples higher than 60℃ increased the volatile basic nitrogen contents and TBARS. Microbial analysis revealed the presence of Escherichia coli and Coliform only in the samples cooked at 50℃ and raw meat. Cooking at lower temperature and shorter time increased the tenderness of the meat. Microstructure analysis showed that the contraction of myofibrils and meat density increased upon increasing the cooking temperature and time. Conclusion: Our data indicate that the optimal sous-vide method for duck breast meat was cooking at 60℃ for 60 min. This temperature and time conditions showed good texture properties and microbial stability, and low level of TBARS of the duck breast meat.

The fat content of ground beef is the lowest in boiling cooking method. 2. The fatty-acids composition of ground beef is mainly palmitic and oleic acids. The fatty acids hardly change according to cooking methods. 3. P/S ratio is inclined to increase a bit after cooking than pre-cooking. From all the results obtained in this study it can be conclude that fat content is the lowest in boiling and microwaving cooking methods and fatty acid composition is mainly palmitic and oleic acids.
This study attempted to investigate the effect of housemaker's interest in dietary life on the knowledge of cooking principles and cooking methods, and on the daily meal management. Housemakers whose age ranged from 20 to 50 were surveyed in their residence. The results of this study were as follows. First, the level of interest in dietary life was positively related with ages, education and income levels. Moreover, housemaker who did not work or did not take care of relatives had higher level of interest in dietary life than those who did. Second, most housemakers bought foods and prepared a meal by themselves. The average time spent in preparing meals was 2 to 3 hours, and the number of side dishes cooked per day expect for the main dish was 5.46 percent of the total respondents ate out more than once a month for a 'family tie'. Third, there was no relation between the knowledge of cooking principle and the variables such as ages, education and income levels. Fourth, the level of the knowledge of cooking method about Korean traditional dishes was positively related with ages, education and income levels. In addition, housemakers who did not work or did not take care of relatives had less knowledge of Korean traditional dishes than those who did. Finally, the interest in dietary life was significantly correlated with the knowledge of cooking principle and cooking method of Korean traditional dishes.
