  • 건조 두류의 시료로 선정한 대두와 동부의 cooking time을 단축시킬 수 있는 방법을 개발하기 위하여 대두와 동부를 몇가지 선정된 soaking 및 cooking 방법으로 처리하여 cooking time을 비교하고, 이런 처리가 제품의 품질에 미치는 영향을 조사한 결과는 다음과 같다. 1. Soaking방법중 대두를 3%SBC 용액에, 동부를 $0.5{\sim}1%SBC$ 용액에 침지한 후 $95{\sim}100^{\circ}C$의 물에서 cooking했을 때 cooking time은 각각 40 분과 10분이였다 이는 control에 비하여 80%의 cooking time 단축에 해당한다. 2. 대두의 cooking방법중 $121^{\circ}C$에서 steam cooking 하는 것이 cooking time 단축에 가장 효과적 이었고 (15분), 동부의 cooking시간은 1%SBC 용액에서 6분, $121^{\circ}C$ steam에서 5분이었다. 3. 최적 텍스쳐에 도달한 각 시료의 품질을 평가한 결과 전체적인 선호도에서 $121^{\circ}C$에서 steam cooking 한 젓이 제일 좋았고, 염용액에서 침지한 시료는 control과 대등했으며, 염용액에서 cooking 한 것은 control 보다 좋지 않았다. 4. 위 결과를 종합해 볼 때 두류를 단 시간에 cooking할 수 있는 방법으로 대두는 가압 steam cooking $(121^{\circ}C)$ 또는 3%SBC 용액에서 침지하는 것이 효과적 이었으며, 동부의 경우 $0.5{\sim}1%SBC$ 용액에 침지 또는 가압 steam cooking$(121^{\circ}C)$ 하는 것이 효과적이다.

  • The purpose of this study was to investigate the influence of cooking wine's functions on food quality attributes. factor analysis, reliability analysis (Cronbach's $\alpha$), and multiple regression analysis were employed to analyze the data. The cooking wine functions were divided into 3 factors (expectation of utility, functionality, and quality enhancement). According to the multiple regression analysis of cooking wine factors to food quality, all factors had positive influences on food quality. Among the three factors, expectation of utility(=.556, p<0.001) had the most significant influence on food quality. And functionality (=.321, p<0.001) and quality enhancement(=.296, p<=0.001) also had significant effects in that order. further research should be conducted on cooking wine's utility aspects and their effects on food quality. Finally, we anticipate that the results of this study will be useful information for food-service companies.

  • Interaction between carcass quality grade and end-point cooking temperature on eating quality of Hanwoo m. longissimus was investigated. Ten (10) of steers were sampled from a commercial population; carcasses with QG 1++ (n=5) and QG 1 (n=5) were chosen. Samples were cooked by electric oven at 60 or 82℃ and compared with uncooked control samples. The pH was not affected by cooking temperature but decreased the redness after cooking and steaks cooked at 60℃ were more reddish than steaks cooked at 82℃ in both QG groups. Higher cooking temperature greatly (p<0.05) increased the cooking loss, but there was no significant interaction between cooking temperature and QG on the cooking loss. Moisture is negatively correlated with temperature in both QG while the proportionate relationship between crude fat and end-point temperature found in QG 1++. WBSF values were significantly (p<0.05) high for QG 1, while that was significantly (p<0.05) increased when the temperature continues to increase. The increasing quality grade of beef resulted in significant higher (p<0.01) level of TBARS and cooking temperature increased TBARS content. Fatty acid composition was not altered by cooking at both temperatures and also the amount of fat intake was not changed. The current study indicates that eating quality of beef m. longissimus was greatly influenced by end-point temperature being interacted with QG. However, the amount and composition of fat were stable regardless of end-point temperatures. These results will provide a consumer reference to determine cooking conditions and intramuscular fat content.

  • It attempted to determine the effect of various thawing methods, such as pressure cooking, conventional cooking, microwave heating and thawing at room temperature, on the quality of frozen cooked rice using Nongan variety of rice. These effects were analysed at three different periods-after 10 days, 30 days and 90 days. It conducted a physico-chemical analysis(moisture content, dehydration rates, color value and texture) and sensory evaluation o the frozen-thawed cooked rice. The study showed that there were no significant differences on the frozen-thawed cooked rice. The study showed that there were no significant differences on the quality characteristics of frozen-thawed cooked rice during the storage of 90 days. However, the thawing method of pressure cooking caused high moisture content and decrease in hardness on the cooked rice, the desirability for the rice didn't diminish compared with the cooked rice just after cooking. the quality characteristics of the cooked rice after frozen-thawing by conventional cooking and microwave heating were similar with that of the cooked rice just after cooking. thawing at room temperature caused a significant decrease in quality characteristics.

  • We evaluated the effects of pre-cooking methods on the quality of reheated marinated pork loin. Frozen marinated pork loins cooked using various methods (boiling, grilling, pan frying, infrared cooking, and superheated steam cooking) were reheated in a microwave, and their pH, color, cooking loss, re-heating loss, total loss, thiobarbituric acid reactive substance (TBARS) value, sensory properties, and shear force were determined. Although all parameters varied with different cooking methods, lightness values and TBARS values showed the tendency to decrease and increase, respectively, after reheating. Superheated steam-cooked samples showed the lowest values of cooking loss, total loss, TBARS value, and shear force (p<0.05) and the highest lightness, redness, and yellowssness values and juiciness, chewiness, and overall acceptability scores (p<0.05). These results show that pre-cooking with superheated steam maintains the quality characteristics of marinated pork loin upon reheating. Therefore, pre-cooking with superheated steam may be beneficial for the commercial distribution of frozen cooked marinated pork loin.

  • 국수 조리시 조직감 향상을 위해 소금, 기름과 설탕을 각각 1%의 농도로 삶는 물에 첨가한 후 조리 특성과 조직감을 측정한 결과, 1%의 소금을 첨가하여 국수를 삶은 경우 83 g의 무게를 보였으며, 삶은 후의 부피 또한 72 $m\ell$로 낮은 함수율을 보였으며, 조직감 역시 우수하였다. 염의 종류를 각각 달리하여 첨가한 경우 NaCl, CaCl,, MgSO$_4$간의 조리 특성은 큰 차이가 없었으며, 염의 종류에 따른 조직감의 유의적 차이는 없었으나, NaCl를 첨가한 경우 다른 염을 첨가한 경우에 비해 다소 우수한 조직감을 보였다. NaCl 첨가농도를 달리하여 조리특성과 조직감을 비교한 결과, 조리 후 무게와 부피의 증가가 NaCl 첨가 농도가 증가할수록 감소하는 경향을 보였다. 염의 농도가 증가할수록 이들의 조직감이 증가하는 경향을 보였으나 이들 염의 농도에 따른 유의적 차이는 관찰되지 않았다. 그러나 염을 첨가하지 않은 경우에 비해 5%의 염을 첨가한 경우에는 이들 조직감에 유의적 차이를 보였다.

  • Background: PM2.5 and black carbon (BC) can be generated from cooking and from vehicle operation. Street vendors may be exposed to PM2.5 and BC due to their proximity both to roads and to cooking activities. Objectives: The objectives of this study were to evaluate the PM2.5 and BC concentrations in cooking stalls and to determine the effects of cooking activity and of types of cooking. Methods: Indoor and outdoor PM2.5 and BC concentrations, temperature, and relative humidity were measured in 32 stalls in April and May 2022. Behavioral factors such as the presence of cooking activity and types of cooking were observed. Student's T-test was performed using the difference of indoor and outdoor PM2.5 and BC concentrations to compare the effects of cooking activity and to compare types of cooking. Results: One-hour averages of the difference in indoor and outdoor PM2.5 concentrations for cooking stalls and non-cooking stalls were 9.7±15.7 ㎍/m3 (n=22) and -0.5±0.4 ㎍/m3 (n=10), respectively. The difference in indoor and outdoor PM2.5 concentrations in cooking stalls was significantly higher than in non-cooking stalls (p<0.05). The indoor PM2.5 concentration for stalls for Chinese pancakes and teokbokki exceeded the standards for indoor air quality in South Korea (50 ㎍/m3 ). The indoor PM2.5 concentration for Korean pancake stalls exceeded the standards for outdoor air quality in South Korea (35 ㎍/m3 for 24 hours). Conclusions: The PM2.5 concentrations in stalls with cooking activity was significantly higher than those in stalls without cooking activity. Some stalls with certain types of foods exceeded standards for indoor and outdoor air quality in South Korea. Better management of indoor air quality in stalls with cooking activities is necessary.

  • This study attempted to determine the effect of various thawing methods and storage periods on the quality of froen cooked rice. Frozen cooked rice was thawed at four different methods, such as pressure cooking, conventional cooking, microwave heating and thawing at room temperature after 10 days, 30days and 90 days frozen storage. We conducted a physico-chemical analysis (moisture content, dehydration rates, degree of gelatinization, color value and texture) and sensory evalution on the frozen-thawed cooked rice. The study showed that there were no significant differences on the quality characteristics of frozen-thawed cooked rice during the storage period of 90 days. However, the thawing method of pressure cooking caused high moisture content, rapid dehydration rates, and a high degree of gelatinization on the cooked rice. Thus, the desirabililty for the rice diminished becaused of the excess moisture content and the change of appearance and testure in the rice due to the high temperature. There were similiar quality characteristics to the cooked rice after forzen-thawing whether by conventional cooking or by microwave heating and just after cooking. Thawing at room temperature also caused a significant decrease in quality characteristics.

  • Buffalo meat patties with two fat levels, F1 (15% added fat) and F2 (5% added fat and 3% tapioca starch), were cooked in a pre-heated hot air oven (HO) at $175{\pm}2^{\circ}C$ for 15 min, in a microwave oven (MO) for 70 sec and by pressure cooking (PC) at 15 psi pressure for 10 min. and compared for physico-chemical, processing, sensory and microbiological quality attributes. F2 had significantly (p<0.05) higher value for the moisture and moisture protein ratio than F1. However, MO and PC patties had significantly (p<0.05) higher moisture content than HO-cooked buffalo meat patties irrespective of fat content. Highest fat percentage was in MO patties while the minimum was in PC patties. Moisture and fat retention and cooking yield were highest in MO patties irrespective of added fat content in the formulation. Cooking yield and dimensional parameters were better maintained in F2 than F1. Sensory scores viz. appearance and color, flavour, juiciness and texture for HO patties were better than other cooking methods. Sensory panelists rated overall acceptability of HO patties very good to excellent, whereas PC and MO patties were rated as good to very good irrespective of fat content. Microbiological quality was comparable in both groups irrespective of cooking methods used.

  • Quality changes of cooked meat products are dependent upon cooking temperature and heating methods. Pork ham is the most preferred pork dish using pork hams in South Korea although it is not suited to various cooking methods because its low fat content does not provide desirable physiochemical and sensory properties to consumers. Therefore, the objective of this study was to evaluate the effect of four different cooking methods on pork legs by comparing Ocoo, Sous-vide, steaming, and boiling technique at $80^{\circ}C$ and $100^{\circ}C$. Ultimately, the most effective cooking method and temperature to improve the quality of cooked pork hams was investigated. As the results of texture analysis, the samples cooked using Ocoo and Sous-vide methods showed higher springiness and cohesiveness than those using steaming and boiling methods. For the sensory evaluation, participants liked the hardness, juiciness, chewiness, tenderness of the samples using the OC method, resulting in the highest overall acceptance rate. The results of this study showed that using Ocoo or Sous-Vide cooking methods can improve the quality of cooked pork hams in both physicochemical and sensory properties.
