This study investigated the quality characteristics of $Jajang$ noodles with added spinach (20%, 30% and 50% based on water). Significant increases ($p$<0.05) were found in cooked weight, water absorption of cooked noodles, turbidity of soup, while soup volume did not changed in proportion to the addition of spinach. Decrease of L and a values and an increase of b values were shown with the increase of spinach concentration. For textural properties, hardness was the lowest in 50% spinach noodles and the highest in 20% spinach noodles. The cohesiveness and springiness values of 20% and 30% spinach noodles were superior to those of the control, but a rise in spinach concentration (50%) lead to a reduction these values. In a sensory evaluation, the most acceptable sample was the 30% spinach noodle sample. These results suggest an addition of 30% spinach is suitable for spinach $Jajang$ noodle processing.

Cook/chill 및 sous-vide 시금치국을 국내 단체급식소에 적용시키기 위해 cook-chill 및 sous-vide 처리한 시금치국을 1일, 3일, 5일간 3$^{\circ}C$에서 냉장저장 시켰다. 이 제품을 중탕, 직화, steam/convection oven, 전자렌지를 이용하여 재가열한 후 관능평가를 수행하였고 이에 대한 결과는 다음과 같다. 재가열 방법에 따른 결과에서 1일 냉장 저장 후 재가열한 시금치국은 맛과 외관은 steam/convection oven에서, 냄새와 질감은 전자렌지에서 관능평가 점수가 높게 나타났고, 3일 냉장 저장 후 재가열한 시금치국은 맛과 외관은 중탕에서, 냄새와 색상, 전체적인 수응도는 직화에서 관능평가 점수가 높게 나타났으나 모두 유의적인 차이를 보이지 않았다. 5일 냉장 저장 후 재가열한 시금치국은 맛, 냄새와 전체적인 수응도는 전자렌지에서, 색상, 질감과 외관은 직화에서 관능평가 점수가 높았으나 유의적인 차이는 없었다. 재가열 방법에 따른 차이에서는 중탕방법이 전반적으로 관능평가 점수가 가장 우수하게 나타났다. 전통조리법을 이용한 시금치국(대조군)과 재가열 한 시금치국(처리군)을 비교한 결과, 색상에서 처리군이 대조군보다 유의적(p＜0.01)으로 낮은 관능평가 점수를 보였다. 맛에서는 3일 저장한 처리군과 5일 저장한 처리군은 대조군보다 모두 유의적(p＜0.05)으로 높은 관능평가 점수를 보였다. 저장기간에 따른 관능평가 점수 결과에서, 중탕을 이용한 경우 색상, 질감이 저장기간이 증가함에 따라 관능평가 점수가 감소하였으나 유의적인 차이는 보이지 않았다. 직화를 이용한 경우 냄새와 질감은 저장기간이 증가함에 따라 유의적으로(p<0.05) 높은 관능평가 점수를 보였다. 전자렌지를 이용한 경우, 맛, 냄새, 전체적인 수응도는 저장기간이 증감함에 따라 관능평가 점수가 증가하였고, Steam/convection oven을 이용한 경우, 저장기간이 증가함에 따라 맛, 냄새, 외관의 관능평가 점수는 높아졌으나 모두 유의적인 차이는 보이지 않았다. 저장기간에 따른 차이에서는 1일 저장한 시금치국이 전반적으로 관능평가 점수가 가장 우수하게 나타났다. 이상을 살펴볼 때, cook/chill 과 sous-vide를 활용한 시금치국은 녹색채소의 특성을 고려한 색상에 대한 개선 연구가 필요하고, steam/convection oven 이외에 다양한 재가열 방법의 활용이 가능하므로 국내 단체급식소에서도 주방시설에 많은 투자를 하지 않고 기존의 시설로도 이러한 제품을 이용할 수 있다. 따라서 cook/chill과 sous-vide의 가공방법을 활용한 다양한 제품들의 개발을 통해 식자재의 새로운 공급방법이 체계적으로 이루어지고 발전한다면 앞으로 국내 단체급식업체는 생산과정에 새로운 전환점이 될 수 있을 것이다.

This research was conducted to examine the awareness and preference levels related to MSG (monosodium glutamate) according to well-being dietary life pursuit attitude factors as well as to improve opportunities to meet value conscious consumption of well-being-oriented customers. According to well-being dietary life pursuit attitude factors, respondents were divided to three clusters, indifference type, well-being-oriented type, and active health action type. Sensory evaluations were carried out on soybean paste soup (Doenjang-guk) and seasoned spinach with different levels of MSG. In the results, 74.4% of all respondents preferred Doenjang soup with 2% MSG, 65.4% preferred seasoned spinach with the same ratio of MSG, and 35.9% preferred seasoned spinach with 0.5% MSG. Regarding the acceptance level of MSG, addition of MSG to improve taste was acceptable to the indifference type (cluster 1). On the contrary, active health action type did not prefer MSG, wanted natural seasonings despite high prices, and preferred to dine at restaurants that serve MSG-free foods. Based on this study, restaurant companies should segment their customers on the basis of MSG usage and establish their positioning strategies according to their concepts.

Sodium is a necessary element for the body. Excessive intake of sodium is known as one of the risk factors for chronic diseases. Recently, increasing numbers of people in Korea are suffering from chronic diseases. Major causes of deaths were chronic degenerative disease with the rising aging population. Especially, the population of rural areas is growing older fast. In rural areas, it is known that under nutrition and high sodium intake were major nutritional problems. For sodium intake, there were some studies about contributing food items. They were not enough to show diets relate to sodium intakes. Thus, this study analyzed dishes contributing to sodium intakes of elderly living in rural areas. Dietary intakes using "the 24hour recall method" were used. For the analysis for sodium intakes, "Can-pro3.0" was used. Ranking of dishes by contributions of sodium intakes were Korean cabbage, kimchi (19.6%), seasoned soybean paste (5.3%), soybean paste (4.6%), soybean paste soup dried radish leaves (3.5%), hot pork and kimchi stew (3.4%) in order. Ranking of dish groups by sodium intakes was kimchies (28.3%), soup and hot soups (22.8%), stews and casseroles (9.7%), seasonings (8.2%),and seasoned vegetables (6.0%) in order. One-dish meals among cooked rice, wheat noodles among noodle and mandu, soups using the soybean paste, stews using soybean paste and kimchi, salted fish among grilled foods, stir-fried anchovy among stir-fried foods, seasoned spinach, and Korean cabbage kimchi contributed to sodium intakes. As the nutrition deficiency of the elderly living in rural areas could be a problem, and excessive sodium intakes is threatening to their health, it is needed for the senior citizens to have adequate knowledge for diets containing less sodium. And recipes for healthy food and nutrition education based on their diets are needed.
