This study aims to find out how taste recognition differs between two groups of culinary arts students. We conducted a questionnaire survey on minimum sensitivity and minimum tastiness for four basic tastes. The first group consisted of 40 students in their first year, and the second group consists of 56 students in their second year and third year. The survey shows that both groups preferred medium saltiness, and the second group was more favorable to sweetness than the first group. The sweet and the pungent tastes were more favored than sourness and less favored than bitterness by both groups of subjects. The amount of the sample required for minimum tastiness shows that the freshmen had a higher sensitivity than the sophomore and junior students. Contrary to a common belief that people who have more experience in cooking would have a more sensitive taste, this study shows that taste sensitivity does not always accord with cooking experience. Rather, it depends on individual differences and current health status. Further research should be needed for various sensory test method and more kitchen experienced people who has more working years after graduate college.

The purpose of this study was to analyze the sensory and mechanical characteristics, moisture content and color values of Hongwhasulgi by varying the quantity of Safflower seed powder and the types of sugar used. As a result of the quantitative analysis, it was found that as more Safflower seed powder was added to the non-glutinous rice powder, the tastiness, sweetness and coarseness of the resultant rice cake tasted almost the same as that of the raw seeds. When the quantity of the seed powder was the same, Hongwhasulgi with sugar added was moister than that with oligosaccharide, and as more seed powder was added, the rice cake became less chewy. The preference of flavor did not differ significantly among the samples. As a result of analyzing the texture, Hongwhasulgi with more Safflower seed power added and oligosaccharide used exhibited greater hardness, adhesiveness, gumminess and chewiness but lower cohesiveness, whereas springiness did not differ significantly among the samples. The moisture content of Hongwhasulgi ranged from $32.35{\sim}39.87%$. Hongwhasulgi with the sugar added was significantly moister than that with oligosaccharide added(p<0.05). Based on the above results, it is considered that the most desirable mix ratio for Hongwhasulgi is non-glutinous rice powder 190 g(95%), Safflower seed power 10 g(5%), sugar 20 g, salt 2 g, and water 35 mL.

This study was carried out on hospitalized patients receiving diet therapy satisfaction and awareness of nutrition education in small and medium-sized hospitals in southern Gyeonggi area. By the face-to-face interview with questionnaire method, the survey was carried out on 150 subjects (99 males and 51 females). The patients (64.7% of males, 52.9% of females) heard the description of diet therapy without the aid of written manual. Patients were moderately satisfied by food that was rated based on these indicators: tastiness (2.45), saltiness (2.23), smelliness (2.23), and appetizing appearance (2.39) as a 4 point scale. Most of the patients (80.8% of males, 69.8% of females) wanted to continue diet therapy. The importance of diet was correlated with the tastiness, saltiness, and appetizing appearance of diet. And the help of dietitians' explanation was correlated with appetite. 55.6% of males and 35.4% of females received nutrition education before (p<0.05). The number of times nutrition education was received was once for male (33.3%) and three times for female (44.4%). Most nutrition education satisfaction that was calculated on a 4 point scale was well understood (3.03), recognized importance (3.44 for males, 2.78 for females) and help for disease management (p<0.01). Also they were satisfied with the explanation of disease (3.20). Nutrition education satisfaction was correlated positively with explanation about food related to disease, the current dietary treatment, how to prepare diet recipes, and dietitian's kindness, but negatively with satisfaction with explanation of diet therapy, and the description and help for disease management. In conclusion, the most important factor in practicing diet therapy was meeting with the dietitian. Intensive nutrition education after the patient's discharge is necessary for patients to continue diet therapy.

두부 제조 시 응고제로 $CaCl_2$을 사용하고, 두부에 간을 배게 하여 두부의 맛에 대한 품질향상을 목적으로 정제염, 천일염, 죽염, 심층해염을 첨가한 실험군 쑥두부와 염을 첨가하지 않은 대조군 쑥두부의 수율, 일반성분, 조직감 측정 및 관능검사를 실시하였다. 천일염, 죽염, 심층해염을 첨가한 쑥두부의 수율은 $202.29%{\sim}207.50%$로 염을 첨가하지 않은 대조군의 수율 185.1%에 비하여 통계적으로 유의하게(p<0.001) 높았다. 그리고 조지방, 조단백질, 조회분의 함량은 다양한 염을 첨가한 실험군 쑥두부가 염을 첨가하지 않은 대조군에 비하여 통계적으로 유의하게(p<0.001) 높게 나타났다. 조직감 측정에서는 hardness와 gumminess에서 실험군 쑥두부가 대조군 쑥두부보다 유의적으로(p<0.05) 높은 값을 보였지만 brittleness와 cohesiveness, chewiness에선 유의적인 차이점을 찾지 못하였다. 관능검사 결과는 경도와 탄력성에선 유의적인 차이점이 없었지만 짠맛, 구수한 맛, 씹힘성, 전체적 기호도에선 대조군 쑥두부보다 염을 첨가한 실험군 쑥두부가 통계적으로 유의하게(p<0.001) 높은 점수를 받았으며, 특히 죽염 쑥두부와 심층해염 쑥두부에서 두부 맛에 영향을 미치는 구수한 맛과 전체적 기호도에서 높은 점수를 받았다.

유기오리의 도체중은 일반오리보다 품종 및 사양방법의 차이에 기인하여 낮게 나타났으나 도체율에서는 큰 차이가 없었다. 가슴부위의 정육율에서는 일반오리(11.95%)보다 높게 나타났으며, 다리부위(13.07%)에서는 일반오리(14.2%)보다 다소 낮게 나타났으나 유의적인 차이는 보이지 않았다(p<0.05). 도축 직후 측정된 유기오리의 pH는 가슴 및 다리부위에서 각각 6.48 및 6.73으로 일반오리보다 높게 나타났는데 일반적으로 다리부위의 pH값이 가슴육보다 유의적으로 나타났다(p<0.05). 유기오리육에서 다리근육이 가슴근육 보다 낮은 가열감량을 나타내었다. 따라서 유기오리에 대한 일반 이화학적 검사 결과 일반오리육보다 높은 pH, 높은 전단력, 낮은 가열감량 등이 우수하였다. 관능검사 결과 육질 및 냄새, 연도, 맛에 있어서 일반오리보다 좋은 기호도를 보였으며 이와 같은 결과 전체적으로 우수한 식육 자원으로서 육제품 개발에도 충분한 가치가 있는 것으로 사료된다.
