The aim of this study is to highlight the importance of the correct food choices and nutrition management through nutrition labeling and provide basic data for building a nutrition labeling system for Korean restaurants. In the study, a survey was conducted from February 5th to February 27th in 2010 involving adults over the age of 20 living in part of the Gyeonggi-do area. The data was used to analyze the general characteristics, the awareness of nutrition labeling and the nutrition labeling contents by using the SPSS 18.0 package program. Among the 268 people surveyed, the total number of women was greater (60.4%) than men (39.6%). The perception of the necessity of nutrition labeling was a relatively high score of 3.99 on a 1 to 5 scale and the motivation to utilize nutrition labeling scored 3.89. The study found that females perceived nutrition labeling to be more important than did the males. In addition, the perception varied according to the level of education and age. In conclusion, since customers have a high demand for nutrition labeling in Korean restaurants and are motivated to utilize labeling when eating-out is relatively strong, labeling would be a good educational tool for leading a healthy food life. Furthermore, since the study found that differences occur between nutrition labeling contents or nutrients according to general characteristics, food service companies might be able to gain benefits through differentiated nutrition labeling that is catered for their main customers.

본 연구는 무, 마늘, 생강 등 모든 부재료가 모두 즙액으로 된 양념액과 식초와 겨자 추출액을 사용하여 김치가 양념액에 잠기도록 제조하여 미생물의 증식 억제 및 가식기간 연장 그리고 김치의 맛을 향상시키고자 시도되었으며, 더불어 김치에 색과 맛과 기능성을 강화하기 위하여 들깻잎, 엔다이브잎, 청겨자잎을 절인배추에 첨가하고, $25^{\circ}C$에 9일간 저장하면서 김치의 품질을 연구하였다. 식초와 겨자를 첨가하지 않은 대조군의 김치 국물의 pH는 제조 후 1일에 $5.40{\pm}0.01$이었으나 식초와 겨자 추출액이 첨가된 실험군은 pH가 $4.51{\pm}0.01{\sim}4.52{\pm}0.01$으로 대조군보다 유의적으로 낮았으며, 숙성이 진행되면서 대조군의 pH는 급격히 감소하였으나, 식초와 겨자 추출액을 첨가한 실험군들의 pH가 서서히 감소하였다. 김치 조직도 김치 국물과 유사한 양상을 보였다. 대조군이 실험군들에 비해 초기 산도가 낮았으나, 발효가 진행됨에 따라 증가 현상이 뚜렷하여 김치 제조 후 1일에 $0.28{\pm}0.03$이었으나, 3일이 지나자 $0.95{\pm}0.04$이 되었다. 반면, 실험군들에서는 제조 후 1일에 $0.42{\pm}0.01{\sim}0.43{\pm}0.02$으로 대조군보다 높았고, 3일까지는 변화가 거의 없다가 5일 후부터는 대조군과 유사해지기 시작했다. 김치 조직의 산도는 전반적으로 김치 국물보다 낮게 나타났고, 산도의 변화 양상은 김치 국물과 유사하였다. 김치 국물의 염도는 대조군과 실험군들 모두 제조 1일 후에 가장 높아 $2.67{\pm}0.06{\sim}2.80{\pm}0.10%$이었으나, 발효가 진행됨에 따라 점차 감소하였다. 김치 조직의 염도도 숙성이 진행됨에 따라 점차 감소하였으며, 전반적으로 김치 국물보다 낮았다. 젖산균수는 대조군의 경우 김치 제조 후 1일 후에 $8.17{\pm}4.01{\times}10^8cfu/g$으로 실험군들의 $2.70{\pm}2.08{\times}10^7{\sim}3.63{\pm}2.80{\times}10^7cfu/g$보다 많았으며, 3일 후에는 더욱 차이가 나서 대조군은 $3.13{\pm}1.94{\times}10^{11}cfu/g$, 실험군들은 $2.47{\pm}2.23{\times}10^9{\sim}8.03{\pm}3.71{\times}10^9cfu/g$이었다. 그러나 김치 제조 7일이 지나자 대조군과 실험군들 간에 젖산균수 사이에는 유의적인 차이가 없는 것으로 나타났다. 김치 제조 후 1일의 김치의 색의 경우 대조군의 경우 $2.4{\pm}0.5$이었으나, 식초와 겨자 추출물을 첨가한 실험군들은 $2.9{\pm}0.7{\sim}3.9{\pm}0.7$로 대조군보다 유의적으로 좋다고 하였으며, 냄새도 실험군들이 대조군보다 좋은 평가를 받았다. 이러한 결과는 맛과 조직감 및 전반적인 기호도에서도 같은 결과를 나타내, 대조군보다 실험군들이 모든 항목에서 더 좋다는 유의적인 결과를 보여주었다(p<0.05). 대조군의 pH가 $4.09{\pm}0.01$로 적숙기가 지난 것으로 나타난 김치 제조 후 3일 째인 경우 실험군들은 모두 pH가 $4.55{\pm}0.01{\sim}4.57{\pm}0.01$로 여전히 김치 적숙기의 pH에는 도달하지 않았으나, 관능검사의 모든 항목에서 대조군보다 유의적으로 좋은 것으로 나타났다. 전반적 기호도에서는 들깻잎을 첨가한 실험군 B가 $5.0{\pm}0.0$으로 '가장 좋다'는 점수를 받았으며, 그리고 순서대로 식초와 겨자 추출액 만을 넣은 실험군 A, 엔다이브잎과 청겨자잎을 넣은 실험군 C과 D이었으며, 대조군이 $1.1{\pm}0.4$로 가장 나쁘다고 하였다. 김치 제조 5일 째의 경우에도 모든 항목에서 실험군들이 대조군보다 유의적으로 좋게 The aim of this study was to investigate the quality characteristics of Kimchi, prepared with seasoning fluid, vinegar, and mustard extract to inhibit the proliferation of microorganisms and extend the edible period during fermentation at $25^{\circ}C$. We also added perilla leaf, endive, and mustard leaf to Kimchi to improve the flavor. The pH of control Kimchi fluid over 1 day after Kimchi processing, was $5.40{\pm}0.01$ and that of the experimental groups in which vinegar and mustard extract were added was $4.51{\pm}0.01{\sim}4.52{\pm}0.01$, which was lower than that of the control. As the fermentation progresses, the pH of the control decreased rapidly and that of the experimental groups decreased slowly. The initial titratible acidity of the control was low and 3 days later reached $0.95{\pm}0.04$. However, that of the experimental groups was $0.42{\pm}0.01{\sim}0.43{\pm}0.02$ and 5 days later reached a level similar to that of the control. The salinities of the Kimchi juice of both the control and the experimental groups were $2.67{\pm}0.06{\sim}2.80{\pm}0.10$% after 1 day and decreased during fermentation. The amount of lactic acid bacteria of the control was $8.17{\pm}4.01{\times}10^8cfu/g$, 1 day after the Kimchi processing and that of the experimental groups was $2.70{\pm}2.08{\times}10^7{\sim}3.63{\pm}2.80{\times}10^7cfu/g$. After 3 days, these were $3.13{\pm}1.94{\times}10^{11}cfu/g$ and $2.47{\pm}2.23{\times}10^9{\sim}8.03{\pm}3.71{\times}10^9cfu/g$, respectively. According to the result of sensory evaluation, throughout the entire period of the experiment, all sensory items such as color, odor, taste, texture, and total acceptability of the experimental groups were better than those of the control group (p<0.05). Especially, Kimchi in which perilla leaf was added was the best. With the addition of vinegar and mustard extract to the Kimchi, microorganism proliferation was inhibited and the edible period was extended. The minerals, vitamins and antioxidants of leaf vegetables could therefore be obtained.

The aim of this study was to investigate the quality characteristics of sponge cakes with added rice flour produced by a modified genoise method to prevent volume reduction. A control group and experimental group Ⅰ were prepared by the genoise method and experimental groups Ⅱ, Ⅲ, and Ⅳ were produced by a modified genoise method in which they were mixed with wheat flour and water to a make paste to form gluten for 3, 6, and 9 minutes, respectively. One third of the wheat flour in all experimental groups was replaced by rice flour. The control and experimental groups were compared in terms of quality characteristics, including batter specific gravity, volume, color, textural characteristics, and sensory qualities, to determine the optimal pasting time for wheat flour in the formulation. The specific gravity of the experimental groups was higher than that of the control and decreased with increasing wheat flour pasting time. The volume of experimental group Ⅰ was lower than that of the control group, and the volume values of experimental groups Ⅲ and Ⅳ, made by the modified genoise method, were higher than that of the control group. dL* and db* values for the crust and inside of the cake were lower in the experimental groups than in the control. The dL* value, indicating brightness, increased as pasting time increased. The hardness values of experimental groups Ⅰ and Ⅳ were higher than that of the control whereas experimental groups Ⅱ and Ⅲ had lower hardness values. Chewiness was higher in the control group, as well as experimental groups Ⅰ and Ⅳ than in the experimental groups Ⅱ and Ⅲ. The gumminess of experimental group Ⅳ was highest. Cohesiveness decreased by adding rice flour to the sponge cake. Sensory attributes of cell uniformity, tenderness, moistness, taste, and overall acceptability had the highest scores in experimental group Ⅲ. Based on these results, we conclude that the quality of sponge cake containing one third of the wheat flour replaced by rice flour is best with 6 minutes pasting of the wheat flour to form gluten.

In this study, we investigated the effects of sweeteners on the quality of Kakdugi through the addition of 1.8% sugar, 0.006% sodium saccharin or 0.006% stevioside using a physicochemical test and sensory evaluation during fermentation at 20℃. The addition of sugar to Kakdugi resulted in the lowest pH and the highest total acidity relative to the control and experimental groups during the fermentation period. The number of lactic acid microorganism gradually increased and then decreased. The sensory evaluation revealed that the addition of sodium saccharin to Kakdugi resulted in the highest sweet smell and taste followed by the addition of stevioside. The addition of sodium saccharin to Kakdugi showed the highest sweet taste and the best texture, and the sweetness compensated for the sour smell and taste.

The principal objective of this study was to investigate the association of variable salts with the hardness of cubed white radish. We analyzed the contents of domestic sun-dried salt, Chinese sun-dried salt, domestic refined salt, Australian rock salt and Australian industrial sun-dried salt in the radish samples. Our assessment of the water content of variable salts showed that domestic refined salt was highest(7.27%) and Australian rock salt was lowest(0.16%). The NaCl contents of variable salts were as follows: 93.23% in refined salt, 93.76% in Australian rock salt, 87.85% in domestic Shinan sun-dried salt and 87.98% in Chinese sun-dried salt. The content of insoluble matter in water were 0.03~0.05% in all salts except 0.85% in Australian industrial sun-dried salt. The pH values of salts were as follows: 8.93 in domestic sun-dried salt, 8.62 in Chinese sun-dried salt, 6.69 in refined salt, 5.83 in Australian rock salt and 6.41 in Australian industrial sun-dried salt. Regarding the mineral component content assays, domestic salt was found to harbor lower Na content but far higher Mg, K, Ca contents than other salts. In our evaluation of the hardness of cubed white radish, we detected a continuous increase in the hardness of cubed white radish soaking in a 4% salt solution of domestic Shinan natural salt, but an initial increase followed by a decrease in the hardness of cubed white radish soaking in a 4% solution of the other salts.

The purpose of this research was to study food behaviors and nutrient intakes according to body mass index(BMI) and body image recognition in 211 female university students in Incheon. The majority of the surveyed subjects were in the normal range for BMI. Most of these female university students preferred a thin body type and were not satisfied with their body shapes. Most also controlled their body weight for appearance by exercising and limiting food intake. The obese group often ate processed foods(p<0.01) and ate out(p<0.05). The underweight group and normal-weight group took vitamins and supplements more frequently(p<0.001). Those students who recognized their body image as a ``fat shape`` had good appetites(p<0.05) and those who recognized themselves as ``normal shape`` considered food formulations ate every meal (p<0.05) and consumed vitamins and other supplements frequently(p<0.01). The mean calorie intake of all students was about 80% of the recommend amount, so there was a risk of lack of various nutrients. The ``fat`` students by body image recognition had lower calorie intakes in order to reduce body weight. In all the groups, there was a lack of vitamins B1 and B2, as well as the minerals Ca and Fe. Therefore, education on correct body image recognition and training on proper weight control are deemed necessary. In addition, education and counseling on nutrition that are tailored to individual status are needed.

A study was undertaken to examine the effect of the addition of job`s tears(Coixlachryma-jobi L.) chungkukjang(soybeanfermented food) and wheat bran powder on quality attributes of pound cakes. Job`s tears chungkukjang and wheat bran powder was added to the batter at a ratio of 10, 12.5 and 15% respectively. The antioxidant activity was estimated by DPPH free radical scavening activity, the total phenolic compounds content and flavonoid content in job`s tears chungkukjang & wheat bran powder and pounds cakes. Antioxidative activity was highly correlated with the total phenolic and total flavonoids contents of job`s tears chungkukjang and wheat bran pound cakes respectively(r=0.9671, r=0.8335). The quality characteristics of job`s tears chungkukjang powder and wheat bran powder pound cakes were estimated in terms of the specific load volume, hardness, hunter value of crumb and crust and sensory quality of cakes. The specific volume were increased significantly with increasing substitution level of job`s tears chungkukjang and wheat bran powder(p<0.01). The lightness were significantly decreased with increases in job`s tears chungkukjang and wheat bran powder of pound cake crust and crumb(p<0.01, p<0.01). The hardness, chewiness and gumminess were tended to reduce, while cohesiveness with increase in both of powder. The consumer acceptability score for 10~15% job`s tears chungkukjang and wheat bran powder pound cakes ranked significantly(p<0.01) higher than those of the other groups in taste, flavor and overall preference. This results showed that job`s tears chungkukjang and wheat bran powder are a good ingredient to increase consumer acceptability and the healthy.
