This study was carried out to investigate food-nutrition labeling perception and utilization classified by age in Busan. The survey was conducted from March 26 to April 30, 2008 by questionnaires and data analyzed by SPSS program. The results are summarized as follows: reasons for purchase of the processed food was 'delicious' in elementary school children and middle & high school students, but was 'easy to eat and cook' in the adults groups (p<0.001). The criteria for choice of the processed foods was 'taste' in all of the subjects. Eighty seven point five percent of the over 60's do not know about food labeling and 70.1% of them did not check the food label. The first confirmed items for buying the processed foods was 'expiration date' in all of the subjects (71.1%). In elementary school children, middle & high school students, 20's & 30's group, the ratio of awareness of nutrition label was higher than the 40's & 50's and over 60's group. For reading of nutrition label, all of the subjects except elementary group replied 'often' (p<0.001). For the experience of education and publicity on food-nutrition labeling, 54.3% of the subjects replied 'often', and there was a significant difference by age. For the necessity of education and publicity on food-nutrition labeling, 49.5% of the subjects replied 'necessary'. There was significant positive correlation between degree of checking of nutrition label and degree of checking of food label, accuracy of knowledge of processed food, necessity of education and publicity. Therefore, education and publicity on food-nutrition labeling for the subjects are required to encourage them to choose more nutritious food and have healthier dietary pattern.

This study investigated relationships between the importance and satisfaction of rice-based menu selection attributes at family restaurants. For data collection, a total of 250 copies of questionnaires were distributed to 4-year college students who had an experience of a rice-based menu at casual dining restaurants, and finally 221 surveys (88.4%) among them were analyzed by using SPSS Win ver. 11.5. Twenty selection attributes were used to test the level of importance and satisfaction for rice-based menu. The factor analysis identified six dimensions of the importance of rice-based menu selection attributes; variety of items, menu information, recommendation & atmosphere, food quality, preferred menu, and price. Also, five dimensions of satisfaction were identified as nutrition & taste, menu information, preferred menu & atmosphere, variety of items, and cooking. Canonical correlation analysis revealed that preferred menu factor of importance was highly correlated with preferred menu and restaurant atmosphere factor of satisfaction of rice-based menu selection. The managerial implications of these results for rice-base menu selection attributes are as follows: There seems to be a need to develop a variety of rice-based menus, because rice-based menus tend to be considered as an additional menu, not a main course. Aggressive marketing and communication strategies are necessary to position rice-based menu as a main course for college students and as a major maket segment to family restaurants.

The purpose of this study was to find out the optimal mixing ratio of green tea powder, sugar, and water for the preparation of Seolgiddeok through Response Surface Methodology based on the color, sensory, and texture test. The oganoleptic and textural properties of Seolgiddeok prepared with various concentrations of green tea powder (0% (control group), 0.5% (GT-0.5 group), 1% (GT-1.0 group), 1.5% (GT-1.5 group), 2% (GT-2.0 group)), and their quality changes during storage were also investigated. The optimal mixing ratio of green tea powder, sugar, and water for preparing the best quality Seolgiddeok was 1.0%, 12%, and 22%, respectively. The proximate composition of green tea powder was 21.70% of crude protein, 8.49% of crude lipid, 2.95% of reducing sugar, and 6.40% of ash. The contents of crude lipid, reducing sugar, and catechins in Seolgiddeok added with a green tea powder were increased with increasing the content of green tea powder. The hardness and gumminess of GT-1.0 group were the lowest among four groups, whereas GT-1.0 and GT-2.0 groups had the lowest cohesiveness. While the control group was the lowest in adhesiveness, the springness was not significantly different among all groups. GT-0.5 and GT-1.5 groups were the highest in sweet taste and colorfulness, respectively. However, GT-1.0 group had the best overall quality. Total microbial numbers, the acidity and pH in Seolgiddeok during storage were decreased with increasing green tea powder content, and especially those of GT-1.0 and GT-1.5 groups were relatively the lower than others. The “L” value (lightness) of the control group (no additives) was the highest among five groups, and the value was decreased with storage period, and especially GT-0.5 groups had the lowest brightness. The“a”value (reddness) of the control group was the highest, followed by GT-0.5, GT-1.0, GT-1.5, and GT- 2.0 group in order. The“b”value (yellowness) was increased with the increase of green tea powder content. Above results indicated that GT-1.0 group showed the best quality of Seolgiddeok through organoleptic and rheology tests.

The quality characteristics of pudding products comprising of Korean Olbyossal (traditional steamed rice), added at different percentages, were examined to explore the application of Olbyossal to develop different types of processed food products. Five groups of pudding were produced containing 0%, 25%, 50%, 75%, and 100% of Olbyossal. Evaluation of their quality characteristics and antioxidant activities revealed that the control group (with no added Olbyossal) had the highest moisture content and pH (p<0.001). The sugar content and turbidity was highest in the 100% Olbyossal group and lowest in the control group (p<0.001). The salinity was lowest in the 100% Olbyossal group (p<0.001). In terms of color values, the L-value (p<0.001) and a-value were highest in the control group, while the b-value was highest in the 100% group (p<0.001). Texture properties revealed that hardness (p<0.001), springiness (p<0.01), and chewiness (p<0.001) decreased as the percentage of Olbyossal increased. Increase in adhesiveness was noted with an increase in the percentage of Olbyossal (p<0.01). Based on the sensory evaluation of Olbyossal pudding in terms of appearance (p<0.05), flavor (p<0.05), taste (p<0.01), texture (p<0.001), and overall quality (p<0.001), the 100% group showed the best results. Examination of Olbyossal pudding revealed that antioxidant activities, radical scavenging activities for DPPH and superoxide anion, and reducing power increased as the percentage of Olbyossal increased (p<0.001). Therefore, pudding containing 100% Olbyossal is considered as the ideal product with reference to the high level of preference and product quality.

This study has examined the 20's and the 30's Korean who have a desire, 'to be getting younger' and how to relate what appearance management-behavior they follow. The methodology of this study used both theoretical and quantitative research for an empirical study. First, a theoretical study researched a big stream of the 20's and the 30's Koreans' to be getting younger' on articles based on the social and cultural background of the past 30 years that defined various concepts of age through previous research. Data was also collected via SMS for five months (August to December 2014) and 96 Korean participants in their 20's and the 30's who have lived in and around Seoul. The results of the survey analysis showed that the desire of 'to be getting younger' irrelevant to the age among Korean young people. In addition, this tendency to be the ideal age as being younger is realized by appearance management sort of skin care or clothing styling among 20's and the 30's Korean. This study suggested a phenomenon, 'to be getting younger' in Korean society would lead to an alternative sort of age that targets individual taste rather than the chronological age in the apparel market.

The purpose of this study was to compare convenience food purchasing behaviors and food habits. The study, which asked surveyed 131 female college students in Daejeon, in 2011, on how they used nutrition labels. The subjects were divided into two groups, in terms of the way they checked examined nutrition labels: a "Check" group(n=62, 47.3%) and a "No check" group(n=69, 52.7%). Reasons given for not reading nutrition labelings were "a habit of buying" for 72.2%, and "too small or rude" for 19.1%. The "Check" group reported higher interest in nutrition(p<0.001) and hygiene(p<0.01) than the "No check" group. Those who used the labels had higher cereal(p<0.01) and vegetable(p<0.01) consumption and a lower intake of fast foods(p<0.05). But however, most of the subjects(65.6%) chose by taste, at the time they purchased the convenience foods. The subjects considered "expiry date"(n=87, 66.4%) to be more important information on food labels than "nutrient composition"(n=11, 8.4%). The number of products whose nutrition labels were checked by over 50% was five out of 12. In conclusion, our study suggests that proper use of nutrition labeling may improve food choices and enable healthy dietary practices. Further efforts are needed to provide the public with nutrition education programs on how to read nutrition labeling. Modifying nutrition labels to make them easier for the public to understand should also be considered.

Tomato sauce is widely known as a health food, In this study perilla leaf was added to a tomato sauce and the resulting functional improvements were assessed. The moisture of the tomato sauce WITH 2% added perilla leaf was 89.52%, the highest observed likewise, sample pH also significantly increased with 2% perilla leaf, to the highest pH of 4.71, (p>0.001). Lightness L value of the control group was the highest at 40.70, and the redness a value and yellowness b value were highest in, the control group, at 15.77, and 17.70, respectively. The highest salinity was foung with 2% perilla leaf, 0.96, and the sugar content with 2% perilla leaf, was 9.57. The reducing sugar was highest in the control with 63.08. The change in the total bacterial counts was measured during 9 days of storage at $4^{\circ}C$, When perilla leaf was added to, the tomato sauce, no microorganisms were detected until 0~1 days of storage. After five days of storage, microorganisms were detected in the group with 2% perilla leaf. The control group ($1.8{\times}10^5$ CFU/ml) had the highest levels of microorganisms. As the amount of perilla leaf, the total viable count of microorganisms detected was less. In the acceptability test results, the color 6.9 of the 1.5% treatment group, received the highest evaluation. Flavor and taste of the 2% perilla leaf treatment group were highly appreciated at 6.1 and 6.6, respectively. The ranking of overall acceptability was 1.5%>1%>0.5%>10%>2% of perilla leaf; 2% perilla leaf was the most underrated. Based on these results, up to 1.5% perilla leaf could be added to tomato sauce and the commercial potential could be very high.
