Seoung, Tae-Jong ; Choi, Soo-Keun ; Byun, Gwang-In ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 667~680
The moisture contained in conventionally extracted red crab shell samples was lower than than in samples extracted using high pressure. In contrast, ash content increased as the extraction time increased and displayed no significant variation in high pressure extraction. Extraction time was influential, with lower lightness (L-value) being obtained in samples extracted at high pressure as compared to traditional extraction. However, large variation in a- and b-values resulted from traditional extraction. For both traditional and high pressure extraction increases in pH, salinity and saccharide content were noted with increasing extraction time, but these parameters did not vary substantially in red crab shell extracted at high pressure. The mineral content in samples extracted by high pressure was higher than in traditionally extracted samples. The mineral content increased with time, with marginally higher contents of essential amino acids and flavor enhancing amino acids noted following high pressure extraction. The contents of the flavor enhancing amino acids increased from 30?60 min, thereafter decreasing. Assessment of consumer acceptance revealed that, while traditionally manufactured red crab sauce was popular, sauce manufactured using a 60 min high pressure extraction was preferred. Extending the high pressure extraction time to 75 min produced a less sensory acceptable product, due to higher mineral and protein levels.

Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 681~692
The principal objective of this study was to assess the bone density and processed food intake behavior of middle-aged and elderly women in the Seoul area. The subjects were assigned to one of the following groups on the basis of BMI: namely, the underweight, normal, and overweight groups. The results are summarized as follows: The average BMI and systolic blood pressure of the three groups were 19.0, 127.3 mmHg; 22.4, 132.8 mmHg; and 26.8, 136.1 mmHg respectively. The BQI and T-scores of the three groups were as follows: 56.6, -2.50; 62.3, -2.22; 66.0, -2.03 respectively. The bone status of the three groups, in terms of the percentage of normal and osteoporosis, were 9.5%, 52.4%; 8.3% 33.0%; and 8.8%, 23.6% respectively. We noted no significant differences in processed food intake (frozen, cold and can processed food, instant and convenience store food, basic side dishes) behavior among the three groups. However, we recorded a negative value between processed food intake and bone density (BQI, T-score, %young adult, Z-score, %age-matched) generally. In particular, ramyeon (r=-0.1574, p<0.05) and cup-ramyeon (r=-0.1996, p<0.05) intake were significantly associated with the T-scores of bone density levels. The results of this study revealed that processed food intake was not generally desirable for healthy bone. Thus, practically and systematically organized education regarding a good and healthy dietary life is highly recommended.

Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 693~704
In this study, the preference for Korean Kimchi by Chinese people in Shandong Province was evaluated. Specifically, this study was conducted to aid in the introduction of Kimchi to China by providing information and developing local types designed to meet regional taste preferences. The subjects were comprised of 298 Chinese (male 108, female 190) residents of Weihai, Yantai and Qingdao, in Shandong province, China. The subjects were provided with a self administered questionnaire form designed to evaluate their views on Korean Kimchi. The collected data were then analyzed using the SAS software package. The results revealed that 95.3% of the respondents were aware of Korean Kimchi. In addition, 100% of the respondents who had visited Korea and 98.1% of the respondents who had an interest in Korea were aware of Kimchi. With regard to the origins of their interest in Kimchi, 26.8% of the subjects answered 'through mass media', while 23.9% reported that they learned about Kimchi 'through friends'. Most subjects recognized Kimchi as a 'Korean traditional food' (92.6%), a 'delicious food' (53.2%), and a 'fermented food' (38.0%). Baechu Kimchi was found to be the most well-known Kimchi, followed by Kkakdugi, Oi Kimchi, Yoelmu Kimchi and Nabak Kimchi. Additionally, 69.1% of the subjects knew how it was prepared, most of whom reported that they learned how Kimchi was prepared through 'Korean movie and/or drama'. Moreover, 88.9% of the subjects had eaten Kimchi. Overall, 43.8% of the subjects reported that they ate Kimchi
times per month, while 32.1% reported that they ate Kimchi
time per year. The most common places that Kimchi was eaten were a 'Korean restaurant' (67.6%) or with a 'colleague' (32.8%). The primary reasons for not having eaten Kimchi were 'no knowledge or dislike of Kimchi by family' (30.3%), 'difficulty purchasing Kimchi' (21.2%), 'high priced Kimchi' (21.2%), and 'dislike the smell and shape of Kimchi' (12.1%).

Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 705~712
In this study, Jeonju bibimbap, Bulgogi, Japchae, Whangpomuk, Kimchijeyukbokkeum, and Sangseonjeon were selected as examples of take-out style Korean foods, and sensory evaluations on a 9-point hedonic scale were conducted with dining staff at UCLA. 54.5% of the respondents in this study were male and 62.7% were Hispanic/Latino, with the respondents fairly evenly split across age groups in a range of 25-54 years. In the sensory evaluation, the most acceptable items were judged as follows: Bulgogi (8.1)>Japchae (7.5)>Sangseonjeon (7.4)>Jeonjubibimbap=kimchijeyukbokkeum (7.3)>Whangpomuk (6.9). Among the 6 Korean foods (Jeonjubibimbap, Bulgogi, Japchae, Whangpomuk, Kimchijeyukbokkeum and Sangseonjeon), Bulgogi, and Saengseonjeon were the most acceptable items for the female and male respondents, respectively. All of the items were popular with the majority of the responding age groups, with the exception of the 18-24-year groups; in particular, Kimchijeyukbokkeum and Bulgogi scored relatively high on acceptability (7.0) for all respondents. Jeonjubibimbap, Japchae, Whangpomuk, and Saengseonjeon were also found to be acceptable to all respondents except for the African American respondents. We suggest that the Korean foods listed above are applicable items for quick service restaurants in the U.S. market.

Lee, Eun-Young ; Cho, Mi-Sook ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 713~719
The purpose of this study was to investigate the food preference and attitude according to six emotions in female university students. Also, it was studied whether the desire to food consumption was changed by each mood. The selfreported questionnaire was used to 285 female university students. There were the significant differences in food preference according to emotions. Pizza & pasta, ice cream and cake were preferred during happiness and amusement. In sadness and anger, alcohol was the most preferred food item. There was the preference of beverage, Jjigae & Baikban, ice cream and snack during relaxation. Chocolate showed the highest preference during depression. The taste and flavor was the main preference attributes during all emotions. The self-assessed food intake during happiness, amusement, anger and relaxation was increased but it was decreased during sadness and depression (p<0.001).

Kim, Maeng-Jin ; Chong, Yu-Kyeong ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 720~728
The objective of this article is to examine Korean consumers' perception level of the country-of-origin of brand (COB) of global restaurant franchises. Although global brands have rushed onto the Korean food service market since 1980, there has been little or no research conducted regarding consumers' perception of COB of global restaurant franchises. In this study, we surveyed consumers to determine their perception of COB for 27 foreign global restaurant brands; specifically, we attempted to determine whether or not Korean consumers could correctly recognize the COB of each brand. The results of this research revealed that Korean consumers correctly perceived the COB of certain restaurant brands, and incorrectly perceived some other brands. For instance, Korean consumers' perception level of the COB of McDonald's and KFC were quite high, and conversely their perceptions of the COB of Outback Steakhouse and Pohoa were relatively low. When consumers select a restaurant brand, COB image was shown to be more influential than brand image.
Globalization of Korean Cuisine through the Korean Food Items Promotion -Focus on Marketing Strategy of Korean Food Items-
Lee, Eun-Jung ; Kim, Tae-Hee ; Kim, Doo-Ra ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 729~736
The study sought ways to promote the global recognition of Korean food items. The Korean cuisine is one of the healthiest and well-balanced in the world. But, in contrast to countries including the United States, France, China, Japan, Thailand and Australia that have adopted food promotion and marketing strategies, Korea lacks a similar strategy. Development of indigenous sauces by Korean food manufacturers and processors is one route in the promotion of Korean cuisine. Korean restaurant franchising could also aid in export of Korean food items. The food manufacturing/processing sectors must work in concert with the Korean government to globalize the Korean cuisine. Brand chefs, Korean cuisine seminars and promotional efforts in foreign countries and foreign cooking schools (such as the 'Taste Korea' campaign) are prudent actions.

Lee, Youn-Suk ; Park, Mie-Ja ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 737~747
This study was conducted to investigate the perception and understanding parents had regarding environment friendly agricultural products being used for school foodservice. A trained practitioner surveyed 221 parents of children at elementary schools in Daejeon using a questionnaire, after which the resulting data were analyzed by a Chi-square test. Overall, the parent's responses regarding the foodservice were positive. However, most of the parents do not participate (65%) in the school foodservice if they work, and those that do participate primarily work as meal service aides (58.1%). Parents indicated that the work of urgent field of inspection on food materials (69.9%), and the reason of an agreement (98.2%) for them were the students' health (68.4%). In addition, most parents were positive about the possibility of replacing foods used in the school with environment friendly products (51.6%) and felt that the government should pay the additional expense associated with their replacement. Furthermore, the majority of the parent's surveyed felt that children should be supplied with vegetables (54.9%) purchased directly from farms. The parents' satisfaction with the meal service (25.1%) was lower than that of the students (54.1%). The reason for the satisfaction reported by the parents was concern regarding the health of their children (53.3%). In addition, the majority of the parents (47.3%) responded that environment friendly agricultural products differ from general agricultural products because insecticides and fertilizer were not used. The main objection parents had to using environment friendly products was their cost (59.1%), and most parents felt that a realistic solution to this problem was unified purchase (41.4%). Besides, a problem when replacing with them was the expensive price (38.1%) and true or false (37.7%), and the students' satisfaction (59.5%) was selected the most in an effect of using them, diversity of the product (39.1%) and price reduction (32.6%) for a solution of the increase of using them.

Park, In-Duck ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 748~754
The principal objective of this study was to evaluate the quality characteristics of pound and sponge cakes prepared with Cucurbita maxima Duchesne (C. Maxima Duch.) puree, via physical and sensory examinations. The cakes were formulated by repalcing the egg with C. maxima Duch. puree at concentrations of 0, 10, 20 and 30%. C. maxima Duch. puree contained 87.91% water, 0.58% ash, 1.68% protein, 0.55% lipid, 1.02% fiber, and 8.26% carbohydrate. The physicochemical properties of the pound and sponge cakes evidenced similar patterns. The specific gravities of the pound and sponge cakes increased with increasing substitution levels, whereas the specific volumes were reduced. The hardness values of the pound and sponge cakes containing the C. maxima Duch. puree were higher than those of the controls. Substituting C. maxima Duch. puree for egg resulted in reduced lightness and increased redness in the cakes. Pound and sponge cakes with C. maxima Duch. puree evidenced higher moisture contents than the controls over 5 days of storage. Overall acceptances in sensory evaluation scored higher in the 20% substituted pound and sponge cakes.

Son, Chan-Wok ; Kim, Hye-Jeong ; Lee, Yun-Jin ; Kim, Mee-Ree ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 755~760
This study was carried out to investigate the quality characteristics and antioxidant activity of the black sesame Dasikadded spirulina (0, 10, 20, 30%). Black sesame Dasik with 30% spirulina showed a higher moisture content compared to control. L, a and b values of Hunter color system were decreased significantly according to the addition of spirulina (p<0.05). Hardness and gumminess analyzed by TPA (Texture profile analyzer) were increased significantly according to the addition of spirulina (p<0.05). The antioxidant property of black sesame Dasik increased according to the addition of spirulina: IC50 values of DPPH (1,1-diphenyl-2-picrylhydrazyl) and hydroxyl radical scavenging activity of the control was 112.3 g/mL and 56.2 mg/mL, respectively, whereas those of Dasik with 30% addition of spirulina was 58.2 mg/mL and 45.7 mg/mL, respectively. Sensory evaluation results showed that the overall acceptability was not significantly different up to 20% addition of spirulina, compared to that of the control. Based on these results, it was suggested that the addition of spirulina to black sesame Dasik was appropriated up to 20% for quality improvement with antioxidant activity.

Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 761~770
The purpose of this study was to determine the optimum amount of four ingredients (spirulina, sugar, lemon and orange) for the preparation of spirulina madeleine using response surface methodology. Spirulina was added at a level of 3.5-6.0 g, sugar powder, at 40-60 g, while lemon and orange peel were included at a level of 0-8 g. The optimum mixing rates of spirulina powder, sugar powder, lemon and orange were 3.5, 40, 0, and 8 g for overall quality and 3.52, 54.42, 0, and 8 g for maximum score of overall organoleptic quality, respectively.

Cho, Hee-Sook ; Kim, Kyung-Hee ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 771~778
This study was conducted to investigate the quality characteristics of cookies prepared using skate powder (0, 1, 3, 5, 7%) as a substitute for flour. The pH of the cookie dough decreased significantly in response to the addition of all levels of skate powder. However, there were no significant differences in the dough values among the test groups. Furthermore, when the spread factor values were compared among groups, they were found to be inversely proportional to the skate powder concentration. In addition, the Hunter's color L, a and b values decreased significantly as the level of skate powder increased. Moreover, the addition of 1-7% skate powder resulted in increased hardness, cohesiveness, springiness, and brittleness when compared to the control. Finally, the results of the sensory evaluation and acceptance test showed that the cookies containing 3% skate powder had the highest scores.

Yim, Kyeong-Sook ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 779~792
The consumption of a wide variety of food groups is considered one of the key components of nutritional adequacy. The 2005 Dietary Guidelines for Koreans includes the consumption of a variety of foods from diverse food groups as a component of a normal diet. A survey was conducted to evaluate the relationship between the dietary diversity of food groups and nutrient intake in elderly patients (age 65 and above) at a rural area in Korea (Inje). 296 subjects (111 male and 185 female) were probed in a 3 day 24-recall dietary survey. Subjects were grouped according to food group intake frequency, based on six food groups (grain, meat/fish/legume/egg, vegetable, fat/oil, dairy, fruit). Nutritional quality was evaluated according to the numbers of nutrients under EAR (Estimated Average Requirements), and MAR (mean adequacy ratios). The frequency of elderly subjects consuming a meat/fish/legumes/egg food group less than once per day was 29.4%. The frequency of elderly subjects consuming fat/oil food group less than once per day was 65.8%. The percentage of subjects who did not eat dairy food was 88.8%, and that of subjects who did not eat fruit was 57.5%. A stepwise multiple regression analysis was used to develop models relating nutritional quality to possible food group intake frequency factors. Using the number of nutrients under EAR as a dependent variable, the meat/fish/legume/egg food group intake frequency explained 9.9% of variance, followed by the grain group, fat/oil group, dairy group, and vegetable and fruit group (Model
=0.260). For mean nutrient adequacy ratio as a dependent variable, the model
was 0.326. The results of this study suggest that a highly varied diet in elderly might be associated with better nutritional quality, as assessed by nutrient intake. Accordingly, dietary guidelines should take into consideration nutritional characteristics in order to improve intake from all major food groups and to provide a variety of foods in the diet.

Seo, Ju-Young ; Lee, In-Sook ; Choi, Bong-Soon ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 793~800
This study was conducted to evaluate the food habits and nutrient intake of preschool children by investigating their food and snack consumption. To accomplish this, a food habit questionnaire and dietary intake survey was administered to 148 children between 2 and 6 years of age (average 4.8 years). According to the Kaup index, the underweight, normal, overweight and obesity levels of the subjects were 4.7, 60.1, 26.4, and 8.8%, respectively. In addition, the total energy intake met the EAR (
), whereas the protein, iron, phosphorus, vitamin B and vitamin C levels exceeded the EAR and the RI. Furthermore, the nutrient intake profile revealed that the mean caloric value of breakfasts consumed by preschool children in Daegu (403 kcal) was significantly (p<0.001) higher than that of preschool children in the Gyeongbuk area (271 kcal). Additionally, preschool children in Daegu (
) usually consumed significantly (p<0.01) less food than those in the Gyeongbuk area (
). The preferred snacks among subjects (in descending order) were milk, bread, fruit, potato or sweet potato and cookies. The mean score of the Food Habit was
out of 5, although the score of preschool children in Daegu (
) was significantly (p<0.05) higher than that of children in the Gyeongbuk area (
). Taken together, these results indicate that there were significant differences in the Food Habit and nutrient intake level of children in Daegu and the Gyeongbuk area. Therefore, parents and caregivers should be aware of the importance of the nutritional status of preschool children and choose healthy snacks for them.

Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 801~811
The principal objective of this study was to assess the effects of soy isoflavone supplementation on bone mineral density in 36 female college students with osteopenia for 12 weeks. The subjects were divided into three groups on the basis of bone mineral density. The experimental groups were provided supplements of either 80 mg of isoflavone (Iso-80) or 40 mg of isoflavone (Iso-40). To the placebo group, 40 mg of powdered glutinous rice was administered. It was determined that many subjects with osteopenia evidenced lower levels of activity as compared to the control group. Isoflavone supplementation was more effective in controlling total cholesterol and LDL-cholesterol than was observed in the placebo group. We noted no significant differences in serum osteocalcin concentration between Iso-40 and the placebo group, but significant differences in osteocalcin concentration were detected between Iso-80 and the placebo group. Bone quality indices (BQI) were correlated positively with mineral content, lean body mass, muscular mass, and blood components including albumin, Ca, Mg, ALPase, and osteocalcin. Both Iso-40 and Iso-80 supplementation for 12 weeks significantly increased protein and mineral content in the body. As lower intakes of Ca and folate were noted in the subjects, emphasis should be given to adequate intakes of these nutrients in the subjects. In conclusion, 12 week isoflavone supplementation in young females with osteopenia exerted positive effects on bone mineral density and bone turnover markers.

Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 812~819
In this study, we assessed the effects of dietary supplementation with Ecklonia cava on blood glucose, lipid metabolism, and renal oxidative stress in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into a normal rat group fed on a control diet and diabetic rats fed on a control diet or supplemented with powder (15% w/w) or water extract of Ecklonia cava (2.5% w/w). Diabetes was induced by a single injection of STZ (60 mg/kg, ip) in citrate buffer. The animals were fed ad libitum with the experimental diet and water for 5 weeks. Dietary supplementation of Ecklonia cava powder and water extract was shown to reduce blood glucose levels in the diabetic rats, and the water extract was more effective than the powder. Dietary supplementation with Ecklonia cava also reduced LDL cholesterol and increased HDL-cholesterol levels in the diabetic rats. Renal glutathione S-transferase activity was increased in the diabetic rats as compared to the normal rats, but reverted to near control values as the result of dietary supplementation with Ecklonia cava. These results show that Eklonia cava exerts an anti-diabetic effect by improving blood glucose concentrations, LDL/HDL-cholesterol ratios, and antioxidative effects on the kidney in diabetic rats.

Jwa, Hea-Jin ; Chae, In-Sook ;
Journal of the Korean Society of Food Culture, volume 23, issue 6, 2008, Pages 820~833
The study analyzed the body shape perception, weight control attitude, nutrition knowledge, and dietary habits of 529 high school students in Jeju surveyed from January 14-18, 2008 according to students' body shape satisfaction, with the aim of providing basic nutritional education data to aid in appropriate weight control for high school students. The data were analyzed by descriptive analysis, T-test, Chi-square test, ANOVA, and Pearson's correlation coefficients, using the SPSS Win 12.0 program. The body mass index (BMI) of subjects was in the normal range. With regard to weight distribution, 59.4% of subjects showed normal weight and girls were significantly more underweight than boys. More girls considered themselves to be fatter than boys and tended to be increasingly dissatisfied with their body shape. Both boys and girls were more interested in weight control for obesity and were significantly less satisfied with their body shape. Efforts at weight control and reduction had occurred significantly more often for girls than for boys. Dietary attitude scores were significantly higher in girls than boys. BMI positively correlated to weight control concern and nutrition knowledge positively correlated to dietary attitude. BMI negatively correlated to the body shape satisfaction, which in turn negatively correlated to food ingestion disorders. Therefore, it is necessary to develop a systematic nutrition educational program that can induce changes in dietary behavior and increase accurate perception and satisfaction of body shape.
