This nutritional survey was conducted from February 8 to March 10, 1994, in order to investigate the nutritional knowledge, food habits, nutritional attitude, food preferences and nutrient intakes of urban middle-aged women living in Daegu and Pohang district. The subjects of this survey were 164 urban middle-aged women living in Daegu and Pohang Area. The completely answered questionnaires were analyzed for nutritional knowledge, food habits, nutritional attitude, food preference and nutrient intakes of urban middle-aged women. The results obtained are summarized as follows: The subjects had a high level of perceived knowledge (82.9%), that is the knowledge that each subject believed she had, but the accuracy of the knowledge was only 66.1%. The average nutrition knowledge score was 8.26 out of possible 15 points, and food habit score was 5.50 out of 10 points. Most of the subjects belonged to 'Fair' or 'Good' food habit group, which is considered to be relatively good. With increasing age, the percentage of perceived knowledge, accuracy, and nutrition knowledge score were getting lower. But food habit score and nutritional attitude score were getting higher at 40's women than 30's women. The correlation between nutritional knowledge score and food habit score was low (r=0.0748). The correlation between nutritional attitude score and food habit score was low, too (r=-0.0653). Food preferences for kimchi, potato, cooked rice, beef, noodle, cabbage and milk were high. Average calorie and protein intake of the subjects were $1967.4{\pm}27.8\;Kcal$, $75.8{\pm}1.4\;g$ respectively. Carbohydrate, protein and fat ratio on energy composition was 63.3%:15.5%:21.2%.

This study was performed to provide fundamental data on the dietary life according to the acculturation degree. The subject was 305 Chinese students in South Korea region. The questionnaire respondents are consisted of 148 male students (48.5%) and 157 female students (51.5%). There was a statistically significant difference in age, education level, residence time, and Korean language ability according to acculturation degree (p<0.05), but there was no statistically significant difference in gender, residence pattern, purpose of coming to Korea. There was a statistically significant difference between meals frequency, outside frequency, and the intake of Chinese food according to acculturation degree (p<0.05), but there was no significant difference in snake taking frequency (p>0.05). There was a statistically significant difference in drinks and computer time according to acculturation degree (p<0.05), but there was no statistically significant difference between smoking and exercise (p>0.05). The food intake style of Chinese students was 2.47 in noodles, 2.34 in lunches and 2.15 in breads. According to the acculturation degree, the food intake patterns showed statistically significant differences in dumping kind, congee, hamburger and pizza, while meat products, smoked meat, noodle, lunch, cereal, kimbap, sandwich. And there was no significant difference. The correlation between the factors influencing the acculturation degree of Chinese students showed a statistically significant effect on dietary habits, food intake, education level, residence period, and Korean language ability.

The objective of this study was to examine the effect of acculturation stage on dietary intake of Korean American women (0=124) living in California and to compare the dietary intake with that of Korean women (0=191) in Seoul, Korea. The dietary intake of the subjects was collected by 24-hour recall method at cross-sectional surveys. Ouster analysis performed on immigration variables (e.g., length of residency, age at immigration, etc.) classified Korean American women into less (0=73) or more (n=51) acculturated group. Acculturation stage did not have a significant effect on macro nutrient intake. However, vitamin C intake was higher in the more acculturated group, while intakes of folate, calcium, iron, and zinc were higher in the less acculturated group. In comparison of three groups (the more and the less acculturated Korean American, and the Korean group), the more acculturated the women were, the less frequently they consumed rice and kimchi (p<0.05). Korean American women ate bread/noodle, meat/meat products, fruit juice, and soda more often and consumed vegetables less frequently, compared with Korean women (p<0.05). For breakfast, Western dishes were preferred in both more and less acculturated groups. Korean dishes were favored for dinner by both groups, even though the less acculturated group ate more Korean dishes than did the more acculturated group. The acculturation measured by immigration variables influenced nutrient intakes, food consumptions, and types of dishes eaten in Korean Americans. Cultural and health implications of dietary acculturation need to be studied in the future.

The aim of this study is to identify the value structure of active seniors for noodles. Noodles are the secondly most preferred and familiar food in Korea, followed by rice. And noodles also have a variety of tastes/flavors and even a variety of ceremonial characteristics. The necessity of offering proper food to seniors has recently increasing because Korea becoming an aged society. This study conducted 1:1 in-depth interviews with 30 active senior participants using the soft laddering technique, which is based on the means-end chain theory. The Implication Matrix and HVM were derived from performing content analysis. The active seniors mainly consider the 'taste', expecting to obtain the 'satisfying taste', and pursuing the 'family affair', 'pleasure', and 'self-satisfaction'. The results of this study indicated that the taste is the most important attribute and the active seniors consider their family as well as the pleasure and satisfaction of their own. Male seniors mainly pursue the 'pleasure' and 'self-satisfaction' by satisfying their taste through considering 'taste' and 'familiarity'. But female seniors mainly pursue the 'family affair' by 'satisfying taste' through considering 'taste'. These results can be used as a basic data for developing noodle products for the elderly. This study will also contribute to the development of special care food and product concepts for the silver generation.

Background: This study aimed to determine the effect of ramen sauce on tooth tone changes over time, after selecting three different ramen colors from the ramens sold in the market, and applying the sauce to bovine teeth. Methods: Healthy bovine teeth were selected, and cutting discs were used to produce 60 specimens (5× 5× 3 mm), with 15 specimens distributed per county. Three types of ramen (buldak, chacharoni black bean sauce, and ottogi curry noodle) were used as the experimental group, and water was used as the negative control group. Tooth tone measurement was performed using a spectrophotometer (CM-700d) to measure the color before and after 1 (3 h 44 min), 2 (7 h 28 min), 3 (11 h 12 min), and 4 weeks (14 h 56 min). Analysis of the color tone change was performed using Statistical Package for the Social Sciences version 28. Results: In the experimental group, there was a significant color tone change before and after immersion. L^* indicated the largest change in black bean sauce ramen, a^* indicated buldak ramen, and b^* indicated the largest change in curry ramen. The amount of color change (∆E^*) was the largest in curry ramen, followed by buldak and black bean sauce ramens. The results of the post-hoc analysis showed significant differences between all groups except buldak and black bean sauce ramens. Conclusion: All three types of ramen revealed significant color change before and after immersion, and curry ramen showed the largest amount of color change among them.

Some biological activities such as an electron donating capacity, the contents of total polyphenol compounds and flavonoids, fibrinolytic activity and $\alpha$-glucosidase inhibitory activity have been detected in hot water extracts of Ligularia fischeri and Angelica gigas Nakai. To increase the usefulness of the functional ingredients for prevention and improvement of some metabolic disorders, ethanol-treated hot water extracts of Angelica gigas Nakai were prepared. A hot water extract of Ligularia fischeri has 92% of electron donating capacity, 39.4 mg/g of total polyphenol compounds, 24.8 mg/g of flavonoids and 29.8% of $\alpha$-glucosidase inhibitory activity, but no fibrinolytic activity. A hot water extract of Angelica gigas Nakai has 94.7% of electron donating capacity, 5.8 mg/g of total polyphenol compounds, 2.6 mg/g of flavonoids, 0.48 plasmin units of fibrinolytic activity and no $\alpha$-glucosidase inhibitory activity. However, with partial purification using cold ethanol treatment, the $\alpha$-glucosidase inhibitory activity of Angelica gigas Nakai was increased to 70.5%. Thus, we expected a more useful effect with the use of the addition of a cold ethanol-treated Angelica gigas Nakai extract. The L, b values of cold buckwheat noodles using a mixture of 0$\sim$3% of Ligularia fischeri powder and 0.5% of an ethanol-treated hot water extract of Angelica gigas Nakai were decreased with the addition of an increasing amount of Ligularia fischeri powder. Among the mechanical qualities, only adhesiveness was significantly higher in 3% Ligularia fischeri noodles. From sensory evaluation data, it was determined that these two functional ingredients did not ruin the color, texture, and overall acceptance of the cold buckwheat noodles. A higher amount of the extracts improved the quality of the product with little added cost.

Whole wheat is rich in dietary fiber and contains various biological activity substances such as arabinoxylan, phytic acid and phenolic compounds. However, excessive fiber contents of whole wheat has a negative effect on dough formation, making it difficult to process. In this study, we tried to improve the usability of whole wheat by suggesting an appropriate degree of purification of whole wheat from 'Saekeumkang', a domestic wheat cultivar containing protein and gluten suitable for noodle production. The contents of arabinoxylan, phytic acid, and vitamin E were measured in the polishing rate range of 5-20% of whole wheat flour. As the milling ratio increased, the flour properties improved. The arabinoxylan and phytic acid content of whole wheat were 67.95 mg/g and 0.87 mg/g, but when milled at 20%, arabinoxylan and phytic acid were 60% and 80% of whole wheat, respectively. And as the milling ratio increased, the vitamin E content tended to decrease (whole wheat: 4.063 mg/100 g, 20% milled: 2.96 mg/100 g), However, the vitamin E composition ratio did not change. On the other hand, α-tocopherol showed the greatest than other vitamin E isomers. Therefore, further studies needed to optimize milling rate to improve the final product while maintaining the approximate nutritional and functional value of the whole wheat.

The influence of heat-moisture treatment (HMT) and substitution of rice flour containing different amylose contents on the quality characteristics of rice noodles was investigated. HMT was applied to rice flours with 21% moisture content at 100 and 105$^{\circ}C$ for 30 min. Three rice cultivars were used, including high amylose of Goami (GM) and intermediate amylose of Choochung (CC) as domestic rice flours and imported rice of Taeguk (TG) as a control. HMT and substitution of rice flour with different amylose contents affected the cooking and texture quality of rice noodles. When rice noodles were made of intermediate amylose rice flour with HMT, cooking properties improved with decreased cooking loss and cooking water turbidity and thus were closer to those of control. Especially, the hardness, adhesiveness, tensile strength, and darkness of rice noodles notably increased when HMT rice flour was used. Based on the results of quantitative descriptive analysis for selected rice noodles, the noodles made of HMT CC at 105$^{\circ}C$ (CC105) had high scores for resilience and adhesiveness and low scores for hardness compared with imported commercial rice noodles and other experimental noodles such as TG, HMT GM100, TG+CC, and TG+CC105. In conclusion, rice noodles were made of composite flours containing high amylose and intermediate amylose contents or HMT intermediate amylose content rice flour.

To understand the dietary culture in Poongki region which was established as Kamrokchon of a folk community, the transmission pattern of the traditional dietary life was investigated by questionnaire to 383 housewives, and the results are as follows : 1) Daily diet : Among 65 traditional main dishes of 6 areas including Kyungsangdo, D’cokguk of Kyungsangdo was consumed most frequently, 87%. General consumption rate based on origin of food was 33.3% of Kyungsangdo, 21.2% of Chungchongdo, 13.1% of Kangwondo, 11.9% of Hwanghaedo, 1.1% of Pyungando and Hamkyungdo, respectively. Among 243 traditional minor dishes, Doenjangjjigye and Kochuchang of Kyungsangdo were most consumed as rates of 91.6%, 89.3%, respectively. General consumption rate based on origin was in order of 38.4% of Kyungsangdo, 19.3% of Chungchongdo, 14.9% of Kwangwondo, 10.4% of Hamkyungdo, 8.7% of Hwanghaedo and 8.3% of Pyungando. 2) Special diet : Among 66 traditional D’ocks, Injeolmi of Hamkyungd was consumed most freguently, 58%. General consumption rate based on origin was in order of 26.3% of Hwanghaedo, 17.6% of Kyungsangdo, 16.1% of Kwangwondo, 16.0% of Hamkyungdo, 13.0% of Pyungando and 11.0% of Chungchongdo. Among 27 cookies, Kangjeong of Hamkyungdo was consumed most frequently 46.7%. General consumption rates based on origin was in order of 55.7% of Hamkyungdo, 22.7% of Kyungsangdo, 2.4% of Pyungando, 5.8% of Kwangwondo, 3.0% of Chungchongdo and 0.4% of Hwanghaedo. Among 19 refresh drinks, Kamju of Kyungsangdo was consumed most frequently, 76.0%. General consumption rate based on origin was in order of 74.3% of Kyungsangdo, 7.8% of Chungchongdo, 6.9% of Hamkyungdo, 5.9% of Hwanghaedo and 5.1% of Kwangwondo. 3) Ceremonial diet : Myyeogguk and Baeksulgi for the 100-Days ceremony and Hynbab and Baeksulgi for the First Birthday were used mainly. For birthday, noodle(59.5%) for lunch besides rice as main dish and Soojeoggwa(37.9%) were served and noodle(30.8%) was used for host. Thirty percent of the varieties used traditionally for Pyehak and 40-50% of the varieties for Jesa(Memorial day) are still prepared currently. 4) Seasonal diet : For Jeolsik(major seasonal diet), the usage rates are as follows : D’ockguk(87%) for Jeongwolchoharu, Ogokbab(77.6%) for Jeongwoldaeborum, Patjuk(72.6%) for Dongji, Samsaeknamul(54.1%) for Chusuk. Relatively high usage rates of Surichi-D’ock(40.5%) for Dano and Mandu(40.5%) for Suddalgumumnal are probably due to the immigrated people from this area and the geographical effect. The consumption rates of Sisik(minor seasonal diet) for Chunghwajeol, Samjinal, Youdooil, Chungyangjeol and Muoil are about 10% and the rates for Chopail and Chilsuk are followed. Gaejang and Nangmyon for Sambok used as a rate of 32%. 5) Others : Table pattern; Table for one person(4.7%), table for two(16.7%), table for several(64.2%), table with chair(14.4%) are used. Serving pattern; All-together style(69.7%), monopoly style(24.0%), personaldish style(6.3%) are used. Cooking ware; Among 95 varieties, Doma and Jangban are used most(62.7%) and Pulmae, Poonju and Budulgori are never used. Nine sorts besides Jeongoltle are used as a rate of less than 1%. About 25% of total subjects were the immigrants from other areas. Some of them were moved in due to Chunggamrok. In conclusion, the usage of the traditional food is thought to be maintained well despite of the rapid change to incustrialized society because the native Kyungsangdo foods are combined with foods from the neighboring Kwangwondo, Chungchongdo and northern area.
