Food consumption patterns are predictors of nutritional status at all age levels and vary among and between different age groups. This study was designed to asses food habits and fast food eating patterns of college students in Ulsan area through questionnaries. Data from 330 useable forms was analyzed for percent differences, frequency of consumption, and statistical significance of differences between male and female students (T-test and chi square methods were utilized). Food habit score of female students was significantly higher than of male students. The reason for using fast food chain was 'convenience' or 'good taste'. The most preferred food by subjects was noodle or dumpling and least preferred food was pizza. In general, they had a higher satisfaction scores in taste and service of fast food and lower scores in amount and price of it. From this results it appears there is a need for developing domestic brand fast food to lower the price of fast food and giving the nutrition education for proper food selections and eating patterns.

The study is being conducted to investigate the perceptions and preferences of the Korean kimchi by the Chinese international students in Jeonbuk area. Self-administered questionnaires were collected from 197 male (48.9%) and 203 female (51.1%) students. Statistical data analysis is being completed using SPSS v. 12.0. Approximately 95% of Chinese female and 91% of male students know about kimchi before coming to Korea through the Korean movies and dramas. The perceptions for kimchi according to the residence period showed a significantly difference 'kimchi is a nutritious and health food' (p<0.05), 'kimchi has good taste but too hot to eat' (p<0.05), and 'Kimchi is difficult to eat because of the smell' (p<0.05). Approximately 52% of Chinese female and 44% of male students consumed kimchi once or twice a day. The most popular form of kimchi among the 13 varieties was baech kimchi. Chinese female students preferred the 'kkakdugi' (p<0.05), 'chonggak kimchi' (p<0.05), and 'young radish kimchi' (p<0.05) more than the male students. The most liked reason was the 'refreshing taste' (44.8%) whereas the most disliked reasons were 'unfamiliar with eating kimchi' (28.7%) and 'sour taste' (24.2%). Approximately 85% of Chinese female and 60% of male students would like to experience making kimchis by themselves. Extended kimchi consumptions for Chinese answered 'not too fish-like smell' (36.0%), 'not too overly-ripe' (34.5%), 'not too sour' (25.4%), and 'not too hot' (25.4%). Therefore, in order to improve the awareness for kimchi among Chinese students, we need to relate kimchi with the taste of Chinese traditional foods.
This study investigated the effects of mashed maesil and maesil extract on Kimchi during fermentation. The mashed maesil and maesil extract were added at 5% of the weight of salted cabbages to the Kimchi sauce, and then physiochemical and sensory characteristics were examined over 28 days of fermentation at 4$^{\circ}C$. During the entire fermentation process, the mashed maesil Kimchi had a consistent pH of 4.4 to 4.2, and the mashed maesil controlled fermentation better than the maesil extract. The mashed maesil Kimchi had the lowest acidity ($0.43{\pm}0.01{\sim}0.42{\pm}0.01$), despite showing a similar pH level to the maesil extract Kimchi. The mashed maesil Kimchi presented the highest hardness level. And in the early stage of fermentation the control Kimchi had the lowest hardness; however, at the end of storage, hardness increased in every Kimchi and no differences were shown. In terms of color value changes, the L-values of every Kimchi increased as the fermentation period increased; but on the $28^{th}$ and final day of fermentation L-values had decreased in all groups. The group with mashed maesil had the highest a-value, but there were no significant differences in b-values among the groups. In evaluating sensory characteristics and acceptability of flavor, the maesil extract Kimchi was higher in intensity with regard to sourness, umami taste, sweetuess, maesil taste, carbonated taste, and fresh taste; it also had higher overall acceptability. Therefore, a fixed amount of maesil extract(5%) can be added to Kimchi with good affects on quality, by controlling fermentation and increasing flavor.
This study examined low calorie sweeteners (fractooligosaccharide, xylitol, erythritol, agave syrup, stevioside) instead of sugar for $Teriyaki$ sauce to satisfy customers' health needs. After adding sugar, stevioside, agave syrup, erythritol, xylitol, and fractooligosaccharide to $Teriyaki$ sauce, we measured moisture and viscosity. According to the results, the sauce with stevioside had a low moisture content, but its value was the highest in viscosity. The sauce with xylitol had average sweetness equal to that of sugar, but its salinity was very low. There was no significant difference in pH value. The difference in sweet taste showed that the sauce with xylitol met the requirement of sweet taste, soy sauce flavor, taste and savory taste. Therefore, xylitol was a good ingredient for $Teriyaki$ sauce.
A type of Korean traditional cookies, yackwa is composed of ingredients which serve as good medicine to people. Further, it has a priceless value and possibility to be a healthy functional dessert. For this study, we developed variable yackwa, containing red-ginseng powder and green tea powder, in order to target the foreign market as well as to investigate the perception and preference of yackwa. The test sample for the control group, yackwa is made of flour, sugar, baking powder, sesame oil and alcohol. For the experimental group, yackwa contains red-ginseng and green tea powder (3, 6, 9, 12%). The investigation period was May 14th, 2013 and the total number of participants was 100. The investigation applied a consumer survey method by filling out a questionnaire while tasting 9 kinds of yackwa samples. They were used for frequency, one-way ANOVA and Pearson's correlation analysis with SPSS 19.0. In the yackwa perception survey, the result indicated that 52.0% of the customers replied 'Do not know well' and 'Do not know at all' which conveys that the perception of yackwa is very low. In contrast, the perception of the red-ginseng and green tea which are functional ingredients is high and the customers tend to prefer the taste and flavor of green tea than red-ginseng. And they prefer the yackwa containing 3% of red-ginseng and green tea powder compared to other ratio contents in the overall preference, color, taste, flavor, odor, degree of greasiness and texture. When people who have a higher perception of yackwa, they tended to prefer the color of red-ginseng yackwa and dislike the color of green tea yackwa. And the more people prefer the taste of green tea, the higher in overall preference, color, taste, flavor, and odor preference.
The aim of this study was to develop a convenient brown sauce product with long shelf life that has similar taste and quality characteristics with sauce used in restaurants. Response surface analysis was carried out to optimize brown sauce. Extracted brown sauce powder was subjected to hot air drying, infrared drying, freeze drying, and spray drying to determine the appropriate drying method for brown sauce manufacturing. The optimum extraction conditions were set by superimposing and reading each reaction surface that satisfied all of the sensory characteristics such as color, smell, taste, concentration, and overall preference level in order to set the optimum conditions for brown sauce production. The optimum extraction conditions for brown sauce were determined to be heating time 30 min, gelatin addition quantity 9.00%, and tomato paste addition quantity 11.25%. Reliability test showed a similar value to the predicted scope when compared to the experimental value obtained under the same conditions as the predicted value according to RSM (response surface methodology), enabling verification of the derived regression formula. Product powder of ideal brown sauce by heating, infrared radiation, freezing, and spray drying and investigate result for functional tests of color, flavor, taste, viscosity, overall acceptability and show highly acceptability on powder by infrared rays and freeze-drying methods. Especially, infrared radiation method resulted in favorable color and flavor values while freeze-drying method produced good taste and viscosity values and high overall acceptability. Therefore, infrared radiation drying method and freeze-drying method to product powder.
This study was desingned to investigate the relationships between bone mineral density(BMD) of the lumbar spine($L2\rightarrowL4$) and menopausal symptoms, health conciousness, bone health status, activity intensity, preference of food saltiness in 41 postmenopausal women. Lumbago was main menopausal symptom, and BMD of the subjects with lumbago was significantly low compared with BMD of the subjects without lumbago(p<0.01). BMD of the subjects who felt healthy was significantly higher than BMD of them who felt inbetween or weak(p<0.05). BMD of the subjects who had good bone status of the lumbar spine was significantly higher than BMD of them who had bent lumbar spine or experienced bone fracture(p<0.001). BMD of the subjects who were active was significantly higher than BMD of them whose activity was moderate or sedentary(p<0.05). BMD of the subjects who preferred very insipid taste was significantly high compared with BMD of them who preferred insipid, moderate or salty taste, and BMD of the subjects who preferred very salty taste was significantly low(p<0.01). This study suggested that decrease of BMD of the lumbar spine was significantly related to lumbago, bone fracture and bent lumbar spine. And when they were active and not preferred salty taste, bone loss of the lumbar spine was decreased.
This study was performed to investigate gruel intake, preference and opinions about gruel development to produce new products for breakfast. The subjects of this study were 307 adults in Chungju city. People who favored gruels were 212(69.5%) and 50.2% of the subjects liked the gruel because of good digestion and absorption. They liked midium thick or thin gruel and also liked grain granules with some stuff as contents. The gruels often taken were abalone gruel(45.9%), pumpkin gruel(41.7%), chicken gruel(34.9%), vegetable gruel(33.6%), beef and mushroom gruel(30.3%) etc. in order. The frequency of gruel intake was 1-2 times/year and 59.6% of subjects got gruels from the special gruel restaurant. People who need gruels most were patients, indigestible person, the elderly, weaning babies, workers and students missing breakfast in order. Sesame taste obtained the highest score of all, that of bitter taste was significantly higher in over fifty year old people (p<0.05), and hot taste score was significantly higher in 30-40 year old people (p<0.01). The gruels preferred most were abalone gruel, pumpkin gruel, chicken gruel, beef and mushroom gruel, vegetable gruel, red bean gruel, pine nut gruel, egg gruel, sesame gruel, plain grain gruel etc. in order. Fifty seven percent of subjects wanted to develope new gruels fortified nutrients. In conclusion, when the substitute gruel for breakfast is developed, it is better to use food materials to be easy to digest, to have grain granules with some stuff inside and to be sesame taste.
Salt-fermented fish and fish sauce are very important materials to make Kimchi. They provide good taste and plenty of nutrition to Kimchi during fermentation. However, it is difficult to purchase Korean salt-fermented fish or fish sauce out of Korea. Therefore, to generalize Kimchi for other countries, this research carefully compared the quality differences between Kimchi made with South East Asian fish sauce, which is fairly similar to traditional Korean salt-fermented anchovy extract (Aekjeot) in terms of taste and ingredients, and that made with traditional Korean salt-fermented anchovy extract. To determine quality differences among traditional Korean Kimchies made with different sauces, Korean-made salt-fermented shrimp, salt-fermented shrimp extract, salt-fermented anchovy and salt-fermented anchovy extract were used. Of the four Kimchis, the one made with salt-fermented anchovy extract was chosen as a control sample and compared with those made with three different South-East Asian fish sauces. In the sensory evaluation for acceptance of fish sauces, characteristics of taste, texture and overall acceptance showed significant differences. In the sensory evaluation for differences, characteristics of fish odor and crunchiness showed visible differences. For umami taste, all fish sauces received higher points than Korean salt-fermented anchovy extract (control sample), although the difference was not significant. Sensory evaluation and research results show that Kimchi can become a highly likable food overseas and Kimchi can substitute easily bought South-East Asian fish sauces for Korean salt-fermented fish sauces (Jeotkal).
What satisfies the desire of human beings about taste most easily is sweet taste, and it has seemed that the pronoun of sweet taste is sugar. Sugar is used in confectionery and bread-making essentially, and it has influence on the structure and touch of baked confectionery. In addition, if we soften the and apply heat, coloring is made. Thus, it colors good. It doesn't have a sweet taste, but it has the effect to emit fragrance variously, balance and soften the product. The kinds of sugar are very diverse, and it is sugar to be referred to as white sugar is used most frequently. In this study, this researcher examined the classification of physicochemical property and melting point etc. of sugar in confectionery and bread-making through theoretical study, about the simple classification of sugar. In addition, this researcher approached about the role of sugar in confectionery and bread-making and about the influence to have when it is more or less than proper quantity, centering around function. As the result, this researcher extracted the importance of sugar in confectionery and bread-making. It means that the increase of 5% of sugar quantity decreases the absorption quantity of moisture by 1% in bread-making and that the excess of 8% of sugar slow the action of yeast in straight method. Besides, there are the properties such as absorptive property, permeability, storage nature, aging prevention of starch, oxidation restraint of oils and fats, the gelation action of pectin, the fermentation acceleration of yeast, and the emulsification-maintaining-nautre and antiseptics effect of fat-soluble material. And in confectionery, sugar makes fragrance and peel color, increases the storage nature with moisture maintenance and has the softening effect. So, it is considered that the attitude to study and make efforts continuously on the basis of the role of sugar will have to be unfolded in confectionery and bread-making.
