This study evaluated on the purchasing patterns for bakery products and the effects of brand image on consumers' purchasing power while living in the Seoul area. The questionnaires developed for this study were distributed to 400 males and females aged 20 and older. A total of 385 questionnaires were used for analysis (96.0%) and the statistical analysis, descriptive analysis, and $x^2$-test were completed using SPSS (version 14.0) software. When purchasing bakery products, 'taste' (59.7%) was most important followed by 'shape and size' (13.2%), 'ingredients' (11.7%), 'price' (7.5%), 'expiration date' (5.2%). 'origin of ingredients' (2.1%), and 'packaging' (0.5%). Subject showed significant differences in their purchase of bakery products based on characteristics including 'age' (p<0.05), 'occupation' (p<0.01), 'type of family' (p<0.01), and 'income' (p<0.1) The most influential factor in purchasing bakery products was 'material' (score=3.73), followed by 'name value' (score=3.56). Brand image of bakery had an effect on bakery products as 'present' (score=3.83), 'sanitation' (score=3.58). And, the most high respondent in basis of deciding brand image consumer's was 'clean and nice interior'(53.1%), followed by 'high quality ingredients and packaging'(23.7%).
Brown sauce is very frequently used for western meat dishes, and this study aims to develop brown sauce for Asians and Koreans by adding jujube concentrate which has natural sugar and is used in Chinese medicine. The ingredients and sensory characteristics of brown sauce added with jujube concentrate were examined and the results are as follows. First, the moisture content increased with increased amount of jujube concentrate added, while the pH decreased. In the results of the sensory evaluation, the sample added with 5% jujube concentrate had the highest score, and the one added with 9% jujube concentrate had the lowest score in color. In the flavor evaluation, the sample added with 5% jujube concentrate had the highest score, and the one added with 9% jujube concentrate had the lowest score. In overall acceptability, the sample added with 5% jujube concentrate had the highest score, and the scores were high in order of 3%, 7%, and 9% concentrates when the samples were heated for 16 hours. Also, when making brown sauce made with beef leg bones, their ingredients continued to flow out even heated for more than 10 hours. Therefore, it was considered that more delicious and healthier sauce could be made by adding jujubes when making beef leg bone brown sauce. Based on these results, even though brown sauce originated from western foods, it can be used to Koreans' taste by adding Korean ingredients. Moreover, more recipes can be made from the brown sauce added with jujube concentrate for more Asians including Koreans to enjoy.
Kimchi is a traditional Korean fermented vegetable food, the production of which involves brining of Korean cabbage, blending with various other ingredients (red pepper powder, garlic, ginger, salt-pickled seafood, etc.), and fermentation. Recently, kimchi has also become popular in the Western world because of its unique taste and beneficial properties such as antioxidant and antimutagenic activities, which are derived from the various raw materials and secondary metabolites of the fermentative microorganisms used during production. Despite these useful activities, analysis of the microbial community present in kimchi has received relatively little attention. The objective of this study was to evaluate the bacterial community structure from the raw materials, additives, and final kimchi product using the culture-independent method. Specifically, polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) was used to analyze the 16S rRNA partial sequences of the microflora. One primer set for bacteria, 341FGC-518R, reliably produced amplicons from kimchi and its raw materials, and these bands were clearly separated on a 35-65% denaturing gradient gel. Overall, 117 16S rRNA fragments were identified by PCR-DGGE analysis. Pediococcus pentosaceus, Leuconostoc citreum, Leuconostoc gelidum, and Leuconostoc mesenteroides were the dominant bacteria in kimchi. The other strains identified were Tetragenococcus, Pseudomonas, Weissella, and uncultured bacterium. Comprehensive analysis of these microorganisms could provide a more detailed understanding of the biologically active components of kimchi and help improve its quality. PCR-DGGE analysis can be successfully applied to a fermented food to detect unculturable or other species.
Pysicochemical and sensory characteristics of health concerned funtional cookies using various levels of crude ingredients of resistant starch were investigated in this study. The 10% substituted group had significantly higher pH values compared to those of control. Spread factor of control group had significantly the largest value and the 30% substituted group had the lowest values(p<0.05). Results of sensory characteristics showed significantly higher hardness, crispness and yellowness with 20% substituted sample group at p<0.05. Acceptance test of cookies with 10% substituted sample groups showed higher savory taste, texture, and overall acceptability and they did not show significant differences with the 20% substituted groups.
This study analyzed Kimchi eating culture in 178 households with female middle school children located in Incheon and Seosan areas, investigated the Kimchi eating patterns of female middle school students, and also analyzed the differences in value recognition for Kimchi between mothers and their female middle school students. Results showed that 23.0% of subject households answered eat Kimchi at every meal and the main reason for eating Kimchi in most households was good for taste. Most households made their own Kimchi, and only 12.3% of households bought Kimchi. Subject households preferred hot and spicy taste (34.8%) and pleasing taste (20.2%), and 44.4% of middle school children answered as eating Kimchi at every meal, and the source for information on Kimchi was home in 51.6% and mass media in 33.7%, suggesting the lack of school education. Both mothers and their female middle school students placed high value on Kimchi for its nutritional aspect and on Kimchi from the market for its convenience. Mothers showed significantly higher value (p<0.05) on the storage aspect of Kimchi compared to their middle school students, and female middle school students showed significantly higher value (p<0.05) on the value recognition for Kimchi as an international food compared to their mothers. Also, the value for hot pepper powder was high among other additional ingredients, and both mothers and middle school students had high values for Kimchi stew among other food dishes using Kimchi, and middle school students showed higher values (p<0.001) on foreign dishes using Kimchi such as Kimchi pizza and Kimchi spaghetti compared to the mothers group. Therefore, based on these results, the development of educational programs on Kimchi is needed not only at home but also at schools, by re-emphasizing the importance of value recognition for Klmchi in our food culture.

The purpose of this study was to analyze factors affecting acceptance of four kinds of dak-jjim samples in third year school-aged children (n=100). Soy sauce, red pepper paste, Vietnam fish sauce, and star anise were applied to samples for their familiar and exotic characteristics. Significant differences among samples were observed in odor, taste, and acceptance (p<0.001). Soy (Soy sauce sample), RPPaste (Red pepper paste sample), and Soy_FishS (Soy sauce and Vietnam fish sauce sample) samples scored higher than Soy_StarA (Soy sauce and star anise sample) sample. On the other hand, there were no significant differences in intensities of saltiness, sweetness, and hot spicy flavor (p>0.05). Liked attributes in samples were saltiness, sweetness, chicken flavor, potato flavor, moistness of chicken, hot spicy flavor, and color. Disliked attributes in samples were hot spicy flavor, saltiness, and ginger flavor. Significant differences among samples were observed in familiar intensity and willing to try again (p<0.001). Soy, RPPaste, and Soy_FishS samples scored higher than Soy_StarA sample. Panels considered taste (46%) and nutrition (45%). Higher familiar intensity of sample was associated with higher acceptance in samples. In other words, familiarity of food affects acceptance of food. Therefore, familiar ingredients such as soy sauce and chicken can be used for development of Korean menu items considering taste and nutrition with enhanced Korean food acceptance in school-aged children.
We attempted to develop a seafood menu by applying the most preferred recipes to the most disliked seafood menus in order to improve elementary schoolers' seafood menu preferences and consumption levels. A survey was conducted on the attitudes of 106 fifth graders about nine cooking methods and 37 school seafood menus served in the past 2 years. The deep-frying method was the most preferred by both boys and girls. The next preferred methods by boys were grilling and batter-frying while those by girls were stir-frying and batter-frying. The most disliked menus were cold jellyfish salad, mussel soup, dried-pollack soup, and sea-snail salad in that order. Mussel soup, dried-pollack soup, and seasnails salad ranked as the least preferred menu as well. Finally, standardized recipes for mussel croquette, dried-pollack Gangjeong, and batter-fried seasnails were developed. Consumption ratios of mussel croquette (85.94%), dried-pollack Gangjeong (79.55%), and batter-fried seasnails (75.5%) were significantly improved compared to the original menu (p<0.001). For mussel croquette, satisfaction scores for serving size, appearance, flavor, texture, and taste were significantly higher, and intakes of protein, phosphorus, iron, potassium, vitamin A, vitamin B1, vitamin B2, niacin, and vitamin C were significantly improved, as compared with mussel soup (p<0.001). Dried-pollack Gangjeong, texture and taste scores were significantly improved compared to dried-pollack soup. For batter-fried seasnails, protein, phosphorus, and iron intake levels and taste score were significantly improved compared to seasnail salad. Findings of the study suggest that a combination of disliked seafood ingredients and preferred recipes may be helpful in improving elementary school foodservice by increasing menu preference and consumption ratio.
This study aimed to identify the factors contributing to perceived healthiness by analyzing consumer reviews of healthy restaurants. While previous studies have primarily focused on the healthiness of food products, comprehensive research from the perspective of restaurants through online review analysis is limited. To achieve this, co-occurrence network analysis and LDA topic modeling, methods of text mining, were used to investigate consumers' health-related perceptions and preferences for healthy restaurants based on a large dataset of online reviews. The analysis revealed that consumers emphasize various health-related factors such as taste, ingredient categories, freshness, price, nutritional content, healthy options, and menu diversity when choosing healthy restaurants. These factors significantly influence the evaluation and selection of restaurants. Notably, it was found that the taste of food offered in healthy restaurants is closely linked to the perception of healthiness, highlighting the importance of a healthy taste derived from ingredients. In conclusion, this study provides practical insights into how healthy restaurants can reflect and meet consumers' health perceptions and suggests strategic directions for the food and dining industry to respond to health trends.
In this study, frying mix was prepared containing 0.5, 1.0, 1.5 or 2.0% brown rice fiber(BRF). The samples along with a control were then compared regarding their quality characteristics, including pasting properties, spreadability, pick-up ratio, color, textural characteristics, moisture and oil contents, and sensory qualities, all to determine the optimal ratio of BRF. For the pasting properties of frying mix, the control group was evidenced by a significantly higher peak viscosity, through viscosity, and final viscosity than that observed in the BRF samples. Breakdown was the highest at the 1.0% addition level, and time to peak viscosity and pasting temperature were maximal with the 0.5% addition. There was no significant difference in setback among the experiments. Spreadability and pick-up ratio of frying batter were not significantly different among the samples. As the BRF content increased, the lightness, greenness decreased, whereas yellowness increased. The BRF samples presented significantly higher hardness of fried batter than the control group and there was no significant difference in crispiness among the samples. Moisture content of fried sweet potato decreased with increasing BRF and oil content was the maximum on the control group. In the sensory evaluation, appearance, color, flavor, savory taste, yellowishness, coating thickness, off-flavor, and oiliness were not significantly different among the fried sweet potato samples. Bindingness, crispiness, and chewiness were highest in the control samples but minimal at a addition level of 2.0%. The control group evidenced significantly higher overall acceptability than were observed in the BRF samples. In conclusion, the results demonstrated that 0.5~1.0% BRF may prove quite useful as a additive for frying mix in the preparation of fried sweet potato and may provide favorable textural and functional properties.
This study was conducted to standardize the proper ingredient ratios of chinese cabbage kimchi by the sensory evaluation, chemical properties, and functional properties of antimutagenic effect and inhibitory effect on the growth of cancer cells from the ratios obtained from literatures. The standardized ratios of ingredient from the literatures was 13.0 of radish, 2.0 of green onion, 3.5 of red pepper powder, 1.4 of garlic, 0.6 of ginger, 2.2 of anchovy juice, 1.0 of sugar and the final salt concentration 2.7 in the proportion of 100 salted chinese cabbage. The standardized ratio of the ingredients exhibited better overall acceptability and less moldy smell and moldy flavor than any other ratio of ingredient in the sensory evaluation. The standardized kimchi with the above ratios of the ingredients, at final salt concentration of 2.5%, showed high reducing sugar contents and Leuconostoc sp. counts. All juices of the chinese cabbage kimchi showed not only high antimutagenicity against aflatoxin $B_1$ in Salmonella typhimurium TA100 but also strong inhibitory effect on the growth of AGS human gastric adenocarcinoma cells in SRB assay, especially these functional properties were the most effective at each standardized ratio of the ingredients. From the taste, chemical and functional properties, the standardized ratios of ingredients was 13.0 radish, 2.0 green onion, 3.5 red pepper powder, 1.4 garlic, 0.6 ginger. 2.2 anchovy juice, 1.0 sugar and the final salt concentration 2.5 in the proportion of 100 salted chinese cabbage.
