  • The dextransucrase activity of microorganisms which were identified as contributing to the fermentation of jeungpyeon made with yeast was measured. The dextran generated during fermentation was quantified and the viscosity changes were measured. The mechanism of network structure formation was clarified by observing the inside of the network structure over the fermentation periods ranging from 1 to 7 hr using scanning electron microscopy (SEM). The pH of jeungpyeon batter decreased significantly as the fermentation proceeded, whereas the viscosity increased. The identified lactic acid bacteria (LAB) were Leuconostoc mesenteroides subsp. mesenteroides, Pediococcus pentosaceus, Tetragenococcus halophilus, and Leuconostoc mesenteroides subsp. dextranicum. The yeast was identified as Saccharomyces cerevisiae A/Tor. Pretorien. The dextransucrase extracted from those microorganisms showed high activity. On the other hand, the amount of dextran generated from the batter increased significantly beyond 2 hr of fermentation, and the viscosity increment showed a similar trend. The SEM photos showed that the most homogeneous fine network structure was observed in the batter fermented for 2 hr. Therefore, we assumed that the dextran that was generated by microorganisms during fermentation interacted with the components of the batter to increase the stability of the network structure.

  • This study sought to develop a healthier type of jeungpyeon, or Korean rice cake, by adding Korean black raspberry powder (Rubus coreanus). The moisture content, color, volume, symmetry, uniformity, texture, and sensory quality characteristics were evaluated in order to determine the optimal amount of raspberry powder to add to rice flour in order to get the best-tasting, healthiest food. We substituted 0.5%, 1.0%, 1.5% and 2.0% of rice flour with Rubus coreanus powder and mixed 3%, 6%, 9% and 12% Rubus coreanus concentrate with water to make dough. The result was stored for up to 48 hours at $20^{\circ}C$, and then evaluated. Jeungpyun with Rubus coreanus powder and Rubus coreanus concentrate had the right flavor, color, fermentation, and taste, compared to the other groups. Consequently, in overall acceptability, the highly rated Rubus coreanus powder-PW(1.5%) and Rubus coreanus concentrate - BA (6%) will be the most desirable.

  • This is a comparative study of Byung-Kwa-Ryu (Korean rice cake and cookie) of the Chungcheon Province Area in the late Joseon Dynasty, based on 「Jusiksiui」 in the late 1800s, 「Eumsikbangmunnira」 in 1891, and 「Banchandeungsok」 in 1913. This study was also compared with the recipes of 「Suunjapbang」 of 1540, 「Eumsikdimibang」 of around 1670, 「Siuijeonseo」, and Gyuhabchongseo of the late 1800s. As for the Byung-Kwa-Ryu(Korean rice cake and cookie) introduced in the recipe book, 「Eumsikbangmunnira」 recorded the most with 18 types of rice cakes and two types of Korean sweets, followed by 「Jusiksiui. There were 14 types of rice cakes, and two types of Korean sweets. 「Banchandeungsok」 had eight types ofrice cakes and six types of Korean sweets. Yogi-tteok in 「Jusiksiui」 and 「Banchandeungsok」 were foods that could not be found in other recipes. Yakgwa and Jeungpyeon were in all three books as well as 「Eumsikdimibang」. These were also included in 「Siuijeonseo」 and were introduced to most cookbooks. The materials used and the method of making it differed for each recipe. Many studies on cookbooks have focused on the Yeongnam region so far. This study served as an opportunity to confirm the dietary life data of the Chungcheong-do region through a review of the recipe books containing food from the Chungcheong-do region. In addition, it was possible to examine the ingredients and cooking methods used in each cookbook at the time through comparative analysis with the cookbooks in the Yeongnam region.

  • This study was conducted to investigate traditional Kyunggi area Korean foods suitable for standardization and commercialization as well as to investigate the perceptions of experts about these foods, and to analyze the important value factor characteristics according to classified traditional food groups by residents of the Kyunggi(n=104)areas of Korea. We determined the degree of value of various traditional foods by asking respondents to 13 items based on a 5 point Likert scale, and used the total scores of the items to determine their value. Based on the results of the total scores and frequently chosen foods, we attempted to select the foods suitable for standardization and commercialization. The results are summarized as follows. For main dishes Ogok-bap was selected as the primary suitable for standardization and commercialization. Next were Incheon yeong yang bap, Hobak-beombek, Hobak-juk, Gesungpyeonsu, Tteokguk, Kimchibap, Kimchimandu, and bap, respectively. Of the side dishes Bossam-kimchi was selected as the primary suitable food for standardization and commercialization followed by Bindaetteok, Sondubu, Samgyetang, Baekkimchi, Doenjang-jjigae, Suwongalbi, Japchae, and Cheonggukjang-jjigae, respectively. Finally, for favorite foods, Duteop-tteok was selected as the primary food suitable for standardization and commercialization. Next were Jeungpyeon, Yakgwa, Yaksik, Maejakgwa, Ssuk-tteok, Yeongeunjeonggwa, Songpyeon, and Osaekdasik, respectively. This study shows that a resident's evaluation of a traditional Kyunggi Korean food is affected by the their sense of value of the food, as well as by the social structure, which includes the population, economic condition, food policies, industrial technology, and culture. This research was conducted to preserve traditional Kyunggi Korean foods and to improve this area's regional income from the prospect of sellable goods. We expect that this research to be used as basic data in the development of new commercial traditional foods by the food industry, by offering a better understanding of diverse consumer sense and to also be used with dietary education data relative to following traditional meal patterns for diverse age groups.
