  • Objectives: The importance of kimchi as a traditional food in Korean cuisine has gradually decreased due to rapid industrialization, economic growth and changes in dietary patterns in Korea. This study aimed to examine the shifts in kimchi consumption by region and by income level between 2005 and 2015 in Korea. Methods: Data from the Korea National Health and Nutrition Examination Surveys III (2005) and VI (2015) were used in the study (n=15,558). Intake of kimchi was estimated using a single 24-hour dietary recall. The sample weights were applied in all analyses to reflect population estimates. All statistical analyses were carried out by using SPSS IBM Statistics 20. Results: Kimchi intake has significantly decreased by 27.6 g/day per capita during the last decade in Korea; 25.0 g for males and 29.9 g for females, respectively. Over the past decade, the decline of kimchi intake has been particularly significant in Seoul, Busan, Incheon, Gyeonggi, and Gwangju, while there has been no significant change in males living in rural areas. The consumption of kimchi across all income levels has decreased, however, the decrease was higher in 'middle and low income level'. The amount of kimchi consumption in 2015 was the highest in 'low income level'. The results were similar after adjusting for gender and age. Conclusions: For the past decade, the overall intake of kimchi in Korea has decreased, however, it has been found that the decrease of kimchi intake for males living in the rural areas was not significant. Therefore, in order to keep our traditional kimchi culture and promote a balanced diet including kimchi for Korean, it is necessary to develop more efficient policies and approaches. A variety of dishes using kimchi should be developed, besides merely serving kimchi with rice as a side dish, to increase the consumption of kimchi.

  • The purpose of this study was to determine the optimum condition for producing tea leaf Jeung-pyun that does not contain added parched tea leafs (0, 0.5, 1, 1.5, and 2%) while producing Jeung-pyun that has a variety of functional ingredients and to investigate the possibility of making practical application of tea leafs. Moisture contents were 56 ~66% and there were no significant differences among the samples. The pH of Jeung-pyun samples was 5.65~5.74. The L-value decreased as the amount of added tea leaf increased, and the a-value was low in the group made with added tea leafs. The b-value was high in the 1% added group and had a tendency to increase vs the control group as amount of added tea leaf increased. In the groups with added tea leaf the volume was evaluated as being higher in the order of 1>1.5>2%. The specific volume of the group with added tea leaf was evaluated as being higher in the order of 1>1.5>2%. Sensory characteristics of the group with added tea leaf were evaluated as being high. For characteristics of cell uniformity, rice wine flavor, and sweetness, the control group was evaluated as being high, and for characteristics of color, moistness, and softness the 1% added group was evaluated as high. Astringency was evaluated as being high in the 2% added group. Texture profile analysis was conducted after samples were maintained in an incubator at $20^{\circ}C$ for 0, 1, 3, 5, and 7 days. Characteristics for hardness, gumminess, chewiness tended to increase with longer periods of storage. Characteristics for cohesiveness, springiness tended to decrease as the storage period increased. As determined by this study, addition of 1% tea leaf was the most favorable method for making use of tea leafs the production of Jeung-pyun and a potentiality for the use of tea leafs in food was discorvered.

  • This study delves into the general characteristics of spirits brewed in the Central Region of Korea-Seoul, Kyonnggi-do, Chungchung-do-paying particular attention to their varieties and fermenting methods and also comparing similarities and differences of their features. It is found first of all that there are a wide range of variety in the kinds of liquors. Among the 21 spirits investigated, not a single one resembles any one of the remaining in terms of the raw material, and the brewing method and process. Secondly, all of them use locally produced grains and can be classifiable as belonging to the common category of yakju (clean spirit) with fragrant elements added for the purpose of enhancing health or decreasing any harmful effects after drink. Thirdly, these traditional folk wines are characterized by the addition of secondarily fermented spirits. The more secondarily fermented spirit a wine has, the more fragrant and palatable it becomes and also the less harmful. Fourthly, all the spirits of this region are fermented by using yeast kodupap (steamed rice). The brewing temperature is usually around $15{\sim}20^{\circ}C$ for $5{\sim}8$ days or $3{\sim}4$ days for the majority of the cases. Fifthly, purifying is done with the yongsoo (strainer), the sieve, traditional Korean paper, etc. As such, we can say that all the brewers endeavor to maintain Korean traditional methods of wine making.
