  • From the point of breeding view for our future, 20 Korean varieties of red pepper for the contents of capsaicinoids, free amino acids, free fatty acids and organic acids with powder product and eating qualities were chosen, and the sensory properties of their water and ethanol extract were compared in order to investigate the influence of the composition of test components on sensory acceptability of Korean red pepper. The composition of taste components in red pepper powder varied wildly depending on the varieties; total capsaicinoids content variety from 0.029 to $0.913\%$, free sugar 8.45 to $20.2\%$, and organic acid 4.58 to $19.54\%$. Capsaicinoid contents especially dihydrocapsaicin content, were highly correlated with pungent taste of the methanol extract of red pepper power, but did not show significant relationship to the overall sensory acceptability. However, the components analyzed here and eating and processing qualities include high variations and future breeding sources.

  • This paper provides a comprehensive description of previous studies of making and developing kimchi in terms of the origins of kimchi and the changes in the history of kimchi, along with newly discovered data, including the collection of works in Joseon Dynasty as well as old cookbooks discovered after the year 2000, and latest research in related disciplines, e.g., ancient history studies, archeology, and linguistics. Because new ruins and relics, such as the Liao-ho Civilization in the Northeast Asia continent, which was closely related to Dongyi tribes, have been discovered and studied, it is important to determine how to reflect the outcome of archeological studies on the origin of preserved vegetables. In addition, to describe the background and changes in the independent formation of making Korean kimchi chronologically, they were divided into the following: development from jjanji to singunji; formation of the basis for seokbakji dressed with fermented fish sauce; settlement of seokbakji culture for dressing seokbakji with fermented fish sauce and spices, including chili varieties when they were introduced; and establishment of the method for making whole cabbage kimchi, which is currently typical kimchi made by adding the seokbakji as the stuffing of the cabbage kimchi, to examine the time and specific details of the change.

  • This study investigated the main dishes of menus at university faculty cafeterias to understand current lunch menu trends. A sample of 1040 menus was collected from Internet homepages of 52 universities between March and May, 2014. The main dishes of menus were categorized into six groups based on main ingredients and cooking methods. The most frequently served main dish ingredient was pork followed by fish/seafood, and poultry. Pork dishes and chicken dishes were mainly roasted, pan fried, or deep fried with various carbohydrate ingredients to bulk them up. Large amounts of chili pepper, corn syrup, and oil were added to improve the bland flavor of these dishes, which contain starchy ingredients. In contrast to pork dishes or chicken dishes, 40.2% of beef dishes was served in a more traditional way as soup. Fewer kinds of fish or seafood were used, and the cooking methods also lacked diversity. In conclusion, main dish menus at university faculty cafeterias have undergone changes in terms of ingredients and cooking methods. Meat dishes cooked using traditional methods are becoming less common, especially for pork and chicken dishes, which are quite sweet, salty, and spicy. Extensive use of carbohydrate ingredients was found in some meat dishes and side dishes in one-dish meals.

  • This study analyzed the effect of the intrinsic and extrinsic attributes of gochujang, Korean red chili paste, on purchasing intention and recommendation intention for consumption. Survey participants were female, married, aged 30 - 39 years, and highly educated with graduation from a university. Most participants purchased gochujang 1 - 2 times per year, most commonly at a shopping mall, and acquired information on the gochujang product from an advertisement or sponsored TV shows. For the factor analysis, five variables for intrinsic quality were considered: namely, healthiness, economics, convenience, diversity, and sense, whereas three variables were considered for extrinsic quality: trust, external appearance, and image. The factor analysis also confirmed the correlation between the validity and the reliability of the purchasing and recommendation intentions. The effect of intrinsic quality of gochujang on purchasing and recommendation intentions was tested through a multiple regression analysis. The purchase intention was most significantly affected by healthiness, cost, and convenience. On the other hand, the recommendation intention was most significantly affected by the diversity and, to a lesser degree, by the healthiness of the product. Among the extrinsic qualities, trust of consumers and the product appearance had a significant effect on purchasing intention. Recommendation intention was significantly affected by the appearance. And trust significantly influenced the recommendation. Therefore, a concrete and systematic marketing approach considering these factors.

A Study on the Kimchi Recipe in the Early Joseon Dynasty through 「Juchochimjeobang」 (「주초침저방(酒醋沈菹方)」에 수록된 조선 전기(前期) 김치 제법 연구 - 현전 최초 젓갈김치 기록 내용과 가치를 중심으로 -)

  • This study aims to examine the contents of "Juchochimjeobang", a cookbook about Jeotgal kimchi, and review its value in the history. This cookbook was published between about 1500s and early 1600s, and its book title is unknown because both the front and the back covers thereof are missing. However, the cookbook contains many wine and kimchi recipes, accounting for 66%, and "Juchochimjeobang" was thus named after the recipes. "Juchochimjeobang" has 126 recipes in 120 categories, and this study examines 20 kimchi recipes and 7 recipes for preserving vegetables. "Juchochimjeobang" has a specific recipe for making Jahajeot and Baekajeot kimchi which are described in literature published between 1400s and 1500s. Although the recipes for making the aforementioned two types of Jeotgal kimchi are simple because jeotgal is just mixed with main materials, they are different from the recipe for Seokbakji described in Gyuhapchongseo, a cookbook written in the 19th-century Joseon Dynasty. Seokbakji described in Gyuhapchongseo is made by mixing spices of ginger, spring onion, chili powder with other materials. This implies changes of making Seokbakji over time. Moreover, "Juchochimjeobang" is a very valuable historical cookbook because it has unique recipes, for example, adding sesame liquid, chinese pepper, willow and the like.

  • Bacillus subtilis BS16045 was isolated from Gochujang, a Korean red chili paste, in order to get a starter strain that can be used for preservation of the fermented foods. We report the whole genome sequence of B. subtilis BS16045, which contains 4,165,121 bp with a G+C content of 43.6%. We also confirmed the set of antibiotic genes producing surfactin, kanosamine, bacillaene, plipastatin, subtilosin A, and bacilysin, which are related to antifungal and antibacterial activities. These results indicate that B. subtilis BS16045 could be a potential starter strain for solving contamination by food-borne pathogens in the soybean products factory.

  • Fungal diseases including anthracnose, stem rot, blight, wilting, and root rot of crops are caused by phytopathogens such as Colletotrichum species, Sclerotinia sclerotiorum, Phytophthora species, and Fusarium oxysporum and F. solani which threaten the production of chili pepper. In this study, to identify biological control agents (BCAs) of phytopathogenic fungi, potentially useful Bacillus species were isolated from the field soils. We screened out five Bacillus strains with antagonistic capacity that are efficiently inhibiting the growth of phytopathogenic fungi. Bacillus species were characterized by the production of extracellular enzymes, siderophores, and indole-3-acetic acid (IAA). Furthermore, the influence of bacterial strains on the plant growth promoting activity and seedling vigor index were assessed using Brassica juncea as a model plant. Inoculation with Bacillus subtilis SRCM 121379 significantly increased the length of B. juncea shoots and roots by 45.6% and 52.0%, respectively. Among the bacterial isolates, Bacillus subtilis SRCM 121379 showed the superior enzyme activities, antagonistic capacity and plant growth promoting effects. Based on the experimental results, Bacillus subtilis SRCM 121379 (GenBank accession no. NR027552) was finally selected as a BCA candidate.

  • This study aimed to provide an accurate estimate of sodium intake from jangajji by examining the changes in sodium content according to the type of jangajji and the length of storage period, specifically differentiating between the solid ingredients and the seasoning liquid. It focused on six types of jangajji: chili pepper, perilla leaf, onion, radish, garlic scape, and cucumber. The sodium content in the solid ingredients and the seasoning was measured using a salinometer and ICP-AES. The results indicated that across all types of jangajji, the seasoning liquid consistently contained significantly higher levels of sodium than the solid ingredients. When comparing the sodium content measured by ICP-AES with that from a salinometer, the salinometer readings were significantly lower for both the solid ingredients and the seasoning liquid in all types of jangajji. Additionally, when comparing the sodium content of the solid ingredients with that listed in the nation's representative nutritional databases, a substantial discrepancy was noted, with some cases potentially overstating the actual sodium intake from jangajji. Overall, this study suggests that an urgent review should be conducted to identify and resolve the causes of such discrepancies and accurately estimate the actual sodium intake from jangajji.

  • A bacterial strain MPL-01 was isolated from the large intestine of a wild boar. The strain was shown to have morphological, physiological and biochemical characteristics, fatty acids composition typical of Bacillus. The 16S rRNA gene sequence showed that the isolate formed distinct phyletic line that was most closely related to this of Bacillus atrophaeus (99.99%). It was proposed that the strain is classified as B. atrophaeus MPL-01. The strain MPL-01 exhibited the strongest antifungal activity against Colletotrichum acutatum, the pathogen of anthracnose of chili peppers. The ethyl acetate extract of culture filtrate possessed not only the antifungal activity but also the bio-surfactant activity. Therefore, the strain MPL-01 could be a useful bacterium in the development of bio-control process against the pathogenic fungi.
