  • Deonjang has been developed as a fermented food in Korea. It produces a distinctive flavors and tastes during the fermentation process. The purpose of this study was to determine the quality characteristics of commercial deonjang certified for traditional foods. We investigated the amino nitrogen, sodium chloride(NaCl), total colony counts, coliforms, Bacillus cereus and isoflavone of 24 commercial deonjang samples certified for traditioinal foods. Deonjang showed wide ranges in amino nitrogen(105.76~318.93 mg%) and NaCl(12.53~16.51%). Survey distribution of microflora investigation in the total colony counts were detected in all 24 samples(100%), and the range is low $1.5{\times}10^6$ CFU/g, at the highest $2.5{\times}10^9$ CFU/g respectively. For the coliform, the following results were $0{\sim}5.0{\times}10^1$ CFU/g. B.cereus was detected in a total of four samples were $2.5{\times}10^3{\sim}3.3{\times}10^4$ CFU/g in the distribution. Daidzein of isoflavones showed the lowest at 86.7 ppm, 681.8 ppm range of the best shows and genistein as low as 0 to 50.0 ppm respectively. This research provided information for quality characteristics of commercial deonjang certified for traditional foods.

  • Japan launched its regulatory certification system for organic foods based on the amended JAS laws in June 2000, followed by the implementation of regulations on organic agricultural products and organic processed foods in January 2001 and with the implementation of the standards on organic animal husbandry and organic feed by the Ministry of Agriculture, Forestry & Fisheries in 2005, organic foods have been under integrated and systematic supervision. Certification of organic foods can be undertaken by registered accredited bodies (private certification bodies) or legal entities conforming to the regulations of the Ministry of Agriculture, Forestry & Fisheries. However, with the amendment of the JAS laws in March 2006, only legal entities conforming to the regulations of the ISO/IEC GUIDE 65 are eligible as certification bodies. Foreign organic products imported to Japan must be certified organic under JAS regulations and must be manufactured or produced by foreign manufacturers certified by local or foreign registered accredited organizations and distributed with the Organic JAS Mark affixed or through importers certified by local registered accredited organizations and distributed with the Organic JAS Mark affixed on the products. It can be implied from the Japanese case study that it necessary to reform the diverse agricultural products certification systems to set up an integrated certification system, and the restructuring of government organizations, reforms of environmentally-friendly agricultural products certification system and the integration of the organic food certification systems are needed in order to integrate the control of the standards and certification systems.

  • This study was performed to examine the levels of biogenic amines (BAs) in foods of animal origin such as egg, ham, sausage, milk, cheese and yoghurt distributed on Korean domestic markets, and to compare the results with those of western countries. Egg yolk had more BAs than egg white. BAs detected in ham samples were the highest level in barbecued tender loin ham. Sausage samples had less BAs than ham samples. However, the delicatessen sausages had significantly higher levels of histamine than the other sausage samples (p<0.001). Cadaverine, spermidine and spermine were detected in market milks and their concentrations were very low compared with other samples. In Cheddar cheese, tyramine (44.46${\pm}$0.83 ${\mu}$g/g) was the major BA. The major BA of stirred yoghurt samples was histamine. These results suggest that BAs of the foods of animal origin distributed on Korean domestic markets were not much different from those of western countries and would not cause any harmful effect to consumers.

  • This study analyzed trends and contents of ancestral ritual foods of Korean traditional Jong-ga as a domestic thesis. In searching the keywords related to ancestral ritual foods using a thesis search site, a total of 15 theses in seven journals were selected for analysis. Three theses from 1996 to 1999, six theses from 2005 to 2008, and another six theses from 2012 to 2016 were announced. In measuring frequency by dividing case families analyzed in the thesis into region, there were 83 families, including seven families from Gyeonggi (8.4%), seven families from Chungcheong (8.4%), two families from Honam (2.4%), and 67 families from Yeongnam (80.8%). Fifty-four families out of 67 families from Yeongnam were located in Andong-si, occupying 65.1% of the 83 families. The family showing the highest frequency was 'Seoae Jong-ga' (12 times). The family clan with the highest frequency was eight families of the 'Jinseong Lee clan' In the future, it would be necessary to understand the research flow through analysis of research trends in ancestral ritual foods of Jong-ga as well as interdisciplinary research and methodological diversification of studies on ancestral ritual foods of Jong-ga.

  • The trend towards forming economic blocs coupled with global economic arrangements such as DDA and FTA increase pressure on the liberalization of the agricultural sector. South Korea is taking part in the DDA negotiations. Once the DDA negotiations are implemented, the extent of liberation of the agricultural market is expected to be wider and timing of market opening is sooner than those effects of the UR agricultural agreement. A reduction in tariff rates and the government subsidy will follow, accordingly. However, many analysts in the agricultural sector express deep concern over a negative development in local agricultural market as demonstrated in China where the local market was dominated by imported agricultural products. This study aimed to investigate progress that China made in favor of the agricultural industry, including environment-friendly agricultural policy, and suggest ideas to drive the development of the agricultural industry in a better direction in Korea by comparing the two countries.

  • This study was conducted to investigate the quality characteristics of peach jelly following the addition of various gelling agents (locust bean gum, carrageenan, xanthan gum). The various gelling agents were added to peach jelly at five levels (1.0, 1.5, 2.0, 2.5 and 3.0%), after which their effects on physicochemical properties, textural properties and sensory qualities were investigated. The total titratable acidity (TTA) of peach jelly was decreased with increases in gelling agent. Additionally, the sweetness and pH of peach jelly increased significantly as the amount of various gelling agents increased. Moreover, the lightness (L-value), redness (a-value) and yellowness (b-value) of peach jelly was decreased as the amount of gelling agent. Furthermore, the hardness, gumminess and chewiness of the peach jelly increased as the amount of gelling agent increased. Finally, the overall acceptance was higher for jelly containing 2.0% added gelling agent than for other samples. Based on the results of this study, it is recommended that mixed gelling agents be added to peach jelly at 2.0%.

  • This study examined the nutrient components and measured the physicochemical properties of 23 Korean sweet potato cultivars. The proximate composition, free sugars, organic acids, and dietary fiber of sweet potato were analyzed and the water binding capacity, oil absorption and pasting characteristics were measured. The proximate composition was the highest in Happymi and was higher in colored sweet potato than in general sweet potato (p<0.05). The sucrose content was the highest among the free sugars in the general cultivars and yellow/orange colored cultivar. The major organic acids were oxalic acid, citric acid, malic acid, succinic acid, fumaric acid, and acetic acid. Oxalic acid and citric acid were high in the purple colored cultivars and malic acid was high in yellow/orange colored cultivars. Each total dietary fiber content of the general and colored cultivars was 7.51-13.94 and 13.04-16.97%, respectively, but there was no significant difference. The water binding capacity and oil absorption of Juhwangmi was high in all cultivars (p<0.05). The peak viscosity of sweet potato powder showed highest a significant difference of 12.50-1342 cP (p<0.05). The breakdown of Sincheonmi was 512, which was the highest value (p<0.05). The setback of Geonpungmi was significantly low, 6.0 (p<0.05).

  • This study was conducted to investigate which food items are perceived as HANSIK (Korean food) in Korea. 562 males and females aged 20-70 were surveyed on 512 most frequently consumed dish items from 4th Korean National Health and Nutrition Survey if they perceive it as HANSIK. Dish items in kimchi, namul sukchae (cooked and seasoned vegetable) and jeotgal (salt-fermented food) category showed high response rate to be perceived as HANSIK. The response rate of twigim (frying foods) as HANSIK was low showing less than 70%. The response rate as HANSIK for foreign origin foods such as ramen and jjajangmyeon (black bean paste noodle) were lower than 25%. In jang yangnyum (seasoning) category, doenjang (soybean paste) and gochujang (red pepper paste) showed high response rate as HANSIK more than 90%. Females showed a higher response rate as HANSIK than males for most food items except several items of myen mandu (noodle and dumpling). The younger age group had higher HANSIK perception on many items of recently consumed foods, especially budae-jjigae (spicy sausage stew) (p < 0.001) and jwipo-jorim (braised dried filefish) (p < 0.001), implying that they already accept the common foods as HANSIK regardless of the origin. These results provide an information on the foods perceived as HANSIK among currently consumed common foods in Korea and these results can be utilized for establishment of HANSIK concept reflecting transition of dietary life in Korea.
