  • The quality characteristics and antioxidative activity of garlic pickles prepared with persimmon vinegar with or without Maesil (Japanese apricot) juice were investigated. Heat treated garlic cloves ($110^{\circ}C$, 5 min and then rapidly cooling) were salted with NaCl and $CaCl_2$, and then soaked in pickling solution, and stored at $20^{\circ}C$. The pH of the garlic pickles initially ranged from 2.36~3.24, after which the pH slightly increased to 3.22~4.13 during storage, while the acidity was decreased to 1~1.97. Throughout the entire storage periods, the acidity of the garlic pickle containing persimmon vinegar and Maesil was the highest (1.97%). The hardness of the control sample (non heated garlic) decreased during storage, whereas the hardness of all the heat treated groups did not change after 21 days of storage. Moreover, the chewiness of the persimmon vinegar+Maesil group was the highest among the groups. The Hunter color L value of garlic pickles decreased during storage, while the b value (yellowness) increased for all groups except the two persimmon groups. The $IC_{50}$ of the DPPH radical scavanging activity of garlic pickles at 5 day of storage was 85.98~97.81 mg/mL. However, the antioxidative activity of garlic pickles gradually increased with longer storage times. The persimmon vinegar+Maesil group showed the highest antioxidative activity. Results from the sensory evaluation showed that scores of flavor, taste and over-all preference were higher for the persimmon vinegar+Maesil group than the other groups (p<0.05).

  • The purpose of this study was to estimate the antimicrobial activity of Maesil (Japanese apricot, Prunus mume) extract against Vibrio vulnificus. The strains tested in the study were 28 V. vulnificus isolates originated from fish, seawater, mud flat and seawater in fish restaurant. The vvhA gene was detected using real-time PCR and biochemical identification expressed above good identification in 28 isolates of V. vulnificus. All of V. vulnificus used in this study was susceptible to tetracycline and chloramphenicol antibiotics. These two antibiotics were considered to be useful for the treatment of patients. Maesil extracts 2.5% and 5% showed antimicrobial activity against V. cholerae NCCP 13589 and V. parahemolyticus NCCP 11143. V. vulnificus isolate and V. vulnificus NCCP 11135 showed growth inhibition at 1.25%, 2.5% and 5% of Maesil extract, respectively. Compared with V. cholerae and V. parahemolyticus, the antibacterial activity of Maesil extract against V. vulnificus was high. The minimum bactericidal concentration of Maesil extract for V. vulnificus was 1.6%. These results revealed that Maesil extract was found to be very useful for inhibiting the growth of V. vulnificus and can be expected to prevent food poisoning caused by V. vulnificus.

Estimation of Daily per Capita Intake of Total Phenolics, Total Flavonoids, and Antioxidant Capacities from Commercial Products of Japanese Apricot (Prunus mume) in the Korean Diet, Based on the Korea National Health and Nutrition Examination Survey in 2010 (2010년 국민건강영양조사에 근거한 매실가공품 섭취로부터 한국인의 일인당 하루 총페놀, 총플라보노이드 및 항산화능 섭취량 추정)

  • The total phenolics, total flavonoids, and antioxidant capacities of ten commercial products of Japanese apricot (maesil) were evaluated, including four kinds of alcoholic drinks, two kinds of soft drinks, and four kinds of concentrate found in the Korean market. The daily per capita consumption (g/capita/day) of each product was calculated from in the existing dataset of the Korea National Health and Nutrition Examination Survey in 2010. Using the combined datasets indicated above, the daily per capita intake of total phenolics from maesil product consumption was found to be 1.05 mg gallic acid equivalents. The daily per capita intake of total flavonoids was determined to be 0.13 mg catechin equivalents, and the daily per capita intake of antioxidant capacities were measured at 0.70 mg vitamin C equivalents (1,1-diphenyl-2-picrylhydrazyl assay), and at 1.04 mg vitamin C equivalents (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) assay). The daily per capita intakes of total phenolics, total flavonoids, and antioxidant capacities were influenced by the daily quantity of consumption of maesil products, as well as their compositional contents.

  • Recently, IoT technology has been applied in various field. In particular, the technology focuses on analysing large amount of data that has been gathered from the environmental sensors, to provide valuable information. This technique has been actively researched in the agro-industrial sector. Many researches are underway in the monitoring and control for growth crop environment in agro-industrial. Normally, the average weather data is provided by the manual agro-control method but the value may differ due to the different region's weather and environment that may cause problem in the disease and insect-pest prevention. In order to develop a suitable integrated system for fruit tree, all the necessary information is obtained from the Jeollanam-do province, which has the high production rate in the Korea. In this paper, we propose an integrated support platform for the growing crops, to minimize the damage caused due to the weather disaster through image analysis, forecasting models, by using the micro-climate weather information collection and CCTV. The fruit tree damage caused by the weather disaster are controlled by utilizing various IoT technology by maintaining the growth environment, which helps in the disease and insect-pest prevention and also helps farmers to improve the expected production.
