  • The study was conducted to identify the anti-inflammatory and anti-cancer effects in sprouts of mouse-eyed bean (Rhynchosia nulubilis), ginseng (Panax ginseng), perilla (Perilla frutescens), broccoli (Brassica oleracea var. italica), and lettuce (Lactuca sativa) grown with organic germanium concentrate. Western blot analysis was performed to assess the anti-inflammatory activity of the extract. All extracts exhibited noticeable anti-oxidant activity, indicating a significant correlation between the germanium content and anti-oxidant activity (p<0.05). In particular, rat-eyed bean sprouts with the highest germanium content showed significant anti-inflammatory activity (p<0.05) by significantly inhibiting the expression of the inflammatory complexes, NLRP3, cytokines IL-1β and caspase-1. Ginseng and broccoli sprouts showed strong anti-cancer properties and had high anti-oxidant effects (p<0.001). Germanium-concentrated water allows the mass production of agricultural products containing high concentrations of organic germanium. Agricultural produce grown with germanium concentrate add organic germanium to various physiological active ingredients, increasing the anti-oxidant and anti-cancer effects. These results strongly suggest that agricultural products containing high germanium concentrations can be used as novel health supplements to improve health.

  • The physico-chemical properties of broccoli sprouts cultivated in a plant factory system with different lighting conditions were investigated. We reported that there were significant differences among the chemical and nutritional properties of the broccoli sprouts grown under different light sources. Two kinds of sugars (glucose and fructose) were detected in the plants. The amount of glucose was 2.94~3.12% and that of fructose was 1.54~2.04%. Total chlorophyll was $1,157{\pm}0.004$ mg% and chlorophyll-a $777{\pm}0.01$ mg%. All over the test materials, 2 kinds of organic acids (citric acid and malic acid) were detected. The level of citric acid was 908~1,136 mg% and its highest level was under the (Blue LED) light source. The level of malic acid was 514~834 mg% and its highest level was under the (Red LED) light source. Seven different minerals were also analyzed. The amount of K was 518 mg% and its amount was significantly higher than that of Mg or Na. There were also negligible amounts of Zn, Fe and Cu. The amounts of vitamin A, C and E under the Red LED were, $860.62{\pm}0.02\;{\mu}gRE$, $134.570{\pm}0.14$ mg% and $1.44{\pm}0.1$ IU. The amounts under the Blue LED were, $432.48{\pm}0.05\;{\mu}gRE$, $137.05{\pm}0.1$ mg% and $1.11{\pm}0.12$ IU. The amounts under both Red and Blue LEDs were, $667.33{\pm}0.11\;{\mu}gRE$, $118.50{\pm}0.09$ mg% and $1.47{\pm}0.1$ IU. And finally, the amounts under a White LED were, $640.25{\pm}0.08\;{\mu}gRE$, $119.87{\pm}0.07$ mg% and $1.31{\pm}0.15$ IU. In this study, significant changes were shown in the chemical and nutritional properties of the broccoli sprouts. These findings indicate that LED light sources stimulated germination of the plants.

  • Salmonellosis is an important worldwide foodborne infectious disease that is transmitted by many food vehicles including raw and processed animal products and fresh produce. In this study, the effectiveness of automated ELISA ($VIDAS^{(R)}$) and realtime PCR in the detection of Salmonella spp. in steamed pork and raw broccoli sprouts was evaluated by comparing their results with those of a conventional culture method. Bulk samples (500 g) of steamed pork and raw broccoli sprouts were inoculated with various levels of Salmonella and divided into 20 samples (25 g each). All the samples, including the controls, were analyzed using a conventional culture method, $VIDAS^{(R)}$, and real-time PCR to detect the presence of Salmonella. In addition, the levels of background flora in the steamed pork and the raw broccoli sprouts were determined. In the steamed pork that contained less than 100 CFU/g of aerobic bacteria, all three methods detected low levels of Salmonella without a statistical difference in their performance. In the broccoli sprouts with high quantities of background flora (ca. $6.7{\times}10^7$ CFU/g), however, all three methods were unable to detect low levels of Salmonella, and real-time PCR and $VIDAS^{(R)}$ more sensitively detected Salmonella than the culture method, with significant statistical differences. In conclusion, $VIDAS^{(R)}$ and real-time PCR could be superior to conventional culture methods in detecting Salmonella in food with high levels of background flora.

  • This study was conducted to compare the storability of some sprout vegetables; alfalfa, broccoli, radish, red-cabbage, and red-radish, packed with 50 low density polyethylene (LDPE) film in MA storage. Most of all 5 different sprout vegetable crops maintained the fresh weight higher than 99% until 10 days storage at 2 and $8^{\circ}C$. The carbon dioxide concentration in packages was higher at 8 than at $2^{\circ}C$. It was higher in radish and red-radish sprouts than other crops. As the oxygen concentration showed opposite trends to carbon dioxide, that of radish and red-radish sprouts decreased more than 3% after 3 days in 8 storage. Ethylene concentration in the packages of alfalfa was 0.1 ppm, significantly higher than other four crops with less than 1.0 ppm. Temperature treatment, however, did not influence the ethylene concentration in packages. The radish and red-radish sprouts, with lowest oxygen concentration in package, showed lowest off-flavor compared to the others. The visual quality of these sprouts in packages showed higher at $2^{\circ}C\;than\;at\;8^{\circ}C$ and was maintained the highest in radish sprouts, followed by red-radish, broccoli, red-cabbage, and alfalfa sprouts in that order. In conclusion, as the sprout vegetables have different shelf-life, of which radish was $4{\sim}5$ days longer than that of alfalfa the distributed condition of sprout vegetables should be differently controlled according to kinds of crops.

  • The effect of several factors on efficiency of anther culture of broccoli was studied. The medium supplemented with 14% sucrose, 125mg/L of silver nitrate and 0.1mg/L of each of NAA and 2,4-D was best in embryogenesis in all varieties tested. The effect of auxin was affected by silver nitrate, that is, it lowered embryogenesis when the concentration of NAA and 2,4-D was low, but it enhanced when their concentrations were high. Benzyl aminopurine increased embryogenesis in some varieties, but decreased in others. Although microspore embryogenesis was observed in anthers of which heigest was 1 to 0.6 - 1.0 of petal heigest in the bud, which corresponds to the early uninucleate to early binucleate stage of the microspores, it was much better when the ratio of heigest was 1 : 0.8. More embryos ware inducted from culture in March than in February in general. Because there was a big yearly variation, it was assumed that microspore embryogenesis was influenced greatly by the culture condition and the physiological condition of donor plants.

  • This study investigated the effects of image on the preference and intake frequency of 19 vegetables. A total of 359 usable surveys were collected using a convenient sampling method. The subjects included females (51.8%), university students (50.7%), home residents (66.9%) and subject's spending 20,000~40,000 won on meals/week (41.5%) and eat out 2~3 times/week (29.5%). The intake frequency of vegetables was 2~3 times per month. The healthy image of all vegetables was good overall and the average preference was 3.78 (out of 5 on the Likert). Tomatoes had the healthiest image, onions the highest preference, and Korean cabbage the highest intake frequency. For males, the vegetable with the healthiest image was sesame leaf, while the healthiest foods for females were broccoli and tomatoes. Elementary students had a healthier image of cucumber, bean sprouts, radish, sesame leaf, lettuce, radish leaf, and cabbage than university students and adults. Home residents had a healthier image of cabbage and burdock than other types of residents. Subject that st over 20,000 won per week on meals had a higher image of most vegetables. In terms of preference, males liked Korean cabbage, green pumpkin, balloon flower roots, radish leaf, and lotus root, but female liked tomatoes. In addition, elementary students, home residents, and subjects who eat out less often tended to prefer vegetables. In terms of intake, there was a high frequency of intake for all vegetables in adults. Home residents specifically had a higher intake of cucumber, carrot, bean sprouts, spinach, green pumpkin, balloon flower roots, lettuce, radish leaf, broccoli, burdock, lotus root, and tomato. Overall, the healthy image of vegetables had a positive influence on their preference and intake frequency. Therefore, to encourage the intake of vegetables, direct or indirect variables should be examined.
