  • This study was designed to evaluate the quality characteristics and antioxidant activities of noodles containing Allium senescens L. powder (0, 2, 4, 6, and 8%). With an increase in the consumption of Allium senescens L., there was a decrease in pH (p<0.001), water absorption ratio, volume expansion ratio, and turbidity (p<0.05). The colorvalue showed that the addition of Allium senescens L. decreased the L and b values. On the other hand, a value was increased (p<0.001). The mechanical texture of the noodles containing Allium senescens L. was decreased by the addition of Allium senescens L. considering its hardness and chewiness; however, it increased the adhesiveness, springiness, and cohesiveness (p<0.001). In the sensory evaluation, the noodles with 4% Allium senescens L. powder showed the best results (p<0.001). The total polyphenol content, total flavonoid content, DPPH radical scavenging, and reducing power were increased upon addition of Allium senescens L. powder (p<0.001).

  • This study evaluated the antioxidant and anti-inflammatory activity of ethanol extracts using three parts of the chives plant: the bulb, the leaf, and the flower. As a result of DPPH and ABTS radical scavenging ability, the scavenging activity of the flower extract was higher than that of the bulb and leaf. In addition, as a result of FRAP analysis, antioxidant activity increased in all extracts depending on the extract concentration. The total polyphenol content was high in the following order: flower (11.29±0.37 mgGAE/g) > leaf (6.61±0.14 mgGAE/g) > bulb (5.7±0.67 mgGAE/g) extract. The cytotoxicity of the three extracts against rat macrophage RAW264.7 cells and HaCaT cells, both of which are human cutaneous keratinocyte cell lines, was minimal. NO by LPS was generated as a result of examining the anti-inflammatory activity of each extract through the NO colorimetric analysis method and ELISA. TNF-α secretion was decreased to a significant level in the flower ethanol extract. Therefore, these results indicate that there is a high possibility that the ethanol extract of chives, a natural plant resource, can be used as a cosmetic raw material.

Effect of the extracts of various foods and medicinal herbs on the antioxidant activity and sensory characteristics of jujube-omija herbal sauce (식품과 한약재 에탄올 추출물이 대추.오미자 약선소스의 항산화 및 관능적 특성에 미치는 영향)

  • In order to increase the antioxidant effect and preference of jujube-omija herbal sauce, we added ethanol extracts of 12 kinds of food and 12 kinds of medicinal herb to the sauce, and then evaluated the antioxidant activity and sensory characteristics. The antioxidant activity of the jujube-omija herbal sauces was greatly increased by the addition of ethanol extracts of foods such as green tea, mugwort, mint, lemon, leek, etc. and those of medicinal herbs such as ginseng. pine needle, the root of arrowroot, orange peel, etc.. Due to the high content of phenolic compounds, the ethanol extracts foods and medicinal herbs appeared to be responsible for high electron-donating ability and low hydroperoxide productivity. While the jujube-omija sauce with the extracts of green tea, mugwort, ginseng and pine needle were not preferred by the panels due to bitter taste and aroma, those of lemon, fruit of Chinese quince, orange peel, etc. were preferred with their sweet and a little sour taste and showed a high antioxidant activity. Especially, lemon juice was the best to increase the antioxidant activity and the preference of the jujube-omija herbal sauce.

  • This study was conducted to select leaf vegetables suitable for cultivation in apartment verandas and simple and easy fertigation method for home gardening. In order to develop the convenient fertigation method, hydroponics, wick irrigation, and overhead irrigation methods were compared. For the wick irrigation, two types of nutrient sources were used; one was slow release fertilizers mixed with medium and the other one was nutrient solution filled in container located under pots. The growth of leafy lettuce, leaf mustard, and leaf beet was better in both of the wick irrigation methods rather than in overhead irrigation and hydroponics. The wick irrigation method is very easy, so that it is expected to bring a good result from the cultivating and managing point of view, if it brings with commercialized system along with slow release fertilizer. As a result of investigation of environment such as temperature, relative humidity, and irradiance level in apartment verandas in autumn the highest irradiance level during a day was just 48% and 35% in verandas facing south and feeing southeast, respectively, comparing to that in greenhouse. The light environment was investigated as a limiting factor for vegetable growing in verandas. Therefore, to select the vegetables showing good growth under low irradiance environment, nine leaf vegetables such as romaine lettuce, lent lettuce, head lettuce, endive, pak-choi, leaf mustard, garland chrysanthemum, leaf beet, and Chinese chive were grown under 0%, 50%, 70%, 90% shading. Among them, Chinese chive showed the best growth under low irradiance levels. Endive showed line growth reduction according to shading degree, however, even under 90% shading condition, it showed good growth. And then leafy lettuce, garland chrysanthemum, and pak-choi followed. Therefore, these results will be of help in selecting vegetables for veranda gardening with different light levels.
