  • This study was conducted to develop functional sprout vegetables with antioxidant effects using seeds of Arctium lappa. The seeds germinated vigorously under light at $25^{\circ}C$, reaching germination rate of 82% within 4 days. Germinated seeds were placed under darkness at various temperatures to force growth in length, and it was demonatrated that $20^{\circ}C$ was optimum temperature. Greening treatment reduced growth in length, but promoted growth of cotyledons. Harvested A. lappa sprout vegetables maintained freshness longer at $10^{\circ}C$, rather than $4^{\circ}C$. Ventilation holes in storage containers had no effects on storage periods. Antioxidant activity of vegetable that received greening treatment for 1-3 days was investigated, and it was shown that free radical scavenging effects and ferrous ion chelating effects was higher than those of commercially available brocoli, cauliflower, pea and bean sprout. Contents of total polyphenol and flavonoid were also higher, especially by 3 day greening. The longer the treatment, the more the inhibition on peroxidation of linoleic acid. Sprout vegetable of A. lappa had higher antioxidant activity compared with adult plant. In conclusion, sprout vegetable of A. lappa has great potentiality for use as one of sprout vegetables.

  • This study was done to examine antioxidant compounds, antioxidative activity and chemical properties in organically cultivated sorghum seed and their sprout, and to examine as a basic data for various application methods as an organic farming product of sorghum. The crude protein and mineral contents in the sprout had 2.5 and 1.6~9.87 folds more than sorghum seed, respectively. Total polyphenol content as antioxidant was more in the sprout showing $4,135mg\;GAE\;g^{-1}$ than the seed, whereas total flavonoid content was relatively higher in the seed showing $3.86mg\;GAE\;g^{-1}$. ABTS radical scavenging activity in the seed was observed by higher level as $15.78mg\;TE\;g^{-1}$. However, The sprouts with and without natural light were no significant difference. DPPH radical scavenging activity in the seed exhibited activity of 11 folds or more compared to that of the sprout. The highest activity was detected from the seeds and the sprouts in Donganmae. Although sorghum was no significant correlations among the varieties, it showed correlation with between the light-treated condition and antioxidation.

  • This study evaluated the baby-leaf growth, leaf red color intensity, and phytochemical compounds, such as total phenols and total flavonoids using domestic Amaranthus accessions, to select promising germplasm for the use of baby-leaf vegetable. The 39 accessions, upper 15% of 262 Amaranthus germplasm collection showing high red color intensity in baby-leaf, measured as Hunter's a value, were primarily selected. The eleven accessions including IT199970, showing stable red color intensity in baby-leaf both in high-temperature and low temperature cultivation, were finally selected as promising germplasm for the use of baby-leaf vegetable Amaranthus. The leaf red color intensities when they were cultivated at low temperature period were generally higher than those at low temperature period, and all the eleven selected germplasm, including four Amaranthus sub-species and five unknown species, showed stable red color expression in baby-leaf. The total phenol and total flavonoid contents were also presented for finally selected germplasm including their baby-leaf fresh weights. These finally selected germplasm could be potentially used as baby-leaf vegetable resources, through fortifying the color balance of salad vegetable.

  • This study was conducted to find out the effect of vitamin C treatments on the storability of several baby vegetables; endive, green romaine lettuce, pak-choi, red romaine, lollo rosa, and ssamchoo. The vitamin C was treated by the foliar spray which was carried out 3 times before harvest or dipping in vitamin C solution for 5 minutes after harvest. The vitamin C contents of 6 different baby vegetables were higher in vitamin C treatments than control, whereas the difference of vitamin C content between treatments was disappeared after storage. The fresh weight of ssamchoo and lollo rosa lettuce treated by vitamin C was maintained higher than that of control. There was not significant difference in visual quality among treatments, though some of baby vegetables treated by washing with vitamin C showed better visual quality than the others. The contents of carbon dioxide, oxygen and ethylene in MAP with baby vegetables did not show any difference among treatments. As the result, high concentrated vitamin C treatment, such as the foliar spray and washing (dipping) had a role of increasing functionality, but the enhanced functionality, high vitamin C, did not affect storability in baby vegetables.
