  • Physiological activity and antioxidative activity of Maesangi(Capsosiphon fulvescens) extracts with distilled water or 95% ethanol were investigated. For the evaluation of physiological and antioxidative activities, some evaluation assay methods such as measurement of Hunter color value, chlorophyll a/b value, total phenolics, reducing power and thiobarbituric acid(TBA) value of soybean oil were used. Proximate composition and mineral contents of Masaengi were orders of crude protein>crude fiber>moisture>crude ash>crude lipid, and K>Ca>Mg>Na>P>Fe>Zn, respectively. In ethanol extract, the content of total phenolic compounds in Maesangi was determined to half times of that in Dasima(Laminaria). The reducing power of Maesangi-ehtanol extract was about 5 % of vitamin C and was lower than that of Dasima-ethanol extract. The TBA value of Maesangi-ethanol extract on soybean oil oxidation was about 47 % and 68.4 % to control in three and eight days oxidation, respectively. But TBA value difference was not observed significantly with the dosage below 5mL of ethanol extract.

Chemical analysis showed that loquat fruit powder contained of 12.87% water, 2.23% crude protein, 0.55% crude fat, 3.57% crude ash and 3.89% crude fiber. Water content of Seolgidduk containing loquat fruit ranged from 36.58~39.18%. With more loquat fruit powder L value decreased, while the 'a' value and 'b' values increased. According to scanning electronic microscopy, Seolgidduk containing frozen-dried loquat fruit powder showed weak coherence. Hardness decreased with more frozen-dried loquat fruit powder. In the sensory test, Seolgidduk with 4% loquat fruit powder was the most preferred with less sourness, proper softness, moisture and chewiness. Based on the results of this experiment, Seolgidduk with 4% loquat fruit powder showed less hardness than the control group. These results show that quality and preference increased when 4% loquat fruit powder was added to Seolgidduk. Therefore, Seolgidduk with 4% of loquat fruit powder is expected to increase quality and preference of Seolgidduk.

  • In this work, the natural indigo production process from Polygonum tinctorium was balanced based on the traditional Niram method in Korea. A standard procedure was determined considering the conditions of indican extraction from plant material, the amount of alkali for precipitation, storage of extract, etc. The effect of experimental conditions on the yield of crude dye was investigated. The contents of indigo and indirubin of the crude dyes were analyzed by HPLC. Increase of the amount of crude dye was observed within 1-2.5 days of extraction time. Longer extraction beyond 2.5 days resulted in a slight decrease in the amount of crude dye. There was no consistency in terms of indigo content depending on extraction pH. We found that the storage of extract or harvested plants affected adversely to dye yield and dye quality. Based on the lab scale extraction, large scale extraction was performed for 2-2.5 days in water and 2.0-2.5 g/L of $Ca(OH)_2$ was applied for precipitation of indigo dye. We obtained natural indigo dye containing about 15% of pure indigo in scale-up production using whole plant except root.
