  • Screening of anticoagulant activity was conducted for the hot water extracts of 73 kinds of medicinal herbs, 41 kinds of Korean edible plants, and 5 kinds of sea weeds using plasma recalcification test(Tr). In the first screening several extracts of the plants, Alisma calndiculatum, Corydalis ternata Panax notoginseng, Allium sativum, Ganderma luidum, Codium fragile, showed high activities. When the plants were reextracted with various solvent conditions, acidic water extracts of Codium fragile showed the highest activity in APTT. A crude polysaccharide fraction(CF-1) was prepared by methanol reflux, ethanol precipitation, dialysis and Iyophilization of the acid extracts. CF-1 comprised 80.8% total sugar consisting of arabinose, galactose and glucose as the main monomers, 8.7% protein, and 13.3% sulfate. The anticoagulant activity of CF-1 was not changed by pronase digestion, but decreased by periodate oxidation, and this indicated that the anticoagulant activity was attributed to the polysaccharide portion.

  • In order to manufacture the alcoholic drinks using cultured wild ginseng roots(CWGR) of 5 and $10\%$ (w/v), sugar content of fermentation media was adjusted to 24-25 $^{\circ}$Brix with white sugar and glucose. And 3 kinds of yeast (S. cerevisiae(KCCM 50757), S. cerevisiae (KCCM 50583) and S. bayanus(ATCC 10601) were used and then the quality of alcoholic drinks was analyzed by physical, chemical and sensory evaluation. Alcohol content was highest value of $15.8\%$ in $10\%$ of CWGR, white sugar, and S. bayanus(ATCC 10601). Major alcohols were ethanol and 1-propanol. Number of yeast cells increased to 5 days fermentation and slightly decreased afterwards. The pH was decreased abruptly from 5.0 in initial fermentation to 3.1-4.1 in 5 days fermentation. Total sugar contents were decreased continuously with fermentation periods and showed 7.0-10.5 $^{\circ}$Brix in 20 days fermentation. Saponin patterns and contents were various and higher in wine treated with S. bayanus(ATCC 10601). From the sensory evaluation, the highest score of overall quality was observed in the alcoholic beverage of $10\%$(w/v) of CWGR, glucose, and S. cerevisiae(KCCM 50583).

  • In order to develop fermented silkworm "Dongchunghacho" (Paecilomyces tenuipes) with improved absorption and increased effectiveness, we fermented Dongchunghacho using four kinds of microorganisms, viz., lactic acid bacteria, Bacillus subtilis, Natto bacillus, and yeast. A total of 15 samples were fermented using a combination of microbial inoculation culture and conditions to produce fermentation products. The contents of basic components such as sugar, reducing sugar, protein, total polyphenol, and total flavonoid were examined as well as the antioxidant, tyrosinase inhibitory, and thrombolytic activities of the fermented products were analyzed. We observed that reducing sugar and protein contents decreased in most of the fermented products, but the products fermented using yeast exhibited higher sugar content and, thus, higher sweetness. Total polyphenol content and antioxidant activity did not increase in fermented products compared to non-fermented Dongchunghachos, but total flavonoid content and tyrosinase inhibitory and thrombolytic activities increased by fermentation. In particular, total flavonoid content and tyrosinase inhibitory and thrombolytic activities primarily increased in the products fermented using yeast and lactic acid bacteria. However, it was not possible to confirm the increase in these activities in samples fermented by single fermentation using only yeast. Therefore, we propose that it will be possible to develop fermented food from silkworm Dongchunghacho (P. tenuipes) with excellent health benefits through additional study of multiple fermentation conditions using lactic acid bacteria and yeast.

  • In this study, 20 kinds of raspberries and blackberries, cultivated or wild in Korea, were collected. Weight, moisture content, sugar content, sugar composition, pH, titratable acidity and acid composition of the fruits were determined. Weight of each of the fruits and moisture contents in the fruits were $0.9{\sim}7.8g$ and $26{\sim}62%$, respectively. The sugar contents in the fruit juices were $6.9{\sim}16.9%$ (Brix). The major sugars in the fruits were glucose ($40.7{\sim}84.0%$ (w/w) of the total sugars) and fructose ($6.5{\sim}57.5%$). Sucrose and xylose were also detected in a small quantity. pH and titratable acidity of the berry juices were $2.8{\sim}3.9%$ (w/v, citric acid) and $0.6{\sim}2.9%$, respectively. The major organic acids were citric acid ($14.6{\sim}87.5%$ (w/w) of the total acids) and malic acid ($9.6{\sim}87.1%$). Succinic, tartaric and oxalic acids were also detected in a small amount.

  • Three kinds of foods (strawberry jam, J; braised lotus root, B-LR; stir-fried anchovies, SF-A) containing fructooligosaccharide (FOS) or isomaltooligosaccharide (IMO) were prepared, and the changes of physical properties and sugar composition were compared with control (sample containing sucrose). For the samples contaning oligosaccharides, $a^*$ value increased, and $b^*$ value decreased after cooking. The sample with sucrose showed higher hardness than those with FOS or IMO. For sugar composition and stability of the oligosaccharides after cooking, the amount of IMO was almost remained in each food, however, that of FOS decreased from 47.2, 49.5, 48.9 to 20.5, 49.0 and 28.8%, for J, B-LR and SF-A, respectively. Based on the above results, softer cooked food could be prepared with oligosaccharide than sucrose, and when considering to functionalitiy, IMO is more suitable for general cooking at home than FOS.
