  • This study was conducted to investigate the quality of white pan breads as affected by various concentration of Cordyceps powder. Breads were prepared by addition of 0, 1, 2 and 3% of Cordyceps to flour of basic formulation. The moisture content of white pan breads decreased with increasing Cordyceps powder concentration. The pH of white pan breads also decreased with increasing Cordyceps powder concentration. In color values, with increase of Cordyceps powder concentration, L value decreased and a value increased in the crumb. The weights of breads cooled decreased with increasing Cordyceps powder concentration. The volume and height of dough decreased with increasing Cordyceps powder concentration. However, the specific volume and yield of dough were not significantly different among groups. The baking loss rate was higher in the breads with Cordyceps powder than in the control. In the texture characteristics, hardness and chewiness of breads significantly increased with increasing Cordyceps powder concentration and adhesiveness increased. In the sensory evaluation, when compared to the control, the breads added to 1% of Cordyceps powder was superior to in color and flavor, while was similar to texture and taste.

  • 일반 상법으로 제조되는 코오지, 즉 밀 또는 대두에 A. oryzae만으로 제조하는 코오지에 Cordyceps sp.를 첨가하여 코오지의 품질에 미치는 영향을 조사하였다. A. oryzae만으로 제조하는 코오지에 Cordyceps sp.를 일정량 혼합 첨가하여 제국하여 생균수 및 포자수를 측정한 결과 48시간까지 급격히 증가했다. 이후 생균수 및 곰팡이의 포자수의 유의할만한 변화를 볼 수 없어 제국시간을 48시간 전후로 조정하는 것이 바람직한 것으로 나타났다. 또한 amylase 및 protease등의 효소역가를 측정한 결과 Cordyceps sp.를 첨가한 코오지가 Cordyceps sp.를 첨가하지 않은 코오지보다 효소역가가 높은 것으로 나타났다. 제국이 끝난 코오지에 대하여 맛, 향 및 색깔에 대하여 관능검사를 실시한 결과 A. oryzae와 Cordyceps sp.를 각각 0.5%(w/w)를 혼합 참가한 것이 더 좋게 나타났다.

  • 동충하초 포자 현탁액을 누에에 경피 접종하고 발병경과를 관찰하여 누에의 형태적 변화와 균사체 형성 번데기의 형태 및 성분변화를 조사하였다. 누에 유충 때 발병 치사된 누에는 불완전세대를 거쳐 분생포자를 형성하고 번데기 때 병사한 번데기는 균사체를 형성하고 자낭포자를 생산하는 완전 세대의 동충하초가 되었다. 발병하지 않은 건강한 번데기와 균사체 형성 번데기의 성분변화는 유리아미노산, 구성아미노산, 지방산, 핵산물질, 모두 차이가 있었다.

  • This study was carried out to develop an optimum baking formula and baking process for a new bread raw material with added Cordyceps militaris powder, which has been known to prevent various adult diseases and cancers. The rheological properities of dough made from Cordyceps militaris powder-wheat flour with 0, 1, 2, and 3% Cordyceps militaris powder added-were investigated. A farinogram showed that the water absorption and weakness value of dough increased with added Cordyceps militaris powder, but development time and dough stability were decreased. An extensogram showed that resistance to extension was increased in bread with 1% Cordyceps militaris powder, but decreased in bread with 2% and, 3% powder. Extensibility decreased fermentation progressed. An amylogram showed that gelatinization point was increased but maximum viscosity was decreased with added Cordyceps militaris powder. With increased amounts of powder dough volume during fermentation was reduced. The change in pH values of dough after mixing, fermentation, and proofing decreased with increased amounts of added powder.

  • Cordyceps, one of the most valued traditional Chinese medicines, consists of the dried fungus Cordyceps sinensis growing on the larva of caterpillar. It is also known as 'winter-worm and summer-grass' because of its appearance during different seasons. The parasitic complex of the fungus and the caterpillar is found in soil of a prairie at an elevation of 3,500 to 5,000 meters in northwestern part of China. According to Chinese medicinal theory, Cordyceps is used to replenish the kidney and soothe the lung, and indeed many clinical applications have been reported. The natural Cordyceps is rare and expensive on the local market, and therefore, several mycelial strains have been isolated from natural Cordyceps and manufactured in large quantities by fermentation technology, and they are commonly sold as health food products in Orient. The adulterants of Cordyceps are commonly found on the market, and therefore the authentication of these products has to be defined. Having the urgent need from current market, different chemical markers such as nucleoside, ergosterol, mannitol and polysaccharide are being used for quality control of Cordyceps. Unfortunately, these markers are far from optimization, and therefore extensive works are needed to define the pharmacological efficiency of these markers.

  • The earliest pre-Linnaean fungal genera are briefly discussed here with special emphasis on the nomenclatural connection with the genus Cordyceps Fr. Since its valid publication under the basidiomycetous genus Clavaria Vaill. ex L. (Clavaria militaris L. Sp. Pl. 2:1182, 1753), the genus Cordyceps has undergone nomenclatural changes in the post-Linnaean era, but has stood firmly for approximately 200 years. Synonyms of Cordyceps were collected from different literature sources and analyzed based on the species they represent. True synonyms of Cordyceps Fr. were defined as genera that represented species of Cordyceps Fr. emend. G. H. Sung, J. M. Sung, Hywel-Jones & Spatafora. The most common synonyms of Cordyceps observed were Clavaria and Sphaeria Hall, reported in the 18th and in the first half of the 19th century, respectively. Cordyceps, the oldest genus in the Cordyceps s. s. clade of Cordycipitaceae, is the most preferred name under the "One Fungus = One Name" principle on priority bases.

  • Flavor characteristics of raw Cordyceps militaris significatntly different from those of dried one. In the case of raw Cordyceps militaris , major flavor components were composed of 5 alcohols, 3 ketones, 4 phenols, 9 alkanes , and 3 alkenes. The major alcohol was 1-octen-3-ol(22.56%, 1147.3% ng/ml), which contributed to the characteristic green flavor. Ketones (3-ocatone, inparticular )were present in the highest concentration in raw Cordyceps militaris . In contrast, major flavor components of dried Cordyceps militaris were composed of 4 alcohols, 4 ketones, 3 furans, 4 pyrizines, 2 dithiazines, 5 phenols , 8alkenes , 17 alkanes, and 8 fatty acids. Dried Cordyceps militaris had unique sweet aroma of sesame as wella s a milky flavor. Green or fruit flavor were rarely detected . In alkanes , 10 cosanes, component fo wax were present. Typical flavor components of alkanes such as $\beta$-caryophyllen and Δ-cadinene were also detected. Fatty acids of dried Cordyceps militaris ranged from myristic acid (14 :0) to linoleic acid (18 ; 2). The sweet aroma of dried Cordyceps militaris was mostly due to pryazines, dithaiazines, and furans. Two dithaizines were identified and characteristics of these flavor components was a roasted bacon flavor. Strong antibacterial acitivity was observed toward Vibrio spp. such as V. vulnificus, V.cholerae, V. parahaemlyticus. Relatively high antibacterial acitivity was shown toward Bacillus subtilis , B,cereus, Staphyllococcus aureus, and Corynebacterium xerosis.
