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.

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.

This study was performed to observe the effects of the feeding physiological activity substance in Cordyceps militaris hot-water extract intake on the improvement of lipid components and metabolic enzyme activities in the serum of dietary hyperlipidemic rats (SD strain, male) fed the experimental diets for 5 weeks. The concentrations of cholesterol (total cholesterol, ${\beta}$-lipoprotein, LDL-cholesterol, free cholesterol and cholesteryl ester), atherosclerotic index, triglyceride (TG), phospholipid (PL) and blood glucose in sera were remarkably lower in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. In the ratio of HDL-cholesterol concentration was higher percentage in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. The activities aminotransferase (AST, ALT) in sera were rather lower in the Cordyceps militaris extract administration than in the hyperlipidemic rats. From the above research, Cordyceps militaris extract were effective on the improvement of the lipid compositions in sera of dietary hyperlipidemic rats.

The effect of light on production of cordycepin (3'-deoxyadenosine) was investigated using Cordyceps militaris. Among Cordyceps spp. tested, C. militaris KCTC 6064 was the best for cordycepin production, After 120-hr cultivation of C. militaris KCTC 6064 at $24^{\circ}C$ in YMG broth with light (1,000 lux), 51.6 mg/l of cordycepin was produced. In general, production of cordycepin with light illumination was better than that without light. Cordycepin production under light illumination was enhanced up 96-hr cultivation, whereas after 96-hr, cordycepin production was decreased.

Cordyceps militaris has shown to have various pharmacological activities including an immune-modulatory effect. Previously, we reported that anti-influenza effect of C. militaris in DBA/2 mice was mediated by increased IL-12 and the activation of NK cells. In this study, we investigated the effect of C. militaris on adaptive immune responses using DBA2 mice immunized with influenza vaccine. To determine the effect of C. militaris on antigen presentation capability, we treated RAW 264.7 cells with various concentrations of ethanol extract of C. militaris, which showed a significant upregulation of CD86 (B7.2), CD284 (TLR4), CD40, H-2k (MHC I) and I-Ad (MHC II). To examine the direct effect of C. militaris on adaptive immune responses, we immunized DBA2 mice with influenza vaccine in presence or absence of C. militaris. After 2 or 4 weeks, influenza-specific T cell proliferation, HAI titers and IFN-${\gamma}$ production were measured in plasma or PBMCs isolated from animals. Influenza-specific T cell proliferation and HAI titers were not considerably increased in immunized mice in presence of C. militaris. However, the production of IFN-${\gamma}$ was much greater in immunized mice with C. militaris as adjuvant than only immunized mice.

Hepatic fibrosis refers to the scarring of liver tissue, often resulting from chronic liver injury or inflammation. It is characterized by excessive deposition of extracellular matrix proteins, impairing liver function and potentially progressing to cirrhosis if left untreated. To improve the liver functions, Cordyceps militaris, a species of parasitic fungus known for its medicinal properties, is used in the form of extract. It has been traditionally used in Chinese medicine to boost energy, improve stamina, and support overall health. In this study, we investigated the hepatoprotective effects of Cordyceps militaris extract powder in a liver injury model induced by hepatic fibrosis. Sprague-Dawley (SD) rats were administered Dimethylnitrosamine (DMN) to induce liver injury, and the hepatoprotective effects of Cordyceps militaris extract powder intake were assessed by comparing changes in liver enzyme levels and histological observations. Rats injected with DMN were orally administered Cordyceps militaris extract powder at doses of 0, 125, 250, and 500 mg·kg^-1·day^-1 for three weeks. After three weeks of treatment, no significant differences were observed in hematological, clinical chemical, organ weight, gross examination, or microscopic examination between the DMN-alone group and the Cordyceps militaris extract powder-treated group. In conclusion, hepatoprotective effects against DMN-induced liver injury in SD rats treated with Cordyceps militaris extract powder were not observed under this study condition.

The quality characteristics of breads with different concentrations(2%, 4%) of Paecilomyces japonica (J2, J4) and Cordyceps militaris (M2, M4) powder were compared in terms if sensory and mechanical properties. In the sensory test, J2 and M2 groups gained good scores in taste, texture and odor acceptance as control grourp. Paecilomyces japonica-added group showed higher moisture and bigger volume than that of control group, and Cordyceps militaris group showed lower moisture content and decreasing volume. 'L' values of J and M groups was lower than control, and the longer the storage period, the lower the lightness. The more Paecilomyces japonica was added, the higher the 'a' value was, but Cordyceps militaris showed an opposite trend. The hardness of the bread was the lowest in J2 group and the highest in M4 group, and the longer tile storage period. the higher the hardness was (p＜.001). Overall, the addition of 2% Paecilomyces japonica showed a similar tendency with control group, and showed good scores especially in acceptance, moisture and volume. Paecilomyces japonica appeared to be more desirable than Cordyceps militaris.

The objective of this study was to investigate the effects of the feeding Cordyceps militaris extract on the improvement of the free fatty acid, lipid peroxide, creatinine and enzyme (creatine phosphokinase; CPK, lactate dehydrogenase; LDH, alkaline phosphatase; ALP, lecithin cholesterol acyltransferase; LCAT) activities in the sera of dietary hypercholesterolemic rats (SD strain, male) fed the experimental diets for 5 weeks. Concentrations of free fatty acid, lipid peroxide and CPK, LDH, ALP activities in sera were fairly reduced in the Cordyceps militaris extract administration group (CHE) than in the hypercholesterolemic diet group (CHD). However, no significance was found in the effect of an creatinine concentration among the groups. The LCAT activity in serum was increased in the Cordyceps militaris extract administration (CHE) than in the hypercholesterolemic diet group (CHD). From these results, Cordyceps militaris extracts were effective on the improvement of the lipid components and metabolic enzyme activities in sera of dietary hypercholesterolemic rats.
