  • This study investigated the functional nutrition of red yeast rice to added beurre mani$\acute{e}$ in the production of brown sauce. We added X to Y at levels of 0%, 5%, 10%, 15% and 20% and investigated the effects on the viscosity, water content, turbidity, pH, sugar level, reducing sugar, color, and sensory quality characteristics of the resultant brown sauce. The viscosity of Brown sauce was increased with increasing red yeast rice beurre mani$\acute{e}$ while water content and turbidity were decreased. pH was between 4.57~4.91. Sugar level and reducing sugar were increased with increasing red yeast rice powder content. L and a were increased with increasing red yeast rice powder content, and b was decreased. In sensory testing, visual appearance and flavor were highest for brown sauce preparations containing 15% and 20% X. Aftertaste and taste scored the highest for additions of 10% and 15%. For general preference, a 15% addition of X resulted in the highest score. Based on the results, it seems that red yeast rice powder, 15% red yeast rice powder added brown sauce has the highest the general preference.

  • This study was performed to evaluate the effect of red-yeast-rice on bone metabolism in overiectomized (OVX) rats. Forty female Sprague-Dawley rats (body weight 210 $\pm$ 5 g, 9 weeks old age) were divided into two groups. One group were OVX, and the other group received sham operation (SHAM), and received either control diet (20% casein) or a red-yeast-rice power supplemented diet (0.1%) for 9 weeks. And then each rat group was further divided into control diet (casein 20%) and red-yeast-rice powder supplemented (0.1%) diet group. All rats were fed on experimental diet and deionized water ad libitum for 9 weeks. Bone mineral density (BMD) and bone mineral content (BMC) were measured using PIXImus (GE Lunar Co, Wisconsin, USA) in spine and femur on 5, 9 weeks after feeding. The serum and urine concentrations of Ca and P were determined. Bone formation was measured by serum osteocalcin and alkaline phosphatase (ALP) concentrations. And bone resorption rate was measured by deoxypyridinoline (DPD) crosslinks immunoassay and corrected for creatinine. Serum osteocalcin, growth hormone, IGF-l and calcitonin were analyzed using radioimmunoassay kits. Urinary Ca and P excretion were not significantly different among the groups. Within the OVX group, the red-yeast-rice group had a lower crosslinks value than the casein group. Therefore the red-yeast-rice supplemented groups had a lower bone resorption ratio than the casein group in the ovariectomized rats. And, the red-yeast-rice group had significantly higher IGF-l hormone than casein group in ovariectomized rats. The red-yeast-rice group had higher spine bone mineral content than those of control group within the OVX groups. This study was an important first step in establishing that the observed beneficial effects of red-yeast-rice on bone, and this study also established the need for a study on the long-term effect of this supplement in a human.

  • The quality of emulsion-type sausage manufactured using various amounts of red yeast rice powder (0, 1, 2, 3%) was investigated. Moisture and ash content increased, whereas the protein content decreased, upon increasing the red yeast rice powder content. The pH, lightness, and yellowness values of the uncooked and cooked samples decreased upon increasing the red yeast rice powder content. The redness of the cooked and uncooked samples containing 3% red yeast rice powder was higher than those of others. Cooking loss and emulsion stability of samples decreased upon increasing red yeast rice powder contents. Samples containing 2 and 3% red yeast rice powder showed lower viscosity than others. Sensory evaluation of samples increased with increas in red yeast rice powder content. Thus, red yeast rice powder improved the physicochemical and sensory properties of emulsion-type sausage.

  • This study focused on alcohol fermentation properties of red ginseng extracts using Saccharomyces cerevisiae JF-Y3. Central composite design was employed to investigate the influence of red ginseng extract content ($10{\sim}50%$, v/v) and yeast extract ($0.5{\sim}2.5%$, w/v) on the properties of alcohol fermentation added with red ginseng extracts. Yeast cell growth was affected both by red ginseng extract content and yeast extract content, and red ginseng extract content had a greater effect on yeast cell number than yeast extract content. Yeast cell number increased along with decrease of the red ginseng extract content and with increase of yeast extract content. Alcohol content was maximal at 30% red ginseng extracts and 0.50% yeast extract and the predicted maximum value of alcohol content was 12.45%. Brix degree and total sugar content were significant within 1% level (p<0.01), and brix degree was affected both by red ginseng extract and yeast extract content. Total sugar content was significantly affected by red ginseng content.

  • Red yeast rice flour, which is a natural functional material, was used in muffin production at different concentrations ranging from 0 to 10%. The initial pasting temperature was not affected by the addition of red yeast rice flour, whereas peak viscosity and final viscosity decreased with increasing concentrations. The lightness value of the muffins decreased, however, the redness value increased with increasing amounts of red yeast rice flour. The bulk of the muffins was generally reduced by the addition of red yeast rice flour. At the 10% concentration, hardness and viscosity were similar to the control, and there were no changes in springiness or cohesiveness. For the sensory evaluation, parameters such as appearance, color, texture, taste, and overall acceptability increased significantly from the control at the 3% concentration of red yeast rice flour, but flavor decreased with increasing amounts of red yeast rice flour. Based on these results and the sensory evaluation specifically, the optimal amount of red yeast rice flour added to the muffins was the 3% concentration.

  • This study was performed to evaluate the effect of red-yeast-rice on blood lipids and also to investigated the relation of blood lipids, bone related hormones, and bone mineral density in overiectomized rats. Forty female rats (body weight $210\pm5$g) were divided into two groups. The rats in the first group were ovariectomized which the others received sham operation (SHAM). And then each rat group was further divided into control diet $(casein\;20\%)$ and red-yeast-rice powder supplemented $(0.1\%)$ diet group. All rats were fed on experimental diet and deionized water ad libitum for 9 weeks. Bone mineral density (BMD) and bone mineral content (BMC) were measured using PIXImus in spine and femur. Bone formation and bone resorption were measured by serum osteocalcin and urinary deoxypyridinoline (DPD) crosslinks value. Serum growth hormone, IGF-1 and calcitonin were analyzed using radioimmunoassay kits. The red-yeast-rice group had significantly lower the blood triglyceride concentration and had lower the blood total cholesterol concentration than casein group did in ovariectomized rats. And the red-yeast-rice group than casein group in ovariectomized rats. The red-yeast-rice group had significantly lower the atherogenic index than control group within the ovariectomized groups. In the experimental rats, serum total cholesterol concentration was negatively correlated with femur BMC and crosslink value. Crosslink value was negatively correlated with spine BMC and IGF-1. Osteocalcin concentration was negatively correlated with crosslink value. Growth hormone was negatively correlated with crosslink value and positively correlated with spine BMC. The findings of this study suggest that red-yeast-rices are beneficial for blood lipid in ovariectomized rats. And when considering a population-based public health approach to lowering cholesterol and bone loss, and preventing coronary heart disease and osteoporosis, the red-yeast-rice dietary supplement could provide a new approach for the maintenance of healthier cholesterol and bone.

  • This study demonstrates that red yeast rice exhibits radical scavenging and antihypercholesterolemic activities in rats fed cholesterol. Sprague-Dawley male rats were divided to five dietary groups (normal, chol-control; and M-1, M-2 & M-3 administered 150, 300, and 500 mg/kg red yeast rice, respectively) and fed their respective diets for 4 weeks. No significant differences in food efficiency ratio (FER) were found among the five groups. The weight of perirenal fat pads decreased with increasing amounts of red yeast rice supplementation. There was a significant decrease in the levels of cholesterol in M-3 group fed red yeast rice with 500 mg/kg compared to those in the chol-control, M-1 and M-2 groups (p<0.05). Among the rats fed the cholesterol-enriched diet, all groups fed red yeast rice showed higher concentration of the HDL cholesterol, but lower concentration of the LDL cholesterol than those of the chol-control group. The scavenging activity of the methanol extract from red yeast rice was increased with increasing amounts of the extract. The glutathione content in the normal group and in the M-3 group were higher than that in the other groups. The M-3 group showed similar hepatic glutathione contents to those of the normal group. These results suggest that red yeast rice may be safe and effective for lowering serum levels of total and LDL-cholesterol, ratio of non-HDL/HDL, and severity of experimental atherosclerosis.

  • This study was carried out to investigate the effects and characteristics of sausages with red yeast rice added, particularly the Monascus purpureus KFRI 1134 strains, and to decide the optimal quantity of red yeast rice used. The additional rate of red yeast rice which has been used as a material for reducing nitrite, a coupler in meat products were 0, 1, 3, and 5% (w/w). In terms of the effects of the red yeast rice on the color, texture properties, and sensory characteristics of the sausages, the optimal temperature at which color stability was shown was below $100^{\circ}C$, and the addition of 1% red yeast rice resulted in a distinctly attractive color and increasingly improved the red color in the UV-visual Spectrophotometer analysis. However, the addition of over 1% (w/w) resulted in an unattractive color. The red colors also had strong heat stability. The texture properties and taste of the sausages were not affected by the red yeast rice.
