The purpose of this study was to investigate quality characteristics of roll bread with the addition of Chungkukjang powder(0, 5, 10, 15, 20%). The antioxidative activity of antioxidative substances produced from several bacterial strains isolated from fermented foods were tested by DPPH $(\alpha,\alpha’-diphenyl-\beta-picrylhydrazyl)$ free radical scavenging activity. The most optimal medium condition for the production of antioxidative substance from Bacillus sp. FF-7 was 2% galactose as carbon source and 1% tryptone as nitrogen source. In color values, with increasing Chungkukjang powder content, the "lightness" (p<0.05) decreased in the crumb bread, while the redness(p<0.05) and yellowness(p<0.05) increased. The volume and specific volume of roll bread with 5.0% Chungkukjang powder were the highest(p<0.05). In the rheology measurements for the roll bread, the hardness (p<0.05) decreased with the addition of 5.0% Chungkukjang powder, but then increased with further additions of Chungkukjang up to 10.0%. Highest sensory scores for color, flavor, taste(p<0.05), texture(p<0.05) and overall acceptance(p<0.05) were obtained from roll bread with 5.0% Chungkukjang powder and control. From the results of this study, it was assumed that the development of food products using Chungkukjang is prospective in response to health-oriented consumers.

The purpose of this study is to investigate the physicochemical properties of jelly made from fermented red ginseng concentrate (FRGC) that can be easily absorbed and digested for the health promotion of the elderly. The pH of the jellies tended to decrease with increasing concentration of FRGC. Soluble solid content has significantly higher value when added more than 2%, and the water content of the sample was significantly lower when the FRGC was added 4%. As the amount of FRGC was increased, the total color difference increased, and the hardness of samples decreased significantly. On the other hand, the total ginsenoside contents of the FRGC was 45.50 mg/g. As the concentration of FRGC increased, the content of polyphenol and flavonoids increased. The increasing pattern of polyphenols and flavonoids showed a similar trend. As the content of FRGC increased, ABTS free radical scavenging activity significantly increased (p<0.05), and in the control, the minimum value (62.6 AEAC) and the 4% sample were highest (116.2 AEAC). DPPH radical scavenging activity was like that of ABTS radical scavenging activity. However, there was no significant difference in DPPH radical scavenging activity of 3% and 4% red ginseng jelly.

This experiment was carried out to evaluated biological availability of calcium inthe sea mustard, sea tangle and sea lettuce in the rats. Standard diets were made to supply 0.3% of Ca from CaCO3. Consequently, levels each test ingredients to be added were sets by their Cacontents. The ingredients such as sea mustard, sea tangle and sea lettuce wereadded to basal diet at levels of 15.23%, 12.66% and 23.42% respectively. Ingredients of the basal diet were soybean protein, corn oil, alpha-cellulose, methionine, choline cholride and vitamin and mineral premix. Dextrose was added at level up to 100%. Amount of soybean protein was adjustable to make all the diets isontrogenous. Rats were fed ad libitum the diets for 13 days. The results were summarized as follow: 1. Serum calcium levels of the sea mustard group(15.23%) were higher than those of the other group, but rats fed sea lettuce diets appeared to have the lowest value. 2. Ca concentration in tibia were lower in rats fed with sea lettuce, rather than in those with standard diet. 3. Ca concentration in femur of the rats fed seaweeds did not show any significant difference among groups. 4. In the liver weight in groups fed on the all experimental groups were decreased more than that in the case of the standard diet groups.

Recently, there has been a great deal of public interest in health foods, such as turmeric (Curcuma longa L). In this study, the baking features of turmeric powder were evaluated by making pan bread. To accomplish this, the effects of added turmeric powder on the results of mixograph analysis as well as, the pH and, fermentation rate were measured. In addition, the features of the bread were examined by testing the stickiness of the dough and the TPA of the product using a texture analyzer. Finally, the consumer's preferences were investigated by evaluation of the color difference, crumbScan and sensory evaluation. The results revealed that as the level of turmeric powder increased, the pH decreased. which resulted in the gas possessing capacity of the dough improving and the fermentation persistence of the dough increasing. In addition, the stickiness increased as the turmeric powder content increased. However, there were significant differences among breads produced using different amounts of turmeric powder. Evaluation of the taste revealed that the TP3 group had the higher score than control score and TP7 had the lowest score. In overall preference, TP7 was especially low and the preference decreased as the content of turmeric powder increased.

현미를 이용하여 영지버섯의 균사성장에 적합한 고체배양 조건실험을 실시하였다. 냉침에 의하여 현미는 최종 수분함량이 31%로 10시간만에 hydration time에 도달하였으며, 온침의 경우 40분만에 65%의 수분함량이 되어, 균사배양에 적합한 수분함량에 도달하였다. 수분함량에 따른 균사성장속도 및 균사체량(glucosamine 함량) 측정에서는 수분함량이 65%일 때 균사성장속도 및 균사체량 측면에서 가장 양호한 결과를 나타내었다. 현미에 영지버섯 균사체를 배양한 결과 현미 자체에서 검출되지 않았던 trehalose가 검출되었으며, arabinose함량이 큰 폭으로 증가하였다. 일반미에 영지쌀을 첨가할 경우는 20% 첨가가 가장 기호도가 높은것으로 나타났다.
