  • In this study, the breads with medicinal herbs (MH) composites showing cognitive function were prepared and their characteristics were examined. Fifteen kinds of medicinal herbs were extracted with hot water and divided into 3 groups (MH-1, MH-2, MH-3) based on their contents. All groups showed cognitive function in terms of promoting muscarinic receptor, NMDA receptor and acetylcholinesterase inhibition. In the preparation of breads containing MH extracts of various contents (0, 10, 20, 30, and 50%), there were no significant difference among loaf weight of all groups, but loaf volume of all groups were significantly (p<0.05) decreased with increasing content of MH extracts compared to the control group. The "a" and "b" values of bread crumb increased with the content of MH extracts while "L" value decreased, but these values of bread crust were similar to the control group. The most improvements in hardness, fracturability, cohesiveness, gumminess and chewiness of bread were noticed by the addition of 10$\sim$20% MH extracts, while adhesiveness and springiness of bread were the most by the 30% addition ones. Through the sensory evaluation, it was revealed that appearance, mouth feeling, taste, overall preference and crumb texture of bread were not significantly different (p<0.05) between control and those with the 10% addition ones. Therefore the 10% addition ones, which got similar scores to control, will make the most desirable product.

  • It has been known that the mulberry leaf is effective in many diseases. Nowadays, the pharmacological effects on diabetes mellitus of mulberry leaves have been confirmed and they are used for many aspects. And Mulberry leaves are also hewn to be effective in the prevention of diabetics, because of their rich amino acids and fibers. From the results of sensory evaluation, the addition of up to $0.5\%$ MLP(mulberry leaf patty), to the chicken patties induced no significant differences in texture, appearance, and color until $0.5\%$ adding of MLP. However, chicken patties with added $0\%$, and $0.25\%$ added of MLP were shown have the highest acceptability, so these levels were thought to be the proper addition amounts of MLP to the chicken patty. Brightness(L) of these patties was the highest in the $0\%$ group as (55.63) and decreased with increasing adding amount of MLP level. Redness(a) was decreased with increasing adding amount of MLP and appeared as ueenish. Yellowness(b) was the lowest in the $0\%$ MLP addition group as (13.31) and increased with increasing MLP level. Hardness was the highest in the chicken patty with $0.25\%$ added MLP, and the lowest value in the chicken patty with $0.5\%$ added MLP. Cohesiveness was the highest in $0\%$ added MLP added chicken patty and springiness was the highest in $0.5\%$ added MLP added chicken patty. But not significantly. Also Brittleness was similar among the various chicken patties with no significantly difference. As for the composition of fatty acids in the chicken patties with added MLP, saturated fatty acids were decreased and unsaturated fatty acids were increased with increasing MLP Especially, the contents of essential fatty acids showed a largely increasing tendency in the chicken patties with added MLP Linoleic acid, linolenic acid, and arachidonic acid were increased to $9.38mg\%,\;0.65mg\%\;and\;1.28mg\%$, respectively in chicken patty with $1.0\%$ added MLP.

  • This study examined the quality characteristics of Yanggaeng added with tomato powder (0, 5, 10, 15, and 20%) and oligosaccharides instead of red beans and sugar. The moisture content of tomato Yanggaeng was 45.89~33.64% and was highest in the control group. The pH ranged 3.96~6.24 and significant decreased with the addition of tomato powder. Hunter's color value, lightness (L value) were the highest in Yanggaeng added with 20% tomato powder. Redness (a value) increased with tomato powder content, except for 20% tomato powder. Yellowness (b value) significantly increased with tomato powder content (P<0.05) but decreased with 20% tomato powder. In the texture profile analysis, hardness, cohesiveness, gumminess, and chewiness significantly decreased (P<0.05) with the addition of tomato powder. Total soluble solid content ($^{\circ}Brix$) was the highest (5.16) in the control group, whereas that of tomato Yanggaeng ranged 4.46~4.92 and significantly decreased (P<0.05) with the addition of tomato powder. The antioxidative activity based on 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of Yanggaeng increased with the concentration of tomato powder, although those of Yanggaeng added with 15% and 20% tomato powder were not significantly different (P<0.05). Yanggaeng added with 5 and 10% tomato powder showed acceptable sensory properties, including color, flavor, sweet taste, sour taste, and overall quality. In terms of sensory evaluation and antioxidant activity, the results show that Yanggaeng added with 10% tomato powder was the best, but more research should be conducted in order to improve sensory acceptability.

  • This study was conducted to investigate the effect of 0.5% calcium lactate(CaL) on the fermentation of dough and quality and shelf-life of bread. Calcium lactates(CaL-A and CaL-P) were prepared from ash of black snail which contained shell and tissue together(ABS) and powder of the snail(PSB). pH of dough with the CaLs were higher than that of the control md, volume of the dough, loaf volume of bread were lower than those of the control products. But the volumes were almost the same when the pH of the dough were adjusted to pH 5.5. Mean calcium contents of treated bread (39.36~49.70 mg/100 g) were higher than that of control products(13.43 mg/100 g). There was no difference in Hunter $L^{*}$, $a^{*}$, $b^{*}$ values between the control and the treated group. Hardness and gumminess of CaL-A treated bread were the highest, but springiness and cohesiveness were the lowest. All the attributes showed no difference in case of pH adjustment(pH 5.5). The smaller pore and larger air cell with rough surface were observed in the CaL treated bread by SEM analysis. Sensory scores of CaL treated bread showed relatively lower values than those of the control products, but the scores increased by pH adjustment. The shelf-life of bread with CaL-P and CaL-A at 2$0^{\circ}C$ were 4 and 3 days, respectively, while that of the control group 1 day.day.y.

  • In this study, sponge cakes were prepared with 3, 6, 9, 12, and 15% red ginseng marc powder. The samples and a control were then compared in terms of quality characteristics, including batter viscosity and specific gravity, moisture content, water activity, volume index, weight, color, textural characteristics, and sensory qualities, in order to determine the optimal ratio of red ginseng marc powder in the formulation. The batter samples containing 0, 12, and 15% red ginseng marc powder had significantly higher viscosity than the other samples. Specific gravity of batter was not significantly different among the batter samples. The control group presented significantly higher moisture content as compared to the samples containing red ginseng marc powder samples. Water activity, volume index, and weight of all samples were not significantly different among the samples. In terms of crust color, lightness, redness, and yellowness of the crust samples decreased as the level of red ginseng marc powder content increased. For the crumb color, lightness and yellowness decreased, and redness increased, with increasing red ginseng marc powder content. Hardness, cohesiveness, gumminess, and springiness were not significantly different among the samples; however, the red ginseng marc powder samples had significantly higher chewiness than the control group. In the sensory evaluation, as the content of red ginseng marc powder increased, scores for color, flavor, softness, overall acceptability, moistness, and egg-flavor decreased, while scores for red ginseng taste, bitterness, astringency, and off-flavor incresed. Overall, the 3 and 6% red ginseng marc powder samples obtained fairly good sensory scores. In conclusion, the results indicate that adding $3{\sim}6%$ red ginseng marc powder to sponge cake is optimal, providing good physiological properties as well as reasonably high overall consumer acceptability.
