To evaluate the effect of Ulmus devidiana powder, muffins with Ulmus devidiana powder were made after supplementation with Ulmus devidiana powder(0, 5, 10 and 15%(all w/w)). Proximate composition of Ulmus devidiana powder was 7.49% moisture, 2.33% crude protein, 0.84% crude lipid, 66.74% carbohydrate, 14.09% crude fiber and 8.5% crude ash. The sample with 15% of Ulmus devidiana powder showed significantly lower volume compared to other groups. The symmetry of the sample with 5% of Ulmus devidiana powder was significantly lower than that of control group. No significant uniformity changes were observed. The height and baking loss rate of muffins with 15% Ulmus devidiana powder showed lower than that of other groups. But the weight of muffins with 15% Ulmus devidiana powder showed heavier than that of other groups. In color, L value and b value of muffins were decreased as the increase of the Ulmus devidiana powder. a value of muffins with Ulmus devidiana powder were higher than that of the control group. Hardness, gumminess and chewiness of groups with Ulmus devidiana powder were increased significantly as the increase of the amount of Ulmus devidiana powder. No changes of springness and cohesiveness were observed. Color, hardness, root odor and bitter taste intensity increased significantly with the increased addition of Ulmus devidiana powder. Acceptance of appearance, taste and overall acceptability of groups with 10% of Ulmus devidiana powder were significantly higher than that of the control group. As a result, 10% of Ulmus devidiana powder will be ideal to make muffins.
The purpose of this study was to evaluate the quality properties of muffin added with different concentration (0, 1, 3, and 5%) of ginseng leaves powder, which is discarded in the process of ginseng. Density of muffin was the highest at 1.45 g/mL in control, and pH (7.41) was at the highest level as well. There was no tendency at the bottom and upper dimensions according to addition of ginseng leaf powder. The height and baking loss rate of the muffins increased with increase in the powder concentration, but there were no significant differences. The weight of muffins did not show constant tendency, according to addition ratio of ginseng leaves powder. The degree of lightness and yellowness of muffin decreased as the concentration of the powder increased, whereas no significant difference in the redness was found with increased powder concentration. The factors of hardness and chewiness were higher at the control group and cohesiveness was the highest at 0.65 in 3% group, but springiness and gumminess did notshow significant differences. DPPH free radical scavenging activity of muffins was significantly increased with increasing ginseng leaves powder (p<0.05). For the sensory evaluation in 1% group, the intensity of color, smell, taste, softness, and moistness was the lowest, whereas the overall acceptability score of color, smell, taste, chewiness, and moistness was the highest. Thesensory properties of muffin linearly decreased as the concentration of ginseng leaves powder increased. Taken together, the results of this study suggest that ginseng leaf powder is a good ingredient for increasing the consumer acceptability and functionality of cookies.
To evaluate the effect of dried barley sprout powder on muffins, muffins were made after they had been supplemented with barley sprout powder (0, 10, 20 and 30%(all w/w)). The moisture content, crude protein and crude lipid were reduced with an increase in barley sprout powder. The content of crude ash and crude fiber in the control group was significantly lower than those of the samples with barley sprout powder. The pH in the sample with barley sprout powder was lower than that of the control group. The highest specific gravity in the group with 30% of barley sprout powder was 0.84. No significant weight and baking loss rate changes were observed. The sample with no barley sprout powder showed the highest volume. The sample with 30% of barley sprout powder showed the highest uniformity. In color, the L-value and a-value of the control group were significantly higher than those of the other groups. Hardness, gumminess and chewiness of the control group showed the lowest value rather than the other groups. Springness and cohesiveness of the control group were significantly higher than those of the other groups. Crumb color, grass odor and bitter taste showed significant difference among groups. Acceptance of appearance, flavor, taste and total acceptability of groups with 10% and 20% of barley sprout powder did not show any significant difference when compared to the control group. Based on the above results, less than 20% of barley sprout powder would be proper to make muffins.

This study was carried out to investigate the quality characteristics of yanggaeng added with jujube extracts. The jujube extracts were incorporated into yanggaeng at different levels (containing 25%, 50%, 75%, and 100% jujube extracts) based on the total weight of water. To analyze the quality characteristics in the manufacture of yanggaengs, pH, moisture content, density of dough, height, specific volume, baking loss, texture, color, antioxidant activity, total polyphenol content, and sensory test were determined. As the content of jujube powder increased, the pH of yanggaengs decreased but the acidity increased. There was no significant difference in the moisture content depending on the addition of jujube extracts. The color, lightness and redness of yanggaengs decreased as the concentration of the extract increased, whereas the yellowish color increased. As the jujube extracts content increased, total polyphenol content, antioxidant activity, reducing sugar and total tannins significantly increased. The yanggaeng contains jujube extract with acceptable sensory properties, such as color, sweet taste, and overall acceptability, which could be integrated into yanggaengs to meet the taste and functional needs of the consumers.
This research was to examine the differences in post-harvest quality of melons depending on the harvest time after fruit setting. Musk melon cultivar 'K3' plants were grown in glass house conditions with a hydroponic system, and the fruits were harvested at 50, 60, and 70 days after fruit setting. The post-harvest characteristics of melons stored at 7℃ were measured over 32 days. The harvested fruits at 50, 60, 70 days after fruit setting did not differ significantly in weight, height, or size. Solid sugar content was highest in the fruits harvested at 70 days after fruit setting, but firmness, L* value, and respiration rate were highest in the fruits harvested at 50 days after fruit setting. When the harvested melons were stored at 7℃, 'K3' melons responded differently according to the harvest days after fruit setting. The major changes during storage of 'K3' melons can be summarized as follows: Firmness, respiration, moisture content, and general appearance index during storage were highest in the melons harvested at 50 days after fruit setting, but soluble solid content, fresh weight loss, and sensory evaluation were high in the melons harvested at 60 and 70 days after one. During storage at 7℃, there were no significant differences in the appearance of 'K3' melons harvested at different periods after fruit setting, but difference in soluble solid content and taste were noted. It is recommended that the fruit of 'K3' melon plants be harvested about 60 days after fruiting to provide consumers with the highest quality for taste and for storage.
For the consumption extension of Chinese artichoke(Stachys sieboldii MIQ), the quality characteristics and sensory evaluation of white pan bread prepared with different levels of added Chinese artichoke powder(0, 3, 6, 9, and 12%) were investigated. Volume changes of dough, moisture contents(p<0.001), and baking loss rate(p<0.001) decreased with increasing levels of Chinese artichoke powder. In addition, with an increase in the level of Chinese artichoke powder, the volume and specific volume of white pan breads significantly decreased(p<0.001 and p<0.001, respectively) whereas the weight of white pan breads significantly increased (p<0.001). In terms of color, the lightness(L) decreased, but the redness(a) and yellowness(b) increased with increasing Chinese artichoke powder levels(p<0.001). From the texture profile analysis(TPA) of white pan breads, hardness, chewiness(p<0.05), gumminess(p<0.001), and adhesiveness(p<0.001) increased whereas springiness and cohesiveness(p<0.01) decreased according to the levels of added Chinese artichoke powder. In the attribute difference test, crumb color(p<0.001), grain size(p<0.05) decreased whereas grain uniformity, yeast flavor, acridity flavor(p<0.001), plainer taste(p<0.05), sweet taste(p<0.01), acridity taste(p<0.001), firmness, springiness, moistness, softness, and chewiness increased in accordance with levels of added Chinese artichoke powder. Overall acceptability showed that the sample containing 9% Chinese artichoke powder had the highest score (p<0.001). As a result, the optimal ratio of Chinese artichoke powder for white pan bread was determined to be 9%.

We have studied the physico-chemical change and pharmacological transformation of traditional herbal medicines with processing. Evodia fruit (EF) has processed for the purpose of detoxification and reduction of its bitter taste. There are various methods of processing EF in Oriental medicinal reference. Among them, we processed EF according to the method of Sang-han theory, the most famous medicinal reference. We processed EF with washing in hot water, and then dried. Processed EFs(PEFs) were prepared according to the above procedure through repetition of 1,3,5 and 7 times respectively. The contents of weight loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, alkaloids and limonin in non-processed EF (NPEF) and PEFs were examined. The weight loss, and contents of water extract and dilute ethanol extract in PEF showed decrease in proportion to increase of washing time, while the contents of ether extract, total ash and acid insoluble ash showed little change as compared with those of NPEF. And the content of evodiamine and rutaecarpine was not changed distinctly. However, the content of limonin decreased in the final processed material in proportion to increase of washing times with hot water. And the intense of bitter taste in PEF was also reduced. These results were ascribed to the flowing-out of the water-soluble portion. The biological activities of NPEF and PEF were also investigated. In the test of DPPH scavenging effect, xanthine oxidase inhibition effect and TBA-Rs effect, PEF was more effective than NPEF in vitro. Also, both NPEF and PEF showed potent analgesic and anti-inflammatory effects against in mice. Especially, PEF by 3 times washing with hot water was more effective than other PEFs. From these results, it is considered that PEF should be prepared by 3 times washing with hot water.

This study was conducted to evaluate the meat quality of pork produced by feeding fermented rice bran (FRB) (10 to 20%). In the proximate composition analysis there were no significant differences, but the FRB treated groups showed a tendency for higher moisture content and a lower fat content. There were no significant changes found in the physicochemical property analysis, except for cooking loss and water holding capacity, which are the most important factors for estimating meat quality. The cooking loss of the FRB pork was significantly lower than that of the control group (p<0.01). The water holding capacity of the 20% FRB roup was higher than that of the control group (p<0.01). The shear force value of the 20% FRB group was also higher than that of the control group, but the 10% FRB group showed no difference from the control group. The total free amino acid volume of the meat increased, depending on the volume of FRB added. The contents of glutamic acid, glycine, and alanine, which are important factors for taste and flavor, were higher in the FRB groups an the control group. In the sensory analysis, the FRB groups showed high scores for color, aroma, flavor, juiciness, taste, and overall acceptability. Taken together, adding FRB to the feed improved the quality of pork.

The aim of this study was to develop a new salting condition that included added maltodextrin (MD) and grape seed extract (GSE) to ensure the microbiological safety and quality of salted shredded Korean cabbage. Response surface methodology (RSM) was used to analyze the effects of four independent variables (NaCl concentration, salting duration, MD concentration, and GSE concentration). The following response variables were evaluated: reduction in total aerobic bacteria, yeast, and mold counts; weight loss and salt content; and taste, texture, and overall acceptability of salted shredded Korean cabbage. The optimal salting conditions include a combination of 10.09~10.32% NaCl, 9.45~10.00% MD, and 234~300 ppm GSE in a ternary salting solution and a salting duration of 5.68~5.94 hr. This optimal combination reduced total aerobic bacterial and yeast/molds counts by 3.33 and 1.45 log CFU/g, respectively, while maintaining high sensory scores for taste, texture, and overall acceptability of the salted shredded Korean cabbage. In addition, the optimal conditions yielded more acceptable weight loss and salt content characteristics. The results suggest that use of the optimized combination of salting conditions can improve the microbiological safety and quality of salted shredded Korean cabbage used for commercial kimchi production.

The aim of this study was to evaluate the quality characteristics, antioxidant activities, and sensory properties of macaron with Opuntia ficus-indica var. saboten powder (OP). Physicochemical and sensory properties of macaron with different amounts (0%, 2%, 4%, and 6%) of OP were examined. The quality of macarons was evaluated based on spread factor, baking loss rate, color, texture, antioxidant activities, and sensory evaluation. As amount of OP addition increased, spread factor and a value increased, whereas baking loss rate, and L and b values decreased (p<0.05). For texture properties, hardness, springiness, and brittleness were lower as OP content increased while cohesiveness and gumminess were not significantly different (p<0.05). For total polyphenolic contents, DPPH and reducing power significantly increased upon addition of OP at high concentrations (p<0.05). In the sensory evaluation of macarons, scores for color, flavor, taste, texture, and overall acceptance were highest with 4% OP, whereas macaron containing 6% OP showed the lowest scores for taste and texture (p<0.05). These data suggest that addition of 4% OP is the optimal concentration for making macaron.
