  • This study was performed to develop a therapeutic diet against aging and obesity, using Yangha(Zingiber mioga R.). Before development of a therapeutic diet, we performed cell viability assay, analysis of general composition, macrominerals and antioxidantive activities of Yangha. Based on the findings from analyzing the results, mook using Yangha powder(0~20%) was processed, and tested for quality characteristics such as color values, sensory evaluation and mechanical properties. The result of cell viability assay of myoga, using liver cells, revealed that within the concentration range from 500 ${\mu}g/m{\ell}$ to 10,000 ${\mu}g/m{\ell}$, cell survivability increased in line with the concentration rate. Therefore, it will not be harmful to consume it as food. Regarding the normal substance of myoga, the water substance of myoga was 94%, which exceeds that of ginger and tumeric with 89% and 83%, respectively. As for crude protein, fat, carbon hydrates and ash, myoga contained less than the other two, which I think is due to the high water substance. Regarding the minerals, potassium had the highest contents among macrominerals of 234.74 mg%. As for the antioxidant test, hydroxy radical scavenging activity and superoxide radical scavenging activity were shown. As for the production of Yangha mook(Yangha powder levels were 0~20%) for quality characteristics, the more of the powder, the less the L, but the greater the a and b values. Also, for the material property, an increased amount of the powder, resulted in chewiness and springiness, but less gumminess in a correlated manner. However, there were no significant differences in the springiness and cohesiveness in relation to the powder. For the sensory test, jelly type ZM5 with 5% powder showed highest overall preference. According to the sensory test, based on the powder substance, the jelly with 5% powder showed the highest overall score, including preference.

  • In this study, physio-chemical, mechanical, and sensory characteristics of Tofu containing 0, 0.5, 1.0, and 2.0% Adenophora remotiflora powder were examined. In addition, we examined the potential of utilizing Adenophora remotiflora powder as a functional food material by estimating total phenol contents, electron-donating abilities, and hydroxyl radical scavenging activities of the hot water and ethanol extracts of Adenophora remotiflora powder in the range from 0~2.0%. The total phenol content of the ethanol extracts of Adenophora remotiflora powder was $487.93{\mu}g/mL$ while the that of the water extract of Adenophora remotiflora powder was $403.70{\mu}/mL$. The electron-donating abilities of the ethanol and water extracts of Adenophora remotiflora powder were 75.37 and 86.10%, respectively. The hydroxyl radical scavenging activities of the ethanol and water extracts of Adenophora remotiflora powder were 65.50 and 66.22%, respectively. We also evaluated the quality characteristics of Tofu containing Adenophora remotiflora powder. In the case of color values, as the level of Adenophora remotiflora powder increased, the values of L (lightness) and a (redness) decreased, whereas that of b (yellowness) increased. In the case of mechanical properties, as the level of Adenophora remotiflora powder increased, hardness, gumminess, and chewiness values increased (p<0.05), whereas springiness and cohesiveness values decreased (p<0.05). In the case of sensory evaluation, MPT1.0 scored significantly higher in color, flavor, tenderness, texture, and overall quality. To sum up, Tofu containing 1% Adenophora remotiflora powder showed the highest overall preference.

  • This study was performed to develop patties with quality characteristics using mealworm powder, followed by assessments of general compositions and the branched-chain amino acid (BCAA) levels of the patties. An analysis of the chromaticity of the patties shows that the lightness and yellowness were decreased, whereas the redness was increased, as the amount of mealworm powder was increased. According to the sensory evaluation, the mealworm patty that contain 20% of mealworm powder (M20) showed an overall high preference level. In terms of the mechanical properties, the hardness, gumminess, and chewiness were significantly increased, whereas the springiness and cohesivensee were decreased, as the amount of mealworm powder was increased. The general composition of the M20 consists of 41.84% (moisture), 8.78% (carbohydrates), 34.42% (crude protein), 13.15% (crude fats), and 1.81% (crude ash). The BCAA contents (leucine, isoleucine, and valine) significantly increased in correspondence with the increases of the as mealworm-powder amount regarding the M20, the BCAA composition consists of the following: leucine (2,906.25 mg/100 g), isoleucine (1,459.09 mg/100 g), and valine (1,813.18 mg/100g). The conclusion of this study suggests that mealworm is a potential food material that could possibly replace meat.

The DPPH radical scavenging activities of 25, 50, 100 mg/mL in methanol extracts from Salicornia herbacea L. increased significantly (p<0.05) to 12.8%, 21.6% and 39.1%, respectively. The total phenolic content was $38.58{\pm}4.25{\mu}M$ as tannic acid equivalent for 100 mg/mL of methanol extracts from Hamcho. FRAP value was $448.58{\pm}14.01{\mu}M$ as ascorbic acid equivalent in reducing power. To apply Hamcho to food as a natural antioxidant, pettitoes were prepared with added Hamcho. To manufacture pettitoes added with Hamcho, general quality characteristics of pettitoes added with 0%, 2%, 4% and 6% based on 100 g of pettitoes were determined. In conclusion, mineral components increased according to the added amount of Salicornia herbacea L. Crude protein showed the highest value with 2% added Hamcho. Overall, the addition of Hamcho led to hardening of the meat texture. As a result of measuring color in terms of brightness, redness, and yellowness with chromaticity, the L value (brightness) increased with added amount of Hamcho. There was no significant difference in redness or yellowness. As a result of the sensory evaluation of pettitoes according to addition of Hamcho, the group with 4% added Hamcho showed enhanced overall preference with improved flavor, taste and textural properties.

  • We investigated the quality characteristics of dohwaju (fermented with peach flowers and branches, a Korean traditional alcoholic beverage) containing different sub-ingredients. During fermentation, the inner temperatures of the added sub-ingredient treatments were higher compared to non-treatment, and only peach branches treatment. showed the highest inner temperature. There were no significant differences in the physicochemical results among the treatments. pH decreased from the first mashing day to the second and then increased slightly until fermentation was terminated. Total acidities showed opposite patterns as compared to pH level. Amino acid contents, soluble solids, and alcohol contents increased steadily until the end of fermentation, whereas reducing sugar contents showed the opposite trend. In a preference survey, DB (only peach branches)-treated dowhaju showed the highest evaluation in terms of taste and overall acceptability with walues of $5.07{\pm}1.38$ and $5.57{\pm}1.16$, respectively. Based on the results of this study, we concluded that only peach branches treatment is optimal for the manufacture of dowhaju. We expect that the quality of dowhaju can be improved by providing basic information concerning its manufacture.
