We investigated the quality characteristics of rice noodles supplemented with turmeric, purple sweet potato, or seaweed (Hizikia fusiforme). RVA (Rapid Visco Analyser), color, water activity, texture, and cooking properties were tested. Initial gelatinization temperature of noodles containing turmeric were the highest. Peak viscosity, holding strength, break down, final viscosity, and set back of noodles containing purple sweet potato were highest, indicating that the gelatinization state was more unstable and retrogradation would occur faster. The L value of the seaweed noodle was the lowest, while the a and b value of the turmeric noodles were $7.3{\pm}0.3$ and $40.2{\pm}1.3$ respectively, higher values than turmeric and seaweed noodles. Water activity of the seaweed noodle was 0.665, higher than turmeric and purple sweet potato noodles. Cooking properties (including weight, volume, and water absorption) and turbidity of seaweed noodles showed the highest growth rate. In terms of texture, the hardness was highest in purple sweet potato noodles, and the cohesiveness and gumminess was highest in seaweed noodles. The quality characteristics of rice noodles supplemented with turmeric, purple sweet potato, or seaweed showed that seaweed noodles were stable in gelatinization and cooking properties.

Jeolpyon was prepared by different moisture addition and then retrogradation characteristics and quality evaluation were investigated during storage periods. In Hunter's color value, lightness of Jeolpyon was decreased, whereas yellowness was increased during storage. In texture profile analysis, hardness, gumminess and chewiness of Jeolpyon were increased during storage and texture parameters were decrease by increasing moisture level. Jeolpyon prepared with 35% moisture addition was slowly retrograded in avrami equation. In the results of sensory evaluation, the parameters were significantly different during storage. The results showed that Jeolpyon prepared with 35% moisture addition had good sensory quality and slow rate of retrogradation.

Rice dumpling shells were prepared with different levels of hydrocolloids, such as hydroxypropyl methyl cellulose (HPMC), and potato starch. After steaming, the physical, sensory, and cooking properties of the shells were measured. Increasing the amount of potato starch decreased the pasting temperature and increased the peak viscosity. With the addition of hydrocolloids, water absorption and cooking loss for the rice dumpling shells decreased significantly. For the textural properties, the rice dumpling shells with hydrocolloids showed lower hardness and higher springiness than the control, and especially, 10% potato starch and 3% HPMC addition (P10H3) improved the texture of the rice dumpling shells the most. The sensory results seemed to be affected more by the addition of potato starch than HPMC, and over 15% addition of potato starch significantly decreased the quality of the rice dumpling shells. By addition of adequate amount of hydrocolloids (3% HPMC and 10% potato starch), the sensory quality of rice dumpling shells can be effectively improved.

This study was conducted to investigate the quality of white pan breads as affected by various concentration of Cordyceps powder. Breads were prepared by addition of 0, 1, 2 and 3% of Cordyceps to flour of basic formulation. The moisture content of white pan breads decreased with increasing Cordyceps powder concentration. The pH of white pan breads also decreased with increasing Cordyceps powder concentration. In color values, with increase of Cordyceps powder concentration, L value decreased and a value increased in the crumb. The weights of breads cooled decreased with increasing Cordyceps powder concentration. The volume and height of dough decreased with increasing Cordyceps powder concentration. However, the specific volume and yield of dough were not significantly different among groups. The baking loss rate was higher in the breads with Cordyceps powder than in the control. In the texture characteristics, hardness and chewiness of breads significantly increased with increasing Cordyceps powder concentration and adhesiveness increased. In the sensory evaluation, when compared to the control, the breads added to 1% of Cordyceps powder was superior to in color and flavor, while was similar to texture and taste.

This study focused on microwave irradiation of dough, raising its temperature to monitor potential variations of dough properties and bread quality, and examined the optimum mixture ratio towards streamlining the bread-making process. According to comparison and analysis on dough properties and bread quality depending on mixture materials, it was found that Salt 2 had the highest dough temperature of all, and Salt 1 had the highest fermentation rate and specific volume but the lowest hardness (i.e. highest softness). Results of sensory evaluation, were that Salt 1.5 scored highest points in sweet taste, aftertaste, and overall acceptance, but there were significant differences among bread samples. Likewise, it was found that Fat 6 had the highest dough temperature, fermentation rate and specific volume of all. Texture analysis, showed that Fat 0 had the highest hardness of all. According to sensory characteristics, Fat 3 scored the highest points in overall acceptance. Based on these results, the optimum mixture ratio of salt and fat for microwave-irradiated bread was found to be 1.5% salt and 3% fat.

The purpose of this study was to compare the physicochemical properties of sausage manufactured with carp (Carassius carassius) muscle and pork. Sausages were prepared using either 100% pork sausage (P10), a mixture of 50% pork and 50% carp muscle (P5C5), or 100% carp muscle (C10). The quality of the sausage emulsion was determined by analyzing approximate composition, pH, instrumental color, cooking yield, water holding capacity (WHC), viscosity, and texture profile analysis (TPA). Moisture content of cooked C10 was significantly higher than that of P10 or P5C5 (p < 0.05); however, protein content of cooked P10 was significantly higher than that of C10 (p < 0.05). The pH of uncooked and cooked C10 was significantly higher than that of P10 and P5C5 (p < 0.05). The cooking yield, WHC, and texture profile analysis of C10 were higher than those of P10 and P5C5 (p < 0.05). In addition, the viscosity of uncooked C10 was higher than that of P10 and P5C5. These results suggest that carp muscle can enhance sausage quality with respect to pH, WHC, cooking yield, viscosity, and TPA.

This study investigated the quality characteristics and antioxidant activity of Yanggaeng prepared with various amounts of watermelon radish flesh (WRF) powder, in ratios of 0 (control), 2.5, 5, 7.5, and 10% of the cooked white bean paste. The proximate composition, pH, sugar content, Hunter's color values, texture analysis, and antioxidative activities of Yanggaeng were examined. Increasing the amount of WRF in the Yanggaeng tended to increase the crude ash, carbohydrate, sugar, total polyphenol, total flavonoids, and anthocyanin contents, a value, DPPH and ABTS radical scavenging activities, with decreasing the moisture and crude protein contents, L and b values, and pH. Texture measurement scores in terms of springiness, chewiness for Yanggaeng showed that 2.5% or 5.0% group was higher than those of the control group. Hardness was higher in the sample groups than in the control group. In conclusion, the results show that Yanggaeng with up to 7.0% added WRF powder can be developed as products, and there is a possibility of developing health functional snack products using WRF powder.

With the advancement and diversification of the bread industry, eco-friendly products with less sugar and salt, and containing functional ingredients are being developed. To develop healthy bread, Korean pine leaf powder was added in different proportions (0%, 1%, 3%, 5%, and 7%), and the quality characteristics of the bread, namely height, moisture, color value, texture, antioxidant property, and sensory characteristics were evaluated. As the amount of leaf powder was increased in the bread, L-value in the range of 53.45~85.05 (p<0.001) and adhesiveness in the range of 0.13~0.32 mJ (p<0.001) decreased significantly, whereas b-value in the range of 16.75~30.74 (p<0.001), total polyphenol content in the range of 466.83~669.13 ug/mL, ABTS- in the range of 0.46~43.23%, DPPH-radical in the range of 1.39~45.76%, scavenging capacities (p<0.001), color in the range of 3.27~5.40 (p=0.017) and texture in the range of 4.33~4.80 (p=0.006) preferences increased significantly. This study could increase the utilization of Korean pine leaf and the production of healthy food with antioxidant properties.

Consumers have become very conscious about their nutrition and well being due to changes in their socio-economic lifestyle and rapid urbanization. Therefore, development of technology for production of low cost and functional meat products is urgently required. One such approach is innovative restructuring technology in which binding of meat pieces still remains the main challenge and extension of product is generally associated with poor binding and texture. Thus, the present study was envisaged as an attempt to solve this problem by the incorporation of flaxseed flour (FF) as bind enhancing agent. The FF was used at three different levels viz., 0.5%, 1%, and 1.5% to replace lean meat in pre-standardized restructured mutton chops formulation. The products were subjected to analysis for physico-chemical, sensory and textural properties. Cooking yield, moisture percentage and fat percentage increased with increase in the level of incorporation of FF, however, protein percent and pH decreased with increase in the level of incorporation. Shear force value of product incorporated with 1.5% FF was significantly higher (p<0.01) than control and product containing 0.5% FF level. Among the sensory attributes, product with 1% flaxseed flour showed significantly higher values (p<0.05) for general appearance, binding, texture and overall acceptability. Hardness showed significant increasing (p<0.01) values with increasing levels of incorporation of flaxseed flour, however all other parameters of texture profile analysis showed a decreasing trend. On the basis of sensory scores and physico-chemical properties, the optimum incorporation level of FF was adjudged as 1%. Products incorporated with optimum level of flaxseed flour (1%) were also assessed for water activity and microbiological quality during the storage period of 15 days. It was found that the extended restructured product could be safely stored under refrigeration ($4^{\circ}C{\pm}1^{\circ}C$) in low density polyethylene (LDPE) pouches for 15 days without marked deterioration in sensory and microbiological quality. Thus, it was concluded that flaxseed flour can be used as a good bind enhancing agent in extended restructured meat products at an economic cost.

Carcass and price traits of 72,969 Hanwoo cows, bulls and steers aged 16 to 80 months at slaughter collected from 2002 to 2013 at 75 beef packing plants in Korea were analyzed to determine heritability, correlation and breeding value using the Multi-Trait restricted maximum likelihood (REML) animal model procedure. The traits included carcass measurements, scores and grades at 24 h postmortem and bid prices at auction. Relatively high heritability was found for maturity ($0.41{\pm}0.031$), while moderate heritability estimates were obtained for backfat thickness ($0.20{\pm}0.018$), longissimus muscle (LM) area ($0.23{\pm}0.020$), carcass weight ($0.28{\pm}0.019$), yield index ($0.20{\pm}0.018$), yield grade ($0.16{\pm}0.017$), marbling ($0.28{\pm}0.021$), texture ($0.14{\pm}0.016$), quality grade ($0.26{\pm}0.016$) and price/kg ($0.24{\pm}0.025$). Relatively low heritability estimates were observed for meat color ($0.06{\pm}0.013$) and fat color ($0.06{\pm}0.012$). Heritability estimates for most traits were lower than those in the literature. Genetic correlations of carcass measurements with characteristic scores or quality grade of carcass ranged from -0.27 to +0.21. Genetic correlations of yield grade with backfat thickness, LM area and carcass weight were 0.91, -0.43, and -0.09, respectively. Genetic correlations of quality grade with scores of marbling, meat color, fat color and texture were -0.99, 0.48, 0.47, and 0.98, respectively. Genetic correlations of price/kg with LM area, carcass weight, marbling, meat color, texture and maturity were 0.57, 0.64, 0.76, -0.41, -0.79, and -0.42, respectively. Genetic correlations of carcass price with LM area, carcass weight, marbling and texture were 0.61, 0.57, 0.64, and -0.73, respectively, with standard errors ranging from ${\pm}0.047$ to ${\pm}0.058$. The mean carcass weight breeding values increased by more than 8 kg, whereas the mean marbling scores decreased by approximately 0.2 from 2000 through 2009. Overall, the results suggest that genetic improvement of productivity and carcass quality could be obtained under the national scale breeding scheme of Korea for Hanwoo and that continuous efforts to improve the breeding scheme should be made to increase genetic progress.
