  • Freeze-dried Kimchi powder has to be first produced to make Kimchi noodle. Two days, ten days, fifteen days and twenty-five days fermented Kimchi were analyzed respectively to obtain adequate material for freeze-dried Kimchi. Fourteen days' fermented Kimchi with pH 4.0∼4.7 and 0.5∼0.8% acidity was chosen for material for freeze-dried Kimchi, Fourteen days fermented Kimchi was first freeze-dried and powdered. Sensory evaluation was done to decide that 4% addition of the powdered material was optimal. The mixture of Kimchi noodle was analyzed into two perspectives; noodle and Kimchi. The analyzed factors of the mixture was a texture of noodle, color level, Kimchi flavor and its spiciness. The texture of noodle are nutty taste, softness, viscidity and oil flavor. Heavy oil flavor and nutty tasty decreased against the increase of Kimchi powder. Six percent addition of material showed a definite change to the mixture. More than six percent addition destroyed the texture of noodle into near crumbles. Four percent addition of material showed almost same as ordinary noodle texture. Therefore four percent addition of freeze-dried Kimchi was chosen optimal through sensory evaluation.

  • In order to increase the critical current of coated conductor, highly Bi-axially textured substrates are required. Texture uniformity of substrate is also important to fabricate high quality superconducting coated conductor because the amount of current flow along the coated conductor is limited by the defects such as bad textured area. Therefore, we need to evaluate the distribution of texture of Ni substrate along the length before buffer layer deposition on Ni tape. R2R(reel-to-reel) XRD system was used to measure the texture of long Ni substrate continuously. $\theta-2\theta$ scan of 10 m long Ni tape was measured and indicates that some of Ni(111) planes equally remain on Ni(002) textured substrate. The results of continuous Ni(220) $\Phi$-scan indicate that average FWHM is 9$^{\circ}$ within $\pm$1.

  • The objective of this study was to evaluate the effect of different levels of palm kernel meal (PKM), an alternative to corn, on the quality of pork. A total of 72 crossbred pigs ([Yorkshire ${\times}$ Landrace] ${\times}$ Duroc) were assigned into four dietary treatments (PKM level of 0, 4, 8, or 12%). After 12 wk, one pig of median weight in each pen was selected and slaughtered to analyze meat quality. The color, free radical scavenging activity, lipid oxidation, texture, composition of fatty acids, and sensory qualities of pork loin were evaluated post slaughter. When the levels of PKM in the diet increased, the $L^*$-value of pork loin decreased, whereas $a^*$-value and total saturated fatty acids increased. 2-Thiobarbituric acid reactive substance (TBARS) values of pork loin were lower in groups treated with 8 and 12% PKM than in the control group at day 0; this difference, however, was not observed at day 3 and 7. The results of texture analysis showed that increasing the PKM ratio decreased hardness, chewiness, and springiness at day 7. The sensory test, however, indicated no differences between the control and treated groups. These findings show that finisher pigs could tolerate PKM as a replacement for corn; PKM did not negatively affect the quality of pork, indicating that it can be utilized as feed.

  • Using mulberries, a kind of functional food rising these days, we made muffins that people often eat to find the best recipe for mulberry muffins. Also, to find their quality characteristics and show possibility of making new products using mulberries, tests of pH, specific gravity, specific volume, chromaticity, mechanical quality characteristics and preference were done. As more mulberry concentrate was added, pH of muffin dough was decreased and specific gravity was increased. Specific volume was decreased as more mulberry concentrate was added Weight became heavier while volume decreased; and it seems decrease of volume was caused by additives like roughage of concentrate. For chromaticity, all L, a, b values decreased. Acceptance test of muffins with 15% substituted sample showed the highest figure and the rest of the samples were similar to one another in general. For texture, hardness and chewiness were increased as more mulberry concentrate was added, but springiness and adhesiveness were decreased. For example, general interest was the highest in 20% added group, and the order is as follows; 20% > 15% > 10% > 0% > 25%. Addition of mulberry concentrate could lower the quality of products by decreasing their volumes and increasing their hardness. Therefore, this research suggests that the optimum addition rates of mulberry concentrate should be between 15~20%.

  • This study was conducted to evaluate the quality characteristics of sponge cake consisting of 10%, 20%, 30%, 40% and 50% Helianthus tuberosus powder (HTP). With higher HTP contents in sponge cake, pH of sponge cake batter decreased significantly, whereas specific gravity was increased significantly (p<0.05). Meanwhile volume and symmetry indices of sponge cake were inversely proportional to HTP amounts. With higher HTP content in sponge cake, L value (brightness) of crumb significantly decreased (p<0.05), whereas a value (redness) significantly increased (p<0.05). b value (yellowness) of crumb in 40% and 50% HTP sponge cakes were significantly different from b value of crumb in 10%, 20% and 30% HTP sponge cakes. In 10~40% HTP sponge cake, L value, a value and b value all decreased significantly with higher HTP content in sponge cake. However in 40% and 50% HTP sponge cakes, there was no significant difference in any value. For texture characteristics, hardness of sponge cake significantly increased while cohesiveness decreased (p<0.05) with higher HTP content in sponge cake. On the other hand, springiness and gumminess of sponge cake did not change. Sponge cake containing 10% HTP showed the highest values for every organoleptic property. The results of this study suggest that sponge cake containing 10% HTP is the most appropriate for quality characteristics. This study also provides a way to increase the quality, texture characteristics, and organoleptic properties of sponge cake while reducing HTP content to less than 10% in order to qualify consumer taste.

  • This study was conducted to investigate the quality characteristics of guavapyun after the addition of different ratios of extract (0.25, 0.5, 0.75, 1.0%), non-extract and vitamin C. The quality if the pyun containing 0.5% of the guava fruit extract (guavapyun) and vitamin C was higher compared with the quality of the control pyun. In the results of the proximatecomposition, the content of water was high in the control pyun relative to the vitamin C pyun and guavapyun and the carbohydrate, ash, crude lipid and protein content was high in guavapyun. The sweetness, pH and color (L, a, b value) were very high in the samples. The texture, hardness, chewiness and gumminess were significantly high in the control pyun and the adhesiveness and cohesiveness were high in guavapyun. However, there were no significant differences in springiness between the control and the added samples. The total phenolic content was higher in guavapyun (23.57 mg GAE/100 g) than the control pyun (18 mg GAE/100 g) and vitamin C pyun(15.05 mg GAE/100 g). The antioxidant activities determined by the DPPH method and ABTS method was higher in guavapyun (41.37 mM TE/g, 15.35 mM TE/g) than the control pyun (4.43 mM TE/g, 2.17mM TE/g) and vitamin C pyun (11.33 mM TE/g, 4.51 mM TE/g). Using the FRAP method, guavapyun(9.06 mM TE/g) was shown to exhibit a stronger ferrous ion chelating activity than the control pyun (4.49mM TE/g) and vitamin C pyun (7.03 mM TE/g). Thus, the studied indigenous guavapyun was high in both antioxidative activity and total phenolic content.

  • In this study, the Opuntia humifusa f. jeollaensis (Wanggasi-Chunnyuncho) fruit (WCF) was used as a source of viscous dietary fiber and color pigmentation in sausage production to improve quality characteristics, including cooking loss and emulsion stability. Control and treatment sausages were formulated with 0%, 1%, 5%, and 10% WCF powder, respectively, and the following quality measures were investigated: general composition, fiber content, cooking loss, emulsion stability, chromaticity, pH, texture, and sensory properties. The moisture, dietary fiber, and ash contents showed increasing trends (all p<0.05) with increasing concentrations of fruit powder. Conversely, crude protein and crude fat contents exhibited decreasing trends with increasing fruit powder concentrations (p<0.05). Moreover, both the moisture and dietary fiber contents affected cooking loss, water retention capacity, and the sausage texture, causing the cooking loss to decrease, while the water and oil retention capacity increased (p<0.05) with increasing concentrations of WCF powder. Furthermore, hardness exhibited a significant decreasing trend as the concentration of WCF powder increased (p<0.05). This finding suggested that both dietary fiber and viscous materials, along with the protein and moisture content, affected the product hardness. In addition, sensory evaluation of the WCF powder groups showed better results than did the control group, and the strongest results obtained for the group containing 5% fruit powder (p<0.05). Therefore, this study suggests that WCF powder improves the quality of emulsified sausages and can potentially be applied as a naturally-derived additive.

Experimental results showed that the value for infrared water-content analysis of moisture was $85.74{\pm}0.12%$, crude protein was $1.31{\pm}0.01%$, the crude fat $3.91{\pm}0.08%$, the ash $1.83{\pm}0.01%$, carbohydrate $1.08{\pm}0.03%$, and crude fiber $6.12{\pm}0.10%$. For all experiments with Chinese noodles, the grape peels were frozen and dried, powdered, and filtered with a 150-mesh strainer. The grape-peel powder, was added to the composite flour in a proportion of 0%, 1%, 3%, 5%, and 7%. The color of the cooked noodle appeared brown, demonstrating that the L-value decreased as the amount of grape-peel powder increased. The value of a, which corresponds to the level of redness, increased and the cooked noodle appeared brown as the amount of grape-peel powder added increased. The yellowness of the cooked noodle tended to decrease as the value of b, which corresponds to the level of yellowness, gradually (p<0.05). In the texture analysis, hardness was highest in the 7% grape-peel powder group, while the 5% groups showed the highest springness values. The 1% groups showed the highest cohesivness while the 7% groups were the chewiest. The 7% groups had the lowest stickiness values (p<0.05). It terms of sensory quality, the overall surface color, texture and taste were perceived as superior for the 3% grape-peel powder-added groups and lowest for the 7% group (p<0.001). The 3% treatment showed the best overall quality.

  • This study was conducted to evaluate the quality characteristics and antioxidant activities of rice flour sponge cakes containing 0, 20, 30, 40, and 50% Helianthus tuberosus powder (HTP). As HTP content of sponge cake increased, the pH of sponge cake batter significantly decreased, whereas specific gravity significantly increased (p<0.05). Meanwhile, volume and symmetry indices of sponge cake were inversely proportional to HTP amount. Further, with higher HTP content in sponge cake, L and b values of crumbs significantly decreased (p<0.05), whereas a value significantly increased (p<0.05). L, a, and b values of crust significantly increased with higher HTP content. For texture characteristics, hardness, cohesiveness, gumminess, and chewiness of sponge cake significantly increased (p<0.05),whereas cohesiveness did not significantly change. In the sensory evaluation test, rice sponge cake prepared with 10% HTP showed the highest sensory scores in terms of color, flavor, taste, softness properties, and overall preference. The levels of total polyphenol compounds and DPPH radical scavenging activities of rice sponge cakes significantly increased with higher HTP contents (p<0.05). The results of this study suggest that rice sponge cake containing 10% HTP is the most appropriate for quality characteristics and sensory evaluation. This study also provides a way to increase the quality, texture characteristics, and organoleptic properties of sponge cake while reducing HTP content to less than 10% in order to satisfy consumer tastes.
