  • The purpose of this study was to investigate the effects of basil on the quality characteristics of tomato sauce, which is used widely in Western cuisine. The highest pH of 4.29 was observed in the tomato sauce with 4% fresh basil added, while the tomato sauce with 0% fresh basil exhibited the lowest pH of 4.20. The pH of the tomato sauce gradually increased with the addition of fresh basil. The analysis of color differences in the tomato sauce indicated that redness(avalue) decreased with the addition of basil;, whereas consistency and spreadability increased with the increasing amounts of the fresh basil. The sensory evaluation was performed with scoring tests for color, flavor, taste, after taste, viscosity, and overall acceptability by 15 professional panelsists. The tomato sauce with 2% basil showed the best score in the sensory evaluation, except for vicosity. From the above results, the data suggest that an addition of 2% fresh basil to tomato sauce is recommended for commercial use.

  • In this study, the effect of Au-Sn alloy coating on reliability of electrical contacts was investigated via comparison with Au-Co alloy coating. The results show that Au-Sn alloy exhibited lower contact resistance and higher solder spreadability than those of Au-Co alloy after thermal aging. In the case of Au-Co alloy plating, the underlying Ni element diffused into Au-Co layer to form Ni oxides on surface during thermal aging, leading to increased contact resistance and decreased solder spreadability. Meanwhile, for Au-Sn alloy plating, Au-Ni-Sn metallic compound was formed at the interface between Au-Sn layer and underlying Ni layer. This compound acted as a diffusion barrier, thereby inhibiting the diffusion of Ni to Au-Sn layer during thermal aging. Consequently, Au-Sn alloy layer showed better contact reliability than that of Au-Co alloy layer.

  • In this study, frying mix was prepared containing 0.5, 1.0, 1.5 or 2.0% brown rice fiber(BRF). The samples along with a control were then compared regarding their quality characteristics, including pasting properties, spreadability, pick-up ratio, color, textural characteristics, moisture and oil contents, and sensory qualities, all to determine the optimal ratio of BRF. For the pasting properties of frying mix, the control group was evidenced by a significantly higher peak viscosity, through viscosity, and final viscosity than that observed in the BRF samples. Breakdown was the highest at the 1.0% addition level, and time to peak viscosity and pasting temperature were maximal with the 0.5% addition. There was no significant difference in setback among the experiments. Spreadability and pick-up ratio of frying batter were not significantly different among the samples. As the BRF content increased, the lightness, greenness decreased, whereas yellowness increased. The BRF samples presented significantly higher hardness of fried batter than the control group and there was no significant difference in crispiness among the samples. Moisture content of fried sweet potato decreased with increasing BRF and oil content was the maximum on the control group. In the sensory evaluation, appearance, color, flavor, savory taste, yellowishness, coating thickness, off-flavor, and oiliness were not significantly different among the fried sweet potato samples. Bindingness, crispiness, and chewiness were highest in the control samples but minimal at a addition level of 2.0%. The control group evidenced significantly higher overall acceptability than were observed in the BRF samples. In conclusion, the results demonstrated that 0.5~1.0% BRF may prove quite useful as a additive for frying mix in the preparation of fried sweet potato and may provide favorable textural and functional properties.

  • The purpose of this study is to develop value-added functional gruels by adding ginseng powder and fresh ginseng to Tarakjuk which is Korean traditional soup. The results of this study are summarized as follows. Tarakjuk with ginseng powder showed the decrease in the moisture level significantly($\alpha$=0.001) when the amount of ginseng powder added was increased. Tarakjuk with fresh ginseng showed the increase in the moisture level significantly($\alpha$=0.001) when the amount of ginseng was increased. The lightness decreased when the amount of ginseng added increased. Redness and yellowness also tend to increase when the amount of ginseng added was increased. pH and sugar content ratio were not significantly different between the two samples. Tarakjuk with ginseng powder showed the decrease in spreadability when the amount of ginseng powder added raised, and Tarakjuk with fresh ginseng showed the opposite result, so we could figure out that increasement of Tarakjuk spreadability made the decrease of viscosity, and the decrease of spreadability made the increasement of viscosity. The result of acceptance test showed GPT1.0, and FGT3.0 acceptance was the highest. In conclusion, Tarakjuk with 1% ginseng powder and Tarakjuk with 3% fresh ginseng were the optimum for all characteristics when produced.

  • To minimize the waste amount of surface layer kochujang during aging, the effects of the three finishing methods(nothing, salt scatering and Polyethylene film on the kochujang surface) and sunning(conventional aging method) or nonsunning aging(cap covering) on water content, redness and spreadability, film forming yeast occurance and salinity of surface layer kochujang during 120 days aging were investigated. In the case of sunning aging, film forming yeast was not visually found on the surface. The surface layer kochujang was so low spreadability(zero) and very high salinity(18-30%) that could not eat. However, the aging method after PE-film covering on the kochujang surface, and then cap covering(nonsunning) was very effective in keeping of soundness of surface layer kochujang without film forming yeast growth on the surface kochujang, especially was greatly effective in keeping of redness, moderate moisture content and spreadability. The PE-film and cap covering aging were effective in prevention of water evaporation and $CO_2$ release, and in accumulation of ethanol and organic acids between the PE-film and surface layer of kochujang.

  • The effect of onions on the quality characteristics of strawberry jam substituted with 50% fructo-oligosaccharide for sucrose was investigated. Strawberry jams with 10, 20, 30 and 40% onions in place of strawberry were prepared and evaluated for moisture content, pH, total acidity, color, spreadability, soluble solid content, reducing sugar, residual anthocyanin, instrumental texture and sensory characteristics. As the amount of onions increased, moisture content, total aridity, spreadability, soluble solid content, reducing sugar content and residual anthocyanin content of strawberry jams decreased, while pH increased. The lightness and redness decreased with addition of onions, but the yellowness increased. The sensory scores for strawberry jams decreased with the increase of onion content; however, strawberry jams with 10 or 20% onions showed fairly good scores.

  • The physicochemical characteristics of pine nuts gruel were investigated to find the effects of processing condition during the processing. Three-dimensional response surface methodology was applied to investigate effects of ratio of water volume and pine nuts weight to rice weight and heating time on dependent variables of the physicochemical characteristics. The dependent variables in physicochemical characteristics were viscosity (cP), spreadability (cm), pH, soluble solid content (%), color, total sugar (%) and amylose content (%). The F-value of ratio of water volume and pine nuts weight to rice weight and heating time to viscosity were 8.91, 4.54 and 5.02 respectively and they are significantly different at 5% level. The F-value to spreadability were 5.44, 7.88 and 8.04 respectively and they are significantly different at 5% level. These results suggest that water volume, pine nuts weight and heating time greatly affect the viscosity and spreadability of pine nuts gruel. The processing condition also affect the soluble solid content. The changes of the processing condition did not affect the pH of pine nuts gruel. We found that the L, a, b value were affected more by ratio of water volume and pine nuts weight to rice weight than by heating time. The water volume affected more the total sugar and amylose content of pine nuts gruel than pine nuts weight and heating time.

  • The objective of this study is to analyze the influences of fatty alcohols and fatty acids on rheological properties of oil in water (O/W) emulsions using viscosity and rheograms. As the chain length of fatty alcohols and fatty acids lengthened, the viscosity of emulsions was increased. The influence of fatty alcohols on viscosity enhancement was stronger than that of fatty acids. Both stearyl alcohol and cetearyl alcohol, which have carbon chain length similar to lipophilic portion of surfactant used in emulsion preparation, had showed the best increase in viscosity of O/W emulsions. O/W emulsions prepared with fatty alcohols and fatty acids were pseudo-plastic fluid and they showed shear thinning behaviour like as the common cosmetic emulsions. O/W emulsions prepared with cetyl alcohol, cetearyl alcohol and stearyl alcohol were thixotropic fluids and thixotropy increased with an increase in the concentration of fatty alcohols and fatty acids. Also O/W emulsions prepared with fatty alcohols were more thixotropic than those prepared with fatty acids. For the sake of viscosity increase related to O/W emulsions stability and spreadability enhancement related to payoff, it is thought that fatty alcohols are more useful than fatty acids in the O/W emulsions as the emulsion stabilizer.

  • In this study, we investigated the quality characteristics and optimum conditions of porridge containing rice incubated with Phellinus linteus mycelium (PLMR). Composition measurements of PLMR were moisture 13.05%, ash 0.88%, carbohydrate 78.65%, crude protein 6.29%, and crude lipid 1.13%, also glutinous rice composition was moisture 13.99%, ash 0.32%, carbohydrate 77.18%, crude protein 7.85%, and crude lipid 0.66%. The water absorption rate of PLMR increased with increasing soaking time during 6 hours. However, the water absorption rate of glutinous rice increased until 30 minutes of soaking time. The pH of porridge was decreased as PLMR contents increased. The viscosity of porridge was increased as PLMR contents increased, and it was the lowest for the control at 914.77 cP. However, spreadability of porridge was decreased as PLMR contents increased. In terms of color, lightness was the highest for the 50% level, redness was the highest for the 75% level, and yellowness was the highest for the 25% level. In terms of textural characteristics, hardness and fracturability were increased as PLMR contents increased, whereas springiness, cohesiveness and resilience showed reverse results. In terms of consumer acceptance, flavor, appearance, viscosity, delicate taste, and overall acceptability were not significantly different between samples. Hot taste was decreased as PLMR contents increased, whereas grittiness showed reverse results. In conclusion, the results indicate that adding 25~50% PLMR to porridge is optimal for a recipe.

  • The purpose of this study was to investigate the physicochemical and sensory properties of different almond gruels according to the concentration and pretreatment of the almonds. For the physicochemical parameters, pH, sweetness and viscosity decreased with an increasing almond content, while spreadability, lightness, redness, and yellowness increased. In addition, pH, sweetness, spreadability and viscosity decreased by using baked almonds. Also the L(lightness) and a(redness) color values increased by using baked almonds, whereas the b-value (yellowness) decreased. In the sensory evaluation flavor and nutty taste were significantly different(p<.001) among the samples. The overall preference scores also showed significant differences(p<.001) between the different concentrations of almond. The almond gruels containing 40%, 60%, and 80% almond showed higher preferences than the 0 and 20% concentrations.
