This study was carried out to investigate changes in physicochemical and sensory properties of cooked sausages replaced sodium chloride (NaCl) to potassium chloride (KCl) or magnesium chloride ($MgCl_2$) during storage for 30 days under $4^{\circ}C$. All sausages were prepared with different combination of salts as follow; CTL (1.5% NaCl), KCL (0.9% NaCl+0.6% KCl), MCL (0.9% NaCl+0.6% $MgCl_2$), KML (0.9% NaCl+0.3% KCl+0.3% $MgCl_2$) and PST (1.5% PanSalt). Among sausages moisture content in KML was the highest (p<0.05). Lightness and redness in CTL were lower than those of other treatments, but MCL and KML containing $MgCl_2$ showed higher CIE $L^*$ and $a^*$ values than CTL. The pH in CTL was the highest during storage, however, no significant difference was determined between two treatments, MCL and KML (p>0.05). Crude fat content and water holding capacity (WHC), hardness and cohesiveness of MCL sausages were higher than those of CTL. In sensory characteristics of cooked sausages, saltness in MCL was the lowest during 10 and 20 days of storage (p<0.05). Yellowness in PST was lower than other treatmeants. Gumminess and chewiness of texture property of sausages from MCL and KML were higher than CTL. The results indicate that the replacement of NaCl by KCl improved texture, but meat color was not improved as expected. In contrast, the replacement of NaCl by $MgCl_2$ enhanced color, texture and WHC, whereas partial replacement of NaCl by $MgCl_2$ must reduce bitter taste as compared to sausages manufactured with a NaCl only. Therefore, $MgCl_2$ may be a salt replacing NaCl in cooked pork sausages.

This study was conducted to evaluate sensory properties of sugar cookie containing sucralose. Relative sweetness of sucralose to sucrose in a cookie system was examined with paired comparison tests and the result was applied to low calorie cookie preparation using polydextrose as a bulking agent. Physical and sensory properties and consumer acceptability of sugar cookies containing various levels of sucralose and polydextrose were evaluated. Relative sweetness of sucralose to sucrose was 700 times in sugar cookie. Instrumental hardness and fracturability increased as the levels of replacement with sucralose increased. Spread ratios of sugar cookies where sucrose was partially and totally replaced with sucralose and corresponding amount of polydextrose were higher than that with sucrose only. Intensities of bitter taste, salty taste, hardness and molar packing of sugar cookies where sucrose was entirely replaced with sucralose and polydextrose were higher than that those of the other cookies. Acceptability test indicated 75% replacement with sucralose and adequate amount of polydextrose can be used without harming overall, appearance and flavor acceptability while texture acceptability was slightly lower.
The baking properties of rice bread with different percentages of butter and oil in wet and dry rice flour were investigated. The moisture, damaged starch, mean diameter, pasting properties by amylogram and RVA (Rapid Visco Analyzer), as well as thermal properties by DSC (Differential Scanning Calorimetry) of wet and dry rice flour were analyzed. The specific gravity and color (L, a, b) of the dough, as well as the appearance, color (L, a, b) and texture of the rice bread with different percentages of butter and oil in wet and dry rice flour were also analyzed. As a result, the wet rice flour were composed of a noted higher content in moisture, compared to the dry rice flour (p<0.001). The wet rice flour had lower values of damaged starch, higher values of mean diameter and a higher peak viscosity than was noted in the dry rice flour (p<0.001). The wet rice flour showed a higher degree of hydration and gelatinization than was seen in the dry rice flour (p<0.001). The prevailing principle to utilize the replacement of wet rice flour with oil had a significant effect on the volume, specific volume and hardness of the rice bread (p<0.001). The hardness of the rice bread also showed a decreasing trend as the amount of the added oil was increased into the mixture. These results suggest that the replacement of wet rice flour with 5.8% oil is effective for the production of rice bread.

The objective of this study was to investigate the effects of canola and flaxseed oils on the physicochemical properties and sensory quality of emulsion-type sausage made from spent layer meat. Three types of sausage were manufactured with different fat sources: 20% pork back fat (CON), 20% canola oil (CA) and 20% flaxseed oil (FL). The pH value of the CA was significantly higher than the others (p<0.05). The highest water holding capacity was also presented for CA; in other words, CA demonstrated a significantly lower water loss value among the treatments (p<0.05). CA had the highest lightness value (p<0.05). However, FL showed the highest yellowness value (p<0.05) because of its own high-density yellow color. The texture profile of the treatments manufactured with vegetable oils showed higher values than for the CON (p<0.05); furthermore, CA had the highest texture profile values (p<0.05) among the treatments. The replacement of pork back fat with canola and flaxseed oils in sausages significantly increased the omega-3 fatty acid content (p<0.05) over 15 to 86 times, respectively. All emulsion sausages containing vegetable oil exhibited significantly lower values for saturated fatty acid content and the omega-6 to omega-3 ratios compared to CON (p<0.05). The results show that using canola or flaxseed oils as a pork fat replacer has a high potential to produce healthier products, and notably, the use of canola oil produced characteristics of great emulsion stability and sensory quality.

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.
The principal objective of this study is to develop the optimal recipe for muffins prepared with replacement of sucrose with xylitol. The effect of xylitol on properties of muffins was evaluated in terms of height, volume, weight, specific volume, baking loss rate, crumbScan, colorimeter, sensory evaluation, and staling of muffins during storage days(0, 1, 3, 5 days) was measured by texture analyzer. Hardness of muffins was increased by adding xylitol, significantly during storage. Lightness(L value) of crust was increased significantly as the contents of xylitol increased. According to sensory evaluation, the muffins(control group) without xylitol had highest score in appearance and texture. In flavor, taste and overall acceptance, muffins with 25% of xylitol showed the best result but were not significant between the muffins(control group).
Mineralogical studies of ore and alteration minerals have been conducted for the Hugo Dummett porphyry copper deposit. The Hugo Dummett porphyry copper gold deposit is located in the South Gobi region, Mongolia and currently being explored. This deposit divided into the Cu-rich Hugo Dummett South and the Cu-Au-rich Hugo Dummett North deposits. The Hugo Dummett deposits contain 1.08% copper(1.16 billion tonnes in total) and 0.23 g/t gold(Oyunchimeg et al., 2006). Copper-gold mineralization at these deposit are centered on a high-grade copper(typically>2.5%) and gold(0.5-2 g/t) zone of intense quartz stockwork veining. The high grade copper and gold zone is mainly within the Late Devonian quartz monzodiorite intrusions and augite basalt, also locally occurs in dacitic rocks. Intense quartz veining forms a lens up to 100 m wide hosted by augite basalt and partly by quartz monzodiorite. Although many explorations have been carried out, only a few scientific works were done in the Oyu Tolgoi mining area. Therefore the nature of copper-gold mineralization and orgin of the deposit is not fully understood. Copper-gold mineralization in the Hugo Dummett deposits occurs in dominantly quartz monzodiorite and minor augite basalt, dacitic rocks and locally biotite granodiorite. Chalcopyrite, pyrite, bornite, molybdenite, tennantite, tetrahedrite, enargite, sphalerite, chalcocite, covellite, eugenite, galena and gold occur as main ore minerals in the Hugo Dummett North and South deposits. These sulfides occur as: (1) a vague vein-like trail 1-3cm long and 2-3 mm wide, (2) minute, discontinuous cracks within quartz(micron scales), and (3) irregular blebs/spots(micron scales)and (4) disseminated within the sericite and plagioclase, commonly concentrated in the quartz. Sulfide minerals commonly display as a replacement, intergrown and minor exsolution texture in the both of the Hugo Dummet deposits.
Beer production with rice or other malt substitutes suffers from a lack of suitable enzymes for saccharification. For this reason, rice nuruk (fermentation starter) was tested as a starch replacement for malt in the saccharification process of beer production. The results of this study show that the enzyme activities of rice nuruk made with brewing fungi were higher than those of malt. Saccharification and glucoamylase activities were high in Aspergillus awamori KCCM 30790 and α-amylase activity was high in Aspergillus oryzae CF1003. Overall, malt beer had significantly higher alcohol, pH, total acid, volatile acids, amino acids, free amino nitrogen, bitterness unit and ΔE than rice nuruk beer. Where as Aspergillus awamori KCCM 30790 beer had significantly higher soluble solids, reducing sugar than malt beer. According to a sensory evaluation, malt beer was better color, flavor and Aspergillus oryzae CF1003 beer was better taste, texture, overall acceptability than other beer. Therefore Aspergillus awamori KCCM 30790 beer was suitable considering enzyme activities (saccharification, glucoalmylase) and physicochemical characteristics (soluble solids, reducing sugar). And then Aspergillus oryzae CF1003 beer was suitable considering sensory evaluation (taste, texture, overall acceptability). Therefore rice nuruk like Aspergillus awamori KCCM 30790 and Aspergillus oryzae CF1003 were suitable as a substitute material that can replace for malt in beer proceccing.
Objective: The sinus floor elevation procedures have been used to facilitate implant placement in the severely atrophic posterior maxilla. Many variables may have an influence on the outcomes of the sinus floor elevation in combination with implant treatment. The aim of this study was to analyze survival rate of implants placed in the edentulous maxillae of patients in whom sinus floor elevation was undertaken according to variables. Materials and Methods: It consisted of 96 patients(50 male and 46 female), ranging in age from 31 to 70 years(mean 49 years), who underwent sinus floor elevation procedure(94 implants in left side and 106 implants in right side) from 2001 to 2002. A total of 200 implants were placed in the grafted sinus(73 implants in lateral approach and 127 implants in crestal approach). All implants were restored by fixed prosthesis. All patients were healthy. Follow-up periods for implants were between 48 to 60 months. Results: The cumulative survival rate of implants was 91.5%. Gender, age and operation site did not have an influence on the survival rate. There was statistically significant differences for the implants which placed in less than 4 or 5 rom residual bone height, the survival rate was 60%, 81.4% respectively (p<0.05). There was no statistically significant difference of implants survival rate ac- cording to approach technique. The survival rate for 100% autogenous bone grafts was lower with respect to composite grafts containing autogenous bone and 100% substitutes. The survival rate for hydroxyapatite-coated implants was statistically significant lower than other textured group (p<0.05). Conclusion: Residual bone height, surface texture and graft materials have an influence on the survival rate. To use autogenous bone as a part of a composite bone replacement, implant texture which leads to more favorable implant-bone interface were necessary. To determine residual bone height for initial implant stability was important.
Today, energy bars are consumed not only as snacks but also as meal replacement foods. Convenience and nutritional supplementation are the main factors accounting for the increasing use of energy bars. Two hundred Chinese customers who attended the China Fisheries & Seafood Exposition in China, and had no inhibitions about consuming cereal bars were selected. The questionnaire was composed of CATA choices that selected both the reasons for liking and disliking four different types of cereal bars, namely topokki flavor (hot pepper paste), seaweed flavor, kimchi flavor, and ginseng flavor cereal bars with 10% of dried anchovy content produced by BadaOne Co. (Seoul, Korea). The purpose of the study was to investigate Chinese consumer's attitudes and acceptance of different flavored cereal bars containing protein and calciumrich anchovy. For the selected Chinese customers, the acceptance score for the seaweed flavor was the highest, followed by topokki, red ginseng, and kimchi. The acceptance for the topokki flavor was higher than for seaweed for the attributes of color except for general acceptance, flavor, aroma, and texture. The results of the survey showed that the acceptance of kimchi was the lowest, contrary to earlier predictions. The results of the Check All That Apply (CATA) analysis showed that the reasons for liking the seaweed & anchovy flavor were the most diverse, and there was no reason chosen for disliking this flavor. The reasons for liking this flavor were listed as sweet flavor, healthy, seafood flavor, malty flavor, texture, new/unique, and umami. In the case of topokki and kimchi, the reason for disliking the flavor was umami, and in the case of red ginseng, the ginseng flavor was the reason for both likes and dislikes. CA analysis showed that both the flavor and emotional factors were positive for seaweed & anchovy and topokki, but negative for red ginseng. As a result, seaweed & anchovy flavor, which is familiar to the Chinese people, should be the first cereal bar considered for a launch.
