The purpose of this study was to investigate the effects of skate (Raja kenojei) flour on the functional and sensory characteristics of Mandupi. Mandupi samples were prepared with wheat flour along with the addition of different amounts of skate flour, followed by functional measurements and sensory evaluations. According to the amylograph data, the composite skate flour-wheat flour samples had increased gelatinization temperatures with increasing skate flour content; whereas initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. In terms of color values, L and b values decreased, but the a-value increased with increasing skate flour content. Furthermore, the addition of skate flour increased hardness, springiness, chewiness, and adhesiveness in the samples. Overall, based on sensory evaluations, the Mandupi containing 5% skate flour was preferred over the other samples.

Aerobic plate counts(APC) gram-negative bacterial counts (GNC) and sensory evaluations on chic-ken carcasses during retail and refrigerated storages (3$\pm$1$^{\circ}C$ and 1$0^{\circ}C$) were evaluated. APC and GNC on whole chicken in retail store after storage of 7 days at 3$\pm$1$^{\circ}C$ increased to 3.11 and 3.89 log units com-pared to the initial controls. APC and GNC on whole chicken after storage of 7 days at 1$0^{\circ}C$ increased to 5.43 and 5.03 log units. Sensory scores of chicken carcasses obtained from retail store were in the "liked less" category after storage of 7 days compared to fresh controls. These results indicated that chicken carcasses during refrigerated (1$0^{\circ}C$) storages rapidly allowed the growth of aerobic spoilage bacteria dur-ing storage period which cluld not be microbiologically acceptable after of 7 days of 7 days.

This study analyzed the quality characteristics of nutritional bars with varying concentrations (0, 0.5, 1.5, 2.5%) of Enteromorpha intenstinalis powder added. To achieve this, color analysis, an assessment of DPPH radical scavenging activities, and sensory evaluations were performed. The results revealed that as the amount of Enteromorpha intestinalis powder (EIP) increased, pH and lightness values decreased. DPPH radical scavenging activities of 75.26%, 56.11%, 71.59%, and 62.49% were exhibited for the 0%, 0.5%, 1.5%, and 2.5% concentrations, respectively at 50 mg/mL. Significant differences were observed between the samples with respect to the color, appearance, texture, taste, and overall preference for the nutritional bars. Overall preference was highest for the nutritional bar with 1.5% Enteromorpha intenstinalis powder added. Therefore, adding 1.5% of Enteromorpha intenstinalis powder to a nutritional bar is most suitable for enhancing preference and quality characteristics.

Microbiological and sensory evaluations of chicken wings treated with acetic acid and trisodium phosphate(TSP) during retail(1${\pm}$2$^{\circ}C$) and refrigerated storage(4$^{\circ}C$). Chicken wings(average weight of 15${\pm}$2g per leg) were treated with 0.5∼2% aerobic plate counts(APC) on the surface of chicken wings for storage of 16 days at 4$^{\circ}C$. During storage of 12 days at retail store(1${\pm}$2$^{\circ}C$), the treating chicken wings with 7.5∼10% TSP solutions for 10 min showed significantly inhibitory effect in preventing the growth of aerobic microbes. For odor and appearance scores, chicken wings treated with 0.5∼2% acetic solutions resembled untreated wings for storage of 16 days at 4$^{\circ}C$. However, both odor and appearance scores of chicken wings treated with 2.5∼10% TSP solutions were similar to those of untreated wings for storage of 4 days, and a higher in the storage of beyond 8 to 12 days at retail store.

The aim of this study was to investigate the effects of adding different amounts (0, 4, 8, 12, 16%) of green laver powder to Sulgidduk, a traditional Korean rice cake product, in terms of textural properties and sensory characteristics. During storage, moisture content was reduced less in the green laver-added samples as compared to the control group. With increasing additions of green laver powder, L-values decreased, a-values increased significantly, and b-values decreased; however, no changes were observed in the control group. In the mechanical evaluations, hardness increased less during storage in the green laver added samples than in the control group. Adhesiveness did not differ significantly by the addition of green laver powder. Springiness, cohesiveness, gumminess, and chewiness showed significant differences, and increased or decreased repeatedly during storage. In the sensory evaluations, the 16% green laver group received the highest scores for color, flavor, and taste Moistness and softness were evaluated higher in the green laver groups as compared to the control group; however, moistness, softness, and elasticity did not differ significantly during storage.

The purpose of the study was to perform research a proximate analyses and sensory evaluations for sulgidduk over a storage period, where the sulgidduk contained added with buchu powder added at 1%, 2%, and 3% concentrations. The general composition of the buchu powder was 34% crude protein, 1.8% crude lipid, and 21.8% crude fiber while the moisture contents of the buchu powder was 2.71%. The moisture contents of the sulgidduk samples over the storage period ranged from 34% to 38%. Color and moisture changes were not significant (p<0.05) during storage, while the values showed significant decreasing trends (p<0.05) with greater additions of buchu powder. In terms of textural characteristics, hardness, cohesiveness, gumminess, and chewiness decreased significantly (p<0.05) with greater concentrations of buchu power, while adhesiveness and springiness showed no significant differences(p<0.05). Based on the sensory evaluations, overall preference was high for the 3% buchu powder sample. This sample received high scores on flavor, color, taste, chewniess, and moisture, suggesting that adding 3% buchu powder would be feasible for making sulgidduk.

The purpose of this study was to investigate the effects of Curcuma aromatica powder on the functional and sensory characteristics of Mandupi. Various Mandupi samples were prepared with wheat flour along with addition of various amounts of Curcuma aromatica powder, after which instrumental characteristics and sensory evaluations were investigated. According to the amylograph data, the composite Curcuma aromatica powder-wheat flour samples showed increased gelatinization temperatures with increasing Curcuma aromatica powder content, whereas initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. In terms of Hunter's color values, L value decreased while a and b values increased with increasing Curcuma aromatica powder content. Besides cooked weight, cooked volume and turbidity of Mandupi increased as the addition level of Curcuma aromatica powder increased. In terms of textural characteristics, addition of Curcuma aromatica powder increased springiness, chewiness, and brittleness, whereas springiness and adhesiveness decreased. Based on sensory evaluations, the overall preference of Mandupi with 3% added Curcuma aromatica powder was higher than that of control.

The effect of trisodium phosphate and chitosan on aerobic plate counts, generation time, pH, shear force, and sensory evaluations in Korean beef loins stored at 4 or 10$^{\circ}C$ was assessed. The beef loins were treated with 5∼7.5% (w/v) trisodium phosphate and 1% (w/v) chitosan at exposure times of 10 min. The generation time of aerobic microorganisms on the beef loins increased with higher trisodium phosphate levels during storage at 4$^{\circ}C$. During storage at 10$^{\circ}C$, treatments of 5% trisodium phosphate and 1% chitosan were the most effective for preventing the growth of aerobic spoilage microorganisms. Shear values of the beef loins treated with trisodium phosphate and chitosan or chitosan alone were lower than those of trisodium phosphate during storage at 4$^{\circ}C$. The results of sensory evaluation indicated that the beef loins treated with trisodium phosphate and chitosan were in the \"liked less to typical\" category for odor and appearance scores compated to the controls during storage at 4$^{\circ}C$.

This study was conducted on four types of laver soup prepared using recipes from Gangwon-do (GW), Gyeongsangnam-do (GN), Jeollanam-do (JN), and the media (MD). Salinities, soluble solids, free amino acids, color values, turbidities, and pH values of soups were measured, and sensory evaluations were done. pH values were significantly higher for GW and GN recipes than the JN and MD recipes (p<0.05). The salinities of JN and MD were significantly higher than those of the other soups (p<0.05). Regarding soluble solids, JN had the highest at 2.64°Brix, whereas GW had the lowest at 0.86 °Brix (p<0.05). GW and JN had higher concentrations of valine, phenylalanine, and glutamic acid (p<0.05). JN had significantly higher redness (a) than the other soups but significantly lower lightness (L) and yellowness (b) (p<0.05). Regarding transmittance, GW had a significantly higher value (67.67%T) than the other soups. JN and MD had higher acceptability results than GW or GN in terms of flavor, mouthfeel, and overall acceptability. Sensory intensity evaluations revealed that JN and MD had higher "soy sauce aroma" and "saltiness" and a greater "broth turbidity" than the other soups. These results indicate that the physicochemical and sensory characteristics of regional laver soups differ.
