Experiments were conducted to evaluate the effect of an outdoor-grazed raising model on meat composition, physical properties and sensory attributes of Taiwan game hens. Six hundred 1-d old female chicks were raised on a floor for 8 weeks. On day 57, 600 healthy birds, with similar body weight, were selected and randomly assigned to three treatment groups (cage, floor-pen and free-range). The results showed that different feeding models had no effect on drip loss, cooking loss, moisture, crude protein, crude fat, crude ash, zinc and calorie contents in breast meat and moisture content in thigh meat. The free-range group had the lowest fat content in both breast and thigh meat, and the lowest calorie content in thigh meat. The firmness and toughness in both thigh and breast of the free-range group were the highest values (p<0.05). The crude protein, total collagen, zinc and iron contents in thigh meat and total collagen content in breast meat of the free-range group were significantly higher than those of the cage-feeding group (p<0.05). The meat sensory scores of flavor, chewiness and overall acceptability of both thigh and breast meat of the free-range group were significantly (p<0.05) better than those of the other two groups. Moreover, the current findings also indicate that the Taiwan game hens of the free-range feeding model displayed well-received carcass traits and meat quality, with higher scores for flavor, chewiness and overall acceptability for greater sensory satisfaction in both breast and thigh meat. In addition, the thigh meat contained high protein and total collage but low fat, offering a healthier diet choice.

Purpose: This study was conducted to investigate the physical and sensory properties of seasoned powders utilizing tomato. Methods: Tests of salted tomato powder were performed for the physiochemical properties (moisture content, pH value, titratable acidity, color value, salinity content, and solubility content), sensory characteristics and sensory preference. Results: Moisture content of salted tomato powder containing fully ripened tomato (RT) was higher than that of salted tomato powder containing cherry tomato (CT), with the exception of CT 10%. The pH values of RT was relatively high and increased salt addition increased the pH as well. The titratable acidity was opposite the result of pH measurement. The color values of RT was higher than that of CT for the L, a, and b values. The salt content of RT was higher than that of CT. RT 10% showed the highest dissolution followed by CT 10%. In addition, the sensory preference for CT 10% was the highest, with the best scores for appearance and taste. Conclusion: It was concluded that 10% salt addition is the most suitable sensually for the manufacture of salted tomato powder.

The effects of the water extract of beef shank bones on the physical and sensory characteristics of cooked rice for JeonJu Bibimbap were investigated. Five kinds of cooked rice were prepared with 0%(control), 20%, 40%, 60%, and 100% of the beef shank bones extract. An increase in the beef shank bones extract concentration was associated with a lower moisture content of the cooked rice. The color(L, b value) of the cooked rice prepared with the beef shank bones extract became gradually darker during storage at $60^{\circ}C$. In regards to the textural properties of the cooked rice, the hardness increased with the addition of the beef shank bones extract and chewiness was changed in a similar pattern to that of hardness. However, the adhesiveness significantly decreased. In the sensory evaluation, the cooked rice prepared with 20 and 40% of the beef shank bones extract had the best sensory quality for JeonJu Bibimbap.

The effects of the substitution of sugar alcohol for sugar on the sensory properties of mulberry rice cake, 'Bbongseolgy', were evaluated in two phases. First, the relative sweetness of xylitol, erythritol and palatinose to the sucrose in the food systems were examined with paired comparison tests. Second, the sensory properties of the mulberry rice cake containing xylitol, erythritol and palatinose substitution for sugar at a sweetness level equal to sucrose were studied. Sensory analysis for the mulberry rice cake characteristics was conducted and consumer acceptability tests were performed. The physical properties of mulberry rice cake were also examined. The relative sweetness of xylitol, erythritol and palatinose, compared to sucrose, in the solid model food system were 1.00, 0.63 and 0.42, respectively. This result showed that the relative sweetness of xylitol, erythritol and palatinose to sugar was slightly lower than those in the liquid model food system, in which flavor did not influence the sweetness. Mulberry rice cake with erythritol or palatinose had very similar characteristics, with lower fracturability and tenderness, and higher moistness, compactness and chewiness compared to that with sucrose or xylitol. Mulberry rice cake with xylitol was significantly the most fracturable, grainy, and driest, and the least adhesive, among the samples. The consumer test showed no difference in overall acceptability among the samples and consumers perceived differences only in moistness, coarseness and compactness among the samples. Mulberry rice cake with erythritol was the most favored in many characteristics. These results indicate that erythritol substitution for sugar inmulberry rice cake is suitable as a low-calorie rice cake with beneficial functions to improve in the health and texture of the rice cake.

The application of consomme prepared with different ratios of ground beef and ground chicken to improve taste preferences and the cost of foodstuffs was attempted by reviewing fundamental data and the effect on the sensory and physical characteristics of treatment These treatments were prepared with different ratios(9:1(A), 7:3(B), 5:5(C), 3:7(D), 1:9(E) w/w) of ground beef and ground chicken, respectively. Sensory properties were evaluated in the aspects of both acceptability and intensity. From the acceptability aspect, A treatment showed the highest scores in smell, B in mouthfeel and taste, A and B in color and overall acceptability, respectively. In terms of acceptability, B treatment was favored most for color, mouthfeel, taste and overall acceptability except smell. The more the ground chicken, the higher the intensity aspect E treatment showed higher values than A in all the intensity aspects. Moisture contents and crude proteins increased by increasing the mixed ratio of ground beef, whereas crude ash, solid matter and pH increased by increasing the mixed ratio of ground chicken. Tumidity values were the highest in E treatment, whereas the lowest in A. Tumidity values were increased significantly by increasing the mixed ratio of ground chicken. Viscosity increased by increasing the mixed ratio of ground chicken. The highest viscosity was shown in E treatment The colorimetric lightness values(L) decreased and redness(a), yellowness(b) and total color difference values(AE) increased significantly by increasing the mixed ratio of ground chicken. This experimental study showed that A and B treatment had the highest values in overall acceptability. The results of analysis in crude protein, solid matter, tumidity and viscosity were increased by increasing the mixed ratio of ground chicken. B treatment prepared with a ratio of 7:3 of ground beef and chicken had the most favorable sensory quality. These results suggested the basic information to improve acceptability and to save the costs of Consomme recipes for foodservice institutions.
