  • 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.

  • In order to develop a dandelion (Taraxacum officinale) with natural food applications, the effects of dandelion leaves and roots powder content on the physical, textural and sensory properties of sulggidduk were examined. Dandelion powders of leaves and roots at 0, 1, 2 and $3\%$ were added to the dandelion sulgidduk. In the dandelion roots powder in sulgidduk, the color intensity of L values and the values and moisture content decreased however, the sensory color intensity, dandelion flavor and overall acceptability increased with increasing the dandelion powder content. The sensory overall acceptability indicated the dandelion roots powder content at 3% had the highest overall and flavor scores. As the dandelion leaves content was increased, the moisture contents, lightness, adhesiveness and cohesiveness of sulggidduk decreased, while the sensory color intensity, sensory hardness, hardness of texture properties and dandelion flavor increased. The addition at $1\%$ of the dandelion leaves powder content with the dandelion sulggidduk and the addition at $3\%$ of the dandelion roots powder content with the dandelion sulggidduk showed the highest overall acceptability.

  • 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.

  • Background: In recent years, with the prohibition of antibiotics used as growth stimulants in the nutrition of farm animals, researchers have searched for alternative natural and reliable products in order to be able to sustain the developments experienced during the use of antibiotics and to overcome the possible inconveniences. In this context, studies on evaluation of essential oils in poultry nutrition have been reported to improve the utilization of feed, stimulate the release of digestive enzymes, increase absorption in the stomach and intestines, antimicrobial and anti-parasitic effects and thus, can be an alternative to antibiotics and improve meat quality as well. Indeed, this study has been carried out to explore the effects of the addition of 150 mg/kg capsicum oleoresin (CAP), carvacrol (CAR), cinnamaldehyde (CIN) or their mixture (CAP+CAR+CIN) into the broilers' ration over sensory, physical and chemical properties in breast meat and leg meat. Methods: Experiments were conducted over 400 male and female broiler chicks (Ross-308) in 5 groups (1 control group and 4 treatment groups), each composed of 80 chicks. The control group was fed without feed additives while the second, third, fourth and the fifth groups were fed with 150 mg CAP/kg feed, 150 mg CAR/kg feed, 150 mg CIN/kg feed, and 150 mg CAP+CAR+CIN/kg feed, respectively. Results: Addition of CAP, CAR, CIN or CAP+CAR+CIN had effects on the sensory (of taste, tenderness, juiciness and overall acceptability); physical properties (of $L^*$ value and toughness), the chemical properties (of DM, CF, CP, linoleic, EPA, behenic, MUFA, PUFA and ${\Sigma}n-6$ of the leg meat), the physical characteristics (of toughness and firmness), and the chemical properties (of CF, CP, linoleic, ecosenic, EPA, lignoseric, MUFA and ${\Sigma}n-3$) of the breast meat in comparison to control group. Furthermore, while the treatments had positive impacts on thawing loss, cooking loss and water holding capacity in both breast and leg meat; no effect was observed on pH value and lipid oxidation on day 1, day 4 and day 8. Conclusion: The results strongly suggested that the addition of CAP, CAR, CIN or CAP+CAR+CIN to the rations of the broiler chicks changed the sensory, physical and chemical properties of breast and leg meat. It was also observed that these compounds were more effective when they were added to the ratio as a mixture rather than adding them individually.

  • The purposes of this study were to provide the basic information on the cookies made with barley and oatmeal powder and to establish an optimum formula for the development of cookies with high content of fiber. Cookie samples were prepared with barley and oatmeal at various mixing ratios (2:0, 1:1, 2:1, 0:2), and the chemical properties, textural characteristics, and sensory properties of them were evaluated. The contents of carbohydrate and moisture of barley cookies were higher than oatmeal cookies, but the contents of crude protein, crude fat, crude ash and total fiber of oatmeal were higher than those of barley. The moisture content was the highest in the cookies of oatmeal and the lowest in barley-used ones. The cookie volume was increased by the addition of barley and oatmeal. The results of sensory evaluation showed that the cookies containing barley and oatmeal (2:1) was significantly more preferable in overall acceptability than the others. Hunter color test showed that the lightness was the highest in control, but the redness and yellowness were increased in the cookies with barley and oatmeal compared with the control.

  • This study examined the effects of added amounts of skate (Raja kenojei) flour on the physical and sensory properties, and consumer acceptability of Jook. As the level of skate flour increased the L-values and b-values decreased, and a-values increased. The Jook also had higher viscosity and lower spread ability values as the amount of skate flour increased. Sensory characteristics, such as color intensity, viscosity, nutty taste, and off-flavor increased significantly with the addition of skate flour. A consumer acceptability test indicated that the 3% skate flour group had the highest overall acceptability, appearance, flavor, and texture. In conclusion, to enhance the quality of Jook, a 3% addition of skate flour would be the useful.
