  • In order to design the better brassiere in terms of appearance and functions, various parameters of the materials should be considered; in this study, fatigue properties and subjective sensation of wing materials and its relation to the preference for a brassiere was investigated. After the survey of commercially available products, five elastic fabrics such as cotton, Modal, polyester, nylon, and Tactel, all of which contain 10% polyurethane, were chosen as specimens. Fabric growth were determined to evaluate fatigue properties. Qmax was determined to evaluate the warm-cool feeling. For the sensory test, semantic differential scale which contains 15 adjectives were developed. Fatigue properties were very similar at the 20% elongation irrespective of the duration of tension, but at 40% and 100% elongation, man made fabric showed less growth than cellulose fabrics. The factor analysis showed four factors such as sense of warmth, smoothness, weight and elasticity. Preference of the specimens was ranked in the order of Tactel>Modal>cotton>nylon>polyester.

  • Purpose: For dissecting the possible benefits and usages of Cheonggukjang, five different beans, soybean, black soybean, red bean, chickpea, and lentil bean, underwent the fermentation process along with Bacillus subtilis. Methods: Resultant Cheonggukjang physicochemical and sensory properties such as pH, amino type nitrogen, slime contents, rheological properties, and sensory strength and consumer acceptance were analyzed. Results: Values of pH were found to be highest in Cheonggukjang made with soybean (SC), followed by Cheonggukjang made with black bean (BSC) and Cheonggukjang made with red bean and soybean mixture (RBSC), and lastly Cheonggukjang made with chickpea (CBC) and lentil bean (LBC). Amino type nitrogen values were shown to be highest in SC with a value of $394.74{\pm}28.80mg%$, subsequently were values taken from RBSC, followed by BSC, CBC, and lastly LBC. Slime contents were the highest in SC with a value of $3.44{\pm}0.36%$, with RBSC, BSC, CBC, and LBC without statistical difference. Total colony count was found to show higher value in BSC, SC, and RBSC, in contrast to the lower values found in CBC and LBC. Color was shown to be lightest in CBC and with darker shades shown that of SC, LBC, RBSC, and BSC in descending order. In rheological properties, hardness, adhesiveness, and viscosity were found to be highest in SC. Sensory strength analysis and sticky appearance were highest in SC, with fermented odor being lowest in CBC and BSC. The strength of sweetness, sourness, and umami taste did not show statistical difference, however, bitterness was shown to be highest in LBC and lowest in CBC, SC, and BSC. In the consumer acceptance test, overall acceptance was highest in SC and CBC. Conclusion: In conclusion, SC was found to be the best bean variety for making Cheonggukjang fermented with Bacillus subtilis, however, CBC may act as an alternative for manufacture of Cheonggukjang resulting in sound consumer acceptance.

  • This study was conducted to evaluate the physicochemical characteristics, perform a sensory evaluation of glutinous barley gruel after adding Hizikia fusiformis powder to promote consumption, and identify the best ratio and recipe. The gruel was prepared with rice and glutinous barley powder, and various levels (0, 2.5, 5.0, and 7.5%) of H. fusiformis powder. pH, color, viscosity, and spreadability of the gruel were investigated. A sensory evaluation was conducted by 20 panelists in the categories of color, flavor, taste, texture appearance, and overall preference using a 9-point hedonic scale. The viscosity and pH of the gruel increased as H. fusiformis powder content increased, whereas spreadability of the gruel decreased gradually as H. fusiformis powder content increased. As the level of H. fusiformis powder increased, lightness decreased significantly, whereas redness and yellowness increased. Color, bitter taste, and H. fusiformis flavor of the gruel increased significantly as H. fusiformis powder content increased. On the other hand, sweet taste (delicious taste level) and viscosity were not different among the different gruels. The sensory test results indicated that the gruel with 5% H. fusiformis powder had the best overall acceptability. In conclusion, glutinous barley gruel with 5% added H. fusiformis powder was more acceptable than the others.

  • Objective: This study aimed to develop a value-added product concerning technological and sensory characteristics changes of the use of mechanically deboned poultry meat (MDPM) as meat replacer in lamb and mutton emulsion-type sausages (mortadella). Methods: Sausages were produced with lamb and mutton and with different contents of MDPM. Six treatments, using lamb or mutton and 0%, 30%, and 60% of MDPM in relation to the meat batter, were produced and analyzed for pH, proximal composition, calcium and residual nitrite content, water activity, 2-thiobarbituric acid reactive substances (TBARS), instrumental color and texture profile. The sensory profile of the mortadella's was also evaluated by acceptance test and check-all-that-applies (CATA) analysis. Results: The MDPM addition increased (p<0.05) fat, residual nitrite and calcium content in the all sausage formulations, but mutton sausage had (p<0.05) higher fat and lower moisture content than lamb sausage. The pH, water activity, TBARS index and color was not affected by MDPM additions, while the mutton sausages were significantly redder (higher $a^*$, $C^*$, and lower $h^{\circ}$) and darker (lower $L^*$) than lamb sausages. Adding up to 60% of MDPM reduced (p<0.05) sausages hardness and chewiness. Overall, the meat replacement by MDPM increased the sausages acceptance, but the mutton sausage with 30% of MDPM replacer were the most preferred. Consumers related that pink color, glossy appearance, poultry meat-like taste, soft texture, juicy and greasy mouth feel to all sausages contain MDPM according to CATA analysis. Conclusion: Mutton from culled ewes can be utilized for mortadella production with 30% replacement of lean mutton and fat by MDPM.
