  • We evaluated the sensory characteristics of Gangjung base obtained from various manufacturers, using a sensory descriptive analysis. Significant differences were observed for all sensory attributes of Gangjung samples with the exception of 'toothpacking'. Sample A showed high intensities for 'external color', 'external roughness', 'sweetness', 'toasted soybean powder flavor', 'crispness', 'fracturability', 'oiliness', and 'loose particles,' whereas it had low intensities for 'rice flour flavor', 'hardness', and 'toughness' compared to those of other samples. Sample B had more 'sourness', 'butyric acid flavor', 'fermented rice flavor', and 'degree of melting' but lower 'air cell size', 'fracturability', and 'flake roughness'. Sample C showed high intensities for 'expansion', 'hardness', 'crispness', and 'flake roughness', whereas sample D showed low intensities for 'expansion' and 'sourness'. These results indicate that Gangjung base samples are markedly different depending on the manufacturer.

  • This study examined the correlation between a handle evaluation of cosmetic puff textile and a sensory evaluation. The KES-F system was used to analyze the main mechanical factors for the handle evaluation and a statistical method was used for the sensory evaluation. The results revealed different mechanical properties and handle values of the tested cosmetic puff textiles. A material type and structure of the cosmetic textile affected the handle property of the material which is the most important factor for a cosmetic purpose. Particularly, the physical properties of textile material are likely to be important factors for the sensory property of cosmetic material. In addition, the sensory evaluation also revealed different sensory characteristics of the cosmetic efficiency according to the cosmetic puff textile. No close relationship was observed between the mechanical properties and sensory evaluation on the cosmetic puff textiles. The sensory evaluation of a cosmetic efficiency is not only decided by the physical and mechanical characteristics of the cosmetic textile material. Overall, when using textiles used for the cosmetic purposes, it is important to consider not only the proper mechanical properties of the textiles but also the use and sensory satisfaction. Development and selection of the cosmetic textiles should be focused on both the material function and consumer satisfaction.

  • This study was carried out in order to analyze the changes in nitrogen containing taste compounds of traditional Korean soy sauce with varying Meju concentrations (Meju-water ratios of 1:4 and 1.3:4) and ripening periods (up to 2 years), and to investigate correlation between sensory characteristics and taste compound contents via contents assay and sensory evaluation of soy sauce samples. Nitrogen compound contents were higher in 1.3:4 than in 1:4 for all nitrogen compounds. Free amino acid contents were highest in soy sauce ripened for 210 days. Among amino acids, glutamic acid was highest concentration. Nucleotides and their related compound contents did not vary with concentrations and were highest in the sample ripened for 210 days. In direct sensory evaluation of soy sauce, overall taste preference showed positive correlation to sweet taste. Likewise, overall taste preference showed positive correlation to umami, nutty, sweet taste in the sensory evaluation of seaweed soup seasoned with soy sauce. Sensory evaluation score was higher in 1.3:4 than in 1:4. According to the correlation assay of taste compound contents and sensory evaluations, nitrogen compounds (such as amino type nitrogen), amino acids (such as glutamic acid, aspartic acid, and lysine, and etc.), nucleotides (such as AMP, IMP, and etc) had significant influence on the sensory characteristics of soy sauce, and therefore we can conclude that these compounds affect the taste and quality of soy sauce.

  • In order to attain heavier live weight without impairing pork or sensory quality characteristics, carcass performance, muscle fiber, pork quality, and sensory quality characteristics were compared among the heavy weight (HW, average live weight of 130.5 kg), medium weight (MW, average weight of 111.1 kg), and light weight (LW, average weight of 96.3 kg) pigs at time of slaughter. The loin eye area was 1.47 times greater in the HW group compared to the LW group (64.0 and 43.5 cm2, p<0.001), while carcass percent was similar between the HW and MW groups (p>0.05). This greater performance by the HW group compared to the LW group can be explained by a greater total number (1,436 vs. 1,188, ×103, p<0.001) and larger area (4,452 vs. 3,716 μm2, p<0.001) of muscle fibers. No significant differences were observed in muscle pH45 min, lightness, drip loss, and shear force among the groups (p>0.05), and higher live weights did not influence sensory quality attributes, including tenderness, juiciness, and flavor. Therefore, these findings indicate that increased live weights in this study did not influence the technological and sensory quality characteristics. Moreover, muscles with a higher number of medium or large size fibers tend to exhibit good carcass performance without impairing meat and sensory quality characteristics.

  • Changes in sensory and physical characteristics of Wanjajeon (Korean pan fried meat balls) were investigated during chill storage for a hospital cook/chill foodservice system. Wanjajeon was cooked, stored at 2$^{\circ}C$ or 7$^{\circ}C$ for 4 weeks, and reheated by using a microwave oven. The physical characteristics such as texture, color and organoleptic properties were measured. The chewiness of Wanjajeon increased during 4 weeks of storage at both temperatures. Reheating of stored Wanjajeon resulted in a significant increase in the hardness and chewiness. The redness (a value) was significantly increased, while the lightness and yellowness (L and b values) were changed slightly. Sensory evaluation showed that Wanjajeon was acceptable for up to 3 weeks of storage at 2$^{\circ}C$ and to 2 weeks at 7$^{\circ}C$. The sample stored at 2$^{\circ}C$ was more acceptable than that of 7$^{\circ}C$ storage through the whole period.

  • The texture and descriptive sensory characteristics of a Korean rice cake(Karedduk) with added emulsifier were investigated after 2 and 24 hrs of storage at $5^{\circ}C$. The emulsifier, SP, was added at 0, 0.1, 0.5 and 1% levels to the dry rice flour. In the amylogram, the peak viscosity(P), hot paste viscosity(H) and cold paste viscosity(C) of the rice flour with added emulsifier were higher than those of the control. The texture property analysis by a Texture Analyzer revealed that the springiness, cohesiveness and adhesiveness of the Korean rice cake(Karedduk) with added emulsifier were similar to those of the control, while chewiness, gumminess and hardness were lower compared to the control. Also, the hardness by sensory characteristics was significantly different as compared to the control. Lastly, adding emulsifier to the Korean rice cake(Karedduk) was effective at retarding retrogradation.

  • Varied levels of mannitol at 0%, 3%, 6% and 9% were added to the commercial orange juice and physicochemical and sensory characteristics of the juice were investigated. Refractive index of control had $11.3^{\circ}Bx$ and the index was significantly increased to that of the $18.4^{\circ}Bx$ as the addition was increased to the 9% level(p<0.05). The values of pH and the acidity did not show significant differences among varied levels of mannitol added samples. However, sensory characteristics of aroma and sweet flavor were significantly increased as the addition levels were increased showing the values of aroma, from 7.5 to 11.3, and those of sweet flavor from 5.0 to 11.9, respectively (p<0.05). The 9% added level sample had significantly the lowest sour and astringent flavor values of 4.0 and 2.3, respectively.

  • This study was conducted to evaluate the mechanical (texture and color) and sensory characteristics of mulberry leaf sulgi (MLS) and lotus leaf sulgi (LLS) that contained different ratios of ingredients. MLS and LLS with final concentrations of 0%, 1%, 3% and 5% of powdered mulberry and lotus leaf respectively, were prepared. The texture characteristics (hardness, adhesiveness, springiness, cohesiveness, gumminess, chewiness), color values (lightness, redness, yellowness), and sensory characteristics (color, flavor, moistness, taste, brittleness, chewiness and after-taste) of the different sulgis were then measured and compared. With the exception of gumminess and chewiness, the texture characteristics of 0% MLS, 1% MLS and 3% MLS were not significantly different. The sensory characteristics of 0% MLS had the highest scores, whereas those of 5% MLS were the lowest for all factors except for brittleness. However, with the exception of chewiness, the scores obtained from 0% and 1 % MLS did not differ significantly. In addition, 1% MLS and 3% MLS were not significantly different from each other. Furthermore, the texture characteristics of 0% LLS and 1 % LLS were not different significantly, although the characteristics of 1% LLS were significantly different from those of 3% and 5% LLS when springiness, cohesiveness, and chewiness were considered. Additionally, the sensory characteristics of 0% LLS and 1% LLS were not significantly different, with the exception of brittleness, and the characteristics of 1% LLS and 3% LLS were not significantly different, with the exception of taste and after-taste.
