  • Yackwa was prepared by the addition of different amounts of egg white, and the samples were analyzed by texture profile analysis, Hunter's colorimetry and sensory evaluation during 5 days of storage. Tn texture profile analysis, the hardness, gumminess and chewiness of Yackwa were increased in all the samples during storage and the texture parameters were increased by increasing egg white level. No significant difference was observed in the lightness, redness and yellowness (p〉0.05), but Hunter's color values were slightly increased during storage in all the samples. In sensory evaluation, no significant difference was observed among the samples during storage except the increase of crispiness and overall acceptance by the addition of egg white. The results showed that Yackwa prepared with 10 g of egg white/(100 g of other ingredients ---약과재료 얼마당 10g 첨가인지 명확히 해야 함) had an acceptable sensory quality.

  • To establish an optimum formula for processing wet noodles with steam-dried Hizikia fusiformis flour(SHF), it was incorporated into wheat flour by the ratio of 0, 1, 3, 5, 10 and 20% based on a flour weight. Application of 2% mehthylcelluose(MC) to improve the texture of noodles mixed with SHF was also attempted. Evaluation was performed on the dough rheology and wet noodle quality, such as cooking characteristics, mechanical texture properties, sensory value and shelf-life. Water absorption rate of the composite flour increased linearly as the content of SHF increased from 1% to 10%, and noodle sheet-formation was also acceptable in the same content level. The weight and volume of cooked noodles were decreased, and turbidity of soup was, if exceeding more than 5% of SHF, increased constantly. However, these problems could be remarkably resolved in SHF plus 2% MC. Texture profile analysis of cooked noodles showed an increase of hardness, gumminess, and chewiness up to 5% SHF. The results of sensory evaluation showed that cooked noodles containing 5% SDF were acceptable as much as wheat four noodles in terms of color, texture, taste and flavor. Based on cooking properties, rheological and sensory evaluation, addition of 5% SHF plus 2% MC was suggested to be suitable for making wet noodles, of which the shelf-life was estimated to be 8 days at $5^{\circ}C$.

  • This study aimed to find the optimum instrumental test conditions for the Texture Profile Analysis (TPA) of cooked rice in order to predict the sensory texture attributes (hardness, adhesiveness, chewiness). Sensory evaluation was performed for three kinds of instant cooked rice with university students in their twenties and the results of the sensory evaluation were compared to instrumental TPA patterns. Using partial least squares regression, the instrumental TPA results at a cross-head speed of 1.0 mm/sec and a compression ratio of 70% proved to be an excellent predictor of the sensory attributes of hardness ($R^2=0.99$) and chewiness ($R^2=0.99$). The results at a cross-head speed of 0.5 mm/sec and compression ratio of 30% provided an excellent model for the prediction of sensory adhesiveness ($R^2=0.83$). In this experimental range, sensory hardness and chewiness showed a high correlation with instrumental TPA parameters (hardness, cohesiveness, adhesiveness, springiness, chewiness) with a high cross-head speed and compression ratio, while sensory adhesiveness showed a high correlation with the TPA parameters with a low cross-head speed and compression ratio.

  • The principal objective of this study was to determine the appropriate water content for optimal texture in high omega-3 fatty acid saury nuggets. The approach adopted in this study essentially involved variations in water levels(0{\sim}25%$). The main ingredients of the nuggets included saury mince, mild pizza cheese and hydrated textured soy protein concentrate. The formulated products were molded(dia. 4.5, thickness 1.5 cm, 20 g), battered lightly, flash-fried far 4 min at $160^{\circ}C$ and frozen until they were tested. The frozen nuggets were cooked to $65^{\circ}C$, then subjected to sensory evaluation, texture analysis at 80% deformation, and expressible fluid tests. The moisture contents in the nugget batter and the cooked nuggets were determined. In our sensory evaluation, nugget texture was adjudged the best in the nuggets prepared with a 20% water level(S5). The hardness and chewiness in the nuggets were reduced with increases in the water level. However, when the nuggets contain more than 15% water(S4, S5, S6), we noted no significant differences in the hardness values. The difference in moisture content between the uncooked nugget bat or and the cooked nugget was most profound in the nugget prepared with a water level 25%(S6). The nugget prepared with a water level 25% was also the highest in expressible fluids, and was also highest in internal moisture content. The texture preference of nuggets was correlated positively with moistness(r=0.881) and moisture content(r=0.827), and correlated negatively with firmness(r=-0.870) and cohesiveness(r=-0.839), and these correlations were significant.

  • 8% 녹두전분 gel에서 관능검사의 cohesiveness는 기계적 검사의 어떤 특성치와도 유의적인 상관관계를 보이지 않았으나 관능검사의 shine, clarity, elasticity, hardness, overall quality는 기계적 검사의 특성치들과 유의적인 상관관계를 가진다고 분석 되었다. 10% 녹두전분 gel에서도 8% 녹두전분 gel과 비슷한 양상이었다. 또한 8% 및 10% 녹두전분 gel에서 관능검사의 shine은 기계적 검사의 L, a, b값과는 정의 상관관계이나 clarrty는 L, a, b값과는 부의 상관관계인 점으로 미루어 보아 관능적으로 윤기가 있고 불투명하다고 느낄수록 명도는 높고 적색 및 황색에 가까운 시료로 평가됨을 알 수 있었다. 이상의 결과에서 지방의 첨가는 녹두전분 gel의 texture에 상당한 영향을 미치는 것으로 평가되었고 2%의 지방을 첨가시킨 녹두전분 gel의 texture가 가장 좋은 것으로 평가되었다. 우리의 전통식품인 청포묵 제조시 texture를 좋게 하기 위한 지방의 첨가와 더불어 저장성 및 풍미를 높여줄 수 있는 다진 마늘의 첨가, 고추기름의 첨가와 영양배합 고려 및 간편성을 위한 탕평채 고명의 전분 gel에의 첨가등에 관한 연구를 계속하고자 한다.

  • Background: Texture analysis has been used as a method for quantifying image properties based on textural features. The aim of the present study was to evaluate the usefulness of magnetic resonance imaging (MRI) texture analysis for the evaluation of viable ovarian tissue on the perfusion map of ovarian endometriosis. Methods: To generate a normalized perfusion map, subtracted T1-weighted imaging (T1WI), T1WI and contrast-enhanced T1W1 with sequences were performed using the same parameters in 25 patients with surgically confirmed ovarian endometriosis. Integrated density is defined as the sum of the values of the pixels in the image or selection. We investigated the parameters for texture analysis in ovarian endometriosis, including angular second moment (ASM), contrast, correlation, inverse difference moment (IDM), and entropy, which is equivalent to the product of area and mean gray value. Results: The perfusion ratio and integrated density of normal ovary were 0.52±0.05 and 238.72±136.21, respectively. Compared with the normal ovary, the affected ovary showed significant differences in total size (p<0.001), fractional area ratio (p<0.001), and perfusion ratio (p=0.010) but no significant differences in perfused tissue area (p=0.158) and integrated density (p=0.112). In comparison of parameters for texture analysis between the ovary with endometriosis and the contralateral normal ovary, ASM (p=0.004), contrast (p=0.002), IDM (p<0.001), and entropy (p=0.028) showed significant differences. A linear regression analysis revealed that fractional area had significant correlations with ASM (r2=0.211), IDM (r2=0.332), and entropy (r2=0.289). Conclusion: MRI texture analysis could be useful for the evaluation of viable ovarian tissues in patients with ovarian endometriosis.

  • This study was carried out to develop the processed cheese with the increase of unsaturated fatty acid by substituting different vegetable oils for the improvement of nutritional aspects without reducing its sensory advantage and texture properties. The texture properties(hardness, elasticity, adhesiveness, cohesiveness, brittleness and gumminess), meltability, fat leakage degree and sensory evaluation of the processed cheese were analyzed and compared. The meltability of the processed cheese was measured in the range from 59.7 to 138.3mm, the sample substituted with corn oil showed the lowest meltability but the sample substituted with butter resulted in the highest meltability. The degree of fat leakage had the range from 8.28 to 14.71$\textrm{cm}^2$. The sample substituted with safflower oil showed the lowest fat leakage degree but the sample substituted with butter had the highest fat leakage degree. The sample substituted with butter had the lowest hardness. There was no significant difference in the elasticity between the samples tested. The sample substituted with butter showed the lowest value in adhesiveness, cohesiveness, brittleness and gumminess, respectively. The preference score of the processed cheese samples ranged from 3.22 to 6.59. The texture score ranged from 3.12 to 3.26.
