  • Noodles were manufactured using chickpea powder to evaluate quality characteristics. Compared to noodles made of wheat flour, noodles made with chickpea powder showed higher contents of protein, lipids, ash, and dietary fiber. Among noodle cooking characteristics, weight, moisture absorption rates, volume, and turbidity decreased significantly as the added amount of chickpea powder increased. Comparisons made of the color of noodles with raw noodles after cooking showed that the brightness (L value) of raw noodles tended to decrease as more chickpea powder was added after cooking, and levels of red (a value) and levels of yellow (b value) tended to increase as more chickpea powder was added after cooking. The texture of noodles with added chickpea powder tended to increase as more chickpea powder was added, such as hardness, springiness, gumminess, cohesiveness, and chewiness.

  • This study was conducted to investigate the quality characteristics of frozen stored mungbean starch gels added with sucrose fatty acid ester (SE). The study showed a delay of gelatinization of mungbean starch by SE addition through the measurements conducted by using Rapid Visco Analyzer (RVA) and Differential Scanning Calorimeter (DSC). In the color of SE added frozen stored gels, lightness (L) and yellowness (b) values were increased compared to those of values measured from freshly prepared gel, whereas redness (a) value was decreased. The addition of 1% SE on mungbean starch gel prevented the color change during frozen storage. Rupture stress and rupture energy of frozen stored gel was higher than those of freshly prepared gel, whereas rupture strain of frozen stored gel was lower than that of freshly prepared gel. The addition of 1% SE on mungbean starch gel prevented the change of rupture characteristics during frozen storage. Texture profile analysis(TPA) characteristics revealed a significant change of the gel texture during frozen storage by showing an increase of hardness of the frozen stored gels compared to the freshly prepared gels with newly discovered fracturability, which resulted to show a large difference of gel texture by showing the disappearance of adhesiveness and large reduction of cohesivenes. The addition of 1% SE on mungbean starch gel prevented the change of TPA characteristics during frozen storage. Scanning electron micrographs showed that network structure of frozen stored gel was more rough than that of freshly prepared gel, and the addition of 1% SE on mungbean starch gel could suppress the breakdown of network structure. Thus the addition of 1.0% SE on mungbean starch gel was appropriate method for remaining gel characteristics during frozen storage.

  • The purpose of this study was to investigate the appropriate water content in high omega-3 fatty acid Saury nuggets for the desirable texture. The approach was made with adding water and onion at various levels (0~20%). 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), lightly battered, and flash fried for 4 min. at $160^{\circ}C$, and then frozen until tested. The frozen nuggets were cooked at $165^{\circ}C$ and subjected to sensory evaluations, texture analysis, and water content analysis during warming (0~60 min), as well as assessments of acid, peroxide, and TBA values (during 10 days of storage at $24^{\circ}C$). In the sensory evaluation, preference for texture was highest in the nuggets made with a 15% onion level. The hardness of the nuggets increased with increasing onion level. Moisture content was highest in the nuggets made with a 20% water level. Changes in hardness during warming (0~60 min) of Saury nuggets containing various water and onion levels increased in nuggets made with the 20% water level. The acid, peroxide, and TBA values of the Saury nuggets made with herbs and oriental herbal extracts decreased up to 10 days of storage.

  • In this study, we propose the automatic extraction method of Rescue Requests from Drone Images. A central object is extracted from each image by using central object extraction method[7] before classification. A central object in an images are defined as a set of regions that is lined around center of the image and has significant texture distribution against its surrounding. In this case of artificial objects, edge of straight line is often found, and texture is regular and directive. However, natural object's case is not. Such characteristics are extracted using Edge direction histogram energy and texture Gabor energy. The Edge direction histogram energy calculated based on the direction of only non-circular edges. The texture Gabor energy is calculated based on the 24-dimension Gebor filter bank. Maximum and minimum energy along direction in Gabor filter dictionary is selected. Finally, the extracted rescue requestor object areas using the dominant features of the objects. Through experiments, we obtain accuracy of more than 75% for extraction method using each features.

  • 본 논문은 사전에 학습된 기억으로 공감각 현상을 지각할 수 있는 의도적인 공감각으로 영상에서 음악으로 변환하는 시스템을 구현하였다. 영상에서 변환정보로 색상(Color), 질감(Texture), 모양(Shape)을 사용하여 음악의 멜로디(Melody), 하모니(Harmony), 리듬(Rhythm) 정보로 변환하였다. 정적인 영상에서 단조로운 음이 반복되는 것을 최소화하고 영상에 있는 정보를 표현하기 위해 색상의 분포도에 따라 확률적으로 멜로디를 선택하여 출력함으로써 자연스럽게 음을 구성할 수 있도록 하였고, 영상에서 질감은 통계적 질감 특징 추출방식인 GLCM(Gray-Level Co-occurrence Matrix)의 7가지 특징으로 하모니의 장조와 단조를 표현하였다. 마지막으로 모양은 영상의 외곽선을 추출한 후 주파수 성분 분석인 허프 변환(Hough Transform)을 이용해 선 성분을 검출하여 각도의 분포에 따라 리듬을 선택하는 방식으로 음악을 생성하였다.

  • Pumpkin (Cucurbita moschata Duch.) seed is rich in protein and sulfur-containing amino acids. Tofu is a protein gel made from soybean, which is rich in lysine but lacking in sulfur-containing amino acids. This study was conducted to investigate the use of pumpkin seeds in tofu manufacture and to determine its quality and texture characteristics. Soybean was substituted with pumpkin seed to obtain pumpkin seed tofu at the following ratios: 10%, 30%, 50%, and 70% (P10, P30, P50 and P70). Tofu manufactured only with soybean was used as a control (Con). The higher rate of pumpkin seed substitution significantly decreased the moisture content and yield rate (p<0.05). In contrast, pH value and turbidity were significantly increased with the increase in the amount of pumpkin seed (p<0.05). The L-value (81.74~79.04), a-value (-0.19~-3.89) and b-value (12.40~9.84) of samples significantly decreased with the amount of pumpkin seed (p<0.05). No significant difference in syneresis was found among the samples (p<0.05). The hardness tended to decrease with the increase in the amount of pumpkin seed. The microstructure analysis revealed that the pore size of pumpkin seed tofu was smaller than that of Con. These results suggest that the pumpkin seed protein is a useful ingredient in the manufacture of tofu. Increasing the pumpkin seed substitution levels improves the texture of tofu.

  • This study was performed to determine the sensory evaluation and mechanical characteristics of lemon red ginseng-pyun. Lemon red ginseng-pyun was made with lemon juice(21.4%), sweet potato starch(6.7%), water(53.3%), sugar(13.3%), honey(5.3%) and various concentrations of red ginseng powder(0, 2, 4, 6, 8, 10%). The quality characteristics of the sample were estimated in terms of pH, color difference, texture profile analysis and sensory evaluation. The pH of lemon red ginseng-pyun showed no significant difference among the different ratios of red ginseng. With increasing red ginseng powder addition, the lightness was significantly(p<0.05) lower, and a value and b values were significantly(p<0.05) higher. In sensory evaluation, with increasing red ginseng powder addition, the color and bitter taste of lemon red ginseng-pyun were stronger, while clarity of the 10% added red ginseng was significantly(p<0.05) lower than that of the 0% added red ginseng. Elasticity, hardness, chewiness, softness. sweet taste and overall acceptability were not significantly different in any group. In texture profile analysis, chewiness, cohesiveness, gumminess and hardness were significantly(p<0.05) increased in the 10% added red ginseng but springiness was not significantly different in any group. Overall acceptability was related to texture, appearance, overall taste and sweet taste of lemon red ginseng-pyun. Therefore, development of lemon red ginseng-pyun with no sugar or artificial sweeteners is encouraged as a healthy diet for diabetes and hypertension patients, because red ginseng is defined as a functional foods.
