        This study compared the physicochemical properties of soybean curd residue and black soybean curd residue produced by hot air-drying and freeze-drying. Regardless of drying method, the crude protein, crude ash, crude fiber contents, pH, L, a, b color values and water soluble index were higher in soybean curd residue, whereas total polyphenol contents and antioxidant activity were higher in black soybean curd residue. Significant differences in water absorption index, oil absorption capacity and emulsion activity were observed between soybean curd residue and black soybean curd residue in freeze-drying. On the other hand, the emulsion stability was not significant difference in both hot-air drying and freezedrying. The crude protein and crude fiber contents of soybean curd residue were not significant difference between hot-air drying and freeze-drying. Freeze-drying resulted in higher crude ash contents, pH, water absorption index, water soluble index, oil absorption capacity, emulsion activity and emulsion stability than hot-air drying. Hot-air drying have caused significantly higher water contents, water activity, total polyphenol contents and antioxidant activity in soybean curd residue than freeze-drying. In conclusion, soybean type and drying methods affect the physicochemical and quality characteristics of soybean curd residue, which could be important factors in the manufacture of processed foods.

        Insects are attracting the attention of alternative sources of protein. In order to produce high quality insects, studieson the development of safe and nutritious feed sources are needed. Given the cost of rearing insects, agricultural andindustrial by-products were good materials of insect feed. In the current study, Citrus unshiu peel (CP), soybean curdcake (SCC), soybean oil meal (SOM), and brewers dried grain (BDG) were investigated for their effects on larval growthand development of Protaetia brevitarsis. Interestingly, larvae fed on 10% SCC increased their weight by 3.5 times. Forthe larval period, they were significantly shorter than the control. Furthermore, minerals and amino acids were recordedto be high in them. The heavy metals were not detected in any of the investigated groups. These findings provided ascientific basis for the utilization of soybean curd cake as a nutritional feed source to promote larval growth and producequality insects.

        This study investigated the Texture Profile Analysis and Sensory characteristics analysis of 6 different Pork Meat-substituted Soybean Curd (PMSC) products with different gluten-fiber (GF) contentst. PMSC types were PMSC-GF 5%, PMSC-GF 10%, PMSC-GF 15%, PMSC-GF 20%, PMSC-GF 25%, and PMSC-GF 30%. The lightness (ΔL value) of cooked PMSC was decreased, whereas the redness (Δa value) and yellowness (Δb value) of cooked PMSC was not changed. Texturometer (TA XT Plus, England) was used for objective test and hardness, springiness, cohesiveness and chewiness of sensory characteristics were measured. PMSC with GF 5% to 15% were characterized high hardness score but PMSC with GF 20% to 30% were not significantly different. PMSC-GF 30% was the highest score in springiness and PMSC-GF 5% was the lowest. PMSC-GF 25% and 30% were high cohesiveness score but was not significantly different (p<0.05). Fourteen sensory descriptors were developed to evaluate the sensory characteristics of PMSC. The sensory characteristics of PMSC were sweetness, saltiness, springiness, hardness, chewiness, meat flavor, odor, loose particle and so on. Six different PMSC showed no significant difference in the attributes of loose particle. But PMSC-GF 5% and PMSC-GF 10% showed significant difference in the attributes of hardness. PMSC-GF 25% and PMSC-GF 30% showed no significant difference in the attributes of hardness. PMSC-GF 30% was the highest springiness score and PMSC-GF 5%, PMSC-GF 10% and PMSC-GF 15% showed no significant difference in the attributes of springiness. Overall consumer acceptance was surveyed. PMSC-GF 5%, PMSC-GF 10% and PMSC-GF 15% showed no significant difference in the attributes of color. PMSC-GF 25% and PMSC-GF 30% was the highest in the attributes of springiness and high moistureness, taste acceptance and overall acceptance. PMSC-GF 5%, PMSC-GF 10% and PMSC-GF 15% showed no significant difference in overall consumer preference but PMSC-GF 25% and PMSCGF 30% showed significant difference. Consequently it is indicated that texture of cooked PMSC-GF 25% and PMSC-GF 30% is very important sensory characteristics.

        The physical properties of jellified soybean curd residue (Biji) with the addition of various gums were investigated to optimize the direct availability of a by-product of the tofu production process. The lightness (L value) of the jellified Biji prepared with various gums was approximately 77~80, regardless of the concentration of gum used. Especially at the concentration of 0.1% and 0.3%, a pectin showed a significantly higher value compared with other gelling agents (carrageenan and agar). The strength of samples prepared on the basis of carrageenan showed the value of 335~569 g/㎠ and 234~335 g/㎠ according to the addition of locust bean gum and xanthan gum, respectively. On the other hand, the samples made with pectin and agar were 134~272 g/㎠ and 50~215 g/㎠, respectively. Where locust bean gum was used as a viscous agent, the adhesiveness of sample prepared by adding carrageenan was greater than those made with pectin or agar. The values were -6.0~-11.0 g, -2.7~-10.2 g and -3.7~-7.0 g, respectively. Overall, the strength and adhesiveness of samples according to increase of the added amount of Biji showed constantly increasing trend regardless of the type of gelling agent used. In the sample containing carrageenan this trend was most noticeable.

        This study was conducted to investigate the effects of different levels of soybean curd residue as an ingredient of TMR on growth performance and carcass characteristics of Holstein steers. Twenty four Holstein steers of 7 months age(average body weight 274.6 kg) were randomly allocated to 3 experimental groups, which contained 8animals per group during 15-months feeding trial. The treatments composed of the group fed concentrate and rice straw separately (Control), the group fed TMR containing low levels of soybean curd (T1), the group fed TMR containing high levels of soybean curd residue (T2). Body weight and average daily gain were not significantly different among the treatment groups during the feeding trial periods. Feed intake was not differ among treatment groups, but feed conversion ratio was significantly higher in T2 group compared to T1 group during late fattening stage (p<0.05). However, it was not different in overall average. According to the yield traits, carcass weight of control, T1 and T2 were 466.4, 451.1 and 460.1 kg, respectively. Back fat thickness, rib eye area and yield index were not different among the groups. The marbling score, meat color, texture and maturity in quality traits were not different among the treatment groups, but fat color was significantly higher in T2 group compared to T1 group (p<0.05). The quality grade (1+:1:2:3, NO.) tended to be higher for T1(0:2:1:5) and T2 (0:1:4:3) compared with the control (0:0:3:5). Therefore, these results indicated that TMR with soybean curd residue may be appropriate the growth performance and carcass characteristics of Holstein steers.

        To investigate of the recognition and using behavior on the Tofu, 46.3% of male and 53.7% of female adults in Daegu and Kyungbuk area were surveyed. The main results are as follows : 96.4% of the participants usually preferred the Tofu owing to health and about 68.4% of them had purchased Tofu made of domestic soybean. In addition, the responses to 7 questions about the Tofu were also measured on 5 point Likert scale. The item "Tofu is healthy food" and "Tofu is digestive food" were totally received the high point but "Tofu prevents osteoporosis" earned the lowest. Female had generally better knowledge of Tofu than the counterparts. Most participants relatively knew and had eaten common Tofu, soft bean curd, uncurdled bean curd, fried bean curd against functional Tofu such as Tofu added with omija, surimi, spinach, etc. But they intended to eat functional Tofu such as Tofu added with green tea, black sesame, spinach, omija. Furthermore, 60.7% replied "increasing" prospects for the Tofu consumption. 40.0% of adults said the plan should be "Make of good quality domestic soybean" for the purpose of better improvement to consume.

        대황(Rhubarb)은 중국과 일본에서 혈액 순환제, 진통제, 신장치료제 등으로 전통적으로 사용되고 있는 약용식물이다. 이 연구에서는 한국산 R. undulatum L.의 뿌리 추출물, 미국산 R. rhabarbarum L.과 중국산 R. palmatum L.의 줄기 추출물의 두부 부패에 관여하는 미생물에 대한 항균 활성을 평가하였다. Rhubarb의 최적 추출을 위해서 각각 50%, 70%, 80% 에탄올을 용매로 사용하였으며, 항균 활성은 Kirby-Bauert test, minimum inhibitory concentration (MIC)과 minimum bactericide concentration (MBC)에 의해서 평가되었다. Kirby-Bauert test 결과, R. undulatum L.의 뿌리 추출물은 대부분 두부 부패균에 대해서 항균 활성을 가지는 것으로 나타났으며, R. rhabarbarum L.의 줄기 추출물의 경우는 20μg/disc의 농도에서는 항균 활성이 거의 나타나질 않았으나, 고농도로 갈수록 높은 항균 활성을 나타내었다. 또한 R. palmatum L.의 줄기 추출물은 고농도로 갈수록 항균 활성이 높아졌으나, Pseudomonas aeruginosa에 관해서는 항균 활성이 나타나지 않았다. MIC와 MBC에 의한 항균 활성 평가실험에서는, 세 종류의 rhubarb 추출물 중에서 phenolic 화합물이 가장 많이 함유되어 있는 R. undulatum L.의 뿌리 추출물보다 R. rhabarbarum L.의 줄기 추출물이 MIC와 MBC 값이 낮았다. 이는 phenolic 화합물의 양 이외에 낮은 pH가 항균 활성에 영향을 준 것으로 판단된다. 본 연구를 통해서 rhubarb 추출물은 두부 부패에 관여하는 미생물에 대해서 항균 활성을 가지는 것으로 나타났으며, 천연 항균제로써 식품에 적용 가능성이 있는 것으로 평가되었다.
