The quality characteristics and their changes during storage of tofu added with pigmented rice powder were studied. As the addition of pigmented rice powder increased, the whey decreased but the yield increased. Textural characteristics of tofu added with pigmented rice powder did not significantly change but with the addition of pigmented rice powder increased, the hardness, gumminess and brittleness mostly decreased. During the initial time of storage, the pH of the tofu with pigmented rice powder decrease, but it in­creased again after eight days of storage. The pH of soaking solution of tofu decrease, but increased after six days of storage. The L, a and b values mostly increased during storage. As the addition of pigmented rice powder increased, the L, and b values decrease but a value increased. In sensory evaluation, the control tofu was evaluated better than samples added with pigmented rice powder in overall acceptability.

Whey is the soluble portion of milk that is removed after the setting of the curd in cheese manufacture. In industry, whey is widely used after processed to whey protein concentrates (WPC). There are many factors to decide the functionality of commercial WPC including its composition, solubility and physicochemical properties. Besides, drying methods can affect the functionality of WPC. In this research, whey protein concentrates were produced and dried in two different methods to investigate the effect of drying methods on the functionality of WPC. The solubility showed significant difference between samples depending on concentrations and drying method of whey proteins. Particle size of 10% WPC suspension was significantly bigger in freeze dried samples than in spray dried sample. However, Foam overrun did not show significant difference between samples depending on drying methods. Therefore, type of drying is important in some application and drying methods should be chosen by the functionality expected in WPC.

Purpose: This study was conducted to develop cooking program for children at community center. Methods: This study consisted of three parts. Part I involved determining the demand for a cooking program by educators (dietitians). In parts II and III the cooking program was developed and applied, respectively. A survey was carried out on 66 educators (dietitians) using self-administered questionnaire. Questions were based on current status and requirements of cooking programs. Cooking recipes and videos were focused on easily applicated, using common food ingredients, and safe for children. After application of the cooking education, program satisfaction was investigated. Results: Educators (dietitians) stated they needed a well constructed educational program, educational tools, and teaching manuals for children. In accord with survey results, three cooking recipes and videos were developed for children and recipe illustration cards were produced. Menus were ‘baby gimbap with a perilla leaf’, ‘steamed egg with tofu and scallions’, and ‘a bowl of rice with bean sprouts and egg’. Educators’ satisfaction scores for the developed cooking program after it has been applied at 12 community centers were very high. Conclusion: A various and practical cooking education program should be developed for children at community centers.

In many countries, recycling coal ashes as backfill materials for subsided lands, abandoned mine tunnels, and road pipeline constructions by making low-strength concretes with minimal amounts of cement is frequently considered for massive treatment of coal ashes. This study investigates the variation of heavy metals in the concrete test pieces prepared for the cases of using only Portland cement as binding material, fly ash as a replacement of the cement, sand as aggregates, and disposed ashes in the ash ponds as a replacement of aggregates. Heavy metal contents were measured based on the aqua regia extraction technique following the Korean Standard for Fair Testing of Soil Contamination and the influences of each materials on the total heavy metal contents were also assessed. Results show that the cement has the highest Cu, Pb, and Zn concentrations than any other materials. Therefore, the test pieces show significant concentration decreases for those metals when the cement was replaced by fly ash. Ponded ash shows low concentrations relative to fly ash in most of the parameters but shows higher Cu and Ni, and lower Pb levels than the sand aggregate. In overall, heavy metal levels of the test pieces are regulated by mixing among the used materials. Test pieces prepared during this study always show concentrations much lower than the Worrisome Level of Soil Contamination (Area 1), which was designated by the Soil Environment Conservation Act of Korea. 많은 나라에서는 화력발전소 석탄연소 잔재물로 생산되는 석탄재를 소량의 시멘트와 혼합, 저강도 콘크리트를 만들어 지반함몰지, 폐갱도, 도로관거 뒷채움재 등으로 재활용하는 방안이 석탄재의 대규모 처리방안으로 자주 검토된다. 본 연구에서는 석탄재로 저강도콘크리트를 만들어 콘크리트 내 중금속함량 변화를 고찰하였다. 이를 위하여 시멘트만을 사용하는 경우와 시멘트의 반을 비산재로 대체하는 경우, 모래를 골재로 사용하는 경우, 그리고 회처리장의 매립재로 모래골재를 대체하는 경우에 대한 콘크리트 공시체를 제작하여 중금속농도 변화를 고찰하였다. 중금속 함량은 토양오염공정시험기준에 따라 이루어졌으며, 중금속함량에 가장 큰 영향을 주는 재료들도 평가하였다. 연구결과, 시멘트는 다른 어떤 재료들 보다 Cu, Pb, Zn에서 현격히 높은 중금속농도를 보였다. 이로 인하여 시멘트를 비산재로 대체할 경우 중금속 농도는 뚜렷이 낮아지는 경향을 보였다. 매립재는 전체적으로 비산재에 비하여 낮은 중금속농도를 보였지만, 모래보다는 높은 Cu 및 Ni농도와 낮은 Pb농도를 보였다. 전체적으로는 콘크리트 내 중금속농도는 각 재료의 혼합에 의하여 결정되는 양상을 보였다. 본 연구에서 제작된 공시체는 모든 조사된 항목에 있어 토양환경보전법이 정한 토양오염우려기준(1지역)보다 현격히 낮은 농도를 보였다.

분쇄방법에 따른 석탄재 재활용 콘크리트의 중금속 분석결과 및 용출특성 변화

콘크리트는 덩어리이기 때문에 분석을 위해서는 분쇄를 할 수밖에 없다. 그러나, 콘크리트와 같이 여러 재료의 혼합물을 파쇄, 특정 입도를 선별하는 것에 따른 효과는 아직까지 적절하게 평가된 바가 없다. 본 연구에서는 시멘트와 비산재를 고화제로 사용하고, 매립재와 모래는 골재로 사용하여 콘크리트 공시체를 제작한 다음, 토양오염공정시험기준과 폐기물공정시험기준에 따라 중금속분석을 수행하였다. 이를 위하여, 먼저, 공시체를 어느 정도 파쇄한 다음 채질하여 <0.15 mm, 0.15~0.5 mm, 0.5~5 mm를 선별(분쇄방법 1)하여 분석하였다. 토양오염공정시험기준 분석 결과, 작은 입도의 시료가 높은 중금속 농도를 보이는 경향이 뚜렷하였다. 특히, <0.15 mm는 각 개별재료의 농도와 배합비로 계산된 이론값보다도 몇 배 높은 값을 보이기도 하였다. 반면, 시료 전체가 <0.15 mm를 갖도록 완전히 분쇄(분쇄 방법 2)하여 분석한 결과는 이론값과 비슷한 농도를 보였다. 이 같은 결과는, 부분 분쇄 시에는 작은 입도에 중금속 농도가 높은 시멘트와 비산재가 농집되는 것과 관련이 있다. 반면, 폐기물공정시험기준 분석에서는 모든 항목에서 매우 낮은 용출 농도를 보였고, 토양오염공정시험기준에서와 같은 경향도 관찰되지 않았다. Since concrete is a hardened aggregates of various materials, it needs to be crushed for chemical analyses. However, the effect of sample crushing on the analytical results has not been precisely assessed till today. In this study, we prepared concrete test pieces using Portand cements and fly ashes as binding materials, and ponded ashes and sands as aggregates and analyzed the heavy metals of the test pieces using Standards for Fair Testing of Soil Contamination (SFTSC) and Wastes (SFTW). For this, each test piece was partially crushed at first and sieved for separation of grains of <0.15 mm, 0.15-0.5 mm, and 0.5-5 mm from the same crushed samples (Crushing Method I). Results of those samples using SFTSC showed a clear trend that analyzed heavy metal concentrations are higher in the finer fractions. Particularly, fractions with <0.15 mm indicated much higher concentrations than the theoretical ones, which were calculated based on the concentrations of individual materials and their mixing fractions. In contrast, the analytical results were generally comparable with the theoretical ones when the test pieces were totally pulverized such that all the crushed grains were <0.15 mm in size (Crushing Method II). These results are associated with the fact that cement materials and fly ashes, which are high in heavy metals relative to other materials, are enriched in the fine fractions. The analytical results using the SFTW derived very low concentrations in most of parameters and did not indicate the dependence of concentrations on the crushing methods due to using distilled water as leaching agent.
