The aim of this study was to review Byung-Kwa-Ryu recipes in old cookbooks of the head & noble family (Jong-Ga). As for details and classification, we examined the materials and recipes of Byung-Kwa-Ryu. To accomplish this, old cookbooks of the head & noble family ("Soowoonjabbang", "Eumsikdimibang", "Onjubub", and "Jusiksiui") were reviewed. The introduced Byung-Kwa-Ryu recipes numbered 47 total; four from "Soowoonjabbang", 18 from "Eumsikdimibang", nine from "Onjubub", and 16 from "Jusiksiui". We classified the foods (Byung-Kwa_Ryu) into two categories, Tteok-Ryu (Korean rice cake) and Kwa-Jung-Ryu (Korean traditional cookie), on the basis of previous studies. These were further classified into 11 categories: Tteok-Ryu (Jjin-tteok, Salmeun-tteok, Chin-tteok, Jijin-tteok), Kwa-Jung-Ryu (Yumilkwa, Yukwa, Jeongkwa, Dasik, Kwapyun, Dang (Yeot), and others. The most common Byung-Kwa-Ryu type was Jjin-tteok in Tteok-Ryu (14). The next most common Byung-Kwa-Ryu types were Yukwa in Kwa-Jung-Ryu (6) and Yumilkwa in Kwa-Jung-Ryu (5).

To meet the demand for high quality of foods with the expanded implementation of foodservice into kindergarten, and to make the efficient use of resources, the necessity of introducing central production unit with cook/chill system into kindergarten foodservice is getting increased. The purpose of this study were to develop standardized recipe applicable to cook/chill system for kindergarten foodservice and to evaluate the microbial and sensory quality. For quantitty production of cook/chill system in kindergarten foodservice, Korean traditional starch foods were selected as menu items. The followings are summary of the results： 1. Standard recipes to produce Various Boiled Rice (Boriebap and Yackbap) and Rice Cake (Chapsal-pat-sirutuk) for cook/chill system have been developed. 2. The microbial quality of Boribap, Yackbap and Chapsal-pat-sirutuk during 10 days chilled storage was very excellent. And in this experiment, the stability of storage of standard recipes of Boribap, Yackbap and Chapsal-pat-sirutuk at cook/chill system was proved for 10 days. 3. In the result of sensory evaluation, apperance of Boribap was decreased significantly on the third day of storage (p<0.005). The rest of the item of sensory evaluation of Boribap has no significance between the first day and the third day of storage. The tenderness (p＜0.05) and gelatinousness (p<0.005) of Yackbap had been rated high significantly in the third day of storage than the first day of storage. The rest of the item of sensory evaluation of Boribap has no significance between the first day and the third day of storage. The color and chewiness of Chapsal-pat-sirutuk was decreased significantly on the third day of storage (p＜0.05). The rest of the item of sensory evaluation of Chapsal-pat-sirutuk has no significance between the first day and the third day of storage.

A computer-assisted microbiological quality assurance program was developed based on HACCP data obtained from a 500 bed general hospital by assessing time and temperature conditions and microbiological qualities of six categories of menu items according to the process of food product flow. The purpose of the study was to develop a computer-assisted microbiological quality assurance program in order to simplify the assessment procedures and to provide a maximum assurance to foodservice personnel and the public. A 16-Bit personnel computer compatible with IBM-PC/AT was used. The data base files and processing programs were created using dBASE III plus packages. The contents of the computerized system are summarized as knows: 1. When the input program for hazard analysis runs, a series of questions are asked to determine hazards and assess their severity and risks. Critical control points and monitoring methods for CCPs are identified and saved in Master file. 2. Output and search programs for hazard analysis are composed of 6 categories of recipe data file list, code identification list, and HACCP identification of the specific menu item. 3. When the user selects a specific category of recipe from 6 categories presented on the screen and runs data file list, a series of menu item list, CCP list, monitoring methods list are generated. When the code search program runs, menu names, ingredients, amounts and a series of codes are generated. 4. When the user types in a menu item and an identification code, critical control points and monitoring methods are generated for each menu item.

Thai Jasmine rice (Oryza sativa, long grain Indica var.) is popular in southeastern Asia and China due to its non-glutinous, fluffy texture and fragrant smell. However it has a high starch digestibility, which leads to an increased glycemic index (GI). Therefore it may require modified cooking methods for diabetes patients. The objectives of this study were to optimize the ratio of Thai Jasmine rice, sea tangle, and olive oil (CLTR) based on consumers' acceptance. The GI of plain cooked Thai Jasmine rice (CLR) was measured as a control. Sensory evaluation and response surface methodology were used to determine the optimal ratio. Texture analysis and nutritional evaluation were also performed on the optimal recipe of cooked Jasmine rice with sea tangle. A multiple regression equation was developed in quadratic canonical polynomial models. We used 26 trained Chinese panelists in their forties to rate color, flavor, adhesiveness, and glossiness, which we determined were highly correlated with overall acceptability. The optimal CLTR formula was 34.8% rice, 2.8% sea tangle, 61.9% water, and 0.5% olive oil. Compared to CLR, CLTR had a lower hardness, but a higher springiness and cohesiveness. However, CLR and CLTR had the same adhesiveness and chewiness. The addition of sea tangle and olive oil delayed retro-gradation of starch in CLTR and increased total dietary fiber, and protein and ash contents. The degree of gelatinization, and in vitro protein and starch digestibility of CLTR were lower than those of CLR. Based on Wolver' method, the GI of CLTR (52.9, incremental area under the glycemic-response curve, ignoring the area below fasting, as used for calculating the GI [Inc]) was lower compared with that of CLR (70.94, Inc), which indicates that CLTR is effective in decreasing and stabilizing blood glucose level, owing to its lower degree of gelatinization and starch digestibility. Our results show that CLTR can contribute to the development of a healthier meal for families and the fast food industry.

천일염을 사용한 김치를 소재로 한 음료의 레시피를 개발하고자 하였다. 천일염으로 만든 김치를 첨가하여 제조한 음료에 대하여 감미료의 선호도는 올리고당 > 벌꿀 > 슈가파우더 > 설탕 > 아스파탐 > 배즙 순으로 나타났다. 관능검사로는 김치첨가음료의 색, 냄새 및 종합적 기호도의 3가지 항목으로 평가하였다. 종합적인 기호도 (Overall acceptance)측면에서 동치미 음료가 6.24점, 백김치음료가 6.00점, 배추김치음료가 5.76점 순으로 나타나 동치미음료가 백김치나 배추김치음료보다 더 좋은 관능검사 점수를 나타내었다. 천일염 김치 첨가량은 10%가 대조구와 차이가 없는 것으로 나타났으며 동치미 음료, 백김치음료, 배추김치음료 세 가지 모두에서 공통적으로 가장 적절한 것으로 조사되었다. 제조 후 상온에서 저장했을 경우 저장 시간의 경과에 따라 백김치나 동치미 음료, 배추김치음료 모두 각 관능검사 항목에 대한 관능평점은 저하되었다.

Silicon wafer etching in micro electro mechanical systems (MEMS) fabrication is challenging to form 3-D structures. Well known Si-wet etch of silicon employs potassium hydroxide (KOH), tetramethylammonium hydroxide (TMAH) and sodium hydroxide (NaOH). However, the existing silicon wet etching process has a fatal disadvantage that etching of the back side of the wafer is hard to avoid. In this study, a wet etching bath for 150 mm wafers was designed to prevent back-side etching of silicon wafer, and we demonstrated the optimized process recipe to have anisotropic wet etching of silicon wafer without any damage on the backside. We also presented the design of wet bath for 300 mm wafer processing as a promising process development.
