강근옥,이현자,차보숙 한국식품영양학회 1995 韓國食品營養學會誌 Vol.8 No.4

서울, 충청도 및 강원도 지역의 김장김치 담금방법을 알고자 203개 가정에서 설문조사를 한 결과 3지역에서 김장김치류중 배추김치는 95%이상 남았는데 배추선택시 결구도를 가장 중요시 하였다. 배추는 천일염을 주로 사용하여(66∼78%)소금물에 적신 후 다시 소금을 뿌려 약 7∼10시간 동안 절였다. 김치숙성시 서울과 충청도는 배추상태가, 강원도는 양념이 가장 큰 영향을 미치는 것으로 인식되었으며 김치보관은 70%이상이 김치 항아리를 이용하였는데 김치보관용기와 주거형태(단독 및 아파트)간에는 x^2=49.87(P<0.000)로 유의적인 관계가 있는 것으로 밝혀졌다. A survey study was carried out on the preparation methods of the Winter Kimchies in Seoul, Chung Cheong and Kang Won area by questioning 203 homes individually. The reaults showed that the cabbage Kimchi was prepared more than 95% of total Kimchi a good heads of the Chinese cabbage were selected as proper quality of the cabbage. The cabbage were brined for 7∼10 hours with using sun dried salts mostly(66∼78%). In Seoul and Chung Cheong area the quality of Chinese cabbage was regarded as the primary factor and the seasoning materials in Kang Won area for good quality of Kimchi, more than 70% of the residents prepared Kimchi in Kimchi jar, and the correlation between the jar use kind of resident such as house or apartment was significantly high(p<0.000).

The purposes of this study were to a) find out the operational characteristics of the contract-managed highschool foodservice in Seoul, b) investigate the expected level of meal-price and facilities investment cost perceived by contract-managed highschool foodservice managers c) compare the present level and expected level of meal-price and facilities investment cost. From October 12 to November 13 in 2001, the questionnaires were mailed to 249 high schools which was managed by contract foodservice company with respondent rate 40.2%. Data were analyzed using SPSS Win(10.0) for descriptive analysis and one group paired t-test. The results of this study were as follows ; 1. The student enrollment of highschools run by contract-managed foodservice was 1,243 with 72.6% participation rate of school lunch program. The average meal-price was 2,138 won. The average annual period of school foodservice operation was 156.78 days per year. The average contracting period was about 3 years. 2. The average cost concerned in the facilities investment amounts 169,578,180 won at the initial investment and 25,204,092 won at the repairs and maintenance cost in the course of operation. 3. The present level of meal-price and facilities investment cost were respectively 2,136won/meal and 171,157,336.72 won. And expected level.of meal-price and amount of facilities investment cost were 2,418.75 won and 121,353,215.19 won. Comparing the present level with expected level of the meal-price and facilities investment cost, expected level of meal-price was significantly higher than the present level of meal-price(p<.001) and expected level of facilities investment cost was significantly lower than present level of facilities investment cost(p<.001).

메밀 싹 추출물 에멀젼의 제조 및 에멀젼의 열 안정 특성

차보숙(Bo-Sook Cha) 한국식품영양과학회 2014 한국식품영양과학회지 Vol.43 No.10

메밀 성분 중 루틴의 추출 효율을 높이기 위해 메밀을 발아한 후 루틴 및 polyphenol 추출 효율이 높은 추출방법을 선택하였다. 메밀의 발아는 흙 재배가 효율적이었으며, 8일 후에는 polyphenol 함량이 10.66 mg/g으로 메밀 종자에 함유되어 있던 polyphenol 함량의 10배 이상 높은 양을 얻을 수 있었다. 발아 메밀에서 추출된 루틴을 포함한 polyphenol 성분은 에멀젼을 제조하여 열에 대한 안정성을 높이는데 효율이 있는지를 확인하였다. 에멀젼은 homo mixer만을 통과시키는 것보다 유압식 균질기를 통과시켰을 때 포접 효율이 높을 뿐만 아니라 열처리 온도에 대하여 열 안정성이 우수한 것을 알 수 있었다. This study analyzed the production and heat stability of an emulsion made from buckwheat sprout extracts with high rutin content. To obtain high rutin contents, buckwheat was sprouted and the polyphenols and rutin were extracted from buckwheat sprouts. Concentrated extracts were made into an emulsion using a homo mixer and hydraulic homogenizer, after which heat stability was analyzed. The polyphenol contents were highest in ground sprouts grown for 8 days (10.66 mg/g), which was 10 times higher than those of buckwheat seeds. Extraction with 50% ethanol after blanching was the most effective method for obtaining extracts with higher polyphenol content and rutin content. Extracts were concentrated up to 60% soluble solid content and then emulsified using a homo mixer and hydraulic homogenizer. Heat stability of the emulsion passed through the hydraulic homogenizer was slightly higher than that made using the homo mixer. The heat stability of the emulsion was more strongly affected by heating time than temperature. In conclusion, the buckwheat concentrate emulsion passed through the hydraulic homogenizer was more heat stable than buckwheat extract alone.

쌀가루의 액화와 호화에 의한 누룽지 분말 가공조건 연구

차보숙 한국조리과학회 1999 한국식품조리과학회지 Vol.15 No.5

숭늉 제조용 누룽지 가루의 제조방법을 개발하기 의하여 쌀가루을 액화시키고 호화시킨 다음 hot plate에서 태우는 방법을 조사하였다. 누룽지 가루는 태움정도에 따라 3가지로 구분하였다. 그 결과 액화를 더 할수록 쌀가루 분산액의 DE값이 증가하고 점도가 감소하였으며 이 현상은 액화 2분내에 현저하였다. 누룽지 가루로 숭늉을 80-100℃에서 추출하였을때 처음 10분간에 80% 이상의 총 고형분이 추출되었으며 추출온도가 높을수록 추출수율이 높았다. 숭늉의 침전된 고형분의 부피와 탁도는 추출온도와 시간이 길수록 높은 값을 보여주었다. 3가지 누룽지 가루중 가장 많이 태운 것이 숭늉의 고형분 수율과 탁도가 가장 높고 L값이 가장 낮았다. 또한 향미와 색에 대한 관능검사 결과는 가장 많이 태운 것이 가장 높은 점수를 보여 주었지만 중간정도 태운 누룽지 가루숭늉의 기호도가 가장 높은 결과를 보여주었다. An investigation was carried out to develope a processing method for Nooroong-gi powder for use of Soongneung extraction by hydrolysis with α-amylase and gelatinization of rice powder followed by toasting on hot plate. Three kinds of Nooroong-gi powder were prepared according to the degree of toasting. As the hydrolysis time increased, the DE value fastly increased during initial 2 minutes and viscosity decreased markedly. When the Soongneung was extracted from Nooroong-gi at 80-100℃, more than 80% of total solids was extracted during initial 10 minutes and higher temperature yielded more extraction solids. Sedimented volume of insoluble solids and turbidity were increased as the extraction temperature and time increased. Among the three Nooroong-gi powders, the more toasted one showed the higher yields, turbidity and lower L color values of Soongneung. Even though all sensory properties of the most toasted Soongneung were scored highest, the medium toasted one obtained the highest score in preference.

The purposes of the study were to identify the operational characteristics in employee feeding facilities, and to examine the correlations of productivity and these characteristics. A questionnaire was developed and mailed the 500 dietitians in employee feeding facilities in Seoul and Kyoungki Do. Usable questionnaires were received from 117 respondents for a response rate of 23.4%. The questionnaire was designed to determine the productivity index and to investigate the relationship between operational characteristics and productivity index. The questionnaire was contained 2 parts with a total of 16 statements. Data were analyzed for descriptive statistics and Pearson correlation analysis using SPSS/PC programs. The average productivity indices of 117 facilities were 6.91 meals/hr. Total meals served/week was significantly correlated to the productivity index (r=0.441, p < 0.001). No of average servings per meal, percentage of convenience food use, average minutes for service/day, and employment in professional practice of dietitian were also positively correlated, while food cost was negatively correlated to the productivity.
