This study was conducted to research the status, history and prospects of farm scale milk processing and to develop a management strategy for small scale milk process plant in Korea. Also it aims to provide ways to apply it so as to vitalize the farm made milk products market practically. This study was also treats the practical development of dairy farm school programs through the farm scale milk processing. Farm-scale milk plant (FMP) should be some of the ideas to develop small scale and using the resources according to the local features, limited expanding in regional market , produce by consumers order amounts, management policy will be transferred organic dairy farm. A few policy suggestions to put FMP system of financial support would not from beginner, it is better to settled FMP system by government or co-operation group in practical support programs were proposed. What the state needs to do through direct involvement were to put efforts at demand expansion on FMP system products, to certificate and safety the farm made milk products marketing system settings, to build more variation chance of the milk products. What was more important, however, was support policy, to create the network of FMP market and to develop of training program contents for each FMP operation unit. The ideal FMP model for the development of Dairy Farming proposed in this research will be applied as a relevant reference in managing and realizing environmental friendly and sustainable dairy industry at the national level.
原乳의 貯藏方法 및 溫度條件에 따른 細菌學的 乳質改善에 關한 硏究
裵仁烋 順天大學校 1983 論文集 Vol.2 No.1
本 試驗은 原乳의 저장방법 및 운송시의 온도조건에 따른 細菌學的 品質을 調査하기 위하여 遂行되었는데 그 結果를 要約하면 다음과 같다. 1. 여름철에 경기도 일원의 목장에서 냉각기가 설치된 목장원유의 일반세균수(SPC)는 法的許容値인 400萬/㎖ 이하가 51.5%였고, 냉각기가 未設置된 목장원유의 경우 400萬/㎖이하가 17.4%에 불과하였다. 2. 목장의 냉각기에 저장한 원유를 Tandklorry의 운송조건과 같이 냉장상태로 운반보관하여 시험한 경우 (가)와 일반 트럭의 수송조건과 상응한 室溫하에서 3시간 방치하여 시험한 경우(나)의 각 細菌數 변화는 다음과 같았다. ① 一般細菌數 : (가)의 경우 法的許容値인 400萬/㎖ 이하는 全檢體의 78.5%였고 (나)의 경우 43.6%로 나타났다. ② 大腸菌數 : (가)의 경우 10萬/㎖ 이하가 全檢體의 84.2%, (나)의 경우 10萬/㎖ 이하가 58.3%였는데 (나)의 경우 10萬/㎖ 이상이 41.7%나 되어 원유 품질 저하의 원인균으로 크게 작용하고 있음을 알 수 있었다. ③ 耐熟性菌數 : (가)의 경우 1萬/㎖ 이하가 全檢體의 80%였고 (나)의 경우 1萬/㎖ 이하가 46.7%였는데 (나)의 경우 10萬/㎖ 이상이 全檢體의 31.1%였다. ④ 低溫菌數 : (가)의 경우 乳製品의 品質에 영향을 주는 수준인 100萬/㎖ 이상은 1.5%였고 (나)의 경우 100萬/㎖ 이상이 38.3%였다. This study was carried out to investigate the bacteriological quality of raw milk by differencial storage methods and temperature condition in farm milk collected in Gyung-Ki area. The results obtained were as follows: 1. During the summer, in case of raw milk samples collected at the farms that operated the refrigeraoer, the ratio of samples that had bacterial less than the legal limit, 4.0× ?? /ml was 51.5%, and in case of raw milk samples of the farms that didn't operate a refrigerator, the ratio was 17.4%. 2. The number of bacteria was checked about two conditions of raw milk. (a) One was transported under the condition less than 5℃ like tanklorry transportation condition. (b) The other was put under the condition exposed at room-temperature about three hours. The method of (b)was chosen as that corresponding to the condition of ordinary truck transportaion. The variation of the number of SPC, coliform bacteria, thermoduric becteria and psychrotrophic bacteria was as follows: 1) SPC: The ratio of samples that had SPC less than the legal limit, 4.0× ?? /ml was 78.5% and 43.6% in condition (a) and condition (b) respectively. 2) Coliform bacteria : The ratio of samples that had coliform bacteria less than the number of 1.0× ?? /ml was 84.2% and 58.3% in condition (a) and (b), respectively. In case of condition (b) was found that coliform bacteria made a great influence on the deterioration of raw milk quality, because the ratio of samples that had coliform bacteria greater than the number of 1.0× ?? /ml was 41.7%. 3) Thermoduric bacteria : The ratio of samples that had thermoduric bacterial less the number of 1.0×10⁴/ml was 80% and 46.7% condition(a) and (b), respectively. And in case of condition (b) 31.1% was greater than the number of 1.0× ?? /ml. 4) Psychrotrophic bacteria : The ratio of samples that had psychrotrophic bacteria greater than the number of 1.0× ?? /ml which is the level giving an influence on the deterioration of dairy products quality, was 1.5% and 38.3% in condition (a) and (b).
