Abstract

This study was conducted to investigate the amount of fat, vitamins and minerals in milk can be affected by hydrodynamic cavitation since cavitation is recently focused on as one of the sterilization methods. Vitamins (vitamin A, $B_2$), minerals (Ca, P, Mg, Zn) and fat contents were measured according to Ministry of Food and Drug Safety's Processing Standards and Component Specifications of Animal Product. Vitamin A & $B_2$ contents decreased approximately 23% & 19%, respectively after cavitation. Minerals content showed no change after cavitation. Also, P and Mg contents were reduced after cavitation to 2 mg/100g and 0.1 mg/100g, showing no change. Milk fat content was 3.46% before cavitation and 3.41% after cavitation, displaying no difference. Hydrodynamic cavitation process displays a possibility to replace existing pasteurizing method, as it does not change vitamin or mineral contents in milk. Therefore, a more clear and systematic research on hydrodynamic cavitation pasteurization is needed to distribute excellent quality milk and to emphasize physiochemical properties and quality change of existing heat pasteurization process.

본 연구는 멸균 방법 중 하나인 수력학적 공동현상을 이용한 살균처리로 인한 우유의 비타민, 무기질 및 지방 함량에 대한 영향을 조사하고자 한다. 비타민(vitamin A, vitamin $B_2$),무기질(Ca, P, Mg, Zn) 및 조지방 함량을 식품의약품안전처의 축산물 가공기준 및 성분규격 실험법에 따라 측정하였다. Vitamin A는 처리 후 약 23% 감소하였고, vitamin $B_2$는 약 19% 감소하였다. 무기질의 경우, 처리 전후의 함량 차이가 거의 보이지 않았다. 또한 P는 2 mg/100g, Mg은 0.1 mg/100g의 함량 차이를 보였다. 우유의 조지방 함량은 처리 전 3.46%, 처리 후 3.41%로 차이가 거의 나타나지 않았다. 수력학적 공동현상 처리 시 우유의 비타민과 무기질 함량을 변화시키지 않아 기존 살균 방법을 대체할 수 있는 가능성을 보여주었다. 따라서 기존 가열 살균처리 시 발생하는 이화학적 특성 및 품질의 변화를 강조하고, 우수한 품질의 우유를 공급하기 위하여 수력학적 공동현상 살균처리에 대한 명확하고 체계적인 연구가 더 이루어져야할 것으로 보인다.
