Studies on Cholesterol Free Mozzarella Cheese Manufacture

Cholesterol Free Mozzarella Cheese 제조에 관한 연구

Abstract

This research was aimed to manufacture the cholesterol free Mozzarella cheese with corn oil that contains high unsaturated fatty acid helping the reduction of serum cholesterol. Cheese stored at 1$0^{\circ}C$ was evaluated with general analysis, volatile free fatty acid, cholesterol, meltability, stretchability, color, rheological properties, and sensory evaluation. Moisture contents decreased during cheese storage period, whereas protein contents and pH value increased significantly (P < 0.05), but fat contents did not show any significant change. Linoleic acid was tile main volatile free fatty acid in a fat of cheese, and cholesterol contents were measured 4.34$\pm$ 0.04 mg/100 g in cheese. The meltability of cheese gradually increased during ripening, while the stretchability decreased. The color of cheese showed translucent yellow. Hardness, springiness, and cohesiveness increased significantly up to 21 days of storage. Compared to control cheese made by conventional way, QDA scores of shiny, oiling off, and melting of cholesterol free cheese were significantly different. These results suggested that health-oriented cholesterol free Mozzarella cheese would be made by addition of the corn oil.

혈중 콜레스테롤 농도를 저하시키는 건강지향적인 불포화 지방산을 다량 함유한 옥배유로 원료유 지방을 표준화하여 cholesterol free Mozzarella cheese제조 후 특성을 살펴 보았다. 치즈 제조용 원료유는 안정성이 있었고, 최종 시료인 치즈에서 휘발성 유리지방산은 콜레스테롤 상승에 영향을 미치는 palmitic acid가 일반 치즈인 대조구에서 가장 높게 측정된 반면에 실험구인 옥배유를 첨가하여 만든 치즈는 동맥경화 및 성인병 등의 예방, 치료에 도움을 주는 linoleic acid 조성 이 가장 높게 나타나 영양학적으로 우수한 결론이 돌출되었다. 포화지방산에 대한 불포화지방산의 비율은 대조구가 7:3, 옥배유를 첨가하여 만든 치즈가 2:8로 나타났으며, 콜레스테롤은 대조구의 43.58 mg/100 g에 비해 옥배유를 첨가하여 만든 치즈는4.34 mg/100g만 측정되어 건강에 유의한 결과가 나타났다. 결과적으로 본 연구는 혈중 콜레스테롤 저하효과를 나타내는 휘발성 유리지방산을 다량 함유하고, 콜레스테롤 함량이 대조구의 10%수준인 영양학적으로 우수한 건강지향적인 cholesterol free Mozzarella cheese를 제조할 수 있었다.
