摘要

本研究旨在确定使用木瓜蛋白酶作为凝固剂对牛奶油炸乳的物理和感官的影响。试验采用完全随机设计(CRD), 4个处理,4个重复。这些处理的木瓜蛋白酶测试水平包括:P1: 0.5%的牛奶体积,P2: 1%的牛奶体积,P3: 1.5%的牛奶体积和P4: 2%的牛奶体积。测量的变量包括凝乳产率、炸乳产率、密度、pH、颜色、味道、香气和质地。结果表明,该处理对炸乳产量、色、味、香均有显著影响(P0.05)。由此可见,增加木瓜蛋白酶水平可降低凝乳产量和密度,提高煎炸乳产量和pH值,使煎炸乳质地更加光滑,但对煎炸乳的色、味、香保持稳定。在木瓜蛋白酶用量达0.5% (P1)时发现效果最佳。

Characteristics of Fried Milk Made of Cows Milk by Using of Papain as a Coagulant
This research aims to determine the effect of the use of papain as a coagulant on physical and organoleptic of fried milk made of cows milk.  The Completely Randomized Design (CRD) with 4 treatments and 4 replication was applied in this experiment. Those treatment were papain levels tested consist: P1: 0.5% of milk volume, P2: 1% of milk volume, P3: 1.5% of milk volume and P4: 2% of milk volume. Variables measured were curd yield, fried milk yield, density, pH, color, taste, aroma and texture. The results showed that the treatment had a significant effect (P<0.05) on curd yield, density, pH and texture of fried milk and had no significant effect (P>0.05) on fried milk yield, color, taste and aroma. It can be concluded that increasing of papain level can decreased curd yield and density, increasing of  fried milk yield, pH and smoother in texture,but  stabilized in  color, taste and aroma of fried milk. The best results found at the use of papain as much as 0.5% (P1) .
