Stretchable processed cheese and preparation method thereof

The invention provides stretchable processed cheese and a preparation method thereof. The processed cheese comprises the following raw materials in percentage by mass: 25%-70% of natural cheese, 13%-16% of chymosin casein, 10%-20% of butter, 0.25%-1% of modified starch and 1.0%-1.2% of emulsifying salt. The invention also provides a preparation method of the reprocessed cheese, the reprocessed cheese prepared by the preparation method can be vertically stretched to exceed 270mm in a molten state, the stretching length can reach 40cm in an application test, the wiredrawing effect attenuation does not exceed 30% in a shelf life, and the reprocessed cheese has a very good stretching characteristic. 本发明提供了一种可拉伸再制干酪及其制备方法。按质量百分比计算，该再制干酪的原料组成包括：天然干酪25％-70％、凝乳酶酪蛋白13％-16％、黄油10％-20％、变性淀粉0.25％-1％、乳化盐1.0％-1.2％。本发明还提供了上述再制干酪的制备方法，由该制备方法制得的再制干酪在熔融状态下可垂直拉伸超过270mm，应用测试中拉伸长度可达到40cm，且保质期内拉丝效果衰减未超过30％，具有非常良好的拉伸特性。
