Physical Characterization of Cheese Curd with Different Rennet Enzyme Concentrations

Main Article Content

Abstract

The reliance on synthetic or imported food processing agents has


encouraged the exploration of optimized local cheese production.


Rennet is a critical coagulant used to separate casein from whey during


the formation of curd. This study aimed to evaluate the effect of


rennet concentration on the physical properties of cheese, specifically


focusing on coagulation time, yield, and curd firmness. Cheese was


prepared using pasteurized milk at 25-35oC with varying


concentrations of liquid rennet. The results showed that increasing


rennet concentration significantly accelerated the coagulation process.


However, excessively high concentrations led to a rubbery texture and


potential bitterness in the final product. Overall, this study


demonstrates that optimizing rennet dosage is essential for achieving a


balance between production efficiency and ideal textural


characteristics.
