Background Information
Often I make homemade cheese using milk and rennet. When I first tried to make cheese at home, I failed making cheese several times because curd did not formed. However, when I usedhigh calcium milk, with higher calcium in it compared to ordinary milk, I succeed to get enough curd and therefore could make homemade cheese for the first time. This made me to guess that calcium has significant effect on milk coagulation process, and I became curious about the relationship between calcium content and milk coagulation process. Therefore, I conducted an experiment to investigate about how different calcium concentration affects clotting time of rennet while coagulating milk.
Enzyme is a protein, which acts as a biological catalyst by lowering activation energy for reactions, and therefore speeding up reactions.
