The milk of what animaldoes not curdle?
A
Correct answer
Explanation
Human milk has a unique protein composition with a whey-to-casein ratio of approximately 60:40, which is significantly different from cow's milk (20:80). The lower casein content and different protein structure prevent human milk from forming the solid curd that other animal milks produce. Cow, camel, and goat milks all curdle readily when exposed to rennet or acidic conditions like lemon juice.
