What happens when you combine milk and Kiwi?

When you combine milk and kiwi, the enzymes in kiwi, particularly actinidin, can cause the milk proteins to curdle. This reaction may lead to a lumpy texture and an unpleasant taste, making it less desirable for consumption. For this reason, it's generally not recommended to mix fresh kiwi with milk in recipes. However, cooked kiwi or kiwi puree can be used in smoothies or desserts without causing curdling.
