Milk is a high-protein drink. The protein will denature when it encounters acid, that is, it will condense into tofu. This is consistent with the principle of making milk tofu. However, milk should not be heated above 40 degrees, so it is not good to stew papaya with milk. It is okay to eat it as a flavor food occasionally, but it is defective from a nutritional point of view. It shouldn't be spoiled. It reacts with the substances in papaya. Milk cannot be heated too much as it will destroy the nutrients. Correct method: Peel and cut papaya into pieces. Put it into a juicer, add an appropriate amount of fresh milk, sugar, and ice cream, and mix at medium speed for a few minutes. Drink it on the spot. If it needs to be stored, do not leave it for more than 30 minutes (winter) and 20 minutes (summer) to ensure the best flavor.
