Raw milk curdling in microwave
Why is it that every time I try to heat raw milk in a microwave it curdles and becomes like ricotta after a few seconds?
Best Answer
The problem you are facing is that your microwave temperature is too high and boils your milk too rapidly. The microwave does not heat food evenly and boils the milk too fast. Milk shouldn't be boiled too rapidly and doing this causes the casein in it to clump together and that curdles the milk. It should instead be brought 'to a boil' by heating on a slow heat for longer until it starts to boil.
So, you can try a couple of different options:
You can bring the milk to a boil in a pan on a stove on slow heat, which will take long depending on the amount of milk. And I can vouch for this method. I've seen my dad do this for years and as long as your pan is clean and the heat is low, you'll have a successful result.
I haven't tried this myself, but you can
Pour milk into a microwave-safe container and microwave on medium-high (70%) power, stirring every 15 seconds, just until steam begins to rise from the milk. To scald milk for custards or yogurt, heat 250 mL (1 cup) on HIGH for 2 to 2 1/2 minutes.- Reference

Heat lowers the pH of milk and makes it separate. This is why when you heat milk, there is a greater chance of splitting. It speeds up the souring process. The milk proteins may coagulate and separate from the water. The proteins are the solid clumps in curdled milk.Can you microwave raw milk?
Raw milk can also be pasteurized in a microwave oven. Heat to 165\xb0F. using a thermometer or temperature probe. Stir the milk once or twice during the heating period to equalize the temperature throughout.How do you heat up milk without curdling in the microwave?
In the microwave The microwave method: Pour milk into a microwave-safe container and microwave on medium-high (70%) power, stirring every 15 seconds, just until steam begins to rise from the milk. To scald milk for custards or yogurt, heat 250 mL (1 cup) on high for 2 to 2 \xbd minutes.Why is my fresh milk curdling?
This is what happens when milk curdles. When pH levels drop in milk, it turns acidic and milk protein (casein and others) molecules attract one another to form "curdles" or lumps. These lumps then float on the surface of the solution. The lumps are formed faster at warmer temperatures.How to Boil Milk in Microwave without Spillage | Heat Milk in Microwave | Boiling Milk in Microwave

Answer 2
I have the same issue and it is NOT because the milk has approached the expiration date when it's a day old or too high of a microwave setting when it dues thus randomly. What I've found is that it may be a chemical reaction with the rinsing agent in your dishwasher and milk.
Answer 3
As other answer says, you need to lower down power of your microwave. But if the minimal power is still to high (it can happen if you trying to heat very small amount of milk) use the lifehack: additionally put a glass of water into the microwave, it will absorb sufficient part of power.
Answer 4
Check the temperature/heat rating that you are setting on the microwave. Very likely its a bit too high and that's the reason why it has a similar reaction as to when lemon juice or vinegar is added to milk.
