Milk boils out because -
Milk is a colloid that has many substances suspended in it such as protein, sugar and fat. When milk is heated slowly the proteins and fat get separated. Since protein and fat are light they rise to the surface of the milk and collect together in the form of cream.
Milk has a high content of water in it and when the milk is heated some of the water gets converted into vapor. Since the surface of the milk is covered by cream the vapor gets trapped below the cream layer.
As the milk is heated the trapped water vapor expands and pushes against the layer of cream. The cream layer is lifted up as the water vapor expands and finally the pressure of the water vapor bursts through the cream layer and when this happens milk boils over and spills out.
Water does not boil and spill out because -
When water boils, bubbles form at the surface of water and burst. For water bubbles to expand further the temperature must be high enough so that the vapor pressure exceeds the atmospheric pressure or else the water vapor bubbles shrink and vanish.
What to be made from stale milk?
If you want to try making cheese, use fresh milk, stale milk will likely have bacteria that will result in poor cheese.
Take a look at this website for step by step directions on making a simple cheese:

Why do milk turn sour in lightning?
No.
That's the standard answer. But we had a thunderstorm last night, and the milk we had left out on the kitchen worktop is cottage cheese this morning. It wasn't fresh, but would have lasted another day or two. Perhaps in the atmospheric conditions which produce thunder, milk goes off sooner than at other times.
Strawberries grow on a low creeping vine in the early summer in most places. The plants come back year after year and spread by rooting along the new vines that it grows every year. Strawberries are best when picked fresh off the vine and eaten right away!
Simple answer:
You take 10 oranges.
You squeeze their juice. Just like you'd do at home.
You put that juice on high heat to evaporate about 75% of it's water. (This doesn't make it loose nutritional value, except Vitamin C, in oranges case.)
You're left with a concentrate.
You then add SAME quantity of water that you evaporated, back to that concentrate.
Why would you do this?
Because transporting the concentrate across country is a lot less heavy, hence cheaper to transport.
Once the trucks arrive to the factories, they put the water back into the concentrate... and ship it to your local store.
IN OVERALL: Based on my research, reconstituted is NOT bad for you. It's still healthy for you. However, home made juice, squeezed with juicer, is A LOT more nutritious/healthier.
Only problem is: most people don't have time to squeeze juice from 10 oranges, nowadays.
Why is it a good thing to have pasteurised milk?
It kills most of the bacteria, extending shelf life and reducing bacteria to safe levels. This is more effectively accomplished by boiling, but this has both cost and taste repercussions making pasteurization a reasonable middle ground between killing off unwanted organisms and maintaining the taste and integrity of the milk.
Is pasteurized milk safer than uht milk?
The two should both be equally safe if processed properly and stored properly.
Pasteurisation is a process to kill pathogens and some spoilage organisms and extends shelflife to about 14 days.
UHT sterilisation kills all organisms in the product and extends shelflife to 6 - 9 months.
Is spoiled milk able to be drunk?
Drinking spoiled milk is a very unsafe practice since expired milk can be contaminated by dangerous bacteria which can make you very sick. Don't risk it, toss the milk if you have any doubt about whether it's still good and go get new milk.
When you add an acid (lime, vinegar, etc.) to normal milk, you get modern soured milk. Soured milk is NOT the same as spoiled milk. The question was regarding spoiled milk. Modern pasteurization kills the good bacteria that traditionally allowed normal milk to ferment into sour milk (called buttermilk because this was the run-off from the butter churning process.)
If you drink spoiled milk, you run the risk of food poisoning from unhealthy bacteria which may have found it. Fortunately, it is fairly easy to tell if milk has begun to spoil due to distinct changes in smell, texture, and flavor. Toss it.
Why Does rubber float on milk?
In order to float, the bubble hitches a ride on a gas that is slightly denser than the air trapped inside of it: carbon dioxide!
The LD50 (lethal dose for 50% of the population) for milk is not well-defined, as milk is generally considered safe for consumption and is not toxic. However, excessive consumption of milk can lead to gastrointestinal distress or other health issues in some individuals, particularly those who are lactose intolerant. In healthy individuals, the amount of milk required to reach a lethal dose would be impractically high and is not typically studied. Thus, milk does not have a standard LD50 value like many toxic substances do.
What instrument measures milk?
No single instrument; it's actually very expensive to do quality control and product testing.
You could test for fat concentration, but that could be fooled by adding other oils.
You could test for protein, but that could be fooled by adding proteins, or even just by adding chemicals that come up the same on the tests (there are many)
You could test density, but for the same reasons, this won't tell you either.
You could take the milk to a microscope and do a visual confirmation, but this would be very time consuming and random, and wouldn't pick up solutes.
You could test for poisons and other chemicals individually, but for each one you test, that's more time and money spent. Test for lead, test for every possible pesticide.
You could just feed a rat on it and see if the rat dies (the old method); but that will only tell you if it's extremely poisonous (might still kill a human without killing a rat).
What is the best whole milk to buy?
All different types of milk have pretty much the same amount of vitamins A and D, as well as calcium. All of them will provide what most people need for children's growth and strengthening of the bones. Younger children benefit from full milk
Can drink milk after eating fish?
I don't see any reason why it should be unhealthy. Unless you have an allergy or block your throat, preventing yourself from breathing
Common chocolate drinks are chocolate milk and hot chocolate. Chocolate milk is a mixture of milk, cocoa powder and sugar, served cold. Hot chocolate is either hot chocolate milk or solid chocolate melted in milk.
Vegetables do not produce literal milk like a cow. However there are products made from plants that resemble milk in both appearance and nutrition. Most prominent of these is soy milk, made from soy beans. Soy milk has nearly a 2000-year history since its appearance in Asia in 82 AD and it's nutritional content is very close to that of cow milk. It can also be coagulated to make tofu just like milk can be coagulated to make cheese. Other examples include rice milk, coconut milk, almond milk, and many more.
Does drinking milk help prevent dehydration?
NO. Cows milk will not dehydrate you, although the fat content in the milk will make the fluid slower to absorb. so if you need a quick rehydrating, drink water or.... in a recent study (British Journal of Nutrition Vol 98) Skim milk was shown to be easier to absorb due to several nutrients that increased absorbtion rate.
What happens to milk at the dairy?
Milk is passed through points so that any of the big impurities are sorted out. Then it is filled in tanks and is pasteurized in order to kill microorganisms and to make it pure . then it is either filled in respective storages for the sale.
How do you increase the butter fat in your cows milk?
You could try increasing milk fat content by increasing energy content of a dairy cow's ration, but the best way is via genetics: get some Jersey and/or Brown Swiss genetics in your herd to increase milk-fat in your cows.
What are the advantages of powdered milk?
The advantage of powdered milk is that it has a longer shelf life than fluid milk and you can portion it out as needed.
When do babies gray wolves stop drinking their mother's milk?
Foals stop drinking their mothers milk around six months old.
