When a cow is milked, and as the milk settles, a layer of cream forms at the top of the milk. This used to be the way people would judge the quality of milk. A thicker layer of cream meant better quality milk, and especially when milk was still normally sold in bottles, you could easily see into the bottle to judge the cream layer.
Pasteurization had become standardized for milk in most countries, since heating the milk destroys any bacteria in it, making the milk safer to drink. Homogenized milk was the next step. Pasteurized milk could still easily have milk fat proteins separate from the rest of the milk. For some people this was viewed as a disadvantage, though others argue homogenized milk doesn’t taste as good.
Since milk is an oil and water combination, it doesn’t stay mixed. Homogenized milk is run through tiny tubes, sometimes during the pasteurization process to keep fat and liquid molecules together. Fat molecules are reduced in size and tend to disperse more evenly throughout the milk so that creaming on the top of milk doesn’t occur. You can also use the homogenization process to reduce overall milkfat in milk. 2% milk is stripped of some of the fat molecules to produce lower fat milk
Homogenized milk also helps deal with a side effect of pasteurization. When milk is heated, the white cells and bacteria collect on the bottom of the milk, forming a thick, and many think, disagreeable layer. When milk has been fed thorough a small tube or orifice, this bottom layer gets mixed through the milk. The process of making homogenized milk, which gained the most popularity in the 1950s, has resulted in longer lasting milk, and the ability to ship milk greater distances.
Not everyone is pleased with homogenized milk, and sometimes you can look for unhomogenized versions. These still may be pasteurized, but many come in raw milk versions, which can prove unsafe to drink. Though it must be said that many people drink raw milk with no ill effects, there is occasional bacterial contamination of raw milk that poses a potential health risk.
On rare occasions you can find pasteurized but not homogenized milk. If you’re trying to whip cream, try to look for it at specialty stores, as it tends to whip much more quickly than does homogenized cream. You may find the occasional dairy that produces unhomogenized milk, but do remember this should not be treated in the same way as the homogenized liquid. First, you may want to give it a shake when you use it to break up the cream molecules. Second, it usually will expire more quickly, and may be more apt to absorb unpleasant tastes from your refrigerator.

What happens to "homogenized milk" when it is boiled? Does it get restored to pre-homogenized/natural state? |

In Southern California, Trader Joes sell non-homogenized milk labeled 'Cream Top.' It's so delicious, better than homogenized. And you can see the thick cream layered on the top. Scoop it out with a knife, add a little sugar and hmmmm-mmm! I always get Cream Top, it's thicker and tastes better. A little fattening though, just a little but worth it. |

I used to work weekends on a farm and discovered 'real' milk as well. Ever since then I only buy milk directly from farms. A previous commenter has mentioned trying to find a small holding and buying your milk directly from there and I have to agree. Commercialisation of the milk industry, while necessary to meet demand, has totally destroyed the taste. Milk now is effectively just a whitener for coffee and tea, which is a real shame. The milk I buy, direct from a local farm just north of Canberra, has taste that changes over the year. I can tell when the cows are eating new pasture grass, or hay, even if they are having to eat more protein/molasses (usually during winter). In short, it has flavour. When I'm drinking 'standardised' milk (i.e., coffee in a cafe) I can tell - it is tasteless and just makes the coffee white. |

I asked Stonyfield why they discontinued their wonderful plain whole milk yogurt, that had the cream settled on the top. They said, it was debated, and was a toss-up, so they decided to change it. (Why, if it was a toss-up?) I asked how they kept the cream from rising to the top. They said they homogenized it. I will not buy their yogurt anymore. |

@Críona: The globules found in non-homogenized milk are larger and more readily digested. When milk is homogenized, those globules are broken down into spheres small enough to pass directly through the walls of the stomach, into the blood stream. This creates small holes in the vessels and other surfaces. These holes are then patched by cholesterol. The only reason for breaking them down to this size is so that they'll stay suspended in the milk, instead of floating on top (cream on top). You can find this information in Healing with Whole Foods (pg. 19) by Paul Pitchford, with excellent in-text references. |

Before homogenization and pasteurization people drank milk raw, and there is no problem as long as the cow is clean and healthy. The reason for pasteurization in our foods is due to the disgusting state of our FDA regulated dairy farms. Drinking raw milk from a local farmer is perfectly safe if the conditions are clean and promote health and low stress among the cows. The problem becomes the mass production of a needless substance like milk in a small plot of land. Thousands of cows are set in tiny plots where they walk around in feces and are regularly given antibiotics until "X" amount of time before slaughter. All this is irrelevant however if the consumer becomes educated. Visit the actual farm where your buying milk from and see it for yourself. If they don't let you bring cameras onto the grounds then get a clue as to what is going on. Disease is caused by poor food choices made by a society of people who do not think for themselves. -Dan |

Homogenization breaks the cream break down so that your body cannot absorb it as the way nature intended and it ends up in your bloodstream because it is broken down--which does cause heart problems. The shelf life has to do with the temperature it is heated. For example, Hartzler's Dairy in Ohio (where I buy all of my milk) uses a low temperature vat pasteurization process and does not homogenize their milk. The Hartzler's heat their milk to 145 degrees in a vat for 30 minutes instead of heating it to more extreme temperatures of 160 for 15 seconds (HTST) or even higher to over 200 degrees for less than two seconds (UHT) and because they do it this way, the milk only has a shelf life of 18 days. But the health benefits are certainly worth it. Enzymes are protected and your body is able to digest the milk better because the milk is in a more natural state. |

"has resulted in longer lasting milk" That part isn't true. While the milk can travel farther without significant separation, breaking up the fat globules makes it easier for the fat molecules to combine with other things, making them turn rancid more quickly once the package of milk is opened. Milk that has not been homogenized will last longer after it has been opened, but the cream will separate, so it needs to be shaken. |

I think many species would consume other species' milk if or when they get a chance (but since they can't milk an animal or suckle their breasts,they eat them instead). i think only babies adopted by another species like we see on tv sometimes or things like cats given milk by human owner etc. are more possible. Many species also consume others' eggs. This is why mothers usually try to protect them. |

Why do people insist on eating the milk of other species? No other life forms do this. Milk is intended for babies and then they are weaned off the milk. In the natural order of things, that should be the end of it. Very crafty marketing. |

The homogenization process alters the shape of the lactose molecule. Since we only have one enzyme to digest lactose, we now have a problem digesting homogenized milk. No wonder we now have men in their 60's suffering from osteoporotc fractures, let alone the general epidemic of osteoporosis among women! |

well, to all of you out there in India, we buy cow's/buffalo's milk from the local farmer and boil it well. The cream forms a layer on top. Milk is used for drinking after removing this cream. To sour the milk for yogurt we use the cream too. Later the cream is removed form the yogurt (sour cream) and churned to make butter, so we drink a kind of de-creamed milk and those interested can consume butter otherwise. |

anon73499; Your comment is absolute science fiction. Cream does not come packaged in cells in milk (or at all for that matter). Cream is composed of a variety of fats, proteins, carbohydrates and other factors. The fats tend to gather into tiny droplets referred to as globules. These globules are not absorbed across the gut whole, they are broken down and each individual molecule of fat is absorbed separately. Whether milk is homogenized or not has absolutely no impact on the occurrence of heart disease. -Críona. |

Homogenization is the cause of the huge heart disease problem. The smaller cream cells go directly into our arteries where the natural cream cells do not fit. If I had the choice, I would never by homogenized milk! I shop at natural food stores, and still have a problem finding nonhomogenized milk or half and half. I have been buying heavy whipping cream because it doesn't say it is homogenized; although, it does say ultra pasteurized. Does ultra pasteurized mean that it has been homogenized? |

I manage a retail store for a small creamery in NE Iowa that produces non-homogenized milk. We have customers daily who report that our milk better and has a much longer shelf life than "conventional" brands. Shelf life is related to bacteria levels in milk which has little or nothing to do with homogenization. High bacteria levels= more organisms living, producing waste, and dying in your milk. Higher bacteria levels are a result of transferring milk from vat to vat which occurs in larger producers who receive milk from multiple farms. We have an ongoing list of over 500 people who are lactose intolerant who are able to drink our milk without having to take Lactaid or similar medications. They say they still suffer ill effects if they drink homogenized milk. The debate over whether homogenization is detrimental or not is ongoing. I stand to believe, based on my experience, that drinking non-homogenized milk is generally in a person's best interest. It is a more natural product than its counterpart which your body is therefore more readily able to process and receive only the enzymes, nutrients, and fat it truly needs. |

I grew up on a small dairy farm. I don't remember the milk being boiled. I remember skimming cream off the top of the milk can for house use. I remember butter being made at home. We made whipped cream using the old hand beaters. If a cow had an udder problem, we did not drink that milk. This took place in the late 40's and early 50's in central Michigan. |

Before there was homogenized and pasteurized milk, people would boil their milk, to kill any bacteria. Of course since the milk was not homogenized, some of the cream would collect on the top of the milk, while cooling.
The cream would be then collected with a spoon, and eaten either like that or spread on a slice of bread with a little sugar, it was usually meant for children. What a delicacy. This was not done often, and the amounts were rather small, but it was so delicious. |
