- Most of us probably buy pasteurised and homogenised milk, but do have any clue what those two words actually mean?
Let me catch you up to speed.
Pasteurization when we heat milk up to a specific temperature for a certain amount of time to kill any disease-causing microorganisms in milk.
Homogenization is a little different. Here we disrupt the fat in the milk to make tiny, microscopic droplets. This prevents the fat from separating from the rest of the liquid.

I just bought a gallon of local milk that was pasteurized but not homogenized. Yes it absolutely separates but it’s so rich and creamy. It’s like little, light and fluffy pieces of butter in my milk…Not to mention it makes the best cappuccinos.
Yeah ... its definately not "oil". It's lovely, yummy, creamy, butter-like cream that is the BEST.
My 9 year old son ate nothing but a raw milk formula I handmade EVERY DAY for the first two years of his life (Sally Fallon's Nourishing Traditions book).
He went from failure to thrive and dangerously underweight to the 99th percentile in height and head size.
Pasteurization does kill bad bacteria, but it also kills good bacteria that's good for your gut. I have some people who are lactose intolerant that can drink raw milk, but not processed milk. That speaks volumes.
Lactose is a sugar, it's the same before and after pasteurisation
Talk to her about it. It's my doctor's nurse. She went in for gastric bypass surgery and came out lactose intolerant. I gave her some raw milk and she thanked me. She says the first time in over a year that she had a bowl of cereal. Go figure. She's a nurse. Guess she doesn't know what she's talking about, eh.
My Dad milked cow's when I was little, he kept them clean, he was kind to them, he had the highest milk production then his co-workers herds, we would drink raw cow's milk all the time, it's what they do with the milk, to high heat kills off the good stuff we need for our gut, I drink raw cow's and goat's milk and no problems, people need to do your own research on the benefits of raw milk and make your own decision.
The calves have to drink it without dying so obviously it’s safe to a degree. But I suspect that’s because of how clean his cows were. Milk is sterile when it comes out of the body.
Just like we know the risks of eating sunny side up eggs, same with drinking raw milk. As long as your cows are good, you should be good. I started drinking raw milk 6 days ago and to my surprise I actually was never lactose intolerant. It’s the enzymes and good bacteria that helps your micro biome that don’t get killed.No more issues! And the “oil” on the un homogenized milk is actually cream. Just shake it up and it’s f delicious ! Never going back to pasturized milk.
As a food scientist you should know it’s not oil..
Well said! I was always told I was lactose intolerant growing up. Only to find I wasn't, same as you. All those things my parents thought were true, was just them believing whatever Mr. TV told them. Now I'm giving them health advice based on my own personal research, and they have been amazed at the results.
The cream layer of milk is oil by definition. As someone with internet access you should probably do some research before spouting bs.
@@ChillyGoobue More like in the "fats" category but ok go on, was that all that sparked debate from my comment 🤔
@@ChillyGoobue Call it 'fat'.
You’re leaving out the part where babies were developing rickets because pasteurizing also gets rid of all the the healthy fats and nutrients.
The populace BLAMED these food born cases on milk but with no research on the matter.
Raw milk is the best, the problem is that all the commercial milk are from cows in not so pleasant conditions, grass fed cows the milk is perfectly safe and is tested daily
Also there are questions regarding Homogenised milk as it could possibly cause heart problems long term, also homogenised milk is much tastier
The only reason that typical industrial milk could be dangerous is because the cows are not kept in good condition and they do not follow clean practices. The industry cuts lots of corners in caring for the animals in order to save money and therefore yes the milk from the big industries is dangerous unless pasteurized. If you have a healthy, happy cow and you clean it before you milk it, whole, raw milk is very healthy for you.
Ridiculous… go visit any big farm before you speak this garbage…
I drink raw milk….it is so GOOD ! I also use raw heavy cream in my morning coffee 😊
Yes, and the cows should also be allowed to roam in the sunshine, grazing on fresh, lush grass. Instead, they feed them grain in the factory operations.
Nothing better than raw milk 👍
Drink raw milk. Dont know what they are doing over there but if you want clean fresh raw milk then just go to local farmer. Synthetic a1 milk is what causes side effects. Lady is talking out of her ass
First, it's cream not oil as others have pointed out. Having non-homogenized milk at the same price would be so much more useful as far as having cream for butter, ice cream and whipping cream. For the consumer homogenized milk is a huge negative trade off, in exchange for milk that doesn't seperate, it gives the dairy industry a conciderable control over how we use milk.
Oils (liquid) and fats (solid) are both lipids. Although cream is usually thought of as a type of fat, when she calls it oil she essentially means the same thing.
@@TheDAKing5 Thanks for the comment. As a consumer I would feel better about the dairy industry if we were given the choice of homogenized or non homogenized milk. It seems odd that this type of milk isn't available and the heavy cream sold has various thickening agents added. The result is the consumer can not make "pure butter".
@@TheDAKing5 Oils don't contain water, so cream cannot be an oil as it is typically around 59% water.
i am able to get a gallon of raw milk in my area online, it's a lengthy process , and it costs, for instance a gallon of store bought milk is like $4 ish, and i pay $11 for a raw milk gallon, plus shipping fees, but is the real thing, it's yellow, lots of fat, grass fed. and if you really want to be safe you can always low temp pasteurize it .
So in other words, homogenization is the process (which nobody asked for) of breaking up the "oil" in milk into smaller particles.
Good to know! If I ever find non-homogenized milk, I won't pass it up. According to other comments, it tastes better. Who wouldn't want that???
Homogenized milk is good for congestion of veins of your body, due to break up of the fat molecules, which creates a more congested circumstance in veins. So, homogenized is more devitalizing to ones body, it's more congestive. The nutritions is still there, but, the negatives are additional with homogenized milk. Homogenized milk is clearly promoting of erectile dysfunction. It's not the only thing causing erectile dysfunction, but it's a contributor, for those who consume homogenized milk products.
@@bonsummers2657 I don't believe that. I've learned that the accumulation of cholesterol in your veins is due to inflammation.
@@rorscach1 I speak from personal experience, repeated, over more than a decade paying attention to this matter. And, inflammation is mainly due to particular foods, especially concentrated fats, especially isolated seed oils, or concentrated fats, such as butter,… variable per person, but highly consistent in incidence. Excess of anything can be inflammatory.
Homogenized milk is substantially more inflammatory than non-homogenized milk, -the fat particles have been burst by the homogenization process and undergo an oxidative process which is significantly less healthy for the body.
If you've tried non homogenised milk then you will realise that this is the way milk is supposed to taste, creamy and full of flavour
Another thing is that the dairy companies remove the cream from milk and add it back in at the end before homogenization. Raw milk contains anywhere from probably 4-5% milkfat depending on breed and diet of the cows. Companies skim it off and you’re left with 3.75% in whole milk. The difference between the two is noticeable. Then they turn around and charge you $5+ for a pint of cream that has all kinds of additives in it. Its almost impossible to find cream that only contains cream. Very frustrating.
EXCELLENT video easy to understand what milk pasteurization n homogenization means
I'm glad to hear that!

That’s not milk after homogenisation and pasteurisation, it is a joke
I was watching a movie Taxi driver 1976 Robert De Niro was eating and I noticed unfamiliar written words on the milk box Homogenized and pasteurized then I searched for it here on TH-cam and By coincidence saw your video
Hah, that's so funny! I hope you enjoyed!
Go Raw!! A2 Raw MILK 🥛 has best tasty and healthy benefits for the body. Raw Milk does the body GOOD.
Correct. I do drink pasteurized non-homogenized full fat milk from a local farm. Raw milk is extremely hard to find where I live. Farmers are very skeptical to provide A2 Raw Milk because it's illegal in this specific province.
You just can't buy raw milk in a store or at farm it illegal. it's has to pasteurize or vat pasteurize to sell to the public.
I guarantee 100% if you go straight to the farmer you can buy raw milk you are just living in fear if you do what the government tells you to do they don’t need to know what you do with your life
@@campcreekhill8933The farmers living in fear, not me. They just won't sell it to me milk, I already tried ,can't buy something, someone won't sell.
😐
Great presentation I learned a bit about this subject but I have a question, Do or has anyone tried using the process of electrolysis in processing milk during the stage of homogenization to emulsify the oil in the milk with or by way of cationic or antionic ? And is homogenization done before the milk is cooled ? I wonder if bacteria could be removed or killed without heating the milk using electrolysis thus leaving the oils and fats intact ?
Get raw milk from s local farmer not big dairy farms. Infinitely superior in every way.
when raw milk clabbers-turns sour-it can be used very nicely in cooking. why does homoginized milk turn bitter and unusable in any way. how much bitter homoginized milk has been wasted over the past roughly 80 years when it turns bitter instead of clabbering?
Great point. The pasturised milk lacks the good bacteria that would allow it to ferment as it ages, which in turn raises the acidity and stops spoilage.
From what I've read pasteurizing also kills the good bacteria and enzymes and it reduces bio availability of many other vitamins and minerals making it of litlle value.
Hi John, some of what you are reading is not true. Here is a Q&A page about raw milk by the Food and Drug Administration. They point you toward studies you can read for yourself as well as simply summarise them.
@@AbbeytheFoodScientist Strangley enough there are many studies that show exactly the opposite. I personally have little faith in out FDA since it is heavily influenced by big agri businesse who profit greatly from FDA rulings. I live in dairy country and none of my friends growing up drank pasteurized milk.
@@AbbeytheFoodScientist Does that mean that most of what he is reading is true?
@@AbbeytheFoodScientist I've looked at my cow's raw milk under a microscope. It's beautiful - all those probiotic bacteria just jam packed in there. ❤️ It looks exactly like Yakult does under the microscope.
Unlike pasteurised milk which is an empty wasteland. I'll stick with what's good for my gut.
I want to know what milk has the least trans fats? Or even how the lipid molecules in milk change in this process. I want to have fatter milk and low-carb as I want to generate ketones. But milk is pretty much not allowed. So looking to understand the nature of milk fat after these processes.
Loved it! I'd love to see more videos in the future. Keep up the great work!
Cream is not oil. Oils do not contain water. Cream typically is around 59% water. The fat from cream can be turned into butter which is solid at room temperature making it a FAT, not an oil. Oils are always liquid at room temperature (and do NOT contain water) as opposed to fats which are always solid at room temperature. Big difference.
Great lesson Thank you
Glad you liked it!
Thank you!
Interesting how lactose intolerance wasn't really a thing when homogenisation wasn't the norm. Homogenisation DESTROYS the buttermilk, it doesn't "break it down into smaller droplets", to such an extent, your body has no idea what it is anymore and it treated. Pasteurisation is essential however
Homogenization is just a byproduct of hurrying the cool down portion of pasteurization. Spraying the hot milk through a stream of very cold air makes the process cost less. The small homogenized fat particles are not handled well by the human body. Also the mouth feel of homogenized milk Is watery compared to non-homogenized milk with a lower fat content. For the healthiest, best tasting milk, buy skim milk and add a small amount of whipping cream and just shake the carton before pouring. Low fat milk with creamy taste. Half and half IS the most harmful milk product sold in the United States because of the extreme concentration of homogenized milk fat.
Why add a manufactured whipping cream, when it is already there naturally?
How about if you blend the milk with cream?
Why does homogenized milk make for a whiter coffee compared to shaken natural milk, both containing nominally 3.5% fat? Of course I would drink the Cream ("oil"). It's a luxury product. Something you wouldn't want is a home treated milk at 100° with a film on top.
I think the primary reason for heat treatment is actually shelf life. Especially in America where a typical container is a whopping 4 liters. No need for shaking over the lid also helps. Melk used to go bad in a couple days, but simply go sour and form edible curds. The diseases were some isolated cases blown out of proportion. Today unpasteurized melk with refrigeration throughout the harvesting process is often good for 4-5 days, and is practical to buy again.
It looks whiter because all those tiny oil droplets are what actually refracts the light.
I can see that in defrosted cream as well which separates out the butter and doesn't make coffee white anymore. Is there a difference between boiling milk for 2 minutes vs 20 minutes in a porridge? People who add milk late couldn't not explain why they do it.
Perhaps you can explain the interaction between food and stainless steel on a chemical level, why it creates a plaque that is difficult to clean off without vinegar.
It could be that milk that's added early on undergoes some browning reactions and might give a slightly different flavor. If it's boiled for longer you are also concentrating all the solids like fat, proteins, and sugars which might alter the taste.
@@AbbeytheFoodScientist you are brainwashed
So is homogenized pasteurized milk good?
No, homogenized milk causes cancer on the long term
Yeah

Interesting.. you have any sources to back what you’re saying?
@@hanzalamehmood2991 My own body results. Very clear. Other people share their experiences online too. Look around. Homogenization results in phlegm production, and reduced vein flow,…. - one example being erectile ability,… which is more so true when one is beyond late 30's in age. Diet is key,… with prime-vital foods.
There is a good reason why raw milk is hard to find. And no, it's not for YOUR benefit.
nice video! and also the topic of your channel is really important. thank you! liked and subbed 👍
Educational!
Personally I love the tasty delicious raw milk, also it's cream not oil, are you trying to turn people off by calling it oil? You just shake it before you drink milk so the cream is all mixed in
Yes, she has an anti raw milk agenda.
@@JebidiahMahaney It's foolish because raw milk is incredibly nutritious.
@@JebidiahMahaney Well they don't even sell raw milk to public in my store anyway it's illegal... if you own you're own cows that's great you can drink raw milk anytime you want but most us can't just go out buy it in the stores
@@wonderwomen5297 it's legal in a few states. Including California
@@JebidiahMahaney Oh ok not my state ,My state you can't even buy it from the farms
its sweetened condensed milk same process ?
Sweetened condensed milk is pasteurised but then we use evaporation to concentrate the solids :)
Who would not want a cream layer?
When I go to my fridge and I find that the cream (it is fat, yes, but using the word oil invokes a highly inaccurate imagery) has settled to the top, someone i will carefully pour it over my cereal to boost the fat content. So much more flavor, and since it's rich and flavorful raw milk, no one else is going to mind drinking 3% milk instead of 5%.
VERY CLEAR PRESENTATION. I ENJOY YOUR VIDEOS AND LEARN A LOT OF INFORMATION.
Great video
Thank you Abbey for making these videos. May I share with you a way to pasteurize milk?
But people were drinking raw milk for thousands of years and it wasn’t until an incident before 1918 that we started heat treating our milk
people also died to the flu for thousands of years
I don't drink melk, only milk.
Hey Abbey: You dear maddam are a wizard of the highest realms of creative existence! Because of you, I'm waaay more in the know and more confident about my whole milk choices. Cream being oil being fat (lipids) that float atop of unhomogenized milk makes so much sense and indirectly answers questions regarding my use of heavy whipping cream! You have that 'it' factor that makes me want to learn about food from a scientific perspective.
I do have one question though and its related to my lifestyle of weight training (body building): Do you happen to know whether drinking milk through ultra heating (300 degs) does any damage or rearranges the profile of proteins and fats? If so, then I might steer away from it. If not, I'll give it a try -as I see them on palates just outside of the Costco freezer Dairy section and had been wondering for months, why they were allowed to sit at room temp! I assumed they added something to the milk which allowed it to stay at room temp...That was until I had the good fortune of getting more educated and coming across your channel! Wanted to thank you for the content, it's definitely caters to my style of learning without being dull, boring, with too much over-my-moronish head to understand each of the barebone processes while putting it all together : )
Thank you so much for the compliment! It's always good to hear from people and helps keep me motivated. I've been doing some reading into your question about UHT milk. I can't find any papers that give a specific number or quantity about differences in protein or fat but did find some trends. It seems to be generally agreed that UHT processing makes some amino acids nutritionally unavailable, some proteins are used in the Maillard reaction at these high temps, and it altered how the proteins are digested somehow. Like I said, I couldn't find a great source that said how significant these changes are, but with your lifestyle I would just stick with pasteurized milk.
Are you trying to get layed😂😂👍

Good explanation and I will always drink homogenized milk. 💪🏾🐄

What's Melk???
Homogenized milk sucks.
It should be noted that raw milk can be purchased legally in 49 of 50 states in the US
What is this 'Malk' you talk of ....??
As another commentator pointed out, your anti raw milk agenda is clear in many ways, especially the part about the the non homogenized milk having an 'oil' layer on top, when it's just heavy cream. Thumbs down for you, bye.
Well actually, she's right. U can call it fat, grease, oil, or cream, cream sounds more, pleasant so, but that's what it is.

In the Eastern countries, for centuries and even today in the rural areas, milk is consumed only by boiling ( not pasteurizing) and no homogenization, when the rural folks moved to city and started drinking pasteurized and homogenized milk that’s when the auto immune disease like rheumatoid arthritis and other chronic diseases started rising.
.
Boiling is the same as pasteurisation. You are heating the milk up to kill microorganisms. My grandma who group on a farm said that her mother always boiled their milk but she didn't realise until I made this video that it was killing the microorganisms.
boiling is pasteurizing.
There is no oil in milk
Actually, cow comfort and cow health is, on average, better now than in the past. A cow that is healthy, comfortable and fed a carefully formulated diet is the most productive and profitable to dairy owners. Why would a dairy person want to feed bad stuff to their cows or hurt their health? Think about it. Dairy people like their cows, drink the milk they produce, and want to stay in business! The people who are the most unhappy about dairy farming today or dislike the milk that is produced are invariably the least informed about it (60 years experience with dairies and an animal scientist here). I appreciate the desire for animal welfare and food wholesomeness, that is great and I am glad people value them. But focus your efforts on more problematic areas in life, such as helping people avoid food borne illnesses from poor food preparation, lack of access to health care or homelessness. These are real areas of concern.
I’m not sure why it has to be homogenized. like who cares if the oil is on top shake it
Milk is tonic to man with out lactobacillus…
When you drink pasteurized milk , you’re drinking the dead organisms. Raw milk is great for the body. Nobody in history has ever died in the last 15 yrs because of raw milk. I’ve been drinking raw milk for years and I will continue to drink raw milk. I’m still alive so there’s nothing wrong with raw milk. I live in the USA 🇺🇸. I’m drinking raw milk and eating cookies as I watch this.
To each their own.
As a nurse who gets Science😉 her explanations are superb. What I’d like to know is…is Half ‘n Half half milk & half water? Or is it half cream & half milk? Excellent presentation. Very animated which makes it much more retain-able Education!👍🏻
So happy you enjoyed the video! Half and half is generally half whole milk and half cream. But if you want to know the definition by US law, it's a mixture of milk and cream which contains 10.5-18% milk fat :)
@@AbbeytheFoodScientist -Well at least we’ll know why our Lipids are high…but it’s worth it! Thanks 🙏🏼 for your excellent presentations. I’ve watched several others of your videos & they def. do not disappoint!
This video is full of disinformation. Just one example is using the word oil for what's really cream. Instead of homogenizing milk, when the cream rises to the top, simply shake it up to mix the cream back in, and all's good. And raw milk from pasture fed cows that are well taken care of is perfectly safe. I drink it all the time, and the taste is so much better than the rubbish you buy in supermarkets. I really hate that TH-cam disabled the visibility of dislikes on videos. I'd like to see how many this video got in addition to mine.
It's not disinformation to call cream "oil." Cream is a fat and oil can be used to refer to melted fats.
@@user-fq7ii3ub4m It is actually - the difference is that oil doesn't contain water. Cream does contain water. And the fat in cream can be made into butter which is solid at room temperature making it a fat, whereas oils are never solid at room temperature. They are two quite different things.
Nobody mentioned that she's saying melk instead of milk...

As reading all the 'smart' comments, just imagine you being a big industry with hundreds of cows, you sell your products and maybe 1% of people eating your products will become sick and then you got a problem. In fact, industries have to obey very strict rules, the hygiene can be even better then at some farmer's home owning 5 cows. However, people's resistance to bacteria and other microbes is different, so raw milk drank by you may be harmless, but it can cause harm to another person and industries just can't risk that. Peace.
I wonder how baby cows ever make to adulthood. And maybe breast feeding mothers should pasteurize and homogenize their milk.
You have to remember that microorganisms typically cause disease only in certain host organisms. A bacteria in a cow might cause no problems but once in humans it makes us sick and vice versa. Additionally, mother's milk has antimicrobial and immune compounds to protect their young while feeding.
It never made my grandparents or ancestors sick.
Thank you for clearing my doubts
Very misinforming
Wonderful lecture 🙏
Our family drank raw milk back in the 70’s. I feel cows were fed better at that time. Now I wouldn’t drink raw milk only because of what they fed the cows.
Depends on how produced.
That's why you buy from local farms with grass fed cows
Raw milk is incredibly nutritious. Clearly you did very little research about the pasteurization of milk given the information put forth in this video. Or if you did do proper research, you purposefully omitted vital scientific information to suit your anti raw milk agenda.
Whoa whoa them fighting words. I'm on your side but don't attack her and accuse her. If anyone has an agenda it's the big industries and lawmakers. A lot of times they hide the truth to make more money
you talk very sloow
Raw Milk it's illegal in US because has benefits to someone´s health, not so good for America´s farma Inc. Every morning I drink raw milk and I´m very strong and beautiful and smart.
Ever see an Amish kid get sick from drinking raw milk? Nope, neither have. Raw milk when it's drank fresh is the best milk there is.
