It might sound a little fifth-grade-science-project-y, but shelf-stable milk is just milk that has been pasteurized and packaged a liiittle differently than refrigerated milk in order to extend its shelf life. But there are plenty of reasons to get behind it. Many have noted that because of its durability, shelf-stable milk might be a more environmentally sustainable option.
This hot and fast approach kills nearly all bacteria in milk and is referred to as UHT ultra high temperature, or aseptic pasteurization. As for non-dairy milks, most are pasteurized and processed in the same way, meaning that shelf-stable products will last longer than refrigerated ones. Most of the milk drunk in the United States, Australia, and New Zealand is of the pasteurised variety, says Hilton Deeth, a dairy expert recently retired from University of Queensland.
The milk can be stored for many months thanks to the sterilising effect of heat Credit: iStock. However, in many European nations, UHT milk is the norm. This milk is heated to double the temperature — C — for a mere three seconds.
The high heat does its work almost instantly, killing all bacteria and most of the bacterial spores that can stand up to lesser temperatures. Because it's nearly sterile, as long as it is packaged in a container that's aseptic, it will last and last. No bacteria means no spoilage, at least as long as the package is closed.
You can't do just anything to UHT milk, cautions Deeth. It's designed to last at about C, so if it's shipped across the equator on a sweltering ship, or languishes on a dock somewhere in the tropics for a while, some of those remaining spores may come active and cause problems. And peculiar things do happen sometimes to that everlasting milk in its cloistered existence. The reason that happens can be found in the chemistry that goes on during its treatment and which contribute to some of its odd qualities.
Another thing that makes aseptic milk last on the shelf involves the sterile packaging and sterile environment in which the packaging happens. First, the bottles are produced on site; they are then sterilized so that they are absolutely clean.
Secondly, the milk packaged in those bottles is in a sterile environment so that no bacteria or pathogens can contaminate the product. The combination of UHT pasteurization and bottling sterilization ensures that the milk lasts up to six months on the shelf without refrigeration. The aseptic milk is made with the same delicious, fresh and high-quality milk from local dairy farms. While pasteurization has helped provide safe, nutrient-rich milk for over years, some people continue to believe that pasteurization negatively affects the nutritional profile of milk.
That could not be further from the truth. In fact, there are no meaningful changes to the nutrient package of milk as a result of pasteurization.
Raw milk contains a miniscule amount of vitamin C 3. By comparison, orange juice contains about 84 milligrams of vitamin C per serving. Drink your milk and enjoy it. I lived in Europe for many years, and while most milk there is fresh some people do use UHT.
I have to say that sometimes I prefer the taste of UHT over plain regular milk. In tea, for example, it imparts a unique taste that I find myself craving from time to time. My daughter is 24 and recently developed an allergy she has never been allergic to anything before We suspect that it coud be longlife milk or something in it that causes the allergy as this is the only change she has made to her diet she used to stay at home where we never used longlife milk and now lives on her own and now only uses this stuff Her lips swell up like balloons and she gets these itchy red blotches.
My question is how long does it take after she stopped using this milk for all traces to be out of her system? She stopped using this milk about a week ago but still has the symptoms. Any comment or advise will be greatly appreciated. What about zoonotic diseases that can be contacted via drinking of raw milk? Where i live in the world zoonotic diseases are sometimes present in raw milk..
UHT milk is definitely safer for human consumption from a food safety perspective, ppl can get really sick from drinking raw milk. I much rather drink burnt milk than milk that may get me sick. Hi, this weekend is pleasant designed for me, since this moment i am reading this great educational article here at my home. Hmm is anyone else experiencing problems with the images on this blog loading?
Any feed-back would be greatly appreciated. And if kids drink too much milk it can cause internal bleeding…. I love raw milk. UHT milk is dead dead dead. Raw goat when I can get it most of the summer. Non UHT grassfed organic non-homogenized cow milk the rest of they year. Thank you for posting this!!! We JUST started drinking raw milk yesterday. We will be picking some up every week while on the way to pick up our organic CSA fruit and veggie shares.
So lucky to live in an area where I have access to these wonderful things! Raw milk tastes divine. I drink local raw grass-fed milk but now I am scared after hearing reports of roundup ready grass :. It really opened my eyes to read about the UHT pasteurization. Thanks to anyone with advice. Makes me sad. Going to have to look harder.
Can I point out that humans have been consuming cooked milk for thousands of years and probably longer? It was very common for the food to all be put into a soup or stew. Anyone who had milk at all considered themselves to be extremely lucky, and this would very often have been added to such a cooked concoction.
See, Roth-Walter, et al. Allergy — Also, pasteurization of milk has virtually no effect on the digestibility of casein, according to the published literature I have looked at. The protein nutritional quality of Fresh UHT is almost the same as pasteurized which is in turn almost the same as raw. However, Recombined UHT milk is lower, and is ssignificantly lower after storage for six months.
See for example, Alkanhal, et al. Changes in protein nutritional quality in fresh and recombined ultra high temperature treated milk during storage. I should also mention that differences in immunogenicity for processed milks are not primarily due to changes in digestibility of various protein fractions. The effect on casein is negligible. So immunogenicity changes due to heat treatment are not due to alteration of digestibility. Roth-Walter, et al.
Peter R. Kramer, Ph. More poorly documented hogwash. Allergies to milk resides in the fact that humans are not cows thus we are liable to suffer allergy from a host of foreign proteins and sacharides present in cows milk. In old times children with milk allergies were simply fed the milk from other animals, for example goats. At present they are treated with almost completely manufactured protein and sugar assemblies that hopefully include all essential nutrients elemental formulas.
The simplest way to eliminate the issue of milk allergies in babies is simple give them the milk they are supposed to eat, human milk. Again in old times if impossible from the mother that was provided by wet nurse. Human and cows milk are almost diametrically different, human milk is mostly fat, essential to us because or most important developing organ is the brain.
How the milk is cooked has little if any additional antigenicity to that already present form the difference in species. Human, goat and sheep milk rarely causes a problem. Nor does cows milk from the heritage breeds like Jersey, Gurnsey, French Normande, etc. They all have A2 protein. Holstein have A1 protein and are likely to cause dairy intolerance. I found this out with my daughter with severe allergies to Holstein milk which is the most common milk cow in many countries.
Switched to Jersey and her severe reactions to milk stopped immediately. Im just amazed at how the internet facilitates anyone with a computer to blab nonsense about subjects they have no inkling about. UHT is MILK, it has all the nutrients that milk has, it has no additives and if taken from organically certified cows has no hormones and no antibiotics. Yes the taste is a little different, personally, I like the taste.
It has the advantage that it can be stored at room temperature for 6 mths and refrigerated up to a year thus making excellent tasting milk essentially a non perishable product. Only a an ignoramus would believe, that raw milk, Which comes from the fecally caked teat of an animal containing listeria, bovine tuberculosis Ever heard of Potts disease?
Raw milk tastes great until you get sick or someone dies from it, then its not so good is it? Since the raw milk mania has taken root the outbreaks of listeriosis and milk borne illness have increased ten fold.
All completely unnecessary and costly in human and economic terms. So, what do you buy? Are there even any regular grocery store brands that are not ultra high pasteurized?
One offering is not homogenized as well. This disgusts me. Thanks for sharing, I will try to watch out for this when buying my milk from now on. Me too. And even brands like Organic Valley do it. Grass fed in season too. Organic milk is more likely to be ultrapasteurized because the milk is harder to get, more expensive to produce and needs to keep long enough to be distributed over a larger area in order to reach the smaller customer base.
UHT is not for our good at all its all about making milk products seem to last longer. I hate that all the milk and cream are uht now and I wish it had never been invented. Never have I or anyone I know had burnt milk. Same in Europe where I spend much of my time. And so much is irradiated, loaded with chemicals, adulterated and genetically modified. I prefer Mother Nature and her amazing bounty.
I feel for those who cannot find raw A2 protein cows milk. I wish I had my own garden, cow and chickens. I will have a garden next year, I can buy eggs from a friend who raises them free range, but I have no way to buy any other of the recommended items. What is a person to do? I am very confused. Lore- you can try looking on realmilk. I hope access to raw dairy locally just continues to spread.. Sandra, could you just send it with a reusable ice pack? Neither one is better or worse than the other?
I have a local farmer who does low temp pasteurized non-homogenized grassfed milk. Or I can drive two hours for raw. I buy Kolona and Organic Valley Grassmilk. Both organic, non-homogenized, and low temp pasteurization. Still, pretty sure milk from Guernsey and Jersey my favorite cows is far better than the milk from the far more prevalent Holsteins.
Here in South Africa we have quite a choice of different milks. My first taste of raw milk was as a child, it tasted weird and had funny lumpy bits in it, and it put me off fresh milk pretty much for life unless flavoured, in cereal or in beverages. Decades later, as an adult my family and I lived in a rural area where only raw milk was available locally. My doctor warned me not to let my children drink it without boiling it first and preferably buy long life milk when we did our monthly shopping in the closest town.
On a few more years and we ran our own dairy farm and although my family all drank our raw milk from our own cows, as we knew what was in it, I still did not like the taste or texture. Only then did the memory of the horrible lumpy milk I drank as a child surface again, and with greater knowledge I realised that the cow that produced that milk probably had mastitis. So after all the pros and cons in these comments, my advice is, if you are going to drink raw milk make sure you know which dairy farm it comes from and what exactly is in it.
Even raw milk can be filled with antibiotics, hormones and bacteria that can make you really ill. Incidently I have been drinking only long life milk for going on 20 years now, and have had no issues with it.
Quite honestly I also believe that humans are not really designed to drink vast quantities of cows milk in whatever form, especially as adults. But each to his own.
You just scared the living daylights out of me. We were taught in school that UHT milk is good cause the high heat kills all the bad bacteria in it like boiling water. Now I know better, no wonder I never really liked milk except the ones that are pasteurized normally. There is honestly nothing wrong with UHT milk. The process uses high heat to kill bacteria and give it a long shelf life.
If the milk is certified organic it does not have any added chemicals or preservatives. Besides, I personally love the taste of it. Not even remotely. I drink organic soy or rice milk. Organic and not made from GMO soy or rice. To me the milk boxes taste absolutely delicious, I like their flavor more than raw milk.
Reading all of this info about denatured proteins and corn carriers causing autoimmune reactions etc. Millions of perfectly healthy people drink this UHT milk and never have an autoimmune issue. If so can you please provide me the medical journal information so I may read the studies about UHT milk and autoimmune disease myself? Much appreciated thank you! Starbucks have changed to this UHT rubbish in China and people are complaining as Strabucks ignore the problem.
In Australia Starbucks has failed. The same will happen in China as people realise the bad health issues from this UHT product. People are gulable and neive. Its criminal to take avrwal product and destroy its nutritional value to just white water. Starbucks compitors are not so stupud. Cows produce milk whether they have just had a calf or not. I use soya milk instead and a few years ago I switched from fresh to UHT soya milk.
There was no noticeable difference in taste but this may be different with cows milk. In your post you say that heating milk denatures enzymes in the milk so that it cannot be digested. I would dispute this. Enzymes in the gut are what break down the proteins in milk and so it makes no difference to them whether the milk is heated or not.
I also think your comment about commercial milk causing leaky gut syndrome needs some supportive evidence as it is such a big statement to make. While raw milk probably does have health benefits individuals should be aware of the risks associated wtih it before consumption. To make such big statements one needs to present clearer independent peer-reviewed evidence and without it the authors should be held far more accountable.
Fear-mongering around food topics is high these days and it needs to stop. Authors deliberately create controversy to get more traffic, comments, debates, etc. The contents with valuable information often mixed in with extremes, not to mention followed by gloomy and even impractical suggestions.
They are now passing it off as half-and-half. UHT has such a nasty taste. I refuse to get a cup of coffee if all they are offering is UHT crap. We need to take back this country. People believe this stuff but have no problem putting fluoride a toxic waste into our drinking water. I puzzle doctors all the time. All they can do is shrug their shoulders and tell me, Lose some weight.
FYI my family members have all of the afflictions people would assume. I am an American that lived in Germany and Switzerland for several years at two different times. You will always find a supporting piece of science when it comes to food and drugs to support your bend. Want you kids to grow breasts? All of Europe and Asia and the Middle East would be in huge doo-doo for the number of decades of drinking problem milk. They have social medicine, motivation to remove problem foods, like huge buckets of sugar pop, GMO, Roundup ready seed.
The gluten free selection is mind blowing, the and the general approach to gluten free is supportive, unlike here. You have a skewed view based on your culture and the cohort cold milk you seem to support. I have casein morphine effect and with UHT milk I can drink milk without a problem. I agree with you that Horizon tastes strange.
I have no clue what they are doing to taste so odd. In Europe the number of brands of milk would make your mind spin! I also appreciate they use a different species of cow in Europe. Relax and learn the milk situation of much larger and so costly here.
Maybe you ought to write a scary article about European eggs. They sell them warm, sitting on tables the way we sell donuts in the grocery store. You are so wrong… Please live in Germany and take your fears there and tell them about the terrible food they eat, terrible health care they have, and how they are going to UHT drink their way to a early death.
I SMH!!!!!! You embarrass us Americans and give us the reputation of ignorant. From afar it seems like a another terrible thing of Europe to have a small kitchen fridge.
I loved living in Germany, it was nice to buy 10 gallons worth of milk at one time and store it in the pantry. I loved the taste too. We spend lots and lots of pollution running around getting milk, or milk delivery WEEKLY, much less the whole cold processing of stores! Do your homework first before you make outrageously false claims.
You would do better to really inform people of the facts. This story is extremely dangerous. If you farm and have direct access to raw milk and are comfortable with sterile techniques then this may be a viable choice but this is potentially a very bad move for I have a niece that has permanent kidney damage from drinking raw milk as a child.
Please be more responsible with your words as these words have the power to do great harm. Pasteurisation has saved probably millions of lives since its introduciton. I say thank God for pasteurisation and the lovely taste of UHT milk. Studies in London show that UHT.
They think raw milk carries a TB like substance that causes the disease in those of us who cannot tolerate or fight it. I say yes to UHT milk any day! And I am upset, frankly, that Canada does not have a very large production of it. They started pasteurizing milk in the first place because raw milk can have the toxic lifeforms that pasteurization kills. The fact that Lee Dexter is associated with a non-pasteurized dairy would lead me to doubt that the article on UHT is unbiased.
The high acidity of the human stomach causes the proteins in milk to denature, that is to loose their folding structure. For children raised in western Europe, this is how milk tastes. They would find unpasteurized milk to have a funny taste. Good taste is often to what you are accustom. Organic milk is UHT because it is a niche market.
Drinking unpasteurized milk is rolling the dice on health. If prepared under sanitary conditions and consumed quickly, it presents few risks. But with every passing hour, there is a risk that pathogens are multiplying in this ideal growth medium. I posted a very similar comment before reading this one. Thanks for bringing some actual science to the comments section.
It seems that places like this turn into an echo chamber for pseudoscientists to post their unreviewed, unsupported claims and just get away with it. In this case, it really does endanger people and there needs to be a little accountability. That was really the main argument against it. Now I buy UHT by the caseload and love it. But what if my grocery store does not permit me to buy milk by the pint?
I live alone and ordinarily use only a dash of milk on my cereal, so that I cannot finish a quart before it goes bad. When I tasted Horizon milk, I thought it was the best milk I had ever had.
Still do. The shelf life is five times longer than regular milk. The only problem is the high price. I love uht milk. Thanks for your thoughts, made me feel better that the uht milk is safe, unless you have a rare health condition. I think your conclusion is degrees out from what the author was trying to say, but I agree with you. I also love the taste of UHT milk and have no ill side effects from it.
In third world countries there are a plethora of diseases in raw milk. Cows can get TB. These infected cows could give people with a weak immune system e.
Raw milk contains a higher amount of bacteria compared to regularly pasteurised milk, let alone UHT pasteurised milk.
Especially for children and the elderly and really anyone with a compromised immune system , pasteurisation as an important safety measure. Yes, most raw milk today is safe due to safety measures other than processing. However, if something does go wrong on that end, there is no pasteurisation to keep out dangerous bacteria that could cause serious harm.
I mean, first of all, there is little to no evidence that raw milk has any benefits over pasteurised milk. Most organically-produced molecules are, as a matter of fact.
I was a 70s and 80s kid. I grew up drinking lots of whole milk. Back when it was frothy and bubbly. I went to camp one summer and they had a milk fountain. Us boys would run for refills every chance we could get. Bubbles runneth over! We knew it was good for us. But I know what milk is today. It isnt even milk. The government is clearly hell bent on destroying all good things in the world. They showed that when they came to America to rape the land.
That quoted statement is certainly true for much of Europe where UHT milk is much more common.
