@@lorirarich1875 Yeah I've heard some people get sick from Lactaid. I have no such reaction to Lactaid personally. But I tend to perfer the taste of almond milk so I don't drink it that often. But if you were to use it in baking god forbid or simply drink a lot of the product, you would get the same effects as putting real dairy milk in your cookies. Making almond milk the obvious preferred choice as a baking milk. Or perhaps some other brand of milk that is 100 percent lactose free. For something like say cooking, soy milk might be a better option due to it not having a defined sweet flavor.

@FlipFlopAdventures Really? We got taught that in my high school biology class. Though the teacher of that class also couldn't figure out why some beans she boiled weren't germinating, so I suppose I should regard everything she taught with skepticism. It looked like it worked in the lab where we compared lactose levels of regular milk, milk with powdered lactase mixed in, milk that had been heated for 24 hours, and milk with powdered lactase that was heated for 24 hours. The regular heated milk still had lactose in it, but not as much as the regular milk, but it's also possible that the test tube we heated it in had previously been used for milk with added lactase and not properly cleaned (the whole class was an absolute train wreck, so I wouldn't be surprised if the teacher failed to notice some kids not washing the lab equipment properly.) I never actually stopped to question the results since the teacher gave us an A on the assignment. My apologies

I'm a chemistry student and we did a similar project, using different methods to create lactose free milk. The methods we used were different from yours and gave some interesting results. In method one we used the chemical properties of lactose to remove it from the mixture, by simply adding ethanol and letting the lactose crystallize. This gave some problems after with removing the ethanol but all of the lactose was removed. We also used a very small filter (similar to a HPLC filter) to remove the lactose. This also removed the fats and a very small amount of lactose still got through. In the end the project was fun to do because we were allowed to come up with our own solutions and gave some nice results

real milk doesn't really have lactose so you could just drink that instead

@Maheen drinking lactaid milk is even worse tho. because they just have more lactase enzymes to counter the increase of lactose caused by pasteurization. Raw milk has very little and has enough natural lactase. Lots of lactose intolerant people can't have lactaid milk but do just fine with raw milk. Not to mention the insane amount of real animal probiotics found in raw milk and fat soluble vitamins lost in pasteurization.

What's weird is that, for a human, it's actually the dominant mode of being to be lactose intolerant.

It would be more accurate to describe the minority of people descended from Northern Europeans that can drink milk into adulthood as "lactase persistent", rather than the other way around.

I've always wondered how this was done. I now understand why a liter of lactose-free milk is so friggin' expensive. Your videos are exceptional.

[@idah5496]

I’m form Norway, and the lactose free milk here have a much longer shelf life than the normal milk. Why this might be (btw I’m pretty sure we’re using a Finish technique. It might be the last mentioned mentioned that he couldn’t test, cause the taste of the two is pretty much the same, some thinks the lactose free tastes just a lil sweeter. Myself, I can’t really taste a difference Edit: ok so we have two kinds in Norway. Fist the one where lactase is added. The next one: the milk is sent trough a filter m, removing about 40% of the lactose. Then its made the anted fat percentage, then lactase is added to take care of the remaining lactose. This is the one with a much longer shelf life

[@ianmacaig2696]

The shelf life might be because it is UHT (ultra-high temperature pasteurization). If put in sterile containers, these can last without refrigeration for months, and in regular milk cartons can last a month in the fridge.

[@natalias374]

ultrafitration also gets rid of any microorganisms so it is a method of sterilization and a method of getting rid of protein

Hey Nile, thanks for uploading so many interesting and educating videos. I really enjoy watching them. Could you make a lab tour video, where you show your whole setup and which devices you use in particular (like your vacuum pump's make and model and so on)? That would be great - I am sure there is a lot of interest for this in your audience.

[@jordanhribar6002]

Asking for models is like asking for lactose free milk. Ask for the equipment specifications. Specify what milk is.

The reason I watched this video is to answer a question I’ve had for a decade, what happens if I drink lactose free milk with milk products with lactose. For some reason I thought the lactose in milk products would change my lactose free milk into lactose filled milk. Obviously I was completely wrong :) I love learning!

[@ScienceDiscoverer]

Obviously, you where completely right. There is no more enzyme in the lactose-free milk. If you add it to normal milk you will have end product with 50% less lactose, but still it will have it.

[@synhegola]

That was eye opening. Thank you for this!

[@Kara_Pabuc]

I really like the first method since it's simple and the end product is least processed also I usually put milk into my coffee and that added sweetness that caused by glucose suits well.

[@SPUTNIK18B]

Lactose free milk actually has a longer shelf life than ‘normal’ milk.. Don’t know why, but it’s a fact. Here in Denmark it’s 5 weeks, but I have even opened a carton of lactose free milk that had gone two weeks over the 5 week recommendation and there was absolutely nothing wrong with it..

Thank you for this video, it really explained a lot to me!! Also in my opinion, lactaid is superior 😆 I have a sweet tooth, though. But it tasted more like milk than fairlife. I always thought FL tasted more chemical-y, especially their chocolate milk. They got decent yogurt, at least. Lactaid's ice cream is also better than FL's, but the BEST dairy free ice cream is Ben and Jerry's B)

No. You don't get rid of the cream. Instead, you use the process of homogenization. That's where the milk is forced under very high pressure through very small holes.

which is why it's still mind boggling why you have to pay extra to get any kind of non lactose milk at a coffeeshop. While I get that non dairy milk can be more expensive, businesses should be prepared to eat the cost if there's a price difference with non lactose milk.
