Oh my God Karen, you can't just ask sugar why it's white
It’s okay to be white.
that's RACIST!
It's okay to be HUMAN, clxwncrxwn, cause at the end of the day, we're all the same species.
Can you ask *brown sugar* , _"why do you tastes so good?"_
Only Mick Jagger can get away with that one.
Some bad editing choices was made making this video. Loud music when people is talking is just annoying.
Magnus Hellman FREE SERVICE.
When?
when you compare it to american productions of like how it's made, yes definitely poor editing choices. It felt choppy to me, they jumped from things to fast.
Natural sugar cane is amazingly better. Tastes better. And nobody tried to make it white. It's just yellow. And I don't mind.
Sugar beet is also GMO
Oh they do make it white. We used to export it to be refined for that purpose. I grew up just using the brown/yellow sugar but we only kept white sugar around in small amounts for baking since it's more expensive here than brown sugar.
@@babagandu so?

Sucrose is sucrose. Natural canes are grown in places with many human rights violations. I'd rather my sugar doesn't taste of human suffering.
The music is like something fresh out of Tom and Jerry.
The music is so loud that I barely hear him :/
How would the world be with out sugar ? We would be healthier.
You should do yourself a huge favour and watch some Durianrider!!
That Factor is making slow poison
Real questions: How do they make sugar from sugar cane? How do they process stevia and reduce it's volatility, as in it's raw form it breaks down quickly? I'd also like to mention that some TH-cam chemists have refined sugar in small quantities to white sugar crystals without to much hassle, and he said he doesn't use a filter, but you pointed out correctly that the lime acts as a filter.
The process is not that different, the canes are passed through a machine that squishes them flat separating the "cane juice" and the plant fiber, also called "bagazo" in spanish, the juice is can be drinked by itself, fermented into rum or other spirits like guaro and aguardiente, cooked into brown lumps or candy. To make sugar the juice is cooked until the glucose and fructose combine into sacarose (something like reverse hydrolisis, dunno i'm no chemist) and the water content is suficiently reduced. Eventualy the mixture will be dry enough to crumble as crystals of impure sacarose, called brown sugar. It can be further processed by "cleaning" it with sulphur gasses that pull the impurities rendering white sugar. The bagazo is burned to produce electricity and heat for the plant consumption, believe it or not it is quite environmentally friendly as the same amount of carbon dioxide released by the combustion is fixated by the sugar cane during its life cycle, which is quite short. (This is by no means the way it is done everywhere, but it is as close as the explanation given to us on a field trip to our country's biggest sugar refinery (in Grecia, Costa Rica))
They used the term "filter" but to be more precise they should have said "flocculant". Look it up :-) Flocculants are also used for cane sugar.
Of course they use a tea analogy
Is it just me or did they completely fail to answer the question?
That's what they do on this channel- barely answer questions in the title.
Because they show just 3 minutes of an episode that was probably 20 or 30 minutes long. It's really annoying.
Me too
Thanks for the heads up. I’ll stop watching now.
sucrose molecules, when formed into crystals, are naturally white if devoid of all impurities (color). Nothing is done to it chemically to actually alter the color of sucrose.
I thought sugar comes from sugar cane
It actually do...but there are always alternatives...
If this video doesn’t inspire you to stop eating and/or consuming anything with sugar (including sodas), I don’t know what will.
Pretty simple process actually, just the Lyme and co2 that's probably the hardest step
@@sealishproductions actually no, this video is increadibly misleading. If you notice he said they only use the Lime and CO2 to "help clean" the liquid. There are dozens of more processes and chemicals used that they did not disclose. They use various extracting agents during the boiling process to facilitate the extraction of the monosaccharides, they use various gasses during the centrifugal process, there are also about 10 or so additional steps involving various solvents and intermediary substances in order to get maximum crystalization, depending on which base material is used (beets, sugar cane, etc...).
Quotes from two women 100+years old: "Eat sugar and butter, don't worry." "Always have dessert, always."
I really wish i could get a small tabletop version of that centrifuge. I want to grow my own sugarcane and don't really need a 5 thousand dollar piece of equipment to process a small lawn of cane.
If the beets only contain 17% sugar as the resulting end product, what is the remaining 83% used for? …. and where does brown sugar come into play?
brown sugar is made by adding molasses back into the white sugar. As for the 83%. That's all the pulp, skin, and other plant bits, not sure if they use it for anything or if it just gets tossed.
I was thinking the same thing.
Maybe it's used for fertiliser or feed for livestock? Not sure either.
They could really increase their profits by selling that stuff to compost reactors and combustion powerplants
It's mostly water but the pulp is used to make animal feed.
@@martinrauch8556 The pulp is dried and beet molasses added then turned into animal feed
'Cause no one would eat black sugar. (It's just chemistry, people.)
2:00 Carbon Dioxide
This is Newark Sugar Factory , there are now only 4 in the UK , i work there too , seems odd haha !
Pls is there any basic way to make sugar white at home?
It's a lot more complicated than I thought. I imagined that you just had to chop up the beets, boil it, strain it and boil it again to get rid of the water.
I imagine that's probably how they did it pre industrial revolution. Yield is probably not as good and you have some impure flavour
What happens to the rest of the sugar beets, the parts that are not sugar? How is the process different when processing sugar canes?
Probably fed livestock or turned into fertilizer.
Cheers Jeff
3:32- 3:34 what are the words after washed and before filtered? I didnt understand @bbcearthlab
Steeped
They probably turn the leftovers of this process back into brown sugar for double profit
Correct, the "leftovers" of a sugar plant is what you would call molasses. That would be purified further then mixed with refined white sugar to create brown sugar.
I'll take pure cane sugar thank you.
Why brown sugar is more expensive?
Brown sugar is normal sugar with molasses mixed through
Because #Racism
Because it's made from sugar cane
Norma it isn't made of sugar cane. At least the these that I saw on store shelfs
because its "special" and so pay more for it even if it costs less to produce. Stupid people will pay more for stupid products.
The chemicals stay on the finished product or not
Wait, no no no no, know I wanna know what they do with all the unused beet parts, the chalk and so on !
the chalk is recycled and reused whilst the remaining unused solution is made into livestock feed or into fertilizer.
What’s the spray name which change the colour of sugar?
Called bleach
What about cane sugar? I've never seen or used beat sugar...
Cesar Perez tbh, probs a v similar process. Grind sugar cane to juice it. Apply lime solution etc.
most likely you are consuming sugars based from the beet variant. Unless you're in a more tropical area where sugar cane is more abundant.
Does sugar have bone char
This is a question you can’t ask in 2018.
Fank Daggot I wonder when black and yellow teeth come into fashion))))
Why not?
Do you mean you can't ask how is sugar made white?
many refineries use bone char instead f sulphur dioxide to make sugars white
British Sugar use Sulphur Dioxide to help clear the juice .
Why not make it from sugar cane? Tastes better, but would probably be more expensive as you would have to import it.
ouroesa sugar cane doesn't grow very well in the UK. The yield from sugar beet in the UK and Europe generally is high. Many tons per hectare of land.
Some of the waste lime goes in the manufacturing of wall boards, pavements, roofing etc. The beet molasses goes to animal feed, plus the leaves and tops. 🐄🐑🐐
What about the sulfur they use and don't tell us..!!
Exactly !
I’m waiting for black sugar
In our country sugar process from #sugarcan. And #palmtree ... You showing new kind-of Root ball
👍👍
Where does the other 83 percent go? It would be interesting to contrast this process with Sugar Cane from other parts of the world, and the USA obsession with HFCS
they would use it as fertilizer to grow more beets, most likely. Or sell it for the same/similar purpose to someone else.
The left over beet pulp is dried and used as fodder for horses and other livestock. After they removed the sugar and the water the rest is high in (longer) carbohydrates, fiber and proteins.
Not exactly correct, YES the U.K gets most of its sugar from sugar-beet, but the U.S gets most of its sugar from corn and here in Australia we get most of ours from Sugar Cane. I do wonder if these other sorts of sugar use the same process though?
I'm not sure where that info comes from. Maybe it depends where you live, but the sugar everyone I know uses is C&H Sugar. It's Pure Cane Sugar grown in California (C) and Hawaii (H). There's a brand called Domino that is said to be made from a sugar beet/cane mix, but what I've seen is their "gold sugar" made from pure cane sugar and it says it's gold because it's not as processed as white sugar. However, you can use it exactly the same way. But, yeah, this info isn't really correct, at least where I live (California)
Yeap, glad I stopped eating sugar long time ago. I am on Keto - zero sugars and zero carbohydrates. Is my way of living. I feel healthier and happier.
What types of food do you eat?
i also stopped eating any added sugars, though i still have food like lentils and fruit on occasion since my metabolism can tolerate it. it's been a freeing experience, minus the part where 70% of the supermarket is useless to me
Very hard 🤔❣️
This wasn’t very explanatory,was it?
Does they add any kind of animal bones through it?
Yes, it's full of them...
What the hell is a beet???
Overliming!
They take out the rhythm, of course
It’s horrible, it’s just crystallized and isolated sugar
so the spinning makes it white? o-o
Ah this helps me understand my intolerance to sugar cane but weirdly not white sugar.
Intolerance to sugar cane?! haha. You should do yourself a huge favour and watch some Durianrider!!
You know you're watching a bri ish show when they mention tea making as an example for brewing
3:00 and we're left with pure white crystal meth
Stay blessed and happy IN JESUS NAME
Why are sugar beats,corn and cane the number 1 sources of sugar? You can work out sugar of almost anything,,,isn't there anything that is just as easy to grow or process,,I recently tastes coconut sugar it has an interasting twist to it
Date sugar also
Terrifying. No nutrients, no fibre, just deliciously toxic, sweet cancer. Eating the sugar beet in its natural form would've been more wholesome.

Many manufacturers also use the charred bones of animals to further whiten granulated sugar. It's not listed as an ingredient because it is used for processing only. If you're vegan, then consider using only raw sugar, turbinado sugar, or other certified vegan sugar.
Vegan here. That is exactly why i was watching this. I didnt' know this! :(
i would like a source for the animal bones used.
The charred bones of animals are not used in british made sugar ?
Because it's right 😎
I want brown or black sugar the important thing is natural
imagine if the salt of the sea was sugar instead.
😂❤I work for a sugar producer
Seems to have a fairly large carbon footprint just to produce something that gives you a fatty liver.
hi i am sai
hello sai
HA! They changed the title from 'Why is sugar so white?".
They won't answer that question
Until now I thought sugar was made out of sugar cane .
Tropical areas tend to use sugar cane, more temperate regions use sugar beet. All depends on which plants grow best where you are and how much sugar you want to make locally rather than importing.
Was difficult to understand the accent of the host.. :(
is he aiming this for his 5 year old friends?
those machines are so dirty
stop eating sugar
So, they basically add chalk to sugar. & that’s what we eat. Cool.
Did you not get the bit where they filter the chalk out?
@@ChrisHow well i got the bit where they filter the chalk out but how? They only say that so people don't think they're eating chalk! So I'm with Daltira, chalk is basically what gives sugar its whiteness!! I mean, they even use ttianium dioxide as a food colouring especially to whiten icing on cakes!!
@@ChrisHow additionally if all of the chalk was filtered out what then makes the sugar white?
@@PeterPete CHALK IS NOT SOLUBLE. If your sugar contained chalk, your coffee would be gritty.
@@ChrisHow you've not answered my question chris - if all the chalk (CaCO3) is filtered out what makes the sugar white?
In my opinion a solution of limewater is added to the sugar syrup and co2 is bubbled through to whiten the product.
If you think I'm wrong explain to me what causes the sugar to turn white?
Jimmy is pretty sweet too I might say 😻
.~.
Who’s here cos of a lesson I am
WOW! It is a drug white sugar is processed just like cocaine!!!
Would it be fair to say that refined sugar is better quality that raw sugar since the impurities are removed ? Thank you !
What about animal charcoal 😁😁
i think they use bone char (animal charcoal) to filter the sugar very much like filtering water!
But white sugar is bad for us
Poor camera work and very poor editing.
That's cocaine bro .
ah so that's why sugar is white - the presence of chalk or more specifically calcium hydroxide!!
Huh?? How did you reach that conclusion? Something has to give sugar its white colour because it's not naturally white. The source material for any sugar is coloured brownish so why is white sugar, that is made from a brownish substance, white?
There has to be an additive and the only additive that is added to the sugar that is white is lime/chalk. Bubble this through CO2 one will turn the lime into calcium carbonate which is also white.
So next time you add a teaspoon of sugar into your drink, remember you're eating chalk 👍
I've often wondered why white sugar smells smoky 🤣🤣🤣

Learning about sugar and we have racist comedians in the comment section, minus the comedy. So just racists. You kids need a smack then a hug and then, some wise words. Parenting 101
Avoid Chemically processed white anything
John Jeffry So cows milk?
Is it true sugar increase Brain activity. Or just another myth ?
Digvijay Patil good question!
The brain uses sugar, but that doesn't mean you need to eat refined sugars.
Your guts extract sugar from all foods.
Refined sugars only damage your health (& brain).
Our brain (as well as other parts of our body) doesn't use pure sugar to get energy, it takes any kind of carbohydrates and transforms them into glucose and uses that. It's still sugar but a bit different.
Sugar is mostly glucose there genius. Our bodies don't break glucose down into glucose.
The question I always ask is why the hell we even use that trash when brown sugar taste better in every scenario. Put that in your coffee instead!
id rather use stevia or sucrose. Much more sweet imo and doesnt add sugar to your blood. Much better than sugar if you usually have a cup of milk tea near you while you work.
same, I drink a lot of Zevia soda and sucralose energy drinks and don't put sugar in my coffee. But when I do, I make sure it's brown or confectioners lol
"id rather use stevia or sucrose" White sugar is sucrose.
Darren Marsh
I mean sucralose. My bad.
Wait ....
Isn't sugar made from sugar cane??
Not this one.
Only 17%!?
There has to be a more efficient source for monosaccharides.
Human poison factory
Here is the reason why we have epidemic diseases like diabetes and cancer
Gross
Why does it got to be a white thing? 😡
Sugars are really really bad.
Sugar is what poor people eat.
Nowadays, yes.
But sugar is expensive....
Sugars aren't nearly as expensive as they used to be buddy.
FaithIsHere no....sugar and refined carbs in general are actually super cheap compared to protein, fat, and veggies.
Lmao
Because of privilege
