A California-based biotechnology startup has officially launched the world's first commercially available butter made entirely from carbon dioxide, hydrogen, and oxygen, eliminating the need for traditional agriculture or animal farming. Savor, backed by Microsoft co-founder Bill Gates through his Breakthrough Energy Ventures fund, announced the commercial release of its animal- and plant-free butter after three years of development.

The revolutionary product uses a proprietary thermochemical process that transforms carbon dioxide captured from the air, hydrogen from water, and methane into fat molecules chemically identical to those found in dairy butter. According to the company, the process creates fatty acids by heating these gases under controlled temperature and pressure conditions, then combining them with glycerol to form triglycerides.

Whilst yes, uplifting, I also have a certain inherent skepticism to artificial facsimiles. Too often it's an unwelcome discovery.

For instance about a year ago we found a new product in the cheese aisle, slightly cheaper than regular gouda and called "gaudina" - turns out, not actually cheese but instead made from milk powder, palm oil and other assorted stuff.

Until somebody proves through proper trials and reviews that the products have no statistically significant difference in health outcomes, I'll be hesitant.

“Other assorted stuff”? The palm oil probably isn’t great, of course it’s simple existence is causing the intentional destruction of important forests and it, and the people who use it, can fuck right off, but otherwise I dunno, that doesn’t sound like the end of the world.

I think health on cheese a pretty low bar to beat tho

...carbon dioxide, hydrogen, and oxygen...

Pretty sure that is what regular butter is made out of too.

[–] mfed1122@discuss.tchncs.de 33 points 1 day ago

Yes, they aren't trying to make an alternative butter substitute as I understand it. They're trying to make real butter via a purely chemically synthetic process.

“Tastes just like the real thing” is a sure sign that it is almost, but not quite, entirely unlike the real thing

[–] Semi_Hemi_Demigod@lemmy.world 5 points 22 hours ago

That’s what I’m thinking. For example, there are milk proteins in butter that undergo the Maillard reaction to produce different flavors. Will this product have the same proteins?

[–] filcuk@lemmy.zip 10 points 1 day ago

Typically there are minor 'impurities' that make the 'real' thing taste different.
Vanillin, for example, is very easy to produce chemically, which is good, because growing and harvesting it naturally is very difficult, but it's missing a lot of the compounds which add subtle yet important taste and smell to the natural stuff.

Especially tea

[–] RBWells@lemmy.world 35 points 1 day ago (3 children)

How is this not just crisco, hydrogenated fat? Butter seems like it has more going on, traces of milk proteins & sugars that give it flavor.

[–] exasperation@lemmy.dbzer0.com 14 points 1 day ago

Hydrogenated vegetable oils still start with vegetable oil, which have to be extracted from farmed crops (mostly soybeans).

This is a process that skips living feedstock from biological organisms and assembled the fatty acids directly from methane, water, and carbon dioxide. No photosynthesis, no cellular metabolism, nothing like that.

I bet that price is the main issue. The reason all of these startups fall into oblivion is that price is astronomical.

[–] chonglibloodsport@lemmy.world 34 points 1 day ago (3 children)

This isn’t butter, this is one type of butter fat. It’s missing the milk solids, proteins, and other molecules that contribute to butter’s smell and taste.

I shall add some potassium and market it as buttOCK

[–] waterSticksToMyBalls@lemmy.world 14 points 1 day ago (1 children)

I can't believe it's not butter

[–] No_Eponym@lemmy.ca 1 points 1 day ago (2 children)

Maybe they add some of those under "natural flavors"?

Just a hydrogen atom away from being plastic.

[–] Sabata11792@ani.social 8 points 22 hours ago

So, can we turn the garbage patch into butter?

[–] TheLeadenSea@sh.itjust.works 131 points 2 days ago (6 children)

If it's not dairy, is this not margarine rather than butter?

Also, a

proprietary process

Ugh, capitalism

[–] john_lemmy@slrpnk.net 92 points 2 days ago (3 children)

I mean, it was backed by Bill Gates, mr proprietary himself

This isn't new technology. This is the Fischer-Tropsch process, which cracks and/or lengthens hydrocarbon chains to produce molecules of the specifically desired length. The Germans used this same process almost a century ago. They cracked coal to produce lighter chemicals (primarily methane) then re-lengthened those methane chains to produce a variety of products, ranging from fuels, lubricants, and yes: edible "butter".

This article repackages the same technology the Nazis used to feed their U-boat crews in WWII.

[–] exasperation@lemmy.dbzer0.com 1 points 19 hours ago

You're right, but I am curious whether they'll be able to pursue this chemically through non-biological feedstocks. Most existing use of Fischer-Tropsch turns fossil fuels (coal, natural gas) into other types of hydrocarbons.

And they're specifically targeting output of fatty acids, using fractional distillation to separate each fatty acid, and then forming triglycerides according to the characteristics they're looking for.

It all sounds very energy intensive and inefficient, so I'm not sure how they expect to make money doing this, but if they can dial in which fatty acids to assemble into triglycerides I can see this being a good substitute for palm oil and coconut oil, and maybe other vegan substitutes for animal fats like tallow and lard.

Once we kill the Earth, this will be how food is manufactured. I am now going to finish my box of Soylent Green.

[–] Zoomboingding@lemmy.world 22 points 2 days ago (16 children)

I'm not sure why people are so puritanical about this. I think Beyond Burgers and Soylent are great.
