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.

I'm curious about the nutritious value and in particular the cholesterol levels of this product. I suppose since it is indistinguishable from butter, it should be the same. Margarine 2.0

[–] Iceblade02@lemmy.world 8 points 1 day ago (2 children)

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.

[–] Soup@lemmy.world 5 points 1 day ago

“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.

[–] drmoose@lemmy.world 1 points 1 day ago

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

[–] Bytemeister@lemmy.world 38 points 2 days ago (1 children)

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

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

[–] mfed1122@discuss.tchncs.de 35 points 2 days 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

[–] sunbytes@lemmy.world 1 points 3 hours ago

I'm watching you, Dent

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 2 days 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.

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 15 points 2 days 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.

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

Also, a

proprietary process

Ugh, capitalism

[–] john_lemmy@slrpnk.net 89 points 3 days ago (3 children)

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

The basic process is not proprietary. It's just the Fischer-Tropsch process. It's been in use since WWII. It produces hydrocarbon chains of arbitrary length from whatever hydrocarbon feedstock you can provide.

Dietary fats are just certain short-chained hydrocarbons accompanied by certain flavorful compounds.

The "proprietary" part is what chemicals they add to the synthesized fat to make it sufficiently comparable to butter.

The Nazis used the same basic process to produce "butter" from coal feedstocks about 90 years ago. This is nothing new.

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

[–] Rivalarrival@lemmy.today 83 points 3 days ago (2 children)

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.

[–] drmoose@lemmy.world 31 points 3 days ago (1 children)

You frame it like it's a bad thing but even if the process is mostly the same isn't that good? Also we can clearly improve on a 100 year old technology even if it's "solved".

[–] Rivalarrival@lemmy.today 72 points 3 days ago

My primary issue is that the entire article is somewhat deceitful. They use phrases like "never seen before", "unprecedented", "pioneering", but those characteristics do not really apply to the +90-year-old technology. The only significant part of the "process" that is different from what was uses in WWII is the specific flavor packs they add to the product.

Their deceitful comments about the technology have me questioning the veracity of the rest of their claims.

Don't get me wrong: I think that Fischer-Tropsch is one of a few important technologies we need to be adopting. The reason we need to adopt it is because it is incredibly energy intensive, but not necessarily time critical. It can provide a profitable sink for excess solar energy production during long summer days, to produce hydrocarbon fuels for the transportation and aviation industries, yet switch offline overnight, overwinter, and during inclement weather, when solar can't meet demand.

But we just don't consume enough butter for this application to be useful to solar generation.

The Air Force experimented with Fischer-Tropsch "SynFuels" about 15 years ago. They actually certified most/all military aircraft to burn SynFuels, to lessen our military's reliance on foreign oil.

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.

[–] No1@aussie.zone 2 points 1 day ago* (last edited 1 day ago)

I shall add some potassium and market it as buttOCK

[–] waterSticksToMyBalls@lemmy.world 14 points 2 days ago (1 children)

I can't believe it's not butter

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 3 days ago (19 children)

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

Just a hydrogen atom away from being plastic.

So, can we turn the garbage patch into butter?

[–] Saleh@feddit.org 22 points 3 days ago* (last edited 3 days ago) (1 children)

I would like to see the LCA analysis on this one. I would not be surprised if this ends up using energy causing more damage than the damage that dairy farming methane and land conversion is doing.

[–] surewhynotlem@lemmy.world 23 points 3 days ago (7 children)

I'd be very impressed if this somehow created more methane than cow farts.
