OT: Lab-grown chocolate culture

I’m currently reading the book, “Eating to Extinction” about the loss of food diversity around the world.

In some cases the loss of food diversity is because the food was literally hunted to near-extinction, such as the buffalo or the Olympia oysters or the collapse of fisheries on the east and west coasts.

In other cases the loss of food diversity was because breeders (including scientists) developed breeds that were so superior to the original that the new, enhanced breed was planted or grown in worldwide monocultures which led to the loss of multitudes of diverse (though inferior) local varieties. One example is the Holstein cow which produces double the milk of the older varieties. Another example is specific microorganisms, such as particular strains of yeast or lactobacillus, that produce fermented products such as cheeses. There are companies that specialize in producing and shipping these micro-organisms.

Scientists have now discovered the specific cultures that produce superior-tasting chocolate.

Scientists Have Unlocked the Secret That Gives Fine Chocolate Its Great Taste

The breakthrough could help farmers standardize their product

By Nidhi Subbaraman, The Wall Street Journal

What’s the secret to the best-tasting chocolate?

It is using the right microbes, and for the first time scientists have isolated a collection of those bugs and made a superior-tasting chocolate in a laboratory.

Chocolate, like sourdough or yogurt, begins with fermentation. Farmers stash cocoa beans scooped out of ripe cocoa pods in wooden boxes outdoors, cover them with leaves and leave them alone for a week. Fermentation is kicked off by bacteria and yeasts that live in the boxes or the soil….

Through a genetic analysis, the scientists zeroed in on the hundreds of microbes that were present throughout fermentation. They narrowed the list to species that were able to produce chemicals found in fully-fermented chocolate, and used a starter culture made of nine species to ferment beans in the lab.

“Lo and behold, they tasted like fine-flavor cocoa,” the kind used in more expensive chocolate. … [end quote]

Fine-flavor cocoa is sourced from Colombia and Madagascar. “Bulk cocoa” which doesn’t taste as fruity, caramel and floral is produced in countries such as Ghana.

If I was a commercial producer of microbial cultures I would be all over this information like white on rice. What an opportunity to provide uniform great-tasting bacterial cultures for cocoa instead of the current unpredictable local microbes.

The buffalo was not hunted to extinction for food but to deny food to unwanted people.

Does the book mention that now scientists can clone animals (and plant)?

Not to pick a nit, but the buffalo isn’t extinct.

Came close.

American Bison, not buffalo.

And it is important to note that after near extinction they are now resurging and being used intensively for their potent role in ecological restoration on the plains.

Kudos to Captain for pointing out that their slaughter was a crux hidden part of genocidal policies against the great plains aboriginal tribes, and the slaughter of the once great herds one of the ugliest hidden parts of USAian history.

Some people can’t tell the difference between bison and cattle.

My nephew was driving home from a collage class, and he noticed a car pulled over on the side of the highway. A woman and several small children were standing outside of the car, so he pulled over to see if they needed help. The car had New York plates. The woman said no, they had pulled over because her children had never seen buffalo before. My nephew looked at the adjacent pasture. Nothing there but a large herd of Black Angus. He just smiled and said ok.

They tell us extinction of mammoths and many large animals occurred soon after the arrival of humans. The animals were defenseless against human hunting methods. They were soon hunted to extinction. Again and again.

Yeah but will it offer the same health benefits of the plant based chocolate?

I read the article to report they are optimizing the microorganisms that ferment the beans. Incorporating a gene sequence to raise chocolate in a deep fermentation tank probably from e coli was not claimed, but someone must be working on it. Especially with rising chocolate prices might be an interesting investment. Yes, will it have good flavor!!

All well and good, but no benefit if there is nothing to ferment. Mars is working on that and I wonder if the non-GMO crowd are chocolate lovers.
