Climate change is stressing rainforests where the highly sensitive cocoa bean grows, but chocolate lovers need not despair, say companies that are researching other ways to grow cocoa or develop cocoa substitutes.
Scientists and entrepreneurs are working on ways to make more cocoa that stretch well beyond the tropics, from Northern California to Israel, The Associated Press said.
California Cultured, a plant cell culture company, is growing cocoa from cell cultures at a facility in West Sacramento, California, with plans to start selling its products next year. It puts cocoa bean cells in a vat with sugar water so they reproduce quickly and reach maturity in a week rather than the six to eight months a traditional harvest takes, said Alan Perlstein, the company's chief executive. The process also no longer requires as much water or arduous labor.
“We see just the demand of chocolate monstrously outstripping what is going to be available,” Perlstein said. “There's really no other way that we see that the world could significantly increase the supply of cocoa or still keep it at affordable levels without extensive either environmental degradation or some significant other cost.”
Cocoa trees grow about 20 degrees north and south of the equator in regions with warm weather and abundant rain, including West Africa and South America. Climate change is expected to dry out the land under the additional heat. So scientists, entrepreneurs and chocolate-lovers are coming up with ways to grow cocoa and make the crop more resilient and more resistant to pests — as well as craft chocolatey-tasting cocoa alternatives to meet demand.
The market for chocolate is massive with sales in the United States surpassing $25 billion in 2023, according to the National Confectioners Association. Many entrepreneurs are betting on demand growing faster than the supply of cocoa. Companies are looking at either bolstering the supply with cell-based cocoa or offering alternatives made from products ranging from oats to carob that are roasted and flavored to produce a chocolatey taste for chips or filling.
The price of cocoa soared earlier this year because of demand and troubles with the crop in West Africa due to plant disease and changes in weather. The region produces the bulk of the world’s cocoa.
“All of this contributes to a potential instability in supply, so it is attractive to these lab-grown or cocoa substitute companies to think of ways to replace that ingredient that we know of as chocolatey-flavored,” said Carla D. Martin, executive director of the Fine Cacao and Chocolate Institute and a lecturer in African and African American Studies at Harvard University.
The innovation is largely driven by demand for chocolate in the US and Europe, Martin said. While three-quarters of the world's cocoa is grown in West and Central Africa, only 4% is consumed there, she said.
The push to produce cocoa indoors in the US comes after other products, such as chicken meat, have already been grown in labs. It also comes as supermarket shelves fill with evolving snack options — something that developers of cocoa alternatives say shows people are ready to try what looks and tastes like a chocolate chip cookie even if the chip contains a cocoa substitute.
They said they also are hoping to tap into rising consciousness among consumers about where their food comes from and what it takes to grow it, particularly the use of child labor in the cocoa industry.
Planet A Foods in Planegg, Germany, contends the taste of mass market chocolate is derived largely from the fermentation and roasting in making it, not the cocoa bean itself. The company's founders tested out ingredients ranging from olives to seaweed and settled on a mix of oats and sunflower seeds as the best tasting chocolate alternative, said Jessica Karch, a company spokesperson. They called it “ChoViva” and it can be subbed into baked goods, she said.
“The idea is not to replace the high quality, 80% dark chocolate, but really to have a lot of different products in the mass market,” Karch said.
Yet while some are seeking to create alternative cocoa sources and substitutes, others are trying to bolster the supply of cocoa where it naturally grows. Mars, which makes M&Ms and Snickers, has a research facility at University of California, Davis aimed at making cocoa plants more resilient, said Joanna Hwu, the company's senior director of cocoa plant science. The facility hosts a living collection of cocoa trees so scientists can study what makes them disease-resistant to help farmers in producing countries and ensure a stable supply of beans.
“We see it as an opportunity, and our responsibility,” Hwu said.
In Israel, efforts to expand the supply of cocoa are also underway. Celleste Bio is taking cocoa bean cells and growing them indoors to produce cocoa powder and cocoa butter, said co-founder Hanne Volpin. In a few years, the company expects to be able to produce cocoa regardless of the impact of climate change and disease — an effort that has drawn interest from Mondelez, the maker of Cadbury chocolate.
“We only have a small field, but eventually, we will have a farm of bioreactors,” Volpin said.
That's similar to the effort under way at California Cultured, which plans to seek permission from the US Food and Drug Administration to call its product chocolate, because, according to Perlstein, that's what it is.
It might wind up being called brewery chocolate, or local chocolate, but chocolate no less, he said, because it's genetically identical though not harvested from a tree.
“We basically see that we're growing cocoa — just in a different way,” Perlstein said.

French Scientists Find New Blood Type in Guadeloupe Woman

A French woman from the Caribbean island of Guadeloupe has been identified as the only known carrier of a new blood type, dubbed "Gwada negative," France's blood supply agency has announced.

The announcement was made 15 years after researchers received a blood sample from a patient who was undergoing routine tests ahead of surgery, the French Blood Establishment (EFS) said on Friday.

"The EFS has just discovered the 48th blood group system in the world!" the agency said in a statement on social network LinkedIn.

"This discovery was officially recognized in early June in Milan by the International Society of Blood Transfusion (ISBT)."

The scientific association had until now recognized 47 blood group systems.

Thierry Peyrard, a medical biologist at the EFS involved in the discovery, told AFP that a "very unusual" antibody was first found in the patient in 2011.

However, resources at the time did not allow for further research, he added.

Scientists were finally able to unravel the mystery in 2019 thanks to "high-throughput DNA sequencing", which highlighted a genetic mutation, Peyrard said.

The patient, who was 54 at the time and lived in Paris, was undergoing routine tests before surgery when the unknown antibody was detected, Peyrard said.

This woman "is undoubtedly the only known case in the world," said the expert.

"She is the only person in the world who is compatible with herself," he said.

Peyrard said the woman inherited the blood type from her father and mother, who each had the mutated gene.

The name "Gwada negative", which refers to the patient's origins and "sounds good in all languages", has been popular with the experts, said Peyrard.

The ABO blood group system was first discovered in the early 1900s. Thanks to DNA sequencing, the discovery of new blood groups has accelerated in recent years.

Peyrard and colleagues are now hoping to find other people with the same blood group.

"Discovering new blood groups means offering patients with rare blood types a better level of care," the EFS said.
