Key Takeaways
- Researchers at UC Davis are partnering with California Cultured to develop affordable and sustainable chocolate production using plant cell technology.
- The cocoa industry faces serious challenges, with climate change threatening up to 50% of cocoa-growing regions in the Ivory Coast by 2060.
- California Cultured aims to commercialize cultured chocolate by 2027, minimizing environmental impacts associated with traditional cacao farming.
Innovative Chocolate Production
Scientists at the University of California, Davis are collaborating with Sacramento-based California Cultured to revolutionize chocolate production through plant cell cultivation. According to a 2024 National Confectioners Association report, 65% of U.S. consumers purchase chocolate, contributing to $21.4 billion in sales expected to increase to $37.6 billion by 2029. This surge contrasts sharply with the challenges facing cacao farming.
Cacao trees, primarily grown in the Ivory Coast, are experiencing drastic declines due to climate change impacts such as extreme heat, erratic rainfall, and shifting weather patterns. A 2025 study estimates that by 2060, up to half of current cacao-growing areas may be unsuitable for cultivation, risking both yields and livelihoods. To combat these issues, California Cultured proposes “cultured chocolate,” produced in bioreactors, as a sustainable alternative that circumvents the traditional cacao farming challenges, including deforestation and child labor.
Vice President of Science and Technology at California Cultured, Steve Lang, emphasizes the potential of bioreactor-grown chocolate to mimic the authentic product without its environmental downsides. With support from the National Science Foundation and BioMADE, UC Davis researchers are focusing on optimizing bioreactor designs, which will help lower costs associated with this innovative food production method.
The rise of cellular food technologies lends itself to producing not just chocolate but also coffee, berries, and more. Plant cell suspension culture, a form of this technology, allows edible cells to be generated without the conventional agricultural risks. Distinguished professor Karen McDonald believes this method is poised to become a key production platform in the evolving landscape of cellular agriculture, which is emerging alongside discussions of cultivated meat and plant-based proteins.
Plant cell cultures utilize dedifferentiated cells and small aquatic plants, cultivated in sterile liquid media without the need for sunlight. These cells can be maintained in dark environments and use simple growth nutrients, effectively avoiding traditional agricultural hazards. Moreover, they circumvent inefficiencies associated with harvesting whole plants, as they can convert sugars into food products without discarding any parts.
Despite the promise of plant cell technology, there are hurdles to overcome. Traditional bioreactors are expensive, but California Cultured has developed cost-effective alternatives suited for plant cell growth. The collaboration with UC Davis will enhance prototype validation, cleaning processes, and commercial viability assessments. Current efforts have proven successful in large-scale bioreactor cultivation of Theobromo cacao cells, with plans for early commercial production of cocoa powder by 2027, responding to growing industry demands.
