Thanks to a significant breakthrough in understanding cacao bean fermentation, scientists may soon be able to produce consistently delicious chocolate. Similar to how starter cultures revolutionised beer and cheese production, new research in the journal Nature Microbiology could bring a comparable transformation to the chocolate industry.
Researchers at the University of Nottingham have successfully replicated the complex cocoa bean fermentation process in a controlled laboratory setting. Traditionally, this essential step occurs spontaneously on farms, where naturally occurring yeasts and bacteria ferment the beans in large piles. This uncontrolled method results in notable flavour inconsistencies between batches and regions.
The Nottingham team, working with Colombian farmers, first identified the key factors influencing flavour. They discovered that both abiotic factors (such as temperature and pH) and biotic factors (the specific microbial communities) are crucial for flavour development. By pinpointing the microbes responsible for desirable flavours, they created a defined microbial community—a curated mix of bacteria and fungi—capable of replicating the natural fermentation process.
This breakthrough means chocolate makers may soon have a powerful tool to ensure consistent quality and explore new flavour possibilities. With a standardised process, they can reliably produce high-quality chocolate, reducing waste and unpredictability currently affecting the industry. The findings also provide significant benefits to cocoa farmers, enabling them to use measurable markers to produce more valuable, high-quality beans, irrespective of their location. This scientific advancement is set to elevate chocolate from an art form to a science, ensuring a higher standard of quality globally.
