Natural Method Boosts Vitamin B2 Production, Could Aid Developing Nations
Updated June 18, 2025
Researchers at the Technical University of denmark (DTU) have developed a simple, natural method for producing vitamin B2, also known as riboflavin. This innovation involves gently heating lactic acid bacteria, offering a potential solution too vitamin B2 deficiency, a significant health issue in many developing countries. The new method allows for direct fortification of foods with vitamin B2, a crucial nutrient, in local kitchens.
Current industrial vitamin production typically relies on synthetic processes or microorganisms not approved for food use. These methods necessitate complex and costly purification to separate the vitamin from non-food-grade materials. The DTU team’s approach offers a cost-effective and environmentally friendly alternative.
The researchers found that a food-approved lactic acid bacterium can produce significant quantities of vitamin B2 when exposed to heat. this eliminates the need for genetic modification and reduces the use of energy and chemicals compared to traditional methods. The process requires only basic fermentation tools, already common in many households.
Christian Solem, an associate professor at DTU National Food Institute, led the research. “I think it’s lovely that somthing as simple as gentle heating and lactic acid bacteria can be used to produce vitamin B2,” Solem said. “The method allows for food to be fortified with vitamin B2 in an easy way, for example, during the production of yoghurt or sourdough.”
Vitamin B2 is vital for energy production, immune function, and iron absorption. Deficiency can lead to various health problems. This new method integrates vitamin production directly into food fermentation, enabling local vitamin production and addition. By using riboflavin-producing bacteria,manufacturers can improve the nutritional value of traditional foods,enhancing public health while minimizing environmental impact. The key is oxidative stress.
The team subjected *Lactococcus lactis*, a bacterium commonly found in cheese and cultured milk, to temperatures of 38-39°C. Solem explained that this heat induced oxidative stress, prompting the bacteria to produce vitamin B2 as a defense mechanism. By optimizing the process with added nutrients, the researchers achieved a production level of 65 milligrams of vitamin B2 per liter of fermented substrate—nearly 60 times the daily human requirement.
Solem envisions packaging these B2-producing lactic acid bacteria as a starter culture for fermenting foods like milk, maize, or cassava. This would automatically produce riboflavin while preserving the food’s traditional flavor and texture. Many developing countries already have strong traditions of food fermentation, which extends shelf life and reduces waste.
What’s next
The researchers believe this method could be expanded to produce other essential vitamins and nutrients, such as folic acid (B9) and vitamin B12, often lacking in plant-based diets.It could also be applied to various food types, including sauerkraut, further enhancing its potential impact on global nutrition and health.
