In this episode of Protein Production Technology International, host Nick speaks with Dr. Sirli Rosenvald, Director of Food Science at TFTAK, about the evolving role of fermentation in sustainable food innovation. Dr. Rosenvald explains that fermentation is increasingly recognized as a tool to make food systems more efficient, helping extract more nutrients from resources while reducing waste and environmental impact. She highlights its potential to strengthen resilience in supply chains amid climate change and other disruptions. Many still associate fermentation with traditional foods, so education is key to exploring its broader possibilities. Dr. Rosenvald emphasizes that the diversity of microorganisms offers untapped opportunities to enhance food functionality, including improving solubility, water retention, and nutrient accessibility. The discussion provides insight into how scientific research is being translated into practical solutions that support sustainability and innovation in food production.
