In an innovative approach to enhancing the nutritional content of alternative dairy products, a recent study focuses on the “riboflavin-enriched plant-based” beverages, using a specialized strain of lactic acid bacteria. The research published by Iñaki Diez-Ozaeta, Irati Berasarte, Ahmed Fouad Zeid, Mercedes Fernández, Pasquale Russo, Paloma López, Mª Teresa Dueñas, and Mari Luz Mohedano, explores the potential of the riboflavin-overproducing and dextran-producing Weissella cibaria BAL3C-5 C120T strain. This strain has shown remarkable capabilities in fortifying oat-, rice-, soybean-, and almond-based drinks, making a significant stride toward addressing nutritional deficiencies in vegan and vegetarian diets.
Riboflavin, or vitamin B2, is crucial for energy production and cellular function but is notably absent in sufficient quantities in many plant-based diets. Utilizing the Weissella cibaria strain, the researchers conducted fermentation experiments that proved the strain’s ability to substantially enhance the riboflavin content in these beverages. Notably, the oat-based drink achieved an increase in riboflavin levels up to 3.4 mg/L after just 24 hours of fermentation. This process not only boosts the vitamin content but also enhances the drink’s texture through dextran production, offering a gel-like consistency that mimics the mouthfeel of traditional dairy products.
In addition to riboflavin fortification, the study also highlighted the potential of the fermented beverages to act as carriers for probiotics. The strain evidenced excellent viability and a promising pH-lowering ability, making it a robust candidate for sustaining beneficial gut bacteria when consumed. The enhanced production of panose, a prebiotic oligosaccharide, further underlines the dual-functionality of the beverages as both nutrient-rich and gut health-promoting.
This groundbreaking research signifies a pivotal advancement in the field of functional foods, particularly in the developing niche of riboflavin-enriched plant-based beverages.
