Large-scale biotransformation of whole rye grains: how processing-driven microstructural and biochemical changes shape macronutrient digestion and mineral bioaccessibility

Diego Herrero, Elena Peñas, Juana Francisca Frias, Pieter Heirbaut et autres

Rye is nutritionally dense, yet its utilisation is constrained by antinutrients and structural features that limit nutrient release. This study applied an industrial soaking–germination–fermentation–stabilization process with time-resolved sampling to characterise compositional, microstructural and digestive changes within whole rye. Scanning electron microscopy showed …
