Sprouting Rye Increases and Protects Folate

Sprouting rye increases its folate content by 1.7- to 3.8-fold, depending on germination temperature, according to researchers in Finland who studied the effects of different processes on this key nutrient. The scientists also found that thermal treatments – including extrusion, puffing, and toasting – resulted in significant folate losses. However, when the rye was germinated (sprouted) first and then heat-processed, losses were minimized, showing sprouting to be a useful potential tool in safeguarding nutrients during food processing.
