What You Need to Know
Lactic acid bacteria (Lactobacillus spp.) ferment millet carbohydrates, while potassium carbonate from ash raises pH to degrade phytic acid. This combined process increases iron (Fe2+) and zinc solubility by 40-60%.
Essential step for making tuwo masara (millet porridge), reducing bitterness while improving mineral absorption.
