Description
Dual-process fermentation and alkalization technique that increases bioavailable nutrients in millet.
Technical
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%.
Culinary Significance
Essential step for making tuwo masara (millet porridge), reducing bitterness while improving mineral absorption.
