Abstract
Pearl millet was subjected to air plasma bubbling along with soaking to enhance HCl extractable iron by reducing phytic acid content. The pearl millet was soaked for 11 h and 10 h followed by plasma bubbling (1 and 2 h) at input voltage 180 V and 10 lph flow rate. A 64.9% and 70.93% of reduction in phytic acid was observed with treatments. The total iron content was reduced while HCl extractable iron content improved by 68% and 59% with 1 h and 2 h exposure time. The significant changes (p≤ 0.05) in pearl millet’s physical, nutritional, and techno-functional properties were noticed with plasma exposure. The present study shows the potential of plasma exposure along with soaking for reducing phytic acid content, improving free iron, and ameliorating techno-functional properties of pearl millet.
