Physical properties of dehusked and debranned selected Indian millets

Abstract

The impact of milling on the physical attributes of Indian minor millets, namely foxtail, little, kodo, barnyard and proso millets are examined in the present study. Dehusking and debranning processes led to a reduced 1000 kernel weight and volume but increased bulk and true density. Hardness varied significantly between all millets in all forms. Different millets differ in properties such as length, breadth, thickness, equivalent diameter, geometric mean diameter, arithmetic mean diameter, aspect ratio, surface area and sphericity in native, dehusked and debranned forms. Understanding these variations can aid in the design of storage, transportation and new millet processing machinery.
