Abstract

PHYSICAL AND COMPRESSIONAL PROPERTIES OF STARCH AND TABLETS OF IRISH POTATO (SOLANUM TUBEROSUM) FLOUR

Oluwagbenle Henry Niyi*, Olatunya Ayomadewa Mercy and Solarin OT

ABSTRACT

The compressional characteristics of native starch of Irish potato (Solanum tuberosum) and the mechanical properties of its tablets were investigated. Compressional characteristics were determined using Heckel and Kawakita equations/plots and density measurement. The starch exhibited good densification during die filling at low pressure and also had high moisture content of 10.5g/100g. The low value of Hausner’s ratio indicated better flowability. The values obtained for the mean particle diameter, particle density and bulk density were: 0.048 mm, 1.78 g/cm3 and 0.63 g/cm3 respectively. The results of the friability test on the tablets indicated that the tablets had better resistance to shock, friction and abrasion.

Keywords: Physical, Compressional, Starch, Tablets, Irish potato.
