PROXIMATE COMPOSITION, PHYSICOCHEMICAL AND PASTING PROPERTIES OF A NOVEL AFRICAN STAR APPLE (Chrysophyllum albidum) SEED NUT STARCH AS SUPPLEMENT TO INDUSTRIAL STARCH.
Abstract
Starch are often being sourced from tuber and grains/cereals of crops. African Star Apple (Chrysophyllum albidum) is an unconventional source of starch. Starch isolated from the seed nut after the seeds has been dehulled were analysed for their proximate composition, physicochemical and pasting properties. Chrysophyllum albidum kernel starch contained 16.32% moisture, 0.17% ash , 7.01% protein, 0.01% fat  and 15.85% amylose. Swelling power and solubility of the starch increased with increase in temperature. The bulk densities (loose and tapped) were 0.484 g/ml and 0.617 g/ml respectively. The least gelation studies revealed that the starch gelled at 6%. The Rapid Viscosity Analysis revealed that the starch has high peak and final viscosities. African star apple kernel starch could be an alternative novel source of starch thereby reducing the over reliance on the normal conventional starch sources for applications in food, paper, pharmaceutical and other industries. Key words: African Star Apple, Chrysophyllum albidum, Proximate composition, physicochemical properties.ÂDownloads
