Physicochemical and microstructural characteristics of Frafra potato (<i>Solenostemon rotundifolius</i>) starch

Frafra potato (Solenostemon rotundifolius) is an underutilized climate-resilient tuber crop commonly cultivated in the tropics. Different accessions have been identified and bred to broaden its application food. This study characterized starches extracted from ten accessions, Ghana (released) Burkina Faso (unreleased), terms of yield, physicochemical, microstructural characteristics. The did not differ significantly (p < .05) color (L*) amount (35 39% dry matter basis). Furthermore, there were no significant differences among them amylose/amylopectin ratio, syneresis %, granule types shapes, except for one unreleased (E82), which had a smaller size. There were, however, paste clarity starch gels, ranging 51 63% as well thermal properties starches. XRD FTIR spectra showed be A-type, typical starches, with relative crystallinities between 30.5 33.5%. cultivars clustered into two groups using PCA procedures; group (Maa-Lana Nutsugah) clustering on starch, while other (E82, E111, E132, E134, E145, Manga, Naachem-Tiir, WAAPP) change temperature. variations size characteristics could impact performance, cooking textural properties, these food applications.
