“…[37,38] However, recent studies have established that starch granules of smaller sizes are more amenable to enzymatic hydrolysis due to their larger surface area for enzymatic binding and reaction. [39,40] Investigation of the morphology of the starch granules isolated from the seed accessions of the three species using Scanning Electron Microscopy (×500) revealed similarity in the shape of the starch granules of the accessions of the three species (Figure 5). The microscopic examination showed that most of the granules had shapes which varied from round to oval to bean-shaped.…”

Carbohydrates are significant components of legumes, and their profiling can provide information about their nutritional value and potential health benefits. This study explores the proximate composition and carbohydrate profiles of accessions of three underutilized legumes, namely, Vigna radiata, Vigna mungo, and Macrotyloma uniflorum. The total starch and soluble sugar are determined. Starch granule morphology and diameter are determined using scanning electron microscopy and chain length distribution of amylopectin is analyzed using Capillary Electrophoresis. All accessions of the legumes vary both in their proximate composition and carbohydrate components. Accessions of M. uniflorum (PI‐658594‐01‐SD) have the highest carbohydrate component (7.6%) while V. radiata (TVR‐42) has the least (4.2%). Macrotyloma uniflorum accensions (PI‐658594‐01‐SD, and PI‐180437‐01‐SD) have the highest starch and sucrose contents, while V. mungo accensions (TVM‐13, and TVM‐11) have the lowest. The glucose and fructose contents are lower than sucrose in all the accessions of the legumes. Macrotyloma uniflorum accensions exhibit larger granules while accessions of Vigna species have the smallest granules. All species accessions exhibit similar amylopectin chain length distribution profiles although accessions of V. mungo slightly differ in their proportion of long and short glucan chains. The three species of underutilized legumes exhibit unique characteristics which make them suitable for consumption and may be exploited as a source of nutraceuticals and pharmaceuticals.
