Abstract

Starches extracted from selected roots and tubers (white yam, trifoliate yam and sweet potato) were physically and chemically modified through heat moisture treatment (HMT) and acetylation respectively before evaluating their proximate composition and pasting properties for exploitable potentials. Starch sample NSPS (Native starch of sweet potato) significantly (p < 0.05) had highest values in: moisture content (13.40%), protein content (0.58%); and lowest value in carbohydrate content (85.09%). Starch sample NTYS (native starch of trifoliate yam) significantly (p < 0.05) was highest in ash content (0.69%) and fat content (0.52%); whereas starch sample PSPS (heat moisture treated starch of sweet potato) significantly (p < 0.05) made lowest value in fat content (0.21%). Starch sample CWYS (aetylated white yam starch) significantly (p < 0.05) gave highest values in: carbohydrate content (88.41%), pasting temperature (63.08°C), pasting time (6.98 min.); and lowest values in: moisture content (10.45%), ash content (0.44%), protein content (0.30%), peak viscosity (299.22 RVU), trough viscosity (101.99 RVU) and final viscosity (377.55 RVU). Starch sample PWYS (heat moisture treated starch of white yam) significantly (p < 0.05) scored highest value in breakdown viscosity (238.46 RVU) but significantly (p < 0.05) had lowest value in setback viscosity (266.22 RVU). Starch sample NWYS (native starch of white yam) significantly (p < 0.05) took lead-values in peak viscosity (331.88 RVU), trough viscosity (131.11 RVU), final viscosity (403.13 RVU), setback viscosity (277.02 RVU) but significantly (p < 0.05) had lowest values in pasting temperature (59.79°C) and pasting time (6.10 min.). Starch sample CTYS (acetylated trifoliate yam starch) significantly (p < 0.05) had lowest value in breakdown viscosity (174.58 RVU). These results obtained highlighted the huge potentials of these starches in: the formulation of composite flours; and manufacture of confectioneries, salad cream, mayonnaise, texturizing agents, thickeners, stabilizers, fillers, flavouring agents, beverage and bakery products; and industrial energy and time savings.

Starch sample PWYS (heat moisture treated starch of white yam) significantly (p < 0.05) scored highest value in breakdown viscosity (238.46 RVU) but significantly (p < 0.05) had lowest value in setback viscosity (266.22 RVU). Starch sample NWYS (native starch of white yam) significantly (p < 0.05) took lead-values in peak viscosity (331.88 RVU), trough viscosity (131.11 RVU), final viscosity (403.13 RVU), setback viscosity (277.02 RVU) but significantly (p < 0.05) had lowest values in pasting temperature (59.79°C) and pasting time (6.10 min.). Starch sample CTYS (acetylated trifoliate yam starch) significantly (p < 0.05) had lowest value in breakdown viscosity (174.58 RVU). These results obtained highlighted the huge potentials of these starches in: the formulation of composite flours; and manufacture of confectioneries, salad cream, mayonnaise, texturizing agents, thickeners, stabilizers, fillers, flavouring agents, beverage and bakery products; and industrial energy and time savings.
