Sudan grass (Sorghum sudanense (Piper) Stapf.) is an underutilized cereal with great potential as an alternative starch source for food and non-food applications. This study evaluated the physicochemical, structural, tech- nological, and nutritional properties of starch from Sudan grass. Starch extraction was carried out using four distinct methods: aqueous extraction with H₂O (WE), reductive extraction with SO₂ (RE), alkaline extraction with 1 N NaOH (AE), and combined extraction with SO₂ + 0.1 N NaOH (CE).The extracted starches exhibited high amylose content (35.18–38.04 %), monomodal granules with A-type crystallinity, and low enzymatic hydrolysis rates, contributing to their high resistant starch content (>28 %). The CE method yielded the highest starch recovery (41.67 %) due to the synergistic action of SO₂ and NaOH in protein and lipid removal. The RE method resulted in the highest level of starch damage (7.14 %), impacting pasting properties. Thermal and rheological analyses indicated high gelatinization temperatures (80.27 ◦C – 86.75 ◦C), significant gel elasticity, and pseu- doplastic behavior, attributes that suggest potential applications in biodegradable film production. Sudan grass starch also exhibited a high phenolic compound content (up to 2136 mg GAE/100 g for RE), which, along with its amylose content, could have contributed to its reduced enzymatic hydrolysis rate and suitability for low glycemic index applications. Overall, these findings highlight the potential of Sudan grass starch as a promising novel source for food and non-food applications.
