Preparation of V‐Type Porous Starch With High Oil‐Adsorption Capacity via Ethanolic Hydrochloric Acid Hydrolysis of V‐Type Granular Starch

V‐type porous starch exhibiting exceptional oil‐adsorption capacity was prepared via rapid ethanolic hydrochloric acid (HCl) hydrolysis of V‐type granular starch. X‐ray diffraction confirmed preferential removal of amorphous regions, resulting in progressive increases in V‐type relative crystallinity. At 0.5% HCl, extending hydrolysis from 10 to 30 min gradually elevated oil uptake from 158.64% to 226.49% while retaining granule contours. For 1.0% HCl, maximal adsorption (358.80%) and specific surface area (45.67 m 2 /g) were achieved within 10 min; continued hydrolysis to 20 min reduced both parameters; after 30 min, near‐peak uptake (348.59%) was restored with the highest V‐type crystallinity. SEM corroborated these trends: 10 min preserved granules, 20 min induced collapse, and 30 min produced fragments with a loosely and uniformly porous structure. Granule integrity is dispensable; performance is governed synergistically by high specific surface area and hydrophobic V‐type single helical cavities.
