Physicochemical, thermal and structural properties of heat moisture treated common buckwheat starches.

ABSTRACT: Common buckwheat starch modified by heat moisture treatment at different temperatures was analysed for functional, pasting, structural, thermal, gel textural and morphological properties. Heat moisture treatment decreased swelling power, solubility and oil absorption capacity while amplified water absorption capacity of buckwheat starch. Lower whiteness index with higher a* and b* values were observed for treated starches. Modified starches showed increased paste clarity and reduced syneresis. A declining order of paste clarity and freeze-thaw stability of native and treated starches was noticed during storage period. RVA analysis showed reduced viscosities (peak, trough, breakdown, final and setback viscosity) for hydrothermally treated starches. Increased gel hardness was observed for mo
