摘要: Abstract The impact of chestnut starch (CS) roasting temperature and time on the composition, solubility, dextrin content crystallinity degree as well hydrogel forming profiles viscoelastic features was evaluated. Monitoring thermorheological characteristics allowed determining evolution roasted starches in presence (RCS) absence (RCSI) soluble fraction after use different temperatures (from 120 to 220oC). Textural profile analysis (TPA) RCS hydrogels employed determine textural features. largest solubility values were found samples treated at 190oC (RCS190) for 10h, 210oC (RCS210) 10h 220oC (RCS220) 6h. Amylose showed a negative linear relationship. formed with between 170oC exhibited intermediate strength full thermal stable Hydrogels prepared from 190 promoted stronger fully formation. RCS220 presented equivalent strength, but no characteristics. RCSI decreased rising temperature. water syneresis observed aged two weeks room temperature, apart hydrogels. A relationship parameters obtained by TPA determined rheological characterization established.
