Preparation of Starch Solution - Flinn Sci
Webb1 aug. 2024 · Starch treated at 120 °C showed similar molar mass as its native form indicating that treatment at 120 °C had resulted in the disassembly of the starch granules into its macromolecular chains. Reduction in viscosity and particle size was observed with increased temperature from 120 to 150 °C. Starch solution was used as indicator for visualizing the periodic formation and consumption of triiodide intermediate in the Briggs-Rauscher oscillating reaction. The starch, however, changes the kinetics of the reaction steps involving triiodide ion. A 0.3% w/w solution is the standard Visa mer Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by α-(1→4)-D glycosidic bonds.
