Starch refractive index

Webbmore, refractive index yielded estimates of starch solubility that were well related to a commercial lab’s measures of glucose release for samples of flaked corn that were stored for 0 to 48 hours subsequent to flaking. (Key Words: Starch Availability, Steam-Flaked Corn, Refractive Index.) Introduction When grain is steam flaked, the starch WebbRefractive Index. The refractive index (n) ... Some types of starch, known as resistant starch, are also indigestible by human beings and may be analyzed as dietary fiber. The basis of many fiber analysis techniques is therefore to develop a procedure that mimics the processes that occur in the human digestive system.

Webb11 apr. 2024 · The increase of fluence up to 22 J/cm 2 causes a drop in the optical bandgap (E g) values from 5.88 to 5.56 eV when n = 1/2, associated with a rise in the refractive index. We attribute these changes to cross-linking that destroys the ordered regions and thus increases the amorphous phase.
