Investigating the glassy to rubbery transition of polydextrose and corn flakes using automatic water vapor sorption instruments, DSC, and texture analysis
… amorphous food system, corn flakes. In addition, textural analysis was conducted in order to relate the mechanical properties of corn flakes to the glassy to rubbery transition results from the thermal method and the automated sorption isotherm methods. The results from corn flakes showed that the …
