Glassy-Rubbery Transition and Recrystallization during Aging of Wheat Starch Gels
1Food Science Department, University of Massachusetts, Amherst, Massachusetts 01003.
Abstract:
Dynamic mechanical analysis (DMA) data indicated an increase in final glass transition temperature with storage time, with no increase in initial temperature. After deconvolution, the tan delta(T) curve for ice melting was identified as the main peak, whereas glassy-rubbery transition peak(s) occurred at lower temperatures. Accompanying increase in "unfreezable" water and degree of amylopectin recrystallization showed that increase in the glassy-rubbery transition involved more than just moisture loss, and it may be possible that some amorphous network may have progressed extensively.

Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
