From the characteristics determined with the RVA regarding final viscosity and tendency to retrogradation, it can be assumed that the cakes containing BPSF will have a extended shelf life due to the low retrogradation of the starch present in the final product.

This crumb firming kinetics can be applied to modified Avrami model (7) [85, 87, 92] based on starch retrogradation [87] where [theta] represents the recrystallization still to occur and [T.sub.[infinity]], [T.sub.0], and [T.sub.t] represent the bread hardness at [infinity] time, bread hardness at zero time, and bread hardness at t time, respectively.
The covalently linked carboxymethyl potato starch-whey was characterised by improved thermal stability and reduced retrogradation in comparison to unmodified starch.

In order to prevent retrogradation, some amide-based co-plasticizers such as formamide and acetamide were used (25).
It reduces starch retrogradation after baking and thus provides baked goods with improved and longer-lasting freshness.

The observed loss in structural integrity of the blends in soil with increasing starch content may be linked as an evidence for reduction in molecular weight of starch due to fragmentation during its retrogradation. Again, starch grains on the blend sample before burial are expected to disappear as they are consumed by microorganisms and insects in the soil leaving a blend with a surface full of cavities.
