At low moisture content the process of gelatinization can be better defined as melting of starch (Liuet al.
2009). After microwave vacuum processing the pellets, the
lack of gelatinization endotherm determined by DSC indicates that all starch granules were completely gelatinized or
melted. These findings were independent fromDGprior to
expansion. Donovan (1979) and Wanget al. (1991) found
that for a complete gelatinization of starch a minimum of
14 water molecules are needed to interact with each
anhydroglucose subunit.
