3.6. Influence of storage time on hardness, moisture, and aw
The influence of storage time on cake properties was also
evaluated (data not shown). The addition of E2 was not analysed
because of the increased hardness observed after 24 h.
Hardness increased significantly (P < 0.05) with storage time.
The samples with lipase displayed the lowest hardness values after
7 and 14 days of storage. Stojceska and Ainsworth (2008) reported
that, on one hand, lipases modify the interaction between the flour
lipids and gluten. On the other hand, the increased level of
monoglycerides that forms the amyloseelipid complex plays an
important role in retarding the starch retrogradation process and
staling of breads. Cakes with E1 displayed higher hardness than
control cake at the end of the storage time. Fat-replaced cakes had
higher hardness during storage than full fat cakes.
