the increases of gelling and melting temperatures are due to the increasing number of chemical junctions responsible for the formation of the amide bonds (Saito et al.,
2007). Yan et al. (2011)reported that gelatin gels from walleye
pollock skin added with gallic acid (10e40 mg g
1
) and rutin
(2e8mgg1
) had gelling temperature of 4e6
C and the melting
temperature of 11e13
C. Therefore, the addition of EECH at an
appropriate level could increase gelling point, in which gel could be
formed easier than the control. Also gel was maintained for a longer
time as indicated by the higher melting temperature. Generally, the
melting point was higher than the gelling point because gelatin gel
absorbed energy when it was melting (Liu, Li,&Guo, 2008)
