The functional property of dietary fiber added to emulsion-type
sausage depended on its gel-forming capacity (Rodriguez Furlan
et al., 2014). Inulin from JAP is known to be semi-crystalline in
nature (Glibowski & Pikus, 2011). Also, the amorphous region can
hydrate, swell to form a gel (Kim, Faqih, & Wang, 2001). Therefore,
the gel-forming capacity of JAP was studied. The FDP formed a gel
at a concentration of 4%. However, the gelation capacity at concentrations
of 6e10% did not vary. In contrast, ODP formed a gel at a
concentration of 12%, but subsequent increases from 12% to 20% led
to a progressive increase in the least gelation concentration.
Because, as the inulin concentration in the solution increases, the
viscosity of the solution increases. Hence, gel formation of FDP and
ODP may depend upon the inulin content of the powder and the
crystallographic structures of the different powders as reported
