Based on the results of the present investigation, we conclude
that the types of gels and their preparation conditions have profound
effect on their gel characteristics, thus influencing the
structure and the selected quality attributes of microwave vacuum
dried products derived from those gels. Mixed starch with fish
dough with medium moisture content can be formed into a homogenous
co-gel with good springiness and cohesiveness and
medium hardness at the high severity of the thermal treatment,
which can be transformed to a uniformly expanded, porously
structural snack food product with good crispness and satisfied
sensory quality by microwave vacuum drying technique. Although
the higher severity of the thermal treatment, viz.,100 C for 60 min,
favors more expansion and better sensory quality, it leads to an
excessively adhesive gel, thus causing poor cutting efficiency.
Further research is required to ascertain how the ratio of protein
and starch, salt and cold storage might affect the quality
