The
data support the extraction of flaxseed gum from the hull. The high yield
suggests that the hull to water ratio of 1:35
(wt/v) was an ideal extraction medium. The higher water level is needed compare
to the 1:13 ratio (wt/v)
reported in the literature due to the initially higher gum concentration in the
hull vs the whole seed as reported in the literature.
Drying using a tray or vacuum kettle proved to be feasible. The viscosity at
low concentrations had a Newtonian-like behavior while concentrations greater
than 0.25 % acted in a non-Newtonian manner. The application of 0.125% flaxseed
gum can be used as a stabilizer in ice cream without impacting textural aspects
of the ice cream. The 0.25% could be used as an effective stabilizer in novelty
ice cream products.
