Preparation of cereal bars
Four formulations of cereal bars containing 0% (F1), 5%
(F2), 10% (F3) and 20% (F4) of linseed in the form of whole
flour and seed were prepared. The percentages were in relation
to total formulation, excluding the water. Soy oil was reduced
in function of the lipid concentration of the seed (table 1).
For the agglutination syrup, brown sugar, corn glucose
and water were heated under agitation in a Teflon® pan
at average temperature of 115ºC, for approximately seven
minutes. Next, the remaining ingredients were heated on a
low flame for five minutes and homogenized to the agglutination
syrup. The content of soy oil added was reduced as
a function of the levels of lipids in linseed. The mixture was
placed in heat-resistant containers and pressed manually.
After cooling at room temperature, the cereal bars were cut
in a rectangular shape, with a constant weight of 25 g and
conditioned individually in polyethylene plastic wrap for
subsequent analyses.
