The chemical composition of the sausages
with added chia seed extract and the control were
in accordance with the Standard of Identity and
Product Quality. The mean values of pH in the
different analyzed treatments increased during
the period of storage. At the end of storage, all the
treatments showed a decrease in L
*
values, indicating
darkening of the product. TBARS levels tended to
increase over time in storage. The extract of chia
seeds
(Salvia hispanica)
was efficient regarding
the oxidative stability of the pork sausage. This
was observed from 14 days of storage until the
end of the analysis, when all treatments with added
chia extract had lower oxidation than the control
treatment; the treatment with 2% added chia extract
had the lowest lipid oxidation. The microbiological
analysis was within the tolerance limits established
by Brazilian Legislation for all the treatments. In
the sensory analysis, the mean values of the scores
of the analyzed attributes were “moderately liked.”
The test of intention to purchase showed that there
was no significant difference in intent to purchase
between the control sausage and the sausage with
added extract of chia seed. In general terms, the pork
sausages containing 2% chia seed extract showed
the best results compared to the other concentrations
with regard to lipid oxidation.
