2.2.5.2. Statistical analysis. The JMP 9.0 software was used to
analyze the data. Statistical model tested the significant differences
(a ¼ 0.05) in pH, peptide concentration, color, total soluble solids,
and ascorbic acid concentration between treatments over storage
time. If significant changes were observed between treatments
throughout storage, the experiment was repeated by including a
contrast of the response at day 0 over the storage period for
determining the reason for the change.
