the total P analysis. All P-containing fractions are expressed as
their P (atomic weight 31) content to facilitate comparisons. The
rest of P was calculated by subtracting the sum of phytate P and
inorganic P from total P.
2.3. Data analysis and statistical treatment
Data were analyzed with the JMP software, version 5 (JMP, a
business unit of SAS, Cary, NC) for analysis of variance (ANOVA)
based on a randomized block model in order to determine the effects
of different processing steps (types of fractions) and ethanol
plants (Plant No.). The Tukey’s HSD (honestly significant difference)
test was conducted for pair-wise comparisons when ANOVA
showed a significant effect at p < 0.05.
