where Yf(t) is the pAV on a given day, Arepresents contribution from stable interfering components that respond
to the pAV reagent but do not change over time, B represents the
aldehydes that respond to pAV reagent and change over the course of
oxidation either due to lipid oxidation or aldehyde degradation,k is the rate constant for aldehyde formation, and t is
the time. Pooled-variance t-tests (df=30, α=0.05) were used to comparek , A , and B between different treatments. On each
testing day, treatment effect was evaluated with one-way analysis of
variance (ANOVA), followed by a post-hoc Tukey test with a significance
level of 0.01.
