a Procedure for each FAME: 1) calculate
ln(IPB) = B0 + B1(298.15
K) [B0 and B1 from Table
4 ]; 2) SLB = inverse natural log of extrapolated
ln(IPB) value.
b Confidence level = 95 %.
The SLB data for CaME, PME and MeC18:1 were an order in
magnitude greater than the corresponding SLA data. For
these three FAME, the SLB values were 4.9, 8.7 and 10.0
times higher than the respective SLA values. The
SLB of SME was 4.1 times greater than its
SLA, while the SLB for MeC18:2 was only
55 % higher than its SLA. It appears the inflation in
the SLB values relative to corresponding
SLA values was larger for the three FAME with high total
MUFAME concentrations (≥ 40.49 mass%). In contrast, FAME with high
total PUFAME concentrations (62.09 % for SME and 99.0 % for MeC18:2)
exhibited smaller increases in SLB, with respect to
SLA. Nevertheless, SLB was consistently
greater than SLA for all five FAME studied in the
present work.
A comparison of SLA results with shelf-life data
reported in two earlier studies is presented in Figure 6 . The
results presented in the present work compared well with the ‘SL(1)’
data reported in an earlier study (Dunn, 2020). In that study,
shelf-life data were obtained by
