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 SL 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
