Before attempting to model the data, we examined how the total degradation (TD) and percent label claim (%LC) changed with time-point. To do so, we plotted these variables, separated by the storage conditions, as a function of time-point (Figure for TD and Figure for %LC). The plot for TD shows a linear trend, which is confirmed by the coefficient of determination (R 2 ) values for each sample (Table ) as 16 out of the 18 samples have an R 2 greater than 0.95 and 13
