Question 4: Do POE for soy-based products change over time?
The final segment of the analysis focused on whether the volume of
soy-based imports and POE changed over time, once again focusing on
China (Fig. 1a) and the Ukraine (Fig. 1b). To evaluate trends over time,
data were evaluated from 2015 to 2019. Different patterns between
countries were observed, with imports from China demonstrating a
reduction in volume over time with consistent POE, while data from the
Ukraine indicated variability across POE, while the overall volume
imported to the US remained high.
