Meionly, have you tried > File > Export Setup..., then chose > Rendering? Check "Custom color" and pick a color of your liking, e.g., r for red ( w for white). Hit [Apply to Figure] and then [Export] to .jpg.

OK. In this case you would set up a batch job programmatically, where you open the figures and then use
set(gcf,'color','w');
print(gcf, '-djpeg', 'myFilename.jpg')
to set the background color and export the current figure (gcf) to .jpg.
