Another option which might be cheaper and adequate would be color managed video. You would need a light source with a high CRI such as:

And then calibrate your fixed light/camera setup using standard color test targets and one of the color management tools available for Linux. I
think Gimp or one of it's plug-ins can then give you the average color in
a selected area, and you could determine the acceptable range of RGB
values from measuring known pass/fail samples.
This misses a lot of the information you would get from the complete
spectrum you get from a spectrometer but might be adequate for ripeness evaluation.
