Well, blueberries aren't fully dark throughout, their pigments are concentrated in the skin (which incidentally is why black raspberry and even some blackberries are higher in anthocyanin concentration). I'm not sure how they are processed for jams and jellies but I have a feeling they leave them as is. I suppose they may add additional color but I don't think they bleach them first. Perhaps one reason why is with strawberries the fruit is cut up so you would end up with some all white pieces and some pieces that are half white and half colored. You don't typically see that with blueberry jams. The fruit is often whole or mashed, and when mashed the dark pigments tend to bleed most of it pretty dark in a hurry. Anyone else know about how blueberries are processed for jam commercially?
As for raspberries, they aren't typically bleached and died, instead relying on the natural color. This is one reason why darker raspberries (such as 'Willamette') have almost always been favored for the processing market, and this is an important consideration that all three breeding programs here in the Pacific Northwest factor in when evaluating red raspberries. The lighter and brigher colored berries are more attractive to consumers on the fresh market while the darker cultivars tend to be used more for processing. Of course there are other factors too, for example how easily a berry machine harvests will determine whether it has to be hand-picked (usually fresh market sales where the higher price can offset the increased cost of labor and because machine harvested berries are too bruised and soft for fresh market sales) or can be machine harvested (processed for a lower price but much lower cost as well), but color of both
whole fruit and puree is something we look at very closely in advanced selections for raspberry.
