Speaking as someone who works on a gastric pathogen in a GI lab... yes and no.
The retention of a particular structure (the afore-deleted sweetcorn being a perfect example) after both mastication and gastric processing doesn't mean that it's not of any further nutritional benefit. Depending on what microflora you have in your lower GI tract, you may be extracting more nutrients as the bacteria take a whack at it, especially through the large intestine.
And re: a more digestive-juice-like mixture, can you purchase powdered meat tenderizer any more? That's usually a mixture of digestive enzymes (papain, calpain, collagenase) purified up from sundry sources (papaya, pineapple, some bacteria, some intestines, and so on).
Hrmm, there's an interesting idea for a public experiment. Take some of the more exotic fruits, juice them fresh, and test them for protease/collagenase abilities.
