I was under the impression saliva is used to "prime" carbohydrates (starches) for later digestion in the gut, and is really only effective if a food is thoroughly chewed. Most carnivores gulp their prey which means saliva is essentially bypassed.

Again, what is the point in obsessing over whether a food retains it's enzymes if those same enzymes are not essential for digestion?
