Without knowing what kind of soup or how you are eating it, I will relay this story:While doing R&D in my early years, my supervisor commented that sometimes his new Instant Spaghetti Sauce would get watery upon sitting. It turns out that he would taste some and put his spoon back into the sauce. He used a pre-gellatinized starch and the enzymes carried from his mouth via the spoon to the sauce actually started the digestion process and broke down the hydrated starch which resulted in a watery sauce.
