Thats the whole point of this exercise Phil, to simulate the digestion process, enzymes do have a peak working temperature, about 18 degrees I think, but don't quote me on that, you have to check with Frank on that one. The whole ethos of using enzyme rich baits is to assist the break down before Mr carp even gets to the bait, hence baits being kept in warm flasks. The problem is as soon as these bait are submerged in the temperatures we have, the digestion slows and stops, so if you can emulate and assist the break down, bobs your uncle. The whole thinking being it is, if a bait is more easily digested a fish will eat more. This is the reason for looking at certain enzymes, but you have to remember there are a lot, I think enzymes run into their hundreds.
That's what ive gotten from what ive read any way
