There are some proteins in the jelly, they from bonds to build up the structure of the jelly, then the jelly becomes solid. But there is some protease (enzyme) in Fresh kiwi, which breaks drown the protein in the jelly, so the jelly is only half set up. If the concentration of the kiwi is high, may be the jelly can not set up totally.
There is no protease in apply.
