  • Patent number: 5578335
    Abstract: The present invention discloses the application of a pectin esterase substantially free from depolymerase activity in the maceration of apple pulp. The use of purified pectin esterase leads to a low amount of pectin degradation products in the juice and to the conservation of protopectin in the apple pomace. Furthermore, the juice yield and the pressability are increased through the use of purified PE.
