Application

Application Comment Organism
nutrition commercial applications in fruit and vegetable processing, particularly in apple juice manufacture where their use prevents haze formation in pectinase-treated apple pulp by depolymerizing debranched arabinan, linear alpha-1,5-arabinan, formed by the action of alpha-L-arabinofuranosidases during this process Aspergillus niger
