Abstract

An enzyme system is described that is useful for preparing food and feed. One enzyme of that system is obtainable from Aspergillus. That enzyme has the following characteristics: a MW of from 29 kDa to 36 kDa as measured on a SDS-Phastgel (10-15%) or about 30 kDa; a pI value of about 3-4; ferulic acid esterase activity; a pH optimum of about 5; and a temperature optimum of from about 50 to about 60.degree.
