Abstract
An enzyme composition having a synergetic phytate hydrolyzing activity comprising a phytase having phytate hydrolyzing activity at a pH of from 2.5 to 5.0 and an acid phosphatase having phytate hydrolyzing activity at a pH of 2.5, in a low ratio corresponding to a pH 2.5/5.0 activity profile of from 0.8/1.0 to 3/1. Said enzyme composition preferably displays a higher synergetic phytate hydrolyzing efficiency through thermal treatment. Fungal enzymes, especially those from Aspergillus, are preferred. Use of said enzyme composition in food, feed and fodder products to improve phytate hydrolysis.
Claims14
An enzyme composition having phytate hydrolyzing activity comprising:
- an isolated phylase having a phytate hydrolyzing activity at a pH range from 2.5 to 5.0;
- and
- an isolated acid phosphatase having phytate hydrolyzing activity at a pH of 2.5;
- wherein said phytase and said acid phosphatase and in a mixture in a ratio which provides said mixture with phytate hydrolyzing activity units in a ratio, a/p, wherein a is the activity at pH 2.5 and p is the activity at pH 5.0, of 0.8/1 to 3/1, and wherein said activity unit is the amount of enzyme that liberates one micromole of phosphorus/min. at 40.degree. C., respectively, at pH 2.5 and 5.0.
