SALT-STABILIZED ENZYME PREPARATIONS

摘要

The present invention discloses methods to improve the processing and storage stability of dry enzyme preparations. To this extent an inorganic salt, e.g. MgSO4, is dissolved in an enzyme containing solution which is subsequently dried, using e.g. spray drying. Not only does the addition of salt improve the yield of enzyme activity upon drying, but also the storage and processing stability of the obtained solid composition containing the enzyme and the inorganic salt are improved with respect to enzyme activity. The invention further discloses solid compositions comprising enzymes and inorganic salts.
