Abstract: Mixtures of various starch-degrading enzymes (amylases) which comprise at least one high temperature amylase (HTA) and at least one low temperature amylase (LTA) in an activity ratio of HTA to LTA of 10%:90% to 90%:10% develop at least 60% of their maximum activity in the temperature range from 30.degree. to 90.degree. C. Such mixtures can be diluted with water and treated with customary additives. These mixtures are suitable for desizing textiles sized with starch by treatment of the textiles with the mixtures mentioned and subsequent rinsing.
