Claims4
A method for the preparation of barley malt flour having enzyme activity comprising the steps of:
- treating barley malt with an aqueous solution of isopropanol for sufficient time to destroy bacteria and at a temperature below that causing heat inactivation of enzymes;
- thereafter removing said aqueous isopropanol from said alcohol treated barley malt;
- washing said alcohol treated barley malt with water to reduce isopropanol residues to less than 50 ppm.;
- exposing said alcohol treated barley malt to temperature sufficient to dry said barley malt without heat inactivating enzymes contained therein;
- and
- milling said alcohol treated barley malt into a flour.
