Claims
- 1. A mixed enzyme product comprising a mixture of the alpha-amylase from Bacillus licheniformis and the alpha-amylase from B. stearothermophilus, said mixture containing from 25%-90% by activity as NU/g DS of the Bacillus licheniformis enzyme.
- 2. In a process for liquefying starch or starchy grains which comprises subjecting an aqueous slurry of 32-38% dry substance by weight and an alpha-amylase in dosage of from 20-80 NU/g dry starch to jet cooking at a temperature in the range of 100.degree. C.-115.degree. C. for 1-60 minutes, followed by reducing temperature to a temperature in the range of 90.degree. C.-100.degree. C. for 30-180 minutes after which so liquefied starch is stable against retrogradation, the improvement which comprises conducting said liquefaction in the range of about pH 5.5-6.2 with an enzyme mixture of the alpha-amylase from Bacillus licheniformis and the alpha-amylase from B. stearothermophilus containing from 10%-90% by activity as NU/g DS of the Bacillus licheniformis enzyme.
- 3. A mixed enzyme product as in claim 1 containing from 25-75% of the Bacillus licheniformis enzyme.
- 4. A liquefying process as in claim 2 which further comprises liquefying with an enzyme mixture containing from 25-90% of the Bacillus licheniformis enzyme.
- 5. A liquefying process as in claim 2 which further comprises liquefying with an enzyme mixture containing from 25-75% of the Bacillus licheniformis enzyme.
- 6. A liquefying process as in claim 2 which further comprises liquefying with an enzyme mixture containing about 2/3 thereof of the Bacillus licheniformis enzyme at a pH in the range of about pH 5.8-6.0.
- 7. A mixed enzyme product comprising a mixture of the alpha-amylase from Bacillus licheniformis and the alpha-amylase from B. stearothermophilus, said mixture containing about 2/3 by activity as NU/g DS of the Bacillus licheniformis enzyme.
