ABSTRACT:
A liquid enzyme concentrate containing the alpha-amylase from Bacillus licheniformis and optionally a proteinase dissolved in 40-95% by weight propylene glycol 1,2 balance water, at pH 5-9, the enzyme activity being 10-1000 KNU/g of concentrate.
Proteinase may be present in activity of 0.5-6.5 Anson units/g of concentrate. Subtilisin Carlsberg is a preferred proteinase, and in such instance, appropriate stabilizers for the proteinase are included in the concentrate.
