Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
72 words
A process for preparing a stabilized fungal α-amylase composition suitable for use in the baking industry, which comprises uniformly blending a liquid fungal α-amylase concentrate having a minimum diastatic activity of 12,500 SKB units with a sufficient amount of a dried starch containing a maximum of 3% moisture to obtain a free-flowing fungal α-amylase composition having a diastatic activity of at least 1,000 SKB units/gram thereby obtaining maximum water content of 8.4%.
Claim 2
Dependent Claim
72 words
A process for preparing a stabilized fungal α-amylase composition suitable for use in the baking industry, which comprises uniformly blending a liquid fungal α-amylase concentrate having a minimum diastatic activity of 12,500 SKB units with a sufficient amount of a dried starch containing a maximum of 3% moisture to obtain a free-flowing fungal α-amylase composition having a diastatic activity of at least 1,000 SKB units/gram thereby obtaining maximum water content of 8.4%.
Claim 3
Dependent Claim
21 words
A process according to claim 1 wherein the prepared dry fungal α-amylase composition has a diastatic activity of 5,000 SKB units/gram.
Claim 4
Dependent Claim
13 words
A process according to claim 1 wherein the dried starch is corn starch.
