Abstract
Abstract The present invention provides a process for preparing low D.E. starch hydrolysates and low D.E. conversion syrup products which are both liquid and solid. Starch is treated with bacterial alpha amylase to a D.E. less than 15. The hydrolytic action of the amylase is terminated by heat treatment and the resulting hydrolysate is further converted with bacterial alpha amylase to a D.E. between about 5 and about 20. From the resulting hydrolysate product is obtained a non-hazing syrup which is substantially completely water soluble.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
A non-waxy cereal starch hydrolyzate having a dextrose equivalent value in the range from about 5 to about 20, and being characterized in that the observed value of A for a given product does not exceed by more than 25% the value of A that is calculated from one of the following equations for a product having the dextrose equivalent value of the given product, wherein A is the iodine absorbency value at 500 millimicrons expressed on a 5 centimeter cell basis and calculated to a concentration of 1 milligram of dry substance per milliliter: Equation 1: when the dextrose equivalent value is from about 5 to about 10: log A=-0.1830 dextrose equivalent value+2.606, and Equation 2: when the dextrose equivalent value is from about 10 to about 20: log A=-0.0905 dextrose equivalent value+1.683.
Claim 2
Dependent Claim

A non-waxy cereal starch hydrolyzate having a dextrose equivalent value in the range from about 5 to about 20, and being characterized in that the observed value of A for a given product does not exceed by more than 25% the value of A that is calculated from one of the following equations for a product having the dextrose equivalent value of the given product, wherein A is the iodine absorbency value at 500 millimicrons expressed on a 5 centimeter cell basis and calculated to a concentration of 1 milligram of dry substance per milliliter: Equation 1: when the dextrose equivalent value is from about 5 to about 10: log A=-0.1830 dextrose equivalent value+2.606, and Equation 2: when the dextrose equivalent value is from about 10 to about 20: log A=-0.0905 dextrose equivalent value+1.683.
Claim 3
Dependent Claim
18 words
A non-waxy cereal starch hydrolyzate in accordance with claim 1 wherein said non-waxy cereal starch is corn starch.
Claim 4
Dependent Claim
176 words
A non-waxy cereal starch hydrolyzate having a dextrose equivalent value in the range from about 5 to about 20, a descriptive ratio of at least about 2.0, wherein said descriptive ratio is the quotient obtained by dividing the sum of the percentages of saccharides, dry basis, having a degree of polymerization of 1 to 6, by the dextrose equivalent value, and being further characterized in that the observed value of A for a given product does not exceed by more than 25% the value of A that is calculated from one of the following equations for a product having the dextrose equivalent value of the given product, wherein A is the iodine absorbency value at 500 millimicrons expressed on a 5 centimeter cell basis and calculated to a concentration of 1 milligram of dry substance per milliliter: Equation 1: when the dextrose equivalent value is from about 5 to about 10: log A=-0.1830 dextrose equivalent value+2.606, and Equation 2: when the dextrose equivalent value is from about 10 to about 20: log A=-0.0905 dextrose equivalent value+1.683.
Claim 5
Dependent Claim
176 words
A non-waxy cereal starch hydrolyzate having a dextrose equivalent value in the range from about 5 to about 20, a descriptive ratio of at least about 2.0, wherein said descriptive ratio is the quotient obtained by dividing the sum of the percentages of saccharides, dry basis, having a degree of polymerization of 1 to 6, by the dextrose equivalent value, and being further characterized in that the observed value of A for a given product does not exceed by more than 25% the value of A that is calculated from one of the following equations for a product having the dextrose equivalent value of the given product, wherein A is the iodine absorbency value at 500 millimicrons expressed on a 5 centimeter cell basis and calculated to a concentration of 1 milligram of dry substance per milliliter: Equation 1: when the dextrose equivalent value is from about 5 to about 10: log A=-0.1830 dextrose equivalent value+2.606, and Equation 2: when the dextrose equivalent value is from about 10 to about 20: log A=-0.0905 dextrose equivalent value+1.683.
Claim 6
Dependent Claim
