Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
76 words
A process for the simultaneous production of ethyl alcohol and fructose polymers which comprises contacting a sucrose-containing substrate at a temperature of about 20° C. to about 35° C. and a pH of about 4.0 to about 6.5 with a mixture of an effective amount of fructosyl transferase enzyme and an effective amount of a yeast preparation, that does not hydrolyze sucrose or fructose polymers or ferment fructose polymers, to produce fructose polymers and ethyl alcohol.
Claim 2
Dependent Claim
76 words
A process for the simultaneous production of ethyl alcohol and fructose polymers which comprises contacting a sucrose-containing substrate at a temperature of about 20° C. to about 35° C. and a pH of about 4.0 to about 6.5 with a mixture of an effective amount of fructosyl transferase enzyme and an effective amount of a yeast preparation, that does not hydrolyze sucrose or fructose polymers or ferment fructose polymers, to produce fructose polymers and ethyl alcohol.
Claim 3
Dependent Claim
28 words
The process of claim 1 wherein said yeast preparation is a Saccharomyces, said substrate is sucrose and said fructosyl transferase enzyme preparation is obtained from a Pullularia pullulans.

Claim 5
Dependent Claim
44 words
The process of claim 3 wherein said yeast preparation is Saccharomyces bailli, ATCC No. 28166, and the reaction is carried out at a temperature of from about 24° C. to about 32° C. and at a pH of from about 5.0 to about 5.5.
Claim 6
Dependent Claim
44 words
The process of claim 3 wherein said yeast preparation is Saccharomyces cerevisiae, ATCC No. 20597, and the reaction is carried out at a temperature of from about 24° C. to about 32° C. and at a pH of from about 5.0 to about 5.5.
Claim 7
Dependent Claim
56 words
The process of claim 1 wherein said fructosyl transferase enzyme preparation is derived from Pullularia pullulans, ATCC No. 9348, and said yeast is Saccharomyces bailii, ATCC No. 28166, and the reaction is carried out at a temperature of from about 24° C. to about 32° C. and at a pH of about 5.0 to about 5.5.
Claim 8
Dependent Claim
42 words
The process of claim 1 wherein said yeast is Saccharomyces cerevisiae, ATCC No. 20597, and the reaction is carried out at a temperature of from about 24° C. to about 32° C. and at a pH of about 5.0 to about 5.5.
Claim 9
Dependent Claim
106 words
A process for the production of a high fructose syrup and ethyl alcohol which comprises: (a) contacting a sucrose-containing substrate at a temperature of about 20° C. to about 35° C. and a pH of about 4.0 to about 6.5 with a mixture of an effective amount of a fructosyl transferase enzyme and an effective amount of a yeast preparation, that does not hydrolyze sucrose or fructose polymers or ferment fructose polymers, to produce a mixture of fructose polymers and ethyl alcohol; and (b) treating the resulting mixture with a reagent capable of hydrolyzing polysaccharides to monosaccharides to yield a syrup whose principal sugar is fructose.
Claim 10
Dependent Claim
106 words
A process for the production of a high fructose syrup and ethyl alcohol which comprises: (a) contacting a sucrose-containing substrate at a temperature of about 20° C. to about 35° C. and a pH of about 4.0 to about 6.5 with a mixture of an effective amount of a fructosyl transferase enzyme and an effective amount of a yeast preparation, that does not hydrolyze sucrose or fructose polymers or ferment fructose polymers, to produce a mixture of fructose polymers and ethyl alcohol; and (b) treating the resulting mixture with a reagent capable of hydrolyzing polysaccharides to monosaccharides to yield a syrup whose principal sugar is fructose.
Claim 11
Dependent Claim
