Abstract
Abstract The invention relates to the preparation of a high maltose syrup containing from 60 to 80% maltose, from 12 to 24% glucose and from 8 to 16% sugars having a DP of three or more by the enzymatic saccharification of partially hydrolyzed starch having a dextrose equivalence of from 1 to about 30; the high maltose syrups obtained from such process; the hydrogenation of such high maltose syrup to form maltitol blends containing from 60 to 80% maltitol and from 12 to 24% sorbitol; and the so prepared maltitol blends, such blends having a desired combination of high sweetness and humectancy.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A process for the saccharification of a partially hydrolyzed starch having a DE of from 1 to 30, comprises contacting such partially hydrolyzed starch under saccharification conditions with from 0.1 to 1 wt. % of a three-component enzyme composition, said three-component enzyme composition containing from about 30 to 50 wt. % each of beta-amylase and alpha-1,6-glucosidase and from 10 to 40 wt. % of fungal alpha-amylase, so as to form a polysaccharide composition containing from 60 to 80 wt. % maltose, from 12 to 24 wt. % glucose, and from 8 to 16 wt. % saccharides having a DP of 3 or more.
Claim 2
Dependent Claim
103 words
A process for the saccharification of a partially hydrolyzed starch having a DE of from 1 to 30, comprises contacting such partially hydrolyzed starch under saccharification conditions with from 0.1 to 1 wt. % of a three-component enzyme composition, said three-component enzyme composition containing from about 30 to 50 wt. % each of beta-amylase and alpha-1,6-glucosidase and from 10 to 40 wt. % of fungal alpha-amylase, so as to form a polysaccharide composition containing from 60 to 80 wt. % maltose, from 12 to 24 wt. % glucose, and from 8 to 16 wt. % saccharides having a DP of 3 or more.
Claim 3
Dependent Claim
23 words
The process of claim 1, wherein the partially hydrolyzed starch is a maltodextrin, a waxy maize syrup, or a low conversion corn syrup.
Claim 4
Dependent Claim
47 words
The process of claim 1, wherein the saccharification takes place in an aqueous solution containing less than 45% of solids at a pH of from 4.5 to 6, at a temperature of from 45° to 60° C., and a reaction time of from 36 to 144 hours.
Claim 5
Dependent Claim
112 words
A process for the preparation of a high maltitol syrup which comprises: saccharifying a partially hydrolyzed starch having a DE of from 1 to 30 in the presence of from 0.1 to 1 wt. % of a three-component enzyme composition, said three-component enzyme composition comprising from about 30 to 50 wt. % each of beta-amylase and alpha-1,6-glucosidase and from 10 to 40 wt. % of fungal alpha-amylase, and thereafter hydrogenating the product of said saccharification step to form a hydrogenated starch hydrolysate containing 12 to 24 wt. % sorbitol, from 60 to 80 wt. % maltitol, and from 8 to 16 wt. % hydrogenated saccharides having a DP of 3 or more.
Claim 6
Dependent Claim
112 words
A process for the preparation of a high maltitol syrup which comprises: saccharifying a partially hydrolyzed starch having a DE of from 1 to 30 in the presence of from 0.1 to 1 wt. % of a three-component enzyme composition, said three-component enzyme composition comprising from about 30 to 50 wt. % each of beta-amylase and alpha-1,6-glucosidase and from 10 to 40 wt. % of fungal alpha-amylase, and thereafter hydrogenating the product of said saccharification step to form a hydrogenated starch hydrolysate containing 12 to 24 wt. % sorbitol, from 60 to 80 wt. % maltitol, and from 8 to 16 wt. % hydrogenated saccharides having a DP of 3 or more.
