Abstract
Abstract The invention relates to a non-cariogenic hydrogenated starch for confectionery and process for preparing this hydrolysate. This hydrogenated starch hydrolysate comprises a content of polyols of DP higher than 20 which is sufficiently low for the cariogenic character of these polyols not to be troublesome and a content of low molecular weight products, which is sufficiently low for their presence not to interfere with the applicability of said hydrolysates in confectionery. The hydrogenated starch hydrolysate can be used in the manufacture of "hard candies" and chewing gums.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
46 words
Non-cariogenic hydrogenated starch hydrolysate for confectionery and chewing-gums, comprising less than 3% of polyols whose DP is higher than 20, 4 to 14% sorbitol, 45 to 60% of maltitol, the balance up to 100% consisting essentially of a mixture of polyols of DP 3 to 20.
Claim 2
Dependent Claim
46 words
Non-cariogenic hydrogenated starch hydrolysate for confectionery and chewing-gums, comprising less than 3% of polyols whose DP is higher than 20, 4 to 14% sorbitol, 45 to 60% of maltitol, the balance up to 100% consisting essentially of a mixture of polyols of DP 3 to 20.
Claim 3
Dependent Claim
17 words
Hydrolysate according to claim 1, comprising less than 1.5% of products whose DP is higher than 20.
Claim 4
Dependent Claim
11 words
Hydrolysate according to claim 1, comprising 5 to 8% of sorbitol.
Claim 5
Dependent Claim
11 words
Hydrolysate according to claim 1, comprising 50 to 53% of maltitol.
Claim 6
Dependent Claim
27 words
Hydrolysate according to claim 1, comprising: less than 1.5% of products whose DP is higher than 20, 5 to 8% of sorbitol, 50 to 53% of maltitol.
Claim 7
Dependent Claim
110 words
Process for the preparation of a non-cariogenic hydrogenated hydrolysate for confectionery and chewing-gums, in which a starch hydrolysate of a D.E. of 17 to 27 obtained by acid or enzymatic hydrolysis is submitted successively to the steps comprising: the action of a β-amylase and the action of an α-amylase, the amounts of α-amylase and of β-amylase and the duration of action of these two enzymes being selected so that the D.E. of the hydrolysate is brought to a value of 46 to 48 at the end of the first enzymatic treatment and to a value of 48 to 50 at the end of the second, the final hydrolysate being hydrogenated.
Claim 8
Dependent Claim
110 words
Process for the preparation of a non-cariogenic hydrogenated hydrolysate for confectionery and chewing-gums, in which a starch hydrolysate of a D.E. of 17 to 27 obtained by acid or enzymatic hydrolysis is submitted successively to the steps comprising: the action of a β-amylase and the action of an α-amylase, the amounts of α-amylase and of β-amylase and the duration of action of these two enzymes being selected so that the D.E. of the hydrolysate is brought to a value of 46 to 48 at the end of the first enzymatic treatment and to a value of 48 to 50 at the end of the second, the final hydrolysate being hydrogenated.
Claim 9
Dependent Claim
43 words
Process according to claim 6, wherein the hydrolysate whose D.E. is 48 to 50, is submitted to the conjugate action of a β-amylase and of an enzyme hydrolyzing the 1-6 linkages of the amylopectin to further reduce polysaccharides of DP greater than 20.
Claim 10
Dependent Claim
82 words
Process for the preparation of a non-cariogenic hydrogenated hydrolysate for confectionery and chewing-gums, wherein a starch hydrolysate of a D.E. of 17 to 27, obtained by acid or enzymatic hydrolysis, is submitted successively to the steps comprising saccharification by means of a β-amylase until a D.E. of 46-48 is obtained and then to a fractionation by passage through a cationic resin, or through a molecular sieve to remove polysaccharides whose DP is higher than 20, the thus obtained syrup then being hydrogenated.
Claim 11
Dependent Claim
82 words
Process for the preparation of a non-cariogenic hydrogenated hydrolysate for confectionery and chewing-gums, wherein a starch hydrolysate of a D.E. of 17 to 27, obtained by acid or enzymatic hydrolysis, is submitted successively to the steps comprising saccharification by means of a β-amylase until a D.E. of 46-48 is obtained and then to a fractionation by passage through a cationic resin, or through a molecular sieve to remove polysaccharides whose DP is higher than 20, the thus obtained syrup then being hydrogenated.
Claim 12
Dependent Claim
14 words
Process according to claim 8, wherein the cationic resin is in the calcium form.
Claim 13
Dependent Claim
126 words
Process according to any one of claims 6 and 7, wherein the amount of the enzymes and the conditions of action of the enzymes comprises: β-amylase: 200 to 1000 international units per kg of dry substrate, pH 5.0 to 6.0 temperature 50° to 60° C., duration of action 30 to 72 hours; α-amylase: 16,000 to 48,000 international units per kg of dry substrate, pH 5.0 to 6.0, temperature 50° 60° C., duration of action 16 to 30 hours; enzyme hydrolyzing 1-6 linkages: 120 to 400 international units per kg of dry substrate, in the presence of 50 to 100 international units of β-amylase per kg of dry substrate, pH of 5.0 to 6.0, temperature of 50° to 60° C., duration of action 24 to 48 hours.
