Abstract
Abstract A sweetening agent in particulate form which volume for volume has a sweetening power about equal to that of table granulated sugar (sucrose) and has a calorific value considerably less than that of table granulated sugar, has particles which comprise solid sugar occluded in a glassy matrix which is formed of a water-soluble relatively bland polysaccharide and contains a dissolved non-nutritive sweetener.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
99 words
A sweetening agent is particulate form which volume for volume has a sweetening power about equal to that of table granulated sugar and has a calorific value considerably less than that of table granulated sugar, whose particles consist essentially of solid sugar particles embedded in a glassy matrix of water-soluble relatively bland polysaccharide and a non-nutritive sweetener; said sugar forming one-third to two-thirds by weight, and said non-nutritive sweetener forming 0.25 to 10% by weight, of the particles; the uncompacted bulk density of said particulate-form sweetening agent being in the range of from 0.25 to 0.5 gm/cm 3 .
Claim 2
Dependent Claim
99 words
A sweetening agent is particulate form which volume for volume has a sweetening power about equal to that of table granulated sugar and has a calorific value considerably less than that of table granulated sugar, whose particles consist essentially of solid sugar particles embedded in a glassy matrix of water-soluble relatively bland polysaccharide and a non-nutritive sweetener; said sugar forming one-third to two-thirds by weight, and said non-nutritive sweetener forming 0.25 to 10% by weight, of the particles; the uncompacted bulk density of said particulate-form sweetening agent being in the range of from 0.25 to 0.5 gm/cm 3 .
Claim 3
Dependent Claim
21 words
A sweetening agent according to claim 1, in which the sugar forms from 50 to 60% by weight of the particles.
Claim 4
Dependent Claim
14 words
A sweetening agent according to claim 2, in which the non-nutritive sweetener is saccharin.
Claim 5
Dependent Claim
131 words
A method of making a sweetening agent as set forth in claim 5, comprising a. evaporating to dryness under reduced pressure a suspension of caster sugar particles in an aqueous solution of water-soluble relatively bland polysaccharide and a non-nutritive sweetener, in such concentrations that only a small proportion of the caster sugar is dissolved in said aqueous solution, to obtain a brittle glassy foam; b. subdividing the foam; and c. separating from the subdivided material thus formed, a particulate product in a form that passes through a sieve of aperture size 1.5 mm and is retained on a sieve of aperture size 0.25 to 0.5 gm/cm 3 ; said sugar forming one-third to two-thirds by weight, and said non-nutritive sweetener forming from 0.25 to 10% by weight, of the particulate product.
